Patients are not allowed to eat or drink yogurt within six hours after tonsillectomy because they are in a fasting state after surgery, and drinking yogurt can easily stimulate the mucous membrane of the stomach and cause nausea, vomiting and acid reflux. Patients can drink plain milk after surgery, which can protect the gastric mucosa. After 2-3 days, patients can eat normally and then consider drinking yogurt. However, you must rinse your mouth after drinking to avoid having yogurt residue, which may lead to the formation of anaerobic bacteria inside the mouth. After the tonsillectomy, it is recommended to actively apply anti-inflammatory drugs and hemostatic drugs to consolidate the treatment for about a week, and the patient’s tonsillectomy should improve significantly after active symptomatic treatment. In life, patients must exercise more to avoid inflammation of the tonsils to avoid surgical removal.
