I have had diarrhea for about 10 months this is accompanied by weight gain fatigue rectal bleeding (ulcers) abdominal pain, & vomiting. This only started after I was hospitalized for ischemic colitis, & infection. I have been through many tests. Blood test, endoscopy, colonoscopy you name it the only thing found was a little thickening of the small intestine, but my G.I. cannot come up with a diagnosis. I am desperate I live as aHermit in my home. I can t really leave my home due to my frequent urges to use the restroom! I m hoping you my have a idea or suggestion on what this could be!
