Hello, You had an ultrasound done and the report did not show anything. Now, you are experiencing bulge above the stomach after eating. You are suggested to maintain healthy weight if obese. Do regular walking and exercises. Take home made food cooked in olive oil and avoid spicy, oily food. Avoid trans fat, full fat dairy products, cheese, red meat and food that causes you allergy and bloating. Lump or a bulge, fullness, distended stomach can be due to IBS or constipation. It can also be caused by lipomas, hernias, tumors, etc. Control of diet and exercise, weight reduction are helpful. Avoid constipation, take laxatives at bed time, take food rich in fiber. Take small amount of food multiple times a day. For relief, you can take antacids and PPIs, one sos when needed. It should get reduced. If not have a follow up clinical examination & imaging tests done to detect the cause of discomfort. Take care. Hope I have answered your question. Let me know if I can assist you further.
