Post nasal drip is the feeling that mucous is accumulating in the throat or dripping from the back of your nose. Post nasal drip is caused by excessive or unusual mucous secretion from the glands of the nose and throat. These glands actually produce one to two litres of mucous a day; it is normally swallowed unconsciously. This mucous moistens and cleans nasal passages, humidifies air, fights infection, and traps and clears inhaled foreign matter. Post nasal drip occurs when mucous becomes too thick or thin as a result of infection, irritation, or an allergic reaction. Post nasal drip can also result from throat and swallowing disorders.

For most people, post nasal drip begins in the nose; in fact, more than 90% of infection-causing bacteria and irritants enter the body through the nose and thrive in the nasal passages. When viruses and other pollutants enter the nose, the body reacts by sending white blood cells to the lining of the nose and produces additional mucous to wash away irritants.

This often results in congestion. As we blow our nose to relieve congestion, cough, and swallow phlegm, bacteria are forced into the ears, sinuses and throat.

Post nasal drip can be irritating and uncomfortable. Post nasal drip often leads to a sore, irritated throat and even swelling of the tonsils. It can also lead to or result from upper respiratory infections, such as an ear or sinus infection. Post nasal drip can be avoided or at least reduced by regularly using a nasal wash. Most of us wouldn't go a day without washing our hands, at least a few times, but do nothing to flush away the harmful bacteria that lead to post nasal drip. Saline nasal sprays are an excellent remedy for daily nasal cleansing. Although they moisturise and keep the nose healthy, saline nasal sprays, alone, do little to combat bacterial and viral growth that leads to post nasal drip.
