• Dr. Andrew Ordon of "The Doctors" says sinusitis is a common cause of bad breath.
• Sinusitis may also causes other side effects, such as headaches, facial pain and pressure.
• Treating sinusitis can be both simple and low-risk.

On an episode of the talk show "The Doctors," Dr. Andrew Ordon responded to a viewer's question about whether untreated sinusitis can cause bad breath.

"Yes, for sure," Ordon said on the television show. "The minute that those sinuses get clogged up, you have a buildup of mucus; bacteria grow in there. They cause an odor that spreads, not only into the nasal cavities, but down into your mouth. In fact, bad breath is one of the major symptoms of sinusitis."

Dr. Andrew Ordon has worked as a surgeon for over 30 years. He is a two-time Emmy nominee for his role as cohost of "The Doctors," which is a daily syndicated talk show that features doctors offering medical advice to viewers.

Dr. Manish Khanna of Capitol Breathe Free Sinus & Allergy Centers explains the additional sinusitis symptoms that patients may experience.

"Our nasal passages are really the center of our head," Khanna told Maryland Business Daily. "Problems in our nasal passages affect our ears, our eyes, cause eye pressure; it affects our throat. All this is connected, but also further down when you get into the lungs, chronic sinus issues and recurring sinus issues can trigger asthma exacerbation and reactive airway disease. There's so many organ systems that are that are touched by our nasal passages. Proper health there can make a big difference in a lot of ways."

According to Merck Manual, sinusitis symptoms include yellow or green drainage from the nose, pressure and pain in the face, a stuffy nose, bad breath, and coughing up mucus during the day and especially at night. Some people may experience fever and chills as well.

Balloon sinuplasty is a minimally invasive procedure and is often recommended for patients who suffer from chronic sinusitis, after they've exhausted other treatment options. The procedure is fairly straightforward, with few complications reported. Balloon sinuplasty doesn't involve cutting, and there is no removal of bones or tissue during the procedure, according to Healthline.
