Diabetes causes you higher blood-glucose levels, which also affects how much glucose is in your saliva. You have to take extra care of your gums and teeth to keep the rot and decay away. Floss and brush regularly, and make sure to see your dentist twice a year for cleaning.
An easy way to reduce your risk of contracting diabetes is to get up and get active. People who take an hour long brisk walk daily will reduce their risk of contracting diabetes by over 35%. Even when you cannot walk for an hour a day, do what you can to get moving like take the stairs instead of the elevator, park at the furthest parking spot at the grocery store, or take two or three trips in carrying in the groceries.
