Rickets is a condition in children where growing bones become soft and weak, most often because the body does not get enough vitamin D, calcium, or phosphate. Early symptoms of rickets can include bone pain, delayed growth, muscle weakness, and trouble walking, and some children develop bowed legs or other bone changes over time. It may help to know that doctors have studied this condition for decades, and rickets is usually treatable when the cause is found early. Treatment often includes vitamin D or mineral supplements, changes to diet, and safe sunlight exposure, while some children need treatment for an underlying medical problem. Severe untreated rickets can lead to lasting bone problems, but death from rickets is uncommon in places where medical care is available.
How many people live with Rickets?
There is no single reliable current count of how many people are living with rickets worldwide or in the United States. Rickets is usually measured in local studies of children rather than as one national or global total, and the numbers can vary a lot depending on the country and on how doctors define the condition.
Overview
RicketsSymptoms
Rickets can cause bone pain, delayed growth, and weak, soft bones. Many children develop bowed legs or other changes in bone shape. Early symptoms of rickets can include muscle weakness and trouble walking.
Outlook and prognosis
With prompt treatment, most children with rickets have stronger bones, less pain, and better growth. The outlook for rickets is usually very good, though long-standing or severe cases can leave some bone shape changes or short height.
Causes and risk factors
Rickets usually results from too little vitamin D, calcium, or phosphate. Risk rises with limited sunlight, darker skin, poor diet, malabsorption, kidney or liver disease, and some medicines. Rarely, inherited gene changes cause certain forms of rickets.
Genetic influences
Genetics can be very important in rickets. While many cases are not inherited, some forms run in families because gene changes affect how the body handles vitamin D, phosphate, or bone mineralization.
Diagnosis
Doctors diagnose rickets using a physical exam, blood tests, and X-rays to look for changes in growing bones. If the cause is unclear, the diagnosis of rickets may also include tests for vitamin D, calcium, phosphate, or, less often, genetic tests.
Treatment and drugs
Rickets treatment aims to strengthen growing bones and ease pain. Many with rickets need vitamin D and calcium, and some also need phosphate. Doctors also treat the cause, such as poor absorption, kidney disease, or low sunlight exposure.
Symptoms
Rickets often comes to attention when a child seems sore, tires more easily, or is not growing as expected. The early symptoms of rickets can be easy to miss because they may look like ordinary growing pains or delayed strength. Symptoms vary from person to person and can change over time. As it goes on, rickets may affect how a child stands, walks, and uses their arms and legs in daily play.
Aching or tenderness often affects the legs, hips, pelvis, or lower back. Some children with rickets avoid running, climbing stairs, or being picked up because it hurts.
Muscle weakness can make it harder to stand up from the floor, walk long distances, or keep up with other children. In babies and toddlers, this may show up as floppiness or slower physical milestones.
Rickets can lead to slower growth and a shorter height than expected for age. Parents may notice clothes sizes change more slowly or that a child seems smaller than peers over time.
Soft bones can bend under body weight, leading to bowed legs, knock knees, or a waddling walk. These changes often become more noticeable once a child starts standing and walking.
How people usually first notice Rickets?
Many people first notice rickets when a baby or young child seems slower to sit, crawl, stand, or walk, or when there is unexplained bone pain, muscle weakness, or unusual fussiness. As the condition progresses, families or doctors may see first warning signs such as bowed legs, wrists that look wider than usual, slower growth, or teeth coming in late, because the bones are not hardening the way they should. If you are wondering how rickets is first noticed, it is often through this mix of delayed development, bone changes, and growth concerns that leads to a medical checkup.
Types of Rickets
Rickets can affect day-to-day life in different ways, from delayed walking to bone pain, bowed legs, or slower growth. The main types of rickets are usually defined by the underlying cause, such as too little vitamin D or phosphate, problems handling these nutrients in the kidneys, or rare inherited changes that affect how the body uses vitamin D. Symptoms don’t always look the same for everyone. Some forms mainly affect growing bones, while others are more likely to come with dental problems, muscle weakness, or symptoms that keep returning despite standard treatment.
