  • Abdominal angina


    Abdominal angina is abdominal pain after eating that occurs in individuals with ongoing poor blood supply to their small intestines known as chronic mesenteric ischemia. Although the term angina alone usually denotes angina pectoris (a type of chest pain due to obstruction of the coronary artery), angina by itself can also mean "any spasmodic, choking, or suffocative pain", with an anatomic adjective defining its focus; so, in this case, spasmodic pain in the abdomen. Stedman's Medical Dictionary Online defines abdominal angina as "intermittent abdominal pain, frequently occurring at a fixed time after eating, caused by inadequacy of the mesenteric circulation resulting from arteriosclerosis or other arterial disease. Synonym: intestinal angina."

  • Peritonitis


    Peritonitis is inflammation of the peritoneum, the lining of the inner wall of the abdomen and cover of the abdominal organs. Symptoms may include severe pain, swelling of the abdomen, fever, or weight loss. One part or the entire abdomen may be tender. Complications may include shock and acute respiratory distress syndrome. Causes include perforation of the intestinal tract, pancreatitis, pelvic inflammatory disease, stomach ulcer, cirrhosis, or a ruptured appendix. Risk factors include ascites and peritoneal dialysis. Diagnosis is generally based on examination, blood tests, and medical imaging. Treatment often includes antibiotics, intravenous fluids, pain medication, and surgery. Other measures may include a nasogastric tube or blood transfusion. Without treatment death may occur within a few days. Approximately 7.5% of people have appendicitis at some point in time. About 20% of people with cirrhosis who are hospitalized have peritonitis.

  • Abdominal pain


    Abdominal pain, also known as a stomach ache, is a symptom associated with both non-serious and serious medical issues. Common causes of pain in the abdomen include gastroenteritis and irritable bowel syndrome. About 10% of people have a more serious underlying condition such as appendicitis, leaking or ruptured abdominal aortic aneurysm, diverticulitis, or ectopic pregnancy. In a third of cases the exact cause is unclear. Given that a variety of diseases can cause some form of abdominal pain, a systematic approach to examination of a person and the formulation of a differential diagnosis remains important.
