Sinusitis patients are forbidden to eat spicy and stimulating food, prohibit strenuous exercise in the early postoperative period, and prohibit smoking and alcohol. 1. Prohibit eating stimulating food: In the early postoperative period, the patient’s nasal cavity is filled with gauze, and it is advisable to maintain a light diet. Avoid spicy or stimulating food, such as hot pot, spicy food, etc., otherwise it may cause the patient to experience symptoms such as tingling at the surgical site. 2. Prohibit strenuous exercise in the early postoperative period: After surgery, as the surgical wounds are not completely healed, it is prohibited to run, jump and other strenuous exercise, and also prohibited to blow your nose. 3. Prohibition of smoking and alcohol: smoking and alcohol should be prohibited for a short period of time after the operation to avoid the stimulation of the nasal cavity caused by such substances, which is not conducive to the recovery of the disease. After the operation, patients should follow the doctor’s instructions to take medication, regular review, pay attention to rest, avoid staying up all night and exertion, and reduce the number of people going in and out of areas with dirty environment. If nasal and head discomfort occurs, it is necessary to follow up with the surgeon in a timely manner.