Nutritional rickets
This is the most common type and happens when the body does not get enough vitamin D, calcium, or both. Many living with nutritional rickets develop soft, weak bones that can cause bowed legs, bone pain, delayed growth, or trouble walking. It often improves when the deficiency is treated.
Hypophosphatemic rickets
This type is usually inherited and happens when the body loses too much phosphate, a mineral bones need to harden properly. People with hypophosphatemic rickets often have leg bowing, short stature, bone or joint pain, and dental problems such as frequent abscesses. Having one type doesn’t necessarily mean you’ll develop the others.
Vitamin D-dependent rickets
These rare inherited variants of rickets happen when the body cannot properly activate vitamin D or respond to it as it should. Symptoms can look similar to nutritional rickets, with weak bones, poor growth, and muscle weakness, but they usually do not improve with standard vitamin D alone. Some forms may also cause low calcium symptoms such as cramps or seizures.
Renal rickets
This type develops when chronic kidney problems disrupt the balance of vitamin D, calcium, and phosphate needed for healthy bones. Children may have bone pain, poor growth, bowed legs, or delayed motor milestones, along with other signs of kidney disease. For many, this can mean symptoms continue unless both the bone problem and the kidney condition are treated.
Can I slow down the onset of symptoms?
Yes, sometimes: when rickets is caused by too little vitamin D or calcium, making sure a child gets enough of both early on can meaningfully lower the chance that symptoms start, although it cannot guarantee prevention. This is about reducing risk, not fully stopping the condition, and it usually does not prevent symptom onset in rare inherited forms of rickets, where the body has trouble using these nutrients properly. For babies and children at risk, doctors often recommend early checkups and vitamin D supplements, and getting advice early can help even though it cannot promise a specific outcome.
What genetics can tell you about symptoms
Genetics can sometimes help explain the symptoms of rickets, especially in inherited forms where a change in a gene affects how the body handles vitamin D, phosphate, or bone mineralization. In those cases, genes may influence which problems show up, such as bone pain, bowed legs, poor growth, muscle weakness, or dental issues, and they can also affect how early symptoms begin and how severe they become. That said, many cases of rickets are not inherited and happen mainly because of low vitamin D, low calcium, or low phosphate, so genetic testing is most useful when symptoms start early, are unusually severe, or do not improve as expected with standard treatment.
Causes and risk factors
Rickets usually happens when growing bones do not get enough vitamin D, calcium, or phosphate. Low sunlight, a diet low in these nutrients, and some gut, liver, or kidney problems can all raise the risk. Common risk factors for rickets include being born early, having darker skin, and being breastfed without vitamin D supplements. Some risks are modifiable, meaning you can change them, and others are not. Rarely, rickets is caused by an inherited gene change that affects how the body handles vitamin D or phosphate.
What are the most common causes or risk factors?
Most rickets happens when a growing child does not get enough vitamin D, calcium, or a mineral called phosphorus, so the bones cannot harden the way they should. Risk is higher with very little sun exposure, darker skin, poor diet, breastfeeding without vitamin D drops, or health problems that make it hard for the gut, liver, or kidneys to absorb or handle these nutrients. A smaller number of children have inherited forms of rickets caused by gene changes that affect how the body uses vitamin D or keeps the right phosphorus balance.
Environmental and biological risk factors
Rickets becomes more likely when a growing child cannot make, absorb, or use enough vitamin D, calcium, or phosphate. Doctors often group risks into internal (biological) and external (environmental). When people search for what causes rickets in children, these are the patterns doctors pay the most attention to.
Not getting enough sunlight reduces the skin's ability to make vitamin D. This is more common in places with long winters, less year-round sun, or heavy air pollution.
Skin with more melanin makes less vitamin D from the same amount of sunlight. In lower-sun environments, this can raise the risk of rickets.
Babies born early have had less time to build up vitamin D, calcium, and phosphate stores before birth. Because their bones are growing quickly, shortages may affect them sooner.
