Some patients with allergic cough may develop skin allergies and need to take antihistamines to treat it. Nebulized glucocorticoids and other medications can improve airway inflammation. If the allergens are identified, such as pollen, dust, dust mites, seafood, etc., it is advisable to avoid contact with these allergens as much as possible. A light diet should be maintained by avoiding overly spicy, stimulating, and greasy foods, such as chili peppers, Sichuan peppercorns, and grilled meats, as these can exacerbate allergies and are not conducive to recovery. It’s important to stay hydrated and eat plenty of fresh vegetables and fruits, such as apples, oranges, and pears.
