Diarrhea with pain around the navel may be related to cold, acute gastroenteritis, food poisoning and so on. 1. Cold: If the patient usually do not pay attention to abdominal warmth, when the surrounding environment temperature is too low, it may lead to abdominal cold. The gastrointestinal muscles contract and spasm excessively because of the cold, and the gastrointestinal tract peristalsis speeds up, which leads to the patient’s symptoms of diarrhea around the navel pain. 2. Acute gastroenteritis: If the patient eats unclean food, he may be infected with E. coli. The bacteria stimulate the intestinal mucosa, which makes the intestinal absorption of sodium and water impaired, and the toxins released by the bacteria will stimulate intestinal peristalsis, which leads to the symptoms of diarrhea around the navel pain. 3. Food poisoning: If the patient has recently consumed toxic foods, such as cassava, white fruit, sprouted potatoes and so on. These foods contain linseed, hydrocyanic acid toxin, lobelia alkaloids, after entering the human body, the intestinal mucosa will have a certain stimulating effect, thus making the patient appear around the navel pain diarrhea symptoms. 4. Intestinal tuberculosis: Mycobacterium tuberculosis infection of the intestinal tract leads to localized exudation, hyperplasia and diarrhea with pain around the navel. You can take rifampicin, isoniazid, pyrazinamide and other drugs for treatment. If the patient has the symptom of diarrhea with pain around the navel, he should go to the hospital in time, improve the relevant examination, clarify the cause of the disease, and follow the doctor’s instructions for treatment.
