Celiac artery compression syndrome is a rare condition where pressure on the celiac artery limits blood flow to the upper belly. People with celiac artery compression syndrome often feel upper abdominal pain after meals and may have nausea or unintentional weight loss. Symptoms can come and go and may persist for months or years if untreated. It is usually found in young to middle-aged adults, and early symptoms of celiac artery compression syndrome may be vague. Treatment often involves minimally invasive surgery to release the pressure, and the outlook is generally good with low mortality.
Overview
Celiac artery compression syndromeSymptoms
Celiac artery compression syndrome causes upper belly pain, often after meals, that may improve when leaning forward. Early symptoms include nausea, bloating, early fullness, and unintentional weight loss; some avoid eating. Doctors may note a whooshing belly sound or tenderness.
Outlook and prognosis
Most people with celiac artery compression syndrome improve significantly once the artery pressure is relieved, often through minimally invasive surgery. Energy, weight, and meal tolerance usually rebound over weeks to months. Ongoing follow-up helps address scar tissue, symptom return, or nutrition gaps.
Causes and risk factors
Celiac artery compression syndrome results from congenital positioning of the median arcuate ligament, which compresses the celiac artery and nerves. Risks are higher in women and thin young adults; exhalation and rapid weight loss may worsen compression; genetic influence minimal.
Genetic influences
Genetics play a minor role in Celiac artery compression syndrome. It’s usually linked to anatomy—how the ligament and artery are positioned—rather than inherited variants. Family clustering is uncommon, and routine genetic testing isn’t recommended.
Diagnosis
Celiac artery compression syndrome is diagnosed by matching symptoms with vascular imaging. Doctors often start with Doppler ultrasound and confirm with CT or MR angiography. Imaging also helps rule out other, more common causes of abdominal pain and weight loss.
Treatment and drugs
Treatment for celiac artery compression syndrome focuses on relieving the artery squeeze and easing symptoms. Many feel better after minimally invasive surgery to release the ligament; some need artery widening (angioplasty/stent) if narrowing persists. Nutrition support and pain management help recovery.
Symptoms
Celiac artery compression syndrome can cause upper belly pain, especially after meals, that can make eating feel stressful. Early symptoms of Celiac artery compression syndrome may be mild and come and go, often tied to eating or activity. Symptoms vary from person to person and can change over time. Over weeks or months, some people reduce portion sizes or avoid meals to dodge the pain, which can lead to weight loss.
Upper abdominal pain often starts soon after eating and can last for hours. It may ease with rest or leaning forward and can range from dull to sharp.
Feeling sick to your stomach can accompany the pain, and some vomit during flares. This can make you hesitant to eat normal meals. People with Celiac artery compression syndrome often notice this after heavier or fatty foods.
You may feel full after just a few bites, often with bloating or pressure under the ribs. Clinicians call this early satiety, which means feeling full sooner than expected. It can lead to smaller portions and skipped meals.
Eating less to avoid pain can lead to unintentional weight loss over weeks or months. Clothes may start to fit looser without trying. In Celiac artery compression syndrome, this often reflects food fear around meals.
How people usually first notice Celiac artery compression syndrome?
Many people first notice celiac artery compression syndrome when eating starts to feel like a trigger—cramping upper belly pain begins shortly after meals, sometimes with nausea, bloating, or diarrhea, and eases when they stop eating or lose weight without trying. Some describe a gnawing pain just below the breastbone that worsens with deep breathing or exercise and improves when leaning forward, which prompts a doctor visit. Clinicians may then pick up clues like an audible abdominal “bruit” (whooshing sound) or abnormal blood flow on an ultrasound done for persistent post-meal pain.
Types of Celiac artery compression syndrome
Celiac artery compression syndrome affects people differently depending on how tightly the artery is squeezed and which nearby nerves are irritated. Daily life often makes the differences between symptom types clearer. Some feel symptoms mainly after meals, while others notice them during exercise or with deep breathing. Clinicians often describe them in these categories:
Post‑meal symptoms
Pain and cramping start shortly after eating, often upper‑middle or left‑upper belly. Nausea, early fullness, or unintentional weight loss can follow as people eat less to avoid pain. Bloating or loose stools may appear after larger meals.
