6 Causes of Bad Breath and Its Underlying Reasons


Bad breath, medically called halitosis, can result from poor dental health habits, types of food one eats, unhealthy lifestyle habits or even can be a sign of other health problems.

The most common way of addressing the issue of Bad breath is by maintaining a Good Oral Hygiene. But if regular brushing, flossing and mouthwash isn’t helping with the problem then surely seeking a professional help is necessary. Just like other common symptoms of diseases, bad breath can also be a symptom for some very serious underlying health problems.

Here are the most common 6 health issues that can be identified through the kind of Bad breath one has.

Gum Disease

If your breath has a metallic smell, you might have bacteria growing under your gum line — that can lead to inflammation and even infection. This condition is called periodontitis. It’s more likely to occur to those who smoke or don’t brush and floss regularly.

Acid Reflux

This condition makes stomach acid flow the wrong way, back into the esophagus – that connects your throat to your stomach. It can give your breath a sour smell. The acid also can damage the inner lining of the throat and mouth which makes it a breeding ground for bacterias.


If you have this condition, fruity breath can be a sign that your body is using fat for fuel instead of sugar (glucose). That probably means you’re running very low on the hormone insulin, and you should call your doctor.

Respiratory Infections

Colds, coughs, and sinus infections can send mucus filled with bacteria through your nose and mouth. That can affect your breath. It usually goes away once you get over your cold.


When your body doesn’t have enough water, you may not make enough saliva, which normally cleans bacteria out of your mouth. That can lead to not-so-fresh breath. Conditions that affect the glands that make saliva — like Sjögren’s syndrome and scleroderma — also can cause dry mouth and bad breath.

Kidney Failure

You may have “fishy” breath if your kidneys can’t get rid of waste like they should. It’s most common in the last stages of kidney failure, known as end-stage renal disease (ESRD). When it gets to this point, it’s usually treated with a machine that helps filter your blood (called dialysis) or a kidney transplant.
