Because anti-tuberculosis drugs have obvious side effects, they can stimulate the gastrointestinal tract and cause regurgitation, nausea and vomiting. At the same time, anti-tuberculosis drugs can cause liver damage, which can also lead to regurgitation, so when patients have regurgitation, they should review their liver function and adjust their anti-tuberculosis treatment plan if they have abnormal liver function, followed by active liver protection therapy. If it is only caused by damage to the gastric mucosa, you can take oral acid-suppressing drugs to protect the gastric mucosa, such as omeprazole and pantoprazole. You must eat more fruits and vegetables in your diet and avoid spicy, stimulating, greasy and indigestible foods.
