Insulin is a hormone secreted by the pancreas which helps blood glucose get into our body cells. When there is enough insulin, and our body's signals are working correctly, blood glucose is maintained within normal limits. In people with diabetes, the body is not able to make appropriate use of the food you eat.
Blood glucose stays in the blood instead of going into the cells.
This causes high blood glucose levels which in turn increases the risk for complications, such as heart disease, stroke, kidney disease, blindness, nerve damage to the legs and feet. Unfortunately, people are sometimes diagnosed with diabetes only after complications have been detected. The human body can only function properly with certain levels of sugar in the bloodstream. There are two different types of diabetes Type 1 and Type 2 which are similar in their elevated blood sugar, but different in onset and diagnosis. Type 1 is an auto-immune disease which results in an absence of insulin.
