A lump or bulge in the abdomen that appears to pulsate can be a sign of an aortic aneurysm. A lump or bulge can also be related to a benign tumor such as a lipoma. Gas pains, indigestion, and Constipation can sometimes cause the perception of a distended stomach. If you are experiencing any of these symptoms and they do not improve, seek the advice of a health care provider. Seek immediate medical attention if you have a lump or bulge in the abdomen that is pulsating.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Angiomyolipomas are noncancerous tumors that are typically found in the kidney, but may occur in the liver, ovary, colon, or Fallopian tube. Symptoms and signs include shock, chronic kidney disease, anemia, vomiting, nausea, and back or flank pain. Treatment may involve taking medication and embolization of the tumor.
Abdominal Aortic Aneurysm
Abdominal aortic aneurysm is a ballooning or widening of the main artery (the aorta) as it courses down through the abdomen. Most abdominal aortic aneurysms produce no symptoms. Treatment may include observation or surgical repair.
Indigestion (dyspepsia) can be caused by diseases or conditions that involve the gastrointestinal (GI) tract, and also by some diseases and conditions that do not involve the GI tract. Indigestion can be a chronic condition in which the symptoms fluctuate in frequency and intensity. Signs and symptoms that accompany indigestion include pain in the chest, upper abdominal pain, belching, nausea, bloating, abdominal distention, feeling full after eating only a small portion of food, and rarely, vomiting.
Intestinal Gas (Belching, Bloating, Flatulence)
Gas (intestinal gas) means different things to different people. Everyone has gas and eliminates it by belching, burping, or farting (flatulence). Bloating or abdominal distension is a subjective feeling that the stomach is larger or fuller than normal. Belching or burping occurs when gas is expelled from the stomach out through the mouth. Flatulence or farting occurs when intestinal gas is passed from the anus. Causes of belching or burping include drinking too rapidly, anxiety, carbonated drinks, habit, and swallowing air. Learn about causes of intestinal gas, foods that cause gas and bloating, treatments that reduce excessive gas and soothe gas pain, and much more.
