Diabetes is a chronic condition where your body doesn’t use blood sugar properly. In a healthy body, glucose provides the energy your body needs to function. The hormone insulin helps convert glucose into energy in your muscles and tissues.
When you have Type 1 diabetes, your body doesn’t make insulin. In Type 2 diabetes, your body doesn’t make enough insulin to convert glucose to energy or doesn’t use insulin properly. As a result, your blood glucose levels remain high, which can cause a number of serious health problems, including heart disease, nerve damage, and organ failure.
You can also have a condition known as prediabetes, where your blood glucose levels stay high, but not high enough to be considered diabetes. In many cases, people with prediabetes develop Type 2 diabetes if they don’t change their diet and eating habits.