Infancy and early childhood are times when bones need a steady supply of minerals and vitamin D. If the body cannot meet those demands, rickets can develop more easily.
Genetic risk factors
Rickets can sometimes run in families when an inherited gene change affects how the body uses vitamin D or handles phosphate and calcium. Some risk factors are inherited through our genes. Because several different genes can be involved, the genetic causes of rickets are not all the same, and some children are the first in a family to be diagnosed. A family history of bowed legs, poor growth, repeated fractures, or early dental problems can make inherited rickets more likely.
Family history: Rickets is more likely to have a genetic cause when close relatives have had bowed legs, short stature, repeated fractures, or unexplained dental problems. This pattern can be subtle, so even a limited family history can matter.
X-linked form: The most common inherited form of rickets is X-linked hypophosphatemia, usually caused by a change in the PHEX gene. It can be passed from an affected parent to a child, and girls as well as boys can be affected.
Dominant inheritance: Some gene changes, including certain changes in FGF23, can cause rickets when just one altered copy is present. When this happens, an affected parent may pass the condition to about half of their children.
Recessive inheritance: Other forms of rickets appear only when a child inherits two altered copies of a gene, one from each parent. Parents are often healthy carriers and may not know this risk is present.
Vitamin D activation: Changes in genes that help convert vitamin D into its active form can lead to rickets even when the body has vitamin D available. These forms often start in infancy or early childhood and are usually inherited in a recessive pattern.
Vitamin D response: Rare gene changes can make the body less able to respond to vitamin D, a problem known medically as vitamin D resistance. This form of rickets may cause more severe bone problems, and some children also have hair loss.
Phosphate transport: Inherited changes in genes that move phosphate through the kidneys can lower phosphate levels and weaken growing bones. In some families, this type of rickets is also linked with high calcium in the urine or kidney stones.
New gene changes: Sometimes the gene change behind rickets happens for the first time in a child and is not inherited from either parent. This can explain genetic rickets even when there is no clear family history.
Lifestyle risk factors
Several daily habits can raise the chance of rickets or make it harder for growing bones to mineralize normally. When people ask about lifestyle risk factors for rickets, the most important issues are eating patterns, supplement use, and routines that reduce vitamin D support during childhood. These factors matter most in infants, children, and adolescents during periods of rapid growth.
Diets that provide very little vitamin D can increase the risk of rickets because the body cannot absorb calcium efficiently. This is more likely when fortified foods, oily fish, eggs, or recommended vitamin D supplements are regularly missing.
Poor calcium intake can weaken bone mineralization and contribute directly to rickets, even when vitamin D status is borderline. Diets low in dairy foods or other calcium-rich alternatives can leave growing bones without enough raw material to harden properly.
Highly selective eating, vegan diets without careful planning, or exclusion diets can lower intake of both vitamin D and calcium. Over time, these habits may increase the risk of rickets during growth unless nutrients are replaced appropriately.
Skipping recommended vitamin D supplements in infancy or other high-risk periods can make deficiency more likely. This is especially important for breastfed infants if vitamin D supplementation is not provided as advised.
Risk prevention
Rickets can often be prevented by making sure growing bones get enough vitamin D, calcium, and, when needed, medical follow-up. This matters most for babies, children, and teens during fast growth, when soft bones can lead to bowed legs, bone pain, delayed growth, or trouble reaching motor milestones. Prevention is about lowering risk, not eliminating it completely. Rare inherited forms of rickets are different, and in those cases prevention usually focuses on reducing complications rather than stopping the condition itself.
Getting enough vitamin D is one of the main ways to help prevent rickets. Babies who are breastfed and some children with low intake often need supplements because food and sunlight alone may not be enough.
Strong bone growth also depends on enough calcium from milk, yogurt, fortified plant drinks, tofu, or other calcium-rich foods. If calcium intake stays low for months, a child may be more likely to develop early symptoms of rickets such as bone pain, delayed growth, or legs that begin to curve.
Sunlight helps the skin make vitamin D, but the amount needed varies with skin tone, season, latitude, clothing, and sunscreen use. Because too much sun can harm the skin, many families rely on diet and supplements rather than sun exposure alone.
