Tuberculosis enteritis is clinically known as intestinal tuberculosis, which is caused by infectious lesions in the intestines invaded by Mycobacterium tuberculosis, leading to abdominal pain, change of bowel habit, abdominal mass and tuberculosis poisoning symptoms. 1. Abdominal pain: abdominal pain is one of the most common symptoms caused by intestinal tuberculosis, which is mainly manifested as persistent hidden pain, but once the development of the disease causes intestinal obstruction or intestinal perforation, it will cause severe abdominal pain. 2. Change of bowel habit: Tuberculosis may also bring about change of bowel habit, which may be diarrhea, constipation, or diarrhea and constipation alternately. 3. Abdominal lumps: the occurrence of intestinal tuberculosis may also lead to the patient’s lower abdomen with unusual lumps, which may be painful when pressed. 4. Tuberculosis poisoning: Tuberculosis poisoning is a kind of systemic symptom caused by intestinal tuberculosis, which is mainly manifested as fever, night sweating (sweating abnormally after going to sleep, but the sweating stops after waking up), weight loss, and body weakness. Early stage of TB is characterized by reversibility, so individuals should strive to diagnose and treat the disease at an early stage. It is important to seek medical attention as soon as possible if symptoms of suspected intestinal tuberculosis appear.
