Do I have Superior Mesenteric Artery Syndrome?


Superior Mesenteric Artery Syndrome (SMAS) is a rare condition that occurs when the duodenum (the first part of the small intestine) becomes compressed between two major blood vessels in the abdomen, namely the aorta and the superior mesenteric artery. This compression can lead to various symptoms and complications, making it important to recognize the signs of SMAS.



One of the key indicators of SMAS is severe and persistent abdominal pain. This pain is typically located in the upper abdomen, around the navel area, and may worsen after eating. The pain can be described as cramp-like or colicky, and it may be accompanied by bloating, nausea, and vomiting. The severity of the pain can vary from person to person, but if you experience intense and ongoing abdominal discomfort, it is advisable to seek medical attention.



Another important symptom of SMAS is significant weight loss. This occurs due to the reduced ability to eat and digest food properly. The compression of the duodenum can lead to a feeling of early satiety, meaning you feel full quickly even after consuming small amounts of food. As a result, you may unintentionally lose weight over time. If you notice a significant and unexplained drop in your body weight, it is worth discussing with a healthcare professional.



Other potential signs of SMAS include abdominal distension, constipation, and even episodes of vomiting blood. These symptoms can occur due to the obstruction and pressure on the digestive system caused by the compressed duodenum. If you experience any of these symptoms, it is crucial to consult a medical expert for a proper evaluation and diagnosis.



Diagnosing SMAS involves a combination of medical history assessment, physical examination, and diagnostic tests. Your healthcare provider may ask about your symptoms, perform a physical examination to check for abdominal tenderness or distension, and order imaging tests such as an upper gastrointestinal series or a CT scan. These tests can help visualize the anatomy of the abdomen and identify any compression or narrowing of the duodenum.



If you suspect you may have SMAS, it is essential to consult a healthcare professional promptly. They will be able to evaluate your symptoms, conduct the necessary tests, and provide appropriate treatment options. Early diagnosis and intervention can help manage the condition effectively and prevent potential complications.
