Postnasal Drip
The different parts of the human body naturally produce mucus, a wet substance that helps trap and destroy microorganisms and foreign particles that may cause harm or infection. The nose, stomach, airways, and intestinal tract are some body parts that produce mucus daily. Usually, mucus from the nose mixes with saliva and goes down the throat without being noticed. However, there are times when the body makes thicker mucus. For example, a runny nose happens when the excess mucus goes out of the nostrils; postnasal drip occurs when the mucus goes down from the nose to the throat.
Postnasal drip is caused by the extra mucus accumulating in the back of the throat and nose. It can be triggered by fumes, colds, allergies, deviated septum, particular foods, and weather changes. It is among the most common causes of hoarseness, sore throat, persistent cough, belching, and other annoying symptoms.
Because of a lump feeling at the back of the throat, people with postnasal drip often develop swallowing problems. In addition, swallowing more often than usual may lead to more gas ingestion, leading to persistent belching. Drinking more fluids can help in these situations.