Babies are at higher risk of rickets if they are exclusively or partly breastfed without vitamin D supplementation. Premature babies and infants with darker skin may need especially careful guidance from their clinician.
Can you prevent Rickets?
Rickets can often be prevented, especially when it is caused by not getting enough vitamin D or calcium. For many children, this means a balanced diet, vitamin D supplements when a doctor recommends them, and safe time in sunlight, since sunlight helps the body make vitamin D. But prevention is not always possible, because some rare forms are caused by inherited conditions and do not respond to these steps in the usual way.
Transmission
Rickets is not contagious, so it cannot be passed from one person to another through coughing, touching, sharing food, or close contact. Most rickets develops because growing bones are not getting enough vitamin D, calcium, or phosphate, often related to diet, limited sun exposure, or certain health conditions.
A smaller number of people have inherited forms of rickets, and how rickets is inherited depends on the specific gene change involved, so it can sometimes be passed from a parent to a child. In day-to-day life, though, people with rickets do not pose any infection risk to others.
When to test your genes
Genetic testing is worth discussing if rickets appears early, keeps coming back, does not improve with vitamin D or calcium, or runs in your family. It can help uncover inherited forms, such as phosphate-wasting or vitamin D metabolism disorders, so care can be tailored more precisely.
Diagnosis
Rickets is usually diagnosed when a child has bone pain, delayed growth, bowed legs, or other changes that raise concern during a medical visit. Doctors usually begin with a physical exam and a careful review of diet, growth, time spent in sunlight, and any health problems that could affect vitamin D or mineral absorption. In how rickets is diagnosed, blood tests and X-rays are often the main tools, with extra testing if the cause is not clear.
The doctor asks about symptoms, growth, diet, supplements, and time outdoors, since these can affect vitamin D and calcium levels. A family history and past health problems can also help show whether rickets may be nutritional, related to bowel or kidney disease, or less commonly inherited.
The exam looks for signs such as bowed legs, widened wrists or ankles, bone tenderness, delayed tooth changes, or trouble growing as expected. In babies and young children, the doctor may also check the skull, chest shape, muscle tone, and how the child is meeting movement milestones.
Blood tests usually check calcium, phosphate, alkaline phosphatase, and vitamin D levels. These results can strongly support the diagnosis of rickets and may also point to the underlying cause. Parathyroid hormone and kidney-related tests may be added when needed.
X-rays of the wrists, knees, or other growing bones can show classic changes where bone is forming abnormally. Doctors look for widening, fraying, and cupping near the growth plates, which are common imaging findings in rickets.
How is Rickets diagnosed?
Rickets is usually diagnosed with a mix of a physical exam, questions about growth, diet, and time in sunlight, and tests that look for weak or poorly mineralized bones. Doctors often use blood tests to check vitamin D, calcium, and other minerals, and they may order X-rays to look for changes in growing bones, especially if a child has bowed legs, bone pain, or delayed growth. If the usual tests do not give a clear answer, or if an inherited form is suspected, genetic testing may sometimes help confirm the cause.
Stages of Rickets
Rickets does not have defined progression stages. This is because it is usually described by how soft or weak the growing bones are, rather than by a set pattern of step-by-step decline over time. Doctors usually start with a conversation about symptoms such as bone pain, delayed growth, bowed legs, or the early symptoms of rickets, then examine the bones, muscles, and walking pattern. Blood tests and X-rays are often used to confirm the cause and to monitor improvement after treatment.
Outlook and prognosis
With prompt diagnosis and treatment, most children with rickets have an excellent outlook, with pain improving within weeks and bone healing over months. Growth and bone deformities may partially or completely correct in young children, but severe or long-standing disease can leave permanent bowing, short stature, dental problems, or pelvic deformity. Prognosis depends on the cause, because nutritional rickets usually responds very well to vitamin D, calcium, and diet changes, while genetic or kidney-related forms often require long-term specialist care and may be harder to fully reverse. If untreated, rickets can lead to fractures, delayed motor development, low calcium complications such as seizures or cardiomyopathy, and impaired adult bone health. Death from rickets is uncommon today when medical care is available, but severe untreated vitamin D deficiency can rarely be life-threatening because of profound hypocalcemia or heart complications. Lifelong outlook is generally good when the underlying cause is identified early and treatment is maintained.
