Going to the bathroom immediately after eating may be related to intestinal disorders, gallbladder disorders, pancreatic disorders, etc. 1. If you suffer from irritable bowel syndrome, chronic enteritis, etc., when stimulated by external food, it will make you want to have a bowel movement. 2. If the gallbladder is removed, it can lead to insufficient bile secretion, which can cause indigestion and diarrhea when eating fatty foods. 3. If after pancreatectomy or pancreatitis surgery, due to insufficient exocrine function of the pancreas, it can lead to diarrhea symptoms. There may be other causes of diarrhea, so it is recommended to go to a regular hospital in time to clarify the cause of the disease, and to carry out standardized treatment under the guidance of the doctor, so as not to delay the disease and bring adverse effects to the body.
