The median arcuate ligament (MAL) is a band of tissue that sits in the area where the chest and abdomen meet. Its job is to create a passageway for the aorta, the body's major blood vessel. Normally, this ligament sits across the aorta. Crucially, the celiac artery, which supplies blood to the stomach, intestines, and liver, runs right below the aorta's arch.
Sometimes, the median arcuate ligament can put pressure on the celiac artery. This is called median arcuate ligament syndrome (MALS). It can affect anyone, even young children. MALS is also known as celiac axis syndrome or Dunbar syndrome.
Experiencing pain in your stomach after eating or exercising could be a sign of MALS (likely meaning Microvascular Abdominal Syndrome, although more specific diagnosis is needed). Here are some common symptoms to be aware of:
Stomach pain: This pain often occurs after eating or exercising. The pain might feel better if you lean forward, lean back, or stand while eating. This is a key indicator, as the position affects the pain.
Food avoidance: The pain can be so uncomfortable that you might start to avoid eating certain foods. This avoidance can lead to significant weight loss.
Weight loss: If you're losing weight without trying to, it could be related to the pain and fear of eating.
Bloating: Feeling full or swollen in your stomach is another common symptom.
Loose stools (diarrhea): Frequent bowel movements that are looser than usual are also possible.
Nausea and vomiting: Feeling sick to your stomach and vomiting can be part of the experience.
Important Note: These are just some possible symptoms. If you're experiencing these, it's essential to talk to a doctor. They can properly diagnose the cause and recommend the best course of action. A medical professional can distinguish MALS from other potential conditions that share similar symptoms. Don't try to self-diagnose.
Stomach pain can have many reasons. If your stomach pain persists even after trying home remedies, it's important to see a doctor. A doctor will need to examine you thoroughly and run tests to figure out the exact cause.
If your stomach pain is severe and getting worse with movement, call your doctor right away. Also, seek immediate medical attention if your stomach pain is accompanied by any of these:
Sometimes, pain in your upper stomach can feel similar to chest pain. Chest pain can sometimes be a sign of a heart attack. Call 911 or emergency services immediately if you have chest or upper stomach pain, especially if you also experience any of these symptoms:
The reason why someone gets median arcuate ligament syndrome (MALS) isn't fully understood.
Understanding Median Arcuate Ligament Syndrome (MALS) is tricky because we don't fully know what causes it. This means the things that might raise your risk aren't completely clear. However, we do know that MALS is more often found in adults than children, and more often in women than men.
Interestingly, MALS has been seen in identical twins, suggesting a possible link to genetics. This means that if someone in your family has it, you might be more likely to develop it.
In some cases, people have developed MALS after having surgery on their pancreas or after a significant injury to their upper stomach area. This suggests that these procedures or injuries might somehow increase the risk of MALS. So, if you've had either of these experiences, you might want to be aware of the symptoms of MALS.
Median arcuate ligament syndrome (MALS) is diagnosed through a combination of physical examination, questions about symptoms, and various tests. A doctor will listen to your stomach with a stethoscope. Sometimes, a whooshing sound (called a bruit) might be heard, suggesting a narrowed blood vessel.
Because many different conditions can cause stomach pain, several tests are often needed to pinpoint the exact cause and rule out other possibilities.
Diagnosing MALS may involve these tests:
Blood tests: These tests check for problems with your liver, pancreas, kidneys, and other organs. A complete blood count (CBC) measures your red and white blood cell levels. A high white blood cell count could indicate an infection.
Upper endoscopy (EGD): A thin, flexible tube with a camera on the end is passed down your throat (after numbing medication). This allows the doctor to see the esophagus, stomach, and the beginning of your small intestine. Small tissue samples (biopsies) may be taken for further lab analysis.
Magnetic Resonance Imaging (MRI): An MRI uses magnets and radio waves to create detailed images of the area of concern. Sometimes, a special dye (contrast) is injected through a vein (IV). This dye helps show how blood flows through the arteries. This is called a magnetic resonance angiogram (MRA).
Abdominal Computed Tomography (CT) scan: A CT scan uses X-rays to create cross-sectional images of your body. It can show if the celiac artery (a blood vessel supplying the stomach and intestines) is narrowed or blocked. A contrast dye might be used, making the blood vessels easier to see in the images. This is called a CT angiogram.
Celiac plexus block: A numbing medicine is injected into the nerves surrounding the celiac artery. This temporary numbness mimics what happens during surgery to treat MALS. This test helps doctors determine if surgery might be a good option for a patient.
These tests help healthcare professionals narrow down the possible causes of your symptoms and determine if MALS is the problem.
Median arcuate ligament syndrome (MALS) is a condition that needs surgery to treat it. This surgery can help many people by either lessening or getting rid of the symptoms. There's no other way to treat MALS currently.
Experiencing pain and stress can often be a vicious cycle. Pain can trigger feelings of stress, and stress can worsen pain. Median arcuate ligament syndrome (MALS) pain can make everyday activities like eating, exercising, sleeping, and even simple chores challenging.
Fortunately, there are ways to break this cycle. Relaxation techniques, like deep breathing exercises and meditation, can help reduce pain and improve your overall mental well-being. These techniques can help you feel calmer and more in control. By practicing these techniques regularly, you might find it easier to manage your pain.
If you have MALS, the National MALS Foundation is a valuable resource. They offer information and connect people with others who understand what you're going through. They can provide support and guidance. Also, don't hesitate to ask your doctor or other healthcare provider to recommend support groups in your area. Connecting with others facing similar challenges can provide invaluable emotional support and practical advice.
If you're experiencing persistent stomach pain or other symptoms that might be related to median arcuate ligament syndrome (MAL syndrome), schedule a visit with your doctor.
Doctor's appointments can be busy, so preparing beforehand helps ensure you get the most out of your time. It's a good idea to be well-prepared. Taking the time to write down your questions and concerns is a helpful step.
