Post-nasal drip (PND) is a very common problem that is happening due to excessive mucus production by the nasal mucosa. This is a very uncomfortable and irritating situation to deal with, and it can affect people of all ages.
Glands in your airways, throat, and lining of your nose continually produce mucus which is a kind of thick and wet substance. It cleans and moistens the nasal membranes, fights infections, traps and clears inhaled foreign matter, and humidifies the air in the airways. It is normal not to notice the mucus from your nose as you swallow it unconsciously throughout the day. But when the mucus is overproduced, then the mucus starts dripping from the back of your nose, and this causes post–nasal drip.
Additional symptoms can include a general feeling of weakness, difficulty swallowing, congestion, coughing, and irritated or sore throat. There are many different causes that can trigger post–nasal drip, such as smoke, fumes from cleaning products, perfumes and fumes from chemicals, hormonal changes in the body, certain medications, spicy food, excessively dry air, cold temperature, sinus infection, allergies, flu, and the common cold.
