Tuberculosis patients should not drink alcohol because alcohol is a stimulating food that can damage the gastrointestinal tract and the liver. If a large amount of alcohol is consumed at one time, serious stomach bleeding can occur and alcoholic liver damage can be caused to the liver. If anti-tuberculosis treatment is given at the same time, the most common side effects of anti-tuberculosis treatment drugs are gastrointestinal reactions and damage to the liver. If alcohol is consumed, the gastrointestinal reactions will be significantly aggravated, which may lead to vomiting, diarrhea, or in severe cases, stomach bleeding, and liver damage will also be significantly aggravated, which may lead to loss of appetite, jaundice, and significant increase in ghrelin, or in more severe cases, liver failure. If TB patients drink alcohol, it may not only affect the anti-TB treatment and lead to forced interruption of TB treatment, but also serious liver damage and gastrointestinal reactions.
