A Hidden Cause of Chronic Abdominal Pain
If you live with hypermobility and ongoing abdominal pain, you may already know how exhausting it is to keep searching for answers and not finding any that fully make sense.
Some people live with severe abdominal pain for years. Eating becomes something they start to fear. Test after test comes back “normal,” yet the symptoms are very real.
In some of these cases, the missing piece turns out to be something called Median Arcuate Ligament Syndrome (MALS).
This is not the most common cause of abdominal pain, but for some people, it can change everything once it is identified.
What is the Median Arcuate Ligament?
The median arcuate ligament is a fibrous band that forms part of the diaphragm. It sits over the aorta and usually passes just above an important artery called the celiac artery, which supplies blood to your stomach, liver, and other digestive organs.
In some people, this ligament sits slightly lower or is tighter than usual. When that happens, it can compress the artery and nearby nerve structures.
This compression is what we call MALS.
Why this can matter more in hypermobility
If you have hypermobility, your connective tissue behaves differently. That can influence how structures like the diaphragm, ligaments, and blood vessels are positioned and how they move.
In hypermobility, the diaphragm can sit or move differently, and the tension through this area may change. Because the ligament is part of this system, that can increase the likelihood of compression on the artery and surrounding nerves.
In people with hypermobility or EDS, this may:
Change how the ligament interacts with the artery
Increase sensitivity of the surrounding nerves
Make symptoms feel more intense or harder to interpret
At the same time, many symptoms overlap with other conditions, which is why this can easily be missed.
What might this feel like?
You might notice things like:
Deep, severe pain in the upper abdomen, often after eating
Nausea or even vomiting
Bloating or discomfort that does not match what you’ve eaten
Eating less because it simply feels too painful
Weight loss or low energy over time
For some people, the intensity of the pain feels out of proportion to what tests initially show.
If this is sounding familiar, it does not mean this is definitely the cause, but it may be something worth looking into.
What is it often mistaken for?
One of the reasons MALS is missed is because it can look like many other conditions.
People are often initially told they may have:
Irritable bowel syndrome (IBS)
Acid reflux or gastritis
Functional abdominal pain
Gallbladder issues
Anxiety-related digestive symptoms
In some cases, people are told they have slowed stomach emptying (gastroparesis) or general gut dysmotility, without a clear reason why.
In hypermobility, symptoms are often attributed to general “nervous system sensitivity” or gut dysfunction, which can be true, but not always the full picture.
MALS tends to stand out when pain is severe, persistent, and closely linked to eating, especially when standard treatments are not helping.
Is there anything you can track yourself?
You cannot diagnose MALS on your own, but certain patterns can point toward it and are worth paying attention to.
What matters is not just what you feel, but the consistency of the pattern over time.
Patterns more suggestive of MALS include:
Pain that reliably worsens after eating (often within minutes, but the key is a consistent link to food)
A tendency to avoid food because you expect pain
Relief when eating smaller portions compared to larger meals
Pain located deep in the upper abdomen rather than shifting around
Symptoms persisting despite normal gastrointestinal tests
Patterns that are less specific and may point toward other causes:
Pain that is highly variable day to day without a clear trigger
Symptoms strongly linked to stress alone without a consistent food pattern
Lower abdominal or more widespread digestive discomfort
That said, in hypermobility, symptoms are often layered. A more variable pattern does not necessarily rule this out, but may suggest that more than one process is happening at the same time.
Additional clues that can support the picture:
Changes with posture or breathing. Because the diaphragm is involved, some people notice the pain worsens with deep breathing, or that certain positions slightly ease or aggravate it
Some people notice they change how they breathe when the pain starts, or feel unable to take a full, comfortable breath
Subtle relief with position changes, such as leaning forward
A sense that something feels “mechanical” or compressive rather than purely digestive
You are not looking for a single symptom, but a repeatable pattern.
If you start noticing a strong and consistent connection between eating and pain, especially when other tests have been normal, that is a reasonable point to bring this up with a specialist.
Tracking this clearly can make a meaningful difference in how quickly and accurately your case is understood.
Why diagnosis can take time
MALS is not always straightforward to diagnose. Many people go through multiple evaluations before it is considered.
Assessment may include:
Doppler ultrasound to look at blood flow changes with breathing
CT or MR angiography to see whether the artery is being compressed
Clinical evaluation of your symptom pattern
One important point: some people have compression on imaging and no symptoms at all. So the diagnosis is never based on a scan alone. Your experience matters.
What can be done?
Management of MALS is not always a single-path decision. While surgery is the main treatment for relieving the compression itself, many people benefit from a broader, more supportive approach, especially in the context of hypermobility.
Can MALS be managed without surgery?
For some people, yes. Especially when symptoms fluctuate, when surgery is not immediately appropriate, or while waiting for further evaluation.
In hypermobility, MALS rarely exists in isolation. This means management often focuses on reducing overall load on the system, not just one structure.
This may include:
1. Breathing and physical strategies
Because the ligament is part of the diaphragm, how you breathe and how your body is positioned can influence symptoms. Some people notice that certain postures or more supported, controlled breathing patterns reduce discomfort, even slightly.
2. Nutrition and symptom support
When eating is painful, the focus shifts from only what you eat to how you eat:
Smaller, more frequent meals
Adjusting food texture (for some, softer or more liquid meals are easier to tolerate)
Supporting adequate nutrition if intake has been reduced
3. Supporting the wider system
In people with hypermobility, symptoms are often influenced by multiple systems at once. Supporting areas such as:
Autonomic function (for example, symptoms consistent with POTS)
Mast cell-related symptoms
Gut motility
can change how pain is experienced, even if the compression itself is still present.
For some people, these approaches are enough to improve quality of life. For others, they become an important foundation before or after surgical treatment.
Surgical treatment
The main treatment for MALS, when clearly indicated, is surgery to release the ligament and reduce the pressure on the artery and surrounding nerves.
For some people, this can be life-changing.
Some individuals who have lived with pain for years, without clear answers, experience significant relief after surgery. They are able to eat more comfortably and regain energy.
It is also important to understand that this surgery addresses the compression itself. It does not change underlying connective tissue differences or nervous system sensitivity, which may still need support.
Outcomes do vary, and not everyone has complete resolution, but for the right person, this can be a significant turning point.
Why awareness matters
With hypermobility, pain is often complex and multi-layered. It can involve joints, soft tissue, the nervous system, and sometimes vascular or structural factors like this.
Conditions like MALS are often overlooked simply because they are not commonly discussed.
The more awareness there is:
The faster people can be directed toward appropriate investigations
The less time is spent feeling dismissed or confused
The more precise the support can become
If something in your body does not feel right, it is reasonable to keep asking questions.
Final thoughts
This is not the most common explanation for abdominal pain. But it is one that can be missed, especially in people with hypermobility.
For some, understanding this condition becomes the moment where things finally start to make sense.And for a smaller group, it can be the step that leads to real, lasting relief.
If you are navigating hypermobility and unexplained abdominal pain, there may still be answers worth exploring.
At ParaMotion, we support hypermobile and neurodivergent individuals in understanding the difference between nerve sensitivity, tissue response, and nervous system overload.
If you are ready to make sense of your symptoms and build a more responsive approach to your body, this is where that work begins.
