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.
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.
