A bad taste in the mouth feels unpleasant and there are times when we can feel our own bad breath. Sinusitis is a disease in which the sinus cavities which are located in head become inflamed. One of the major symptoms of this disease is bad breath and bad taste which is also known as bad taste sinus disease.
Normally, the nose and sinuses produce a quart of mucus secretions per day. This passes through the nose and picks up dust particles, bacteria and other pollutants which are present in air along the way. Tiny hair like structure called cilia which line through the nasal cavity sweep the mucous to the back of the throat and then it is swallowed. The acid which is present in the stomach destroys any harmful bacteria that are present in the mucous.
The main cause due to which this disease occurs is post nasal drip. Sinuses are basically a part of the nasal passage which produces mucous. This mucous then flows into the throat causing a bad taste in our mouth. Swallowing the mucous is not risky because the stomach destroys any harmful bacteria that are present in the mucous. It can only be risky if it spreads to the brain or the eyes which occurs in a very rare case. If the post nasal drip enters the lungs it can be very dangerous. Smoking whether active or passive, should be avoided completely. Proper oral hygiene and proper cleaning of the nose also helps avoiding sinus.
