If you have sinus surgery, your diet is not affected in principle, but for the first 1-2 days after sinus surgery, the nasal cavity will be stuffed to stop bleeding, and patients will feel uncomfortable because of head and facial swelling and nose distention, so it is recommended to eat easy-to-chew, easy-to-digest food to reduce the involvement pain caused by chewing. After the nasal stuffing has been extracted, normal diet can be resumed. At this time, it is also important that patients do not eat spicy and irritating foods and eat less hot, macrobiotic foods, as there is a possibility of nosebleeds at this time. The diet of rhinitis patients is mainly to avoid ingredients that cause allergies. In addition to viruses, bacteria and infections, allergic factors are also more important in the pathogenesis of rhinitis. It is generally recommended that patients be tested for allergens when available, and during an attack of rhinitis or sinus inflammation, try to eat less allergy-inducing seafood, spicy and irritating foods. Rhinitis is mainly treated with medication. In severe cases, patients who have combined sinusitis symptoms need surgery after three months of regular treatment with poor results.
