7 Things That Your Breathing Tells You

Your breath also tells you something. It’s most likely down to something you ate or because you haven’t brushed your teeth properly, you’d think. Doctors said, almost all bad breath odours are caused by anaerobic bacteria living in the back of the tongue, throat and tonsils, which break down the proteins in our food as part of their daily job. Here are few diseases that your breath indicates.


One of the tell-tale signs of undiagnosed Type 1 diabetes is the faint smell of pear drops, or ammonia, on the breath. This occurs because a lack of insulin means the body can’t use sugar for energy and starts to break down the fat instead. Waste products called ketones build up and are exhaled.


People who are suffering from sinus problems often emit a scent reminiscent of mothballs. This is because the mucus formed when you have a stuffy nose or congested throat contains very dense proteins. It is these proteins, which are hard for the body to break down, that contain that very distinctive odour.


High-protein, no-carb diets can leave you with foul-smelling breath. Again, as with diabetes, it’s those ketones that are to blame. As the body has fewer carbs to turn into energy, it begins to burn fat and proteins. In this instance, the proteins consumed from a no-carb diet produce this unpleasant smell.


When tonsils are infected and inflamed, it makes it difficult for the anaerobic bacteria at the back of the tongue to break down chemicals as usual. Sulphur-producing bacteria breed deep in the tonsils, and the infected ones can’t break it down. It’s this sulphuric smell that makes the breath smell so bad when someone is suffering from tonsillitis or tonsil stones. In rare cases, this smell could also indicate cirrhosis of the liver.


No one’s mouth smells as fresh as a daisy when they wake up, but if normal brushing doesn’t alleviate the problem, then there might be another underlying cause. Some people suffer from Xerostomia, or dry mouth, where the saliva isn’t flowing as it should. A lack of saliva can cause bacteria to build up, leading to bad breath.

Nitrogen is the main culprit when it comes to giving out fishy smells. If your breath has a fishy odour, your kidneys might be to blame. If your kidneys are not functioning properly, there will be a build-up of nitrogen.


Rotting tissue can mimic the smell of faeces because of the production of chemicals by anaerobic bacteria. The number-one infection in modern humans is infected gums. So the smell of faeces can just as easily come from a lack of flossing as from a blockage in the bowel.