Exercise‑triggered pain
Belly pain or side‑stitch discomfort shows up during running, cycling, or heavy exertion. Symptoms ease with rest or when leaning forward. Some notice brief lightheadedness if pain is intense.
Position‑related flares
Pain worsens when standing tall or inhaling deeply and eases when bending forward or curling onto the side. People may unconsciously hunch after meals to reduce symptoms. Nighttime discomfort can improve with a slight forward‑leaning posture.
Nerve‑predominant pattern
Burning or stabbing pain radiates to the back or flanks, suggesting nearby nerve irritation. Nausea and food fear may be less prominent than the sharp pain. Even within the same type, intensity can range from mild to severe.
Vascular‑predominant pattern
Cramping pain with a "hungry gut" feel points to reduced blood flow during digestion. Weight loss and food avoidance are more common in this pattern. Some notice a whooshing abdominal sound a clinician may detect with a stethoscope.
Mixed pattern
Features of both nerve and blood‑flow issues appear together and shift day to day. One type may be strong for a while, then fade as another emerges. This variability can make early symptoms of celiac artery compression syndrome hard to recognize.
What genetics can tell you about symptoms
Some people with celiac artery compression syndrome who have variants affecting connective tissue strength or ligament thickness may feel post‑meal upper belly pain, nausea, or unintentional weight loss. These changes can tighten the median arcuate ligament, increasing artery and nerve compression.
Causes and risk factors
The main cause of celiac artery compression syndrome is a tight band of tissue under the diaphragm that presses on the celiac artery and nearby nerves. This pressure depends on your anatomy and often increases when you breathe out. No single gene is known to cause it, but the body anatomy that allows the squeeze is often present from birth. Risk factors for celiac artery compression syndrome include being female and having a thin body build, and less fat padding in the upper belly can reduce cushioning. Having risk factors doesn’t mean you’ll definitely develop the condition.
Environmental and biological risk factors
For most people, the likelihood of celiac artery compression syndrome comes down to body structure and how the diaphragm moves with breathing. Researchers are still exploring how outside influences interact with our inner biology. Several biological features—mainly the position of a small ligament, the artery’s starting point, and nearby nerve tissue—can raise the chance of compression. Knowing these helps explain why early symptoms of celiac artery compression syndrome appear in some people while others never have issues.
When the thin band beneath the diaphragm sits lower than usual, it can press on the celiac artery. This congenital setup raises the chance of celiac artery compression syndrome.
If the celiac artery starts higher on the main vessel, it meets the ligament sooner. That close meeting point increases the odds of compression.
As the diaphragm lifts during exhalation, nearby tissues can push the artery. This can tighten an existing narrowing in celiac artery compression syndrome.
A thicker or more forward nerve bundle near the artery can add pressure. This biological layout may heighten sensitivity in the area.
Genetic risk factors
For Celiac artery compression syndrome, genetics take a back seat to anatomy you’re born with. No specific gene is known to cause it, and most cases are not inherited. Some risk factors are inherited through our genes, but for this condition the main influences are congenital positions of the ligament and artery rather than a single gene change.
No single-gene cause: No gene has been proven to cause Celiac artery compression syndrome. Most people with the condition have normal genetic testing.
Congenital ligament position: A lower-than-usual position of the median arcuate ligament can press on the celiac artery. This arrangement is present from birth and is not known to follow a clear inheritance pattern.
High celiac takeoff: A higher origin of the celiac artery increases the chance of contact with the ligament. This anatomic variant is present from birth rather than driven by a single gene change.
Arterial shape variants: Differences in the angle or course where the celiac artery branches from the aorta can narrow the space. These developmental patterns are congenital traits, not tied to a specific gene.
Connective tissue disorders: People with inherited connective tissue conditions, such as Ehlers-Danlos or Marfan syndrome, sometimes have vascular compression syndromes. Evidence for a direct link to Celiac artery compression syndrome is limited, and most with these conditions never develop it.
Familial cases rare: A few families have more than one member with Celiac artery compression syndrome. No shared mutation or predictable inheritance pattern has been identified.
Symptoms not predicted: Genes and anatomy cannot reliably forecast who will develop pain or other early symptoms of Celiac artery compression syndrome. Severity and timing vary even when scans look similar.
