Causes of Post Nasal Drip

Post nasal drip is a medical condition wherein mucus accumulates in the back of the nose and throat, due to the over-production of mucus by the sinuses leading to the sensation of mucus dripping at the back of the throat. Here are the common causes of post nasal drip that should be accounted for to have a better understanding of this illness:

1.) Inhaled irritants: Polluted air harbor particles that can invade a person’s respiratory system and induce swelling in the nasal and sinus region.
2.) Smoking: Chemicals in cigarettes can inflame the nasal mucosal membrane and can lead to excessive mucus production. Cilia can be damaged by smoking thus inhibiting the movement of the mucus.
3.) Alcohol and caffeinated drinks: These diuretic substances can lead to the stagnation of the mucus due to their dehydrating property.
4.) Ingesting allergy-causing food: Allergic reactions inside a person’s body can trigger the thickening of mucus and impair nasal clearance.
5.) Dairy products: This food type is health food for many but is a detriment to post nasal drip sufferers because it can cause mucus to thicken and can make the efficient drainage of mucus tough.
6.) Living in dry regions: Arid areas or even dry air from air conditioners can desiccate the mucus in the nasal lining which would be troublesome to get rid of. Furthermore, the inert mucus can be habitat for the growth and proliferation of bacteria.
7.) Colds and flu: A compromised immune system, as what you see when a person has colds or flu, is an easy target for afflictions in the respiratory tract.
8.) Swallowing disorders: Difficulties in swallowing or throat may very well progress into the immobility of the mucus in the throat which can bring about an increase in mucus secretions.
9.) Pregnancy and contraceptive pills: Birth control pills can cause fluctuation of hormones in females, which could make them susceptible to post nasal drip.
