Major Causes Of Post-Nasal Drip

Allergies

Allergy patients may develop post-nasal drip when exposed to allergens. Some of the most common allergens in the environment include grass, pollen, dust, mold, and pet dander. If a patient suspects they may be allergic to particular substances, they should visit an allergist, who can perform a skin test to determine precisely what substances the patient needs to avoid. Patients who experience post-nasal drip due to allergens may wish to use decongestants to relieve a stuffy nose and reduce mucus. Antihistamines can help relieve nasal symptoms. Doctors may also recommend periodic injections for more severe cases. Patients may be advised to modify their home environments by using a HEPA air filter and avoiding contact with pets. Bedding and toys should be washed frequently, and patients will benefit from the use of a home humidifier.

Spicy Foods

Consumption of spicy foods often triggers acid reflux and can lead to the development of gastroesophageal reflux disease, a recognized cause of post-nasal drip. Acid reflux and gastroesophageal reflux disease destroy the lining of the esophagus and can cause painful ulcers in the throat. Patients with either of these conditions need to avoid spicy foods, and they should particularly avoid foods high in acid. Tomatoes and tomato sauce, processed meats, peppers, onions, garlic, citrus fruits, ketchup, mint, caffeine, and chocolate are all common triggers for acid reflux. Patients who struggle with post-nasal drip may wish to ask their doctor or a nutritionist for additional dietary advice to minimize their symptoms. Keeping a food diary and noting any episodes of post-nasal drip or reflux that occur after a meal can be useful too.