Long-term effects
When rickets is treated early, many children go on to grow and move well. If it is severe, lasts a long time, or is not fully corrected, rickets can leave lasting changes in bone shape, growth, and joint comfort that may continue into adult life. The long-term picture is often better when the cause is found and treated promptly, but some effects can remain even after the active disease improves. In some children, early symptoms of rickets such as bowed legs or delayed growth are the first sign of changes that can persist over time.
Long-standing rickets can lead to bowed legs, knock knees, or changes in the chest, spine, or pelvis that do not fully straighten later on. These changes may be mild, but in some people they can affect posture, walking, or how clothes and shoes fit.
Poor bone mineralization during childhood can slow normal growth and lead to shorter adult height. The risk is higher when rickets starts early, is severe, or continues for a long time before treatment.
Some people living with rickets continue to have aching in the legs, back, or joints even after the vitamin or mineral problem has been corrected. This may be more noticeable after standing, walking, or other weight-bearing activity.
Changes in leg alignment can place extra stress on the hips, knees, and ankles over many years. Over time, daily routines may involve more stiffness, uneven shoe wear, or earlier joint wear than expected.
How is it to live with Rickets?
Living with rickets can mean bone pain, muscle weakness, tiredness, and trouble keeping up with everyday movement, so things like walking long distances, climbing stairs, standing for a while, or joining sports may feel harder than they should. In children, bowed legs, delayed growth, or frequent fractures can also affect confidence and independence, but with the right treatment, many improve and avoid long-term problems. For families and other caregivers, daily life may include extra medical visits, help with mobility and pain, and emotional support, yet having a clear diagnosis and treatment plan often makes day-to-day life feel much more manageable.
Treatment and drugs
Rickets is treated by correcting the cause, most often with vitamin D and calcium, and sometimes phosphate if levels are low. In many children, this means daily or weekly supplements, eating enough calcium-rich foods, and getting safe sunlight exposure when appropriate, while the doctor checks blood tests and bone healing over time. Doctors sometimes recommend a combination of lifestyle changes and drugs, especially when treatment for rickets caused by kidney problems, liver disease, or inherited forms needs more than standard vitamins. If bones have become very bent or painful, braces, physical therapy, or surgery may be needed, but many people improve once the missing nutrients are replaced and the underlying problem is treated.
Can you cure Rickets?
Rickets can often be treated very well, and some children are fully cured, especially when it is caused by not getting enough vitamin D or calcium. Treatment usually includes supplements, diet changes, and treating the underlying cause, which can help bones grow stronger and ease pain and weakness. If rickets is caused by a genetic condition or has already led to major bone bending, it may not be fully curable, but ongoing care can still help a lot.
Non-drug treatment
Rickets can affect everyday things like walking, standing for long periods, or joining in active play because soft, weak bones bend more easily. Alongside medicines, non-drug therapies for rickets focus on building bone strength, supporting movement, and helping prevent lasting bone changes. For many, treatment begins not at the pharmacy, but with food choices, safe sun exposure, and practical support at home and school. In children with more severe bone bending or trouble walking, rehabilitation or orthopedic care may also be part of treatment.
Eating enough calcium, phosphate, and protein helps give growing bones the raw materials they need to harden properly. This may mean more dairy foods or fortified alternatives, eggs, oily fish, and other nutrient-rich foods, depending on the cause of rickets.
Regular, sensible sunlight exposure can help the skin make vitamin D, which supports bone mineralization. The amount that helps varies with skin tone, season, latitude, clothing, and sunscreen use, so families often need tailored advice that balances bone health with sun safety.
