Intestinal tuberculosis is a chronic intestinal infection caused mainly by Mycobacterium tuberculosis and is primarily caused by swallowing sputum containing Mycobacterium tuberculosis. A few people also develop bovine M. tuberculosis intestinal tuberculosis from drinking unpasteurized milk with bacteria. In addition, M. tuberculosis can also be contracted through the blood-borne route with the human type of Mycobacterium tuberculosis. The onset of intestinal tuberculosis is the result of the interaction between the body and Mycobacterium tuberculosis, and generally occurs when there is a high number of Mycobacterium tuberculosis in the intestine, abnormal immune function of the body, and a combination of intestinal dysfunction. Most of the cases start slowly, commonly with abdominal pain in the right lower abdomen, accompanied by diarrhea, constipation, low-grade fever, and night sweats. The severity of diarrhea varies according to the degree of development of the lesion, and in severe cases it can be more than 10 times a day. The key to the treatment of intestinal tuberculosis is to choose the right anti-tuberculosis drugs, and patients who develop complications such as intestinal perforation need to be treated surgically. Patients should take more rest, pay attention to a light diet, eat easily digestible food, maintain a balanced nutrition, avoid spicy and stimulating foods, and do not drink or smoke. Prevention is very important for the spread of the disease, and when eating with such patients, public dishes should be sterilized at high temperature before use, and BCG vaccination can be given to strengthen their resistance.
