People with adenoid hypertrophy need to avoid spicy and stimulating foods in their diet, and allergic foods should be prohibited. Adenoid hypertrophy mostly occurs in children, and its occurrence is related to chronic nasopharyngeal infection, which has little to do with diet, but patients may have difficulty swallowing, loss of appetite and other symptoms due to the condition. Patients need to ensure nutrition, pay attention to a light diet, and avoid spicy and stimulating foods that irritate the throat, such as chili peppers, jalapeno peppers, garlic, onion, mustard, etc., as well as spicy-flavored dishes. Allergy sufferers should be cautious of eating foods that are prone to allergy, such as seafood and mango. People with enlarged adenoids need to go to the Ear, Nose and Throat (ENT) Department at an early stage, follow the doctor’s instructions to standardize the treatment, and pay attention to the nose to keep warm and prevent colds.
