Why do people with diabetes experience dry mouth?

As mentioned, dry mouth in individuals with diabetes occurs due to various factors, most of which are related to poor blood sugar control. First and foremost, one of the causes is increased urination.

  • Increased urination can lead to dehydration

On the other hand, since saliva is mostly made up of water and its production changes during this period, it can be said that a lack of saliva is another factor involved, along with changes in the composition of saliva. Besides water, saliva also contains glucose and proteins.

A study published in a dental journal explains that diabetes affects the morphology of salivary glands. It causes the secretion of a substance in the bodies of diabetic individuals that results in the enlargement of the salivary glands and disrupts their function.
