When the blood sugar levels in the body get too high, a common disease known as diabetes can occur. The body relies on the pancreas to produce insulin, a substance that converts glucose to energy for the body’s cells. Without sufficient insulin, glucose can remain in the body and build up to unhealthy and even dangerous levels. Type 1 diabetes occurs when the body fails to produce any insulin at all. Type 2 diabetes, the more common type, occurs when the body still produces insulin but not enough. Obesity and a high sugar intake can contribute to type 2 diabetes, although not everyone with type 2 diabetes is overweight. Left untreated, diabetes can lead to blindness, kidney disease, and nerve damage. Read more about diabetes or visit our online drug catalog to fill your prescription.
