Introduction to Diabetes

Last updated on May 10th, 2022

Food we eat is broken down into fuel called Glucose. Glucose enters the bloodstream and travels to the cells to be used as fuel. Glucose needs help pf hormone called Insulin to enter the cells. Insulin is produced by gland in body called pancreas.

What is Diabetes?

Diabetes is a metabolic disease that causes blood glucose (sugar) levels to rise higher than normal

Diabetes can be classified into the following general categories:

Type 2 diabetes is the most common form of diabetes.

 

If you have Type 2 diabetes your body does not use insulin properly. This is called insulin resistance. Whereas in Type 1, insulin is not produced by pancreas.

Gestational Diabetes is during pregnancy.

The cells become starved for energy, which can leave you feeling tired and rundown. Type 2 is treated with lifestyle changes, oral medications (pills), and insulin. Some people with Type 2 can control their blood glucose with healthy eating and being active. But, your doctor may need to also prescribe oral medications or insulin to help you meet your target blood glucose levels in desired levels to remain healthy.

HbA1C

The A1C test measures your average blood glucose for the past 2 to 3 months.

Diabetes is diagnosed at an A1C of greater than or equal to 6.5%.

If blood glucose level is not controlled, blood vessels throughout the body may become diseased.

Prolonged high blood glucose affects all organs and nerves. As a result, the risks to the heart, kidneys, eyes and limbs are increased.
