[|Human|] I have been having upper abdominal pain and possible gallbladder problems. I am having a HIDA scan tomorrow. Yesterday and today I have been having black stool. It s not all black but is between the size of a dime up to a quarter. Smells foul. I haven t been eating anything that would give that color. Is this something I need to be concerned about? I am 56 yrs old female and overweight. I had my follow up colonoscopy in January which was fine. Ultrasound showed no abnormality when I had that done 2 weeks ago.
[|AI|]  Hi. Your history and old reports noted. The black stools with foul smelling stools is suggestive of gastroenteritis with bleeding somewhere in the intestines, may be due Gastroenteritis. The u[per abdominal problem can suggest a gastric ulcer or cancer, upper GI Endoscopy will help to find out. Get a treatment with PPI, Antibiotic and supportive medicines. HIDE scan and other tests will help to get to a proper diagnosis and treatment.
