Bad breath (termed as halitosis) is common and can affect almost anyone. Most often, the bad odor comes from the oral cavity.

What causes bad breath coming from the nose?

A bad breath from nose may have many causes, the most prevalent being a post nasal drip. During a post nasal drip, the excess mucus tends to trickle from the back of the nose.

The mucus may cause a coating in the back of the tongue, which provides a perfect bed for bacteria to thrive.

Since these bacteria emit a foul odor, it passes with breath through the nasal cavity. That being said, people suffering from sinusitis and post nasal drip often show such bad breath coming from the nose.

Another reason for a smelly nose is an underlying medical condition that induces bad odor.

Diabetes and liver diseases are most common causes of bad breath. Allergies that causes stuffy nose may also lead to foul odor from the nasal cavity, which goes off naturally when the problem is addressed.

A polyp in the nasal cavity or any blockage is also related with bad breath. Minute objects stuck in the nostrils may produce a bad odor in small children. Apart from this, a high temperature may also cause built up of bacteria leading to bad breath.

How to cure bad breath from the nose?
