What Are the Causes of Sinus Drainage?

The sinuses are a large, empty space located behind the nose and eyes that prevents unwanted air particles from entering the body. The sinuses are used as a preliminary air filter for the lungs. They are very sensitive and are easily irritated by different environments, allergies and various foods. When the sinus cavity is irritated or infected, it produces excess mucus resulting in congestion and drainage.

  1. Facts

    • Sinus drainage is the body's way of reacting to an abnormal substance entering into the nasal cavity. The sinus cavity is covered by a think layer of light mucus. When it is irritated, the sinus cavity becomes inflamed and begins to produce more mucus to rid itself of any impurities. This causes the nose to run, the throat to become irritated and at times, a cough to develop.

    Common Cold

    • According to the May Clinic, the average American will suffer from the common cold 2 to 4 times in 1 year. The common cold is an infection in the eyes, nose, ears and/or throat that causes excess mucus and congestion. When an individual begins to take medication for the cold, it loosens the blocked passageways, allowing the mucus to flow freely, resulting in a lot of nasal drainage.

    Prevention

    • In order to prevent sinus drainage, an individual can take an over-the-counter decongestant that will dry up the excess mucus and reduce the swelling in the sinus cavity. Maintaining a strong immune system also will help an individual from developing sinus drainage. This is easily accomplished by eating wholesome foods, drinking at least 6 8-ounce glasses of water daily and getting a minimum of 8 hours of sleep a night.

    Allergies

    • Another cause of sinus drainage is allergies. People who suffer from common allergies experience a lot of sinus drainage due to an irritation throughout the body. People who suffer from seasonal allergies can easily alleviate this issue by taking an over-the-counter antihistamine on a daily basis. An antihistamine will fight off any allergic reactions, therefore reducing the body's response of excessive nasal drainage.

    Identification

    • Sinus drainage caused by the common cold can be accompanied with a fever, severe head congestion, sinus pressure and pain, the chills and headaches. Sinus drainage caused by allergies will demonstrate signs such as water eyes, sneezing and an itchy throat and inner ear. Identifying the cause of the nasal drainage will assist the individual in treating and preventing the condition to persist in the future.
