All TB patients should not eat foods that are too spicy and irritating, nor should they eat foods that are too greasy, such as fried foods, nor should they drink alcohol. Patients with intestinal tuberculosis should not eat foods with too much dietary fiber, such as leeks and celery, and should eat foods with less residue to avoid complications such as intestinal bleeding or intestinal perforation. Tuberculosis is a wasting disease that causes prolonged symptoms such as low fever, night sweats and coughing, which can cause anemia, emaciation and loss of appetite in the long term. Application of anti-tuberculosis drugs can cause side effects of the drugs, which can lead to gastrointestinal reactions and liver damage. Excessively spicy and stimulating food can stimulate the mucous membrane of the gastrointestinal tract and aggravate gastrointestinal reactions, which may cause diarrhea, nausea, vomiting and other symptoms. Drinking alcohol can lead to liver damage, and overly greasy food is not easily digested and can cause diarrhea and other symptoms.
