The diagnosis of the primary disease or cause of diarrhea must be based on medical history, symptoms, signs, routine tests, especially stool tests. In many cases, a careful diagnosis can be made by careful analysis of the medical history and preliminary results of the above examinations. If the diagnosis is still unclear, X-ray barium enema and barium meal examination, and/or straight and colonoscopy may be performed. If there is still no clear conclusion, ultrasound, CT, endoscopic retrograde cholangiopancreatography (ERCP) and other image diagnosis methods should be used to check the gallbladder and pancreatic diseases, or the small intestine absorption function test, breath test, small intestine. Mucosal biopsy to check for poor intestinal absorption. Highly suspected diseases such as intestinal tuberculosis and intestinal amoebia have special treatments. If they are unable to confirm the diagnosis, they can be treated within a certain period of time.
Diagnosis
Differential diagnosis
1. Infant acute rash: more common in children under 1 year old, children under 6 months are more common, rash often occurs before rash, some accompanied by diarrhea, but this diarrhea is easy to relieve after treatment, rash after diarrhea Symptoms, like fever, disappeared.
