1 in 10 Americans struggle with diabetes, and more than 90% of them have type 2 diabetes. If left alone, uncontrolled type 2 diabetes can wreak havoc on the body and lead to serious complications. 

What does it mean to have uncontrolled diabetes?

Your body needs protein, fat, and sugar for energy. If the sugar builds up in the blood instead of being used for energy, that sugary blood hurts circulation and causes damage.  Uncontrolled diabetes means your system has been overloaded with with sugar too long. The way we test for this is with an A1c test that shows what percent of sugary blood you have. For most adults with diabetes, uncontrolled diabetes is when your A1c is 7% or higher, according to the American Diabetes Association. An A1c over 9% is often referred to as very poor control. Higher A1c levels increase a person’s  risk of diabetes complications like heart, eye, nerve, or kidney disease. When A1c levels are not safe for your body, you should talk to your doctor about making lifestyle changes or trying another treatment approach to lower blood sugar into a safe range. 

What causes uncontrolled type 2 diabetes?

Uncontrolled type 2 diabetes can be caused by:

  • Not taking medications properly.
  • Not enough medication or other therapies.
  • Eating too many  starchy, or sugary foods (it’s not just the sweet snacks!).
  • Not getting enough exercise. 
  • Undiagnosed and untreated diabetes.
  • Weighing more than your body’s insulin can keep up with