Lifestyle risk factors
Celiac artery compression syndrome is driven by an anatomic compression rather than your habits, but daily choices can influence symptoms and flares. Lifestyle changes do not cause the condition; they can shape how often pain, nausea, or post-meal discomfort occur. Below are practical ways how lifestyle affects Celiac artery compression syndrome, focusing on real symptom triggers and relief patterns.
Large meals sharply increase blood flow needs to the stomach and can trigger pain, nausea, or early fullness. Smaller, more frequent meals may lessen postprandial symptoms and improve tolerance.
High‑fat meals demand prolonged splanchnic blood flow, which can intensify ischemic-type pain. Choosing lower‑fat options may reduce meal‑related flares.
Eating quickly can cause larger, faster gastric filling and higher splanchnic demand. Slowing the pace of meals may reduce postprandial pain and cramping.
Significant weight loss can reduce the fat pad around the celiac artery, sometimes worsening compression-related symptoms. Stabilizing weight under medical guidance may help symptom control.
Risk prevention
You can’t fully prevent this condition because it stems from the way the ligament and artery are positioned. Celiac artery compression syndrome prevention focuses on spotting symptoms early, protecting nutrition, easing triggers, and staying on top of follow-up care. Prevention is about lowering risk, not eliminating it completely. If you notice early symptoms of celiac artery compression syndrome—like upper abdominal pain after meals, nausea, or unexplained weight loss—prompt evaluation can help head off complications.
Watch for post-meal upper abdominal pain, nausea, or unintended weight loss and seek medical review promptly. Talk to your doctor about which preventive steps are right for you.
Smaller, more frequent, lower-fat meals may lessen post-meal blood-flow demand and discomfort. Staying upright after eating and sipping fluids can also help.
Avoid rapid weight loss, which can reduce the natural cushioning around the artery and potentially worsen celiac artery compression syndrome symptoms. Aim for steady, adequate nutrition with support from a dietitian if needed.
Choose gentle to moderate activities and pace exertion if intense exercise brings on symptoms. Avoid motions that strongly strain or compress the upper abdomen, and build back slowly if you’ve been unwell.
Transmission
Celiac artery compression syndrome is not contagious and cannot be passed from person to person. It happens when a band of tissue beneath the diaphragm presses on the celiac artery, a difference in anatomy that’s usually present from birth. There is no proven genetic transmission of celiac artery compression syndrome; most cases do not show a clear inheritance pattern, though the anatomy may occasionally run in families. In short, you can’t “catch” it, and how celiac artery compression syndrome is inherited is generally not a concern for most families.
When to test your genes
Consider genetic testing if close relatives have unexplained early vascular problems, connective tissue disorders (like Marfan or Ehlers-Danlos), or if you have recurring post-meal abdominal pain with weight loss despite normal GI tests. While Celiac artery compression syndrome is mechanical, genes can influence vessel structure and collagen. Results can guide imaging urgency, surgical planning, and family screening.
Diagnosis
Early clues to Celiac artery compression syndrome often show up as post-meal upper belly pain, feeling full quickly, and gradual weight loss that leads people to seek answers. It’s natural to worry when symptoms don’t have a clear explanation. Understanding how Celiac artery compression syndrome is diagnosed can help you know what to expect. Most people go through a step-by-step evaluation to confirm the artery compression and rule out more common causes of similar symptoms.
Your clinician asks about timing of pain with meals, weight changes, and how symptoms affect eating and activity. The physical exam is often normal, but the pattern of symptoms helps guide next steps.
Blood tests and stool checks can look for infection, inflammation, anemia, or pancreas and liver problems. These results help rule out common causes of abdominal pain and weight loss.
A special ultrasound measures blood-flow speed in the celiac artery. Higher speeds, especially when breathing out, suggest a narrowing that eases when you breathe in.
A contrast CT scan shows the shape of the celiac artery and nearby structures. It can reveal a characteristic pinch with a downstream widening and also check for other abdominal causes of pain.