A dietitian can help if rickets is linked to a very limited diet, food allergy, poor intake, or feeding difficulties. Some strategies can slip naturally into your routine—like adjusting meals, snacks, or fortified foods—so nutrition goals feel more manageable day to day.
Physical therapy can help children with rickets improve muscle strength, balance, and walking patterns when pain or weak bones have limited activity. This can matter when early symptoms of rickets include delayed walking, tiring easily, or trouble keeping up with play.
Your genes may have an impact on how drugs work for you
For many living with rickets, genes can matter because some inherited forms do not respond well to the usual treatment with vitamin D alone, so a child may keep having bowed legs, bone pain, or slow growth even when taking it as directed. In these cases, the body may have trouble activating vitamin D, moving phosphate into the blood, or keeping the right balance of minerals for strong bones, which can mean a different type of vitamin D, extra phosphate, or closer follow-up is needed. This is why doctors sometimes look for an inherited cause of rickets when standard treatment is not helping as expected, since the right treatment can depend on the exact reason the bones are not hardening normally.
Pharmacological treatments
Treatment for rickets is aimed at replacing what the body is missing and correcting the cause, so day-to-day symptoms like bone pain, delayed growth, or muscle weakness can gradually improve. Many people with rickets are treated with vitamin D and calcium, while others need more targeted medicines if the problem is tied to low phosphate levels or trouble activating vitamin D. Not everyone responds to the same medication in the same way. In children, doctors also monitor growth, blood tests, and bone healing while treatment is adjusted.
Cholecalciferol and ergocalciferol are common forms of vitamin D used when rickets is caused by low vitamin D. This is the main treatment for vitamin D deficiency rickets, and the dose may be given daily or as a larger supervised course depending on age and severity.
Calcium carbonate or calcium citrate may be added when calcium intake is low or blood calcium is reduced. For many living with rickets, calcium is used together with vitamin D because bones need both to harden properly.
Calcitriol or alfacalcidol may be used when the body cannot activate regular vitamin D well, such as in some kidney or liver problems. These medicines need closer monitoring because they can raise calcium levels too much if the dose is not adjusted carefully.
Oral phosphate supplements are used in forms of rickets caused by phosphate wasting, including some inherited types. In some cases, medicines are combined for better control, so phosphate is given along with calcitriol to support bone mineralization.
Genetic influences
Rickets is often linked to low vitamin D, calcium, or phosphate, but in some families it happens because of inherited gene changes. It’s natural to ask whether family history plays a role. Rare genetic causes of rickets can affect how the body absorbs or uses vitamin D, how the kidneys keep phosphate in balance, or how growing bones harden. These inherited forms may come to light when a child has bowed legs, bone pain, slow growth, or other early symptoms of rickets that do not improve as expected with standard supplements. Many children with rickets do not have a single genetic cause, so doctors also look at diet, sun exposure, kidney health, and other medical problems. If an inherited form of rickets is suspected, genetic testing and a careful family history can help guide treatment and show whether relatives may also be at risk.
Is Rickets genetic?
Genetics can be very important in rickets. While many cases are not inherited, some forms run in families because gene changes affect how the body handles vitamin D, phosphate, or bone mineralization.
Having a genetic risk is not necessarily a diagnosis
Genetic variants are a normal and common part of human biology. Most do not directly affect health and simply reflect natural human diversity. For many genes, having a variant associated with a condition points to a possible link rather than a certain diagnosis, especially when several genes and environmental factors are involved. In some cases, though, a single well-understood variant in a specific gene is enough to confirm the diagnosis.
Pharmacogenetics—how genetics influence drug effects
Treatment for rickets can differ a lot depending on why the bones are not getting what they need to harden. In many children with rickets caused by low vitamin D or low calcium, supplements work well, but inherited forms may not improve with standard vitamin D alone because the body may have trouble handling phosphate or turning vitamin D into its active form. Genetic testing can sometimes identify how your body handles these pathways, which helps doctors choose the right treatment, such as phosphate and active vitamin D, or in some inherited types, a targeted medicine like burosumab. This is one reason genetic testing for rickets treatment can be helpful: the usual treatment may help only a little in a genetic form of rickets, and in some cases it can raise the risk of side effects such as high calcium levels or kidney problems. Genetics is only one factor, but for many living with rickets, it can explain why one treatment plan works better than another and why regular blood and urine checks are often part of care.
