What Does Bad Breath Have To Do With Diabetes?

Bad breath could be a sign of a more serious health problem. Breath has an extraordinary potential to reveal information about your general health. Halitosis is the medical term for unpleasant breath generally.

Ammonia-smelling breath, for example, is frequently linked to kidney illness. Do you have rotten fruit-scented breath? This could be a symptom of anorexia nervosa.

Other medical illnesses can also affect breath odour like lung cancer, liver problems, cystic fibrosis, and asthma.

Many persons with Diabetes have a fruity, sweet odour to their mouth or a chemical stench to their breath. In reality, infrared breath detectors can identify prediabetes or early stage diabetes since it is so frequent.

What is the reason behind this?

There are a few things that lead to foul breath in individuals with Diabetes. Periodontal problems, ketones, dry mouth, and the increased risk of infection linked with diabetes are just a few of them.

Periodontal disease

Gingivitis, minor periodontitis, and severe periodontitis are examples of periodontal disorders, commonly known as gum diseases.

Bacteria assault the tissues and bones that support your tooth in these chronic illnesses. In addition, inflammation can affect your metabolism and raise your sugar levels, making diabetes severe.

Diabetes can cause periodontal disorders, but it can also cause additional issues for people with diabetes. For example, it is connected to heart attacks and strokes, both of which can be consequences of diabetes.

Diabetes can cause an increase in glucose levels in the mouth, which can lead to bacteria development, infection, and foul breath.

When blood sugar levels are high, it hampers the body’s ability to fight infections, making gum healing more difficult. As a result, periodontal disease in people with diabetes can be more severe and take more time to recover than in individuals without diabetes.


When your cells are starving because of glucose, they start burning fat as a source of energy. Ketones, a kind of acid produced by the liver, are formed as a consequence of the fat-burning mechanism. Ketones have a smell that is comparable to that of acetone.

This form of bad breath isn’t exclusive to people with Diabetes. It’s also a common symptom of the “keto” diet, which is low in carbs and high in protein. The fragrance of diabetic ketoacidosis, on the other hand, is significantly more robust.

We must consider ketoacidosis in order to fully comprehend the link between Diabetes, ketones, and smelly breath.

When your ketone levels are exceedingly high, it could be due to a lack of insulin, a lack of food, a lack of blood glucose, or a mixture of all three. 

The longer it goes on, the more probable someone will develop diabetic ketoacidosis (DKA). If you see any of the signs of DKA, visit a doctor right away. DKA is exceedingly severe and, if left untreated, can be deadly. 

The following are some of the most prevalent diabetic ketoacidosis health conditions:

  • Breath that stinks like acetone or fruits
  • Urination is becoming more frequent.
  • Puking and dizziness
  • Pain in the abdomen
  • Blood sugar levels that are too high
  • Breathing problems
  • Confused
  • Parched or irritated skin.

Is it possible for diabetes medications to create bad breath?

Metformin is a diabetes medicine that helps persons with type 2 diabetes manage their blood glucose levels. Metformin users frequently complain about a nasty aftertaste.

If you suspect that metformin is causing your bad breath, talk to your doctor about finding different treatment.
