<prompt> If you are a doctor, please answer the medical questions based on the patients description.hi I have pain and swelling over my belly button and it hurts almost everytime I eat and drink, it always makes me look pregnant. when the pain starts I have to put a warm pillow on it and it also churns like gas, please tell me what you think it could be besides gas.  <response>: Hi. This is not just a gas. This is indicative of an obstruction somewhere in the GI tract, or may be a pseudocyst of pancreas, stomach outlet obstruction and so on. The best diagnosis is made by the following:-Upper GI Endoscopy-Ultrasonography to start with.-Confirmation by contrast enhanced CT scan of the whole abdomen.-Enterocolitis if required. Once the diagnosis is made, treatment can be decided according to the findings and patient be prepared well in advance for a better outcome of the surgery. This is done by getting the hemoglobin and serum proteins, multivitamins corrected as such patients will have multiple deficiencies.
