Health Updates: Reason Behind Bad Breath!


Reason Behind Bad Breath: It is normal to have bad breath if you do not clean your mouth regularly. But if your mouth still smells even after brushing, it can be a matter of concern.


Bad breath usually does not indicate any serious reason. Because this smell depends on food habits and oral hygiene. Therefore, dentists recommend brushing twice a day and rinsing with water after every meal.

But if your mouth still smells bad despite taking care of oral hygiene, it can be a sign of some serious disease growing in the body. Yes, according to Hopkins Medicine, bad breath has been identified as an early sign of many dangerous diseases. In this article, we are telling you about these 5 diseases.

Respiratory tract infection

Respiratory infections like sinusitis, bronchitis, and pneumonia increase the level of volatile sulfur compounds (VSC) in the body, which causes bad breath. Also, when these infections occur, bacteria grow in the respiratory tract, which leads to the formation of odor-producing elements and they are released with exhalation. 

Digestion problem 

Bad breath is related to digestive disorders such as acid reflux, gastroesophageal reflux disease (GERD), and stomach ulcers. Acid reflux occurs when stomach acid moves back into the esophagus, causing a sour taste and smell in the mouth. 

Kidney Disease

Kidney disease affects the body's ability to remove waste from the body. In such a situation, due to the high amount of toxins in the blood, the breath starts smelling like ammonia, which is also called uremic breath.


Bad breath is caused by high sugar levels in the body for a long time. This is a very common problem in people with diabetes. This is because their breath contains high amounts of ketones which produce a fruity smell, known as 'acetone breath'.

Liver disorders

Due to liver problems like cirrhosis or fatty liver disease, the toxins in the body are not metabolized properly. This is the reason why bad breath occurs when there is a problem in the liver.
