Diabetes is a condition caused by uncontrolled blood glucose levels.
High blood sugar levels can damage nerves, blood vessels, the heart and the kidneys.
Damaged blood vessels means less oxygen is delivered to the gums, which increases the risk of gum disease – or periodontal disease – according to Diabetes.co.uk.
Too high blood sugar can also create a breeding ground for bacteria, which may boost the chances of gum disease even further.
“People with diabetes have an increased risk of developing gum disease,” said Diabetes.co.uk.
“Severe gum disease can negatively affect your blood sugar control and increase your chances of suffering from other common long-term complications of diabetes.
“The inflammation, which occurs in the gums, escapes into the bloodstream and upsets the body’s defence system which in turn affects blood sugar control.
“In other words, gum disease and diabetes are linked in both directions.”
In most cases, gum disease isn’t painful, and there are no symptoms of the condition.
But, the disease can cause bleeding in the mouth, swollen and red gums, and persistent bad breath.
Loose teeth and shrinking gums could also be a sign of periodontal disease.
Diabetes patients are also more likely to develop gum disease if they fail to manage their blood sugar properly.
Other symptoms of diabetes include blurred vision, weight loss and genital itching.
You can lower your risk of developing diabetes by eating a healthy, balanced diet and by doing regular exercise.
Getting a good night’s sleep could also lower your risk of developing the condition, according to charity Diabetes UK.
Feeling tired and sleep often makes us want to eat more food, but that raises the chances of uncontrolled blood sugar.
