Many possibilities: The list of possible causes includes: gallstones, biliary duct obstruction and infection, gastritis, peptic ulcers, gastroesophageal reflux disease, pancreatitis, diverticulitis, strangulated hernia, diabetic gastroparesis. Other information such as time of onset, relation to meals, duration of symptoms, weight loss, nausea/vomiting/diarrhea, bleeding. Gyn history would all be helpful - good luck.
