Type 1 diabetes is a condition in which your pancreas does not make or makes very little insulin. Type 1 diabetics are not able to produce insulin because their bodies attack insulin-producing cells. Without insulin, blood sugar cannot get into the body’s cells and builds up in the bloodstream. Type 1 diabetes is known as insulin-dependent or juvenile diabetes.
Your body breaks down most of the food you eat into glucose (sugar) and releases it into your bloodstream. When your blood sugar rises, it signals your pancreas to release insulin. Insulin acts like a key, letting the blood sugar into your body’s cells to use as energy.
Over time, diabetes can lead to serious health conditions like heart disease, vision loss, and kidney disease.
