Consider pain above the belly button and diarrhea caused by enteritis, mostly due to bacterial or viral infections. Of course, care needs to be taken to exclude other acute abdominal conditions, such as abdominal pain and diarrhea caused by appendicitis, cholecystitis or pancreatitis. Patients with abdominal pain and diarrhea are advised to choose to observe or use medication, if necessary, depending on the severity of clinical symptoms. For mild abdominal pain and diarrhea, if it is initially judged to be caused by intestinal diseases or improper diet, then it can be temporarily observed or treated with appropriate oral probiotics. If the symptoms of abdominal pain and diarrhea are more serious, it is recommended to go to the hospital in time and cooperate with the doctor to improve relevant examinations, such as blood routine, blood biochemistry, stool routine, C-reactive protein, electrocardiogram, abdominal ultrasound and other related examinations.