Interactions with other conditions
Rickets can sometimes appear alongside other health problems, especially conditions that make it hard for the body to absorb or use vitamin D, calcium, or phosphate. This means children living with rickets may also have digestive disorders such as celiac disease or inflammatory bowel disease, kidney problems, or liver disease, because these can disrupt the balance the bones need to grow strong. Doctors call it a “comorbidity” when two conditions occur together. Some inherited conditions can also lead to rickets-like bone changes, and in those cases the bone symptoms are part of a broader genetic disorder rather than a stand-alone problem. Day to day, this can mean a child with rickets may still have bone pain, delayed growth, or bowed legs even after starting supplements if another illness is also affecting nutrient levels. Talk with your doctor about how your conditions may influence each other, especially if the early symptoms of rickets do not improve as expected.
How genes can cause diseases
Humans have more than 20,000 genes, each carrying out one or a few specific functions in the body. One gene instructs the body to digest lactose from milk, another tells the body how to build strong bones and another prevents the body's cells from beginning to multiply uncontrollably and developing into cancer. As all of these genes combined are the building instructions for our body, a defect in one of these genes can have severe health consequences.
Through decades of genetic research, we know the genetic code of any healthy/functional human gene. We have also identified that in certain positions on a gene, some individuals may have a different genetic letter from the one you have. We call these hotspots "Genetic Variations" or "Variants" in short. In many cases, studies have been able to show that having the genetic letter "G" in the position makes you healthy, but having the letter "A" in the same position disrupts the gene function and causes a disease. Genopedia allows you to view these variants in genes and summarizes all that we know from scientific research, which genetic letters (Genotype) have good or bad consequences on your health or on your traits.
What other conditions can cause similar symptoms to Rickets?
Yes. Bowed legs, bone pain, weak muscles, and slow growth can also happen with Blount disease, which affects the growth of the shin bone, with some rare inherited bone disorders such as brittle bone disease, and with long-term kidney problems that upset the body’s balance of calcium and other minerals. Because these can look alike at first, doctors often use a mix of an exam, blood tests, and X-rays to tell them apart.
History
Long before doctors understood the cause, families noticed some children were slow to sit, stand, or walk, and that their legs seemed to curve as they grew. What we now call rickets has been described for centuries, with signs that likely appeared in ancient skeletal remains and later in medical writings from Europe and beyond.
By the 1600s and 1700s, physicians had begun describing the condition more clearly, especially in growing children with soft, weak bones, bone pain, and changes in the shape of the legs, chest, or wrists. Rickets became especially common during the Industrial Revolution, when many children in crowded cities spent little time in sunlight and diets were often poor. For many families, this could mean a child who tired easily, had trouble keeping up at play, or seemed delayed in reaching physical milestones.
In the late 1800s and early 1900s, researchers started linking rickets to poor nutrition and lack of sun exposure. That led to some of the first effective treatments, including cod liver oil and more time outdoors. Later, scientists identified the role of vitamin D and learned that calcium and phosphate also matter for healthy bone growth. These discoveries changed everyday care in a practical way: preventing rickets became possible for many children, not just treating it after bones had already softened.
As food fortification and better nutrition spread, rickets became less common in many parts of the United States and Europe. In recent decades, awareness has grown that rickets has not disappeared. It can still affect infants, children, and sometimes adults with related bone-softening problems, especially when diet is limited, sun exposure is low, absorption problems are present, or there is an underlying medical or genetic cause.
The history of rickets is a good example of how medicine often moves from careful observation to prevention. Early symptoms of rickets were once easy to miss or explain away as “late blooming,” but over time doctors learned to connect those day-to-day signs with bone health. Today, that history helps guide screening, nutrition advice, and treatment, and it also reminds us that rickets can have more than one cause even if the outward signs look similar.
