Reasons You May Have a Bad Smell in the Nose

Encountering a foul smell is unfortunately just a part of life. But if you have a bad smell in your nose that lingers or has no apparent external source, it may be caused by an underlying medical condition. Below are several reasons you may be experiencing a bad smell in the nose.

Sinusitis

Sinusitis, more commonly known as a sinus infection, affects nearly 31 million people in the U.S. It causes symptoms like sinus pressure, congestion, drainage, facial pain, headache and bad breath. Another lesser-known side effect is bad smell. The smell is caused by discharge that drains through the nose and down the back of the throat.

Most cases of sinusitis last between three and eight weeks; infections that persist longer than 12 weeks are referred to as chronic sinusitis. Fortunately, sinusitis usually clears up on its own, although antibiotics may be recommended for severe cases.

Poor Dental Hygiene

Cavities can trap bacteria and release unpleasant gasses like sulfur as it breaks down. These gasses can travel through small holes in the back of the mouth that connect to the sinuses and cause a bad smell in the nose.

Cavities are caused by tooth decay and gingivitis. Brushing twice daily, flossing once daily and getting a dental cleaning every six months are the best ways to prevent bad smell in the nose caused by dental problems.

Tobacco Use

Cigarettes and chewing tobacco contain chemicals that weaken teeth and gums, causing bad breath, dental disease and sometimes bad smell. In addition, smoking can reduce your ability to taste and smell properly, so you perceive smells as foul that may not be.

Quitting tobacco can reduce bad smell in your nose, along with having a number of other health benefits.

Digestive Problems

Conditions like acid reflux can cause bad taste in the mouth and foul smell in the nose. Other conditions that are linked to bad smell, albeit more rarely, include diabetes, liver disease, and kidney disease.

Seeking treatment from a local ENT for the underlying conditions can prevent bad smell.