Stages of Celiac artery compression syndrome
Celiac artery compression syndrome does not have defined progression stages. Symptoms often ebb and flow rather than steadily worsening, because the compression and nearby nerve irritation can vary with breathing and body position. Doctors usually start with a conversation about your symptoms and weight changes, then use imaging—such as ultrasound of blood flow or a CT/MR angiogram—to look for narrowing that changes with breathing. Early symptoms of celiac artery compression syndrome can overlap with common stomach issues, so tests are used to rule out other causes and to guide treatment planning.
Outlook and prognosis
Looking ahead can feel daunting, but most people with Celiac artery compression syndrome (also called median arcuate ligament syndrome) improve once the compression is relieved, either through surgery to release the ligament or, less often, with closely monitored non-surgical care. The outlook is not the same for everyone, but pain after meals, unintentional weight loss, and food avoidance often ease within weeks to months after successful treatment, allowing people to return to regular eating and daily activities. In clinical follow-up studies, a majority report meaningful symptom relief, though a smaller group continue to have intermittent discomfort or need additional procedures if the artery narrows again.
Prognosis refers to how a condition tends to change or stabilize over time. Early symptoms of Celiac artery compression syndrome—like post-meal cramping, bloating, and feeling full quickly—tend to drive weight loss and low energy, so timely diagnosis and treatment matter for quality of life and nutritional recovery. Serious complications such as bowel ischemia are uncommon, and the condition is rarely life-threatening when recognized and managed; reported deaths are exceptionally rare and usually linked to delayed diagnosis or other medical problems.
Over time, most people with Celiac artery compression syndrome regain weight and resume exercise, travel, and work, though endurance can take a little longer to return as eating patterns normalize. Some people notice significant relief after the first procedure, while for others, persistent symptoms prompt evaluation for nerve-related pain, reflux, gallbladder issues, or a redo surgery or stent if narrowing recurs. In medical terms, the long-term outlook is often shaped by both genetics and lifestyle, but for this condition, anatomy and technique of the initial release or vascular repair play a larger role.
Talk with your doctor about what your personal outlook might look like. Knowing what to expect can ease some of the worry, and setting shared goals—comfortable meals, steady weight, and activity milestones—helps track progress in the months after treatment. Keep regular appointments—small adjustments can improve long-term health, including nutrition plans, pain strategies, and imaging if symptoms return.
Long-term effects
Celiac artery compression syndrome can affect day-to-day life by making meals uncomfortable and activity harder to enjoy. Long-term effects vary widely and can shift over time. Some people improve after treatment, while others continue to notice digestive or pain symptoms that wax and wane. Early symptoms of celiac artery compression syndrome can look like common stomach issues, which sometimes delays diagnosis.
Cramping or stabbing upper‑abdominal pain may continue after eating, especially larger meals. This can lead to smaller portions and slower eating.
Ongoing pain and nausea can reduce calorie intake over time. Some develop mild malnutrition or vitamin deficiencies if eating remains limited.
Worry about pain may cause people to skip meals or avoid certain foods. Over months, this can narrow the diet and affect social life around eating.
Long-standing nausea and early fullness can linger even when pain eases. These sensations may come and go and often worsen after exertion or stress.
How is it to live with Celiac artery compression syndrome?
Daily life with celiac artery compression syndrome can swing between stretches of feeling fine and sudden bouts of upper abdominal pain after meals, early fullness, nausea, or unintended weight loss that make eating feel like work instead of comfort. People often adapt by changing meal size and timing, limiting intense exercise that triggers pain, and planning around medical visits or imaging. This unpredictability can affect work, school, and social plans, and loved ones may worry or adjust cooking and routines to help. With a clear diagnosis, nutrition support, symptom tracking, and, when appropriate, surgical treatment, many regain control and see daily life become far more manageable.
Treatment and drugs
Treatment for celiac artery compression syndrome focuses on relieving the pressure on the artery and improving blood flow so eating becomes comfortable again. For many, the main treatment is surgery to release the fibrous band (the median arcuate ligament) that’s compressing the artery; this can often be done through small incisions (laparoscopic or robotic), and some people also need the celiac artery widened with a stent if it stays narrowed. Pain relievers and nutrition support may help in the short term, but they don’t fix the compression itself. Finding the right therapy can take some time, and your surgeon may coordinate with a vascular specialist to plan the best approach for you. After treatment, follow-up usually includes symptom checks, weight and nutrition review, and imaging to confirm the artery stays open.
Non-drug treatment
People with celiac artery compression syndrome often focus on ways to eat, move, and plan care that lessen post-meal pain and support weight and energy. Because early symptoms of celiac artery compression syndrome can look like many other stomach issues, teams may begin with nutrition support and careful follow-up while confirming the diagnosis. Non-drug treatments often lay the foundation for recovery, and procedures or surgery are added when needed. Plans are tailored—some feel better with simple steps, while others need an operation to fully relieve the artery pressure.
Surgeons free the tight band pressing on the celiac artery and nearby nerves through small cuts. This minimally invasive approach can ease post-meal pain and help with weight regain.
A larger incision may be chosen when anatomy is complex or prior surgery makes a keyhole approach difficult. It allows the surgeon to address scar tissue and, if needed, repair the artery during the same operation.
During release surgery, the irritated nerve tissue around the celiac artery can be trimmed. This may reduce pain sensitivity and improve eating tolerance.
If the artery stays narrow after ligament release, a stent can help keep it open. Stenting does not fix external compression by itself, so it is usually an add‑on rather than the first step.
Your genes may have an impact on how drugs work for you
Medications used for celiac artery compression syndrome—like pain relievers, anti-nausea drugs, and agents affecting blood flow—can work differently depending on your genes, which influence drug breakdown and sensitivity. Pharmacogenetic differences may change dose needs and side‑effect risk, so personalized prescribing helps.
Pharmacological treatments
For many, day-to-day life with Celiac artery compression syndrome means working around pain after meals, nausea, or trouble keeping weight up while planning for procedures that address the cause. Drugs that target symptoms directly are called symptomatic treatments. Medicines can help you eat, stay hydrated, and manage discomfort, especially when early symptoms of Celiac artery compression syndrome start to interfere with routine. Your care team will tailor choices to your goals, other conditions, and any upcoming surgery.
Acetaminophen (paracetamol) can ease mild pain, and short courses of NSAIDs like ibuprofen or naproxen may help if your stomach tolerates them. Strong opioids are usually avoided or kept brief because they can worsen constipation and dull gut motility.
Low-dose amitriptyline, duloxetine, gabapentin, or pregabalin can calm nerve-driven upper‑abdominal pain. Dosing may be increased or lowered gradually to balance relief with side effects like sleepiness or dry mouth.
Ondansetron or prochlorperazine can reduce waves of nausea and help you keep meals down. Metoclopramide may help both nausea and slow stomach emptying but is typically limited to short courses to avoid movement-related side effects.
Proton pump inhibitors such as omeprazole or pantoprazole, or H2 blockers like famotidine, can ease reflux and upper‑stomach irritation that flare with frequent small meals. This can make post‑meal discomfort more manageable while other treatments are planned.
Genetic influences
People often ask whether celiac artery compression syndrome is genetic. It’s natural to ask whether family history plays a role. So far, there’s no strong evidence that it follows a clear inherited pattern; for most, it stems from how the diaphragm’s ligament sits over the celiac artery—an anatomic setup present from early development rather than a single “faulty” gene. Some families share body build or connective tissue traits, and rare heritable conditions such as Ehlers-Danlos syndrome can influence ligament or vessel structure, which might make compression more likely, but this link isn’t well proven. Because of this, DNA testing isn’t routinely used for celiac artery compression syndrome, and having a relative with the condition doesn’t reliably predict who else will be affected. If several relatives have similar vascular compression symptoms or you live with a known connective tissue disorder, talk with your clinician about whether a genetics referral makes sense for you.
Is Celiac artery compression syndrome genetic?
Genetics play a minor role in Celiac artery compression syndrome. It’s usually linked to anatomy—how the ligament and artery are positioned—rather than inherited variants. Family clustering is uncommon, and routine genetic testing isn’t recommended.
Pharmacogenetics—how genetics influence drug effects
While surgery is the main treatment for celiac artery compression syndrome, many people still receive medicines before and after procedures—for pain, nausea, and sometimes blood thinners—so how your body processes drugs matters. Small genetic differences in the enzymes that break down medicines can change how well these drugs work and the chance of side effects. Pain relievers that rely on liver conversion, such as codeine or tramadol, may be too weak in some or too strong in others; if that happens, your team can switch to alternatives or tailor the dose. Anti-nausea medicines like ondansetron and some sedatives used for anesthesia may also be cleared faster or slower depending on your genes, which can affect how well they work after surgery. Genetic testing can sometimes identify how your body handles specific pain medicines, anti-nausea drugs, or blood thinners, helping your team tailor choices. Decisions about medications used for celiac artery compression syndrome still consider your symptoms, anatomy, other health conditions, and drug interactions—genetics adds one more useful piece to the picture.
Interactions with other conditions
People with celiac artery compression syndrome often find their belly pain and nausea seem to overlap with other gut problems, which can make day-to-day decisions about food and activity tricky. Doctors call it a “comorbidity” when two conditions occur together. Because early symptoms of celiac artery compression syndrome can mimic gallbladder disease, peptic ulcers, or irritable bowel syndrome, many are first assessed for those issues, and having them at the same time can blur the picture and delay the right treatment. Celiac artery compression syndrome can also appear alongside other “compression” conditions—such as nutcracker syndrome, May–Thurner syndrome, or superior mesenteric artery syndrome—and with connective tissue differences like hypermobility, which may partly explain why some people report symptoms in more than one area. In older adults or those with vascular disease, reduced blood flow from artery plaque plus compression may intensify post‑meal pain and unintended weight loss, while conditions that cause significant weight loss can, in turn, make the compression symptoms more noticeable. Some also live with dysautonomia or POTS, and the combination of pain, reduced appetite, and lightheadedness can compound fatigue and limit daily activities. Interactions can look very different from person to person, so coordinated care that checks for overlapping digestive, vascular, and autonomic issues is often the most effective path forward.
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.
History
Throughout history, people have described sudden upper abdominal pain after meals that eased only with rest or leaning forward, long before anyone could see inside the abdomen. Families and communities once noticed patterns—relatives who ate small, frequent meals to avoid pain, or teens who lost weight during sports season when appetite and activity rose. These lived details echo what we now recognize as Celiac artery compression syndrome.
First described in the medical literature as “celiac axis compression” in the mid-20th century, it was initially pieced together from symptoms and surgical findings rather than scans. Early surgeons noticed a tough band of tissue near the diaphragm—the median arcuate ligament—pressing on the celiac artery and sometimes on the surrounding nerve network. When that pressure was relieved during surgery, many reported that post‑meal pain and weight loss improved, which helped clinicians link anatomy to symptoms.
From these first observations, technology changed the story. As medical science evolved, angiography and later Doppler ultrasound and CT or MR angiography showed how the artery could narrow during exhalation when the diaphragm rises, then open a bit on inhalation. This breathing effect helped explain why pain could wax and wane and why some people felt worse while standing upright or after exercise. It also showed that compression alone was common on imaging, but only a subset had the full symptom pattern—an early clue that blood flow changes, nerve irritation, and individual differences all play a role.
Over time, descriptions became more precise. Reports distinguished classic features—post‑meal upper abdominal pain, early fullness, nausea, and unintentional weight loss—from other causes of similar symptoms. Clinicians also recognized variability: some people had prominent pain with minimal weight change, while others mainly noticed food fear and reduced intake. Not every early description was complete, yet together they built the foundation of today’s knowledge.
With each decade, the approach to diagnosis and treatment matured. Imaging protocols began including breathing instructions to capture dynamic changes. Surgeons refined techniques to release the ligament and free the artery, sometimes adding methods to improve blood flow if needed. Follow‑up studies documented which features predicted better outcomes, such as a consistent meal‑related pain pattern and evidence of significant flow limitation on testing.
In recent decades, awareness has grown that Celiac artery compression syndrome is both anatomical and functional. Pressure from the ligament can narrow the artery like a dimmer switch on blood flow, while irritation of nearby nerves may amplify pain signals. Understanding this mix helps explain why some people improve with surgery and careful rehabilitation, and why others need a broader plan that addresses pain pathways, nutrition, and gradual return to activity. Each stage in history has added to the picture we have today, shaping a more balanced, patient‑centered view of this condition.
