What is Type 2 Diabetes?

Diabetes is a condition where the body has an impaired ability to produce or respond to the hormone insulin, resulting in an increased level of glucose in the blood. There are various types of diabetes, with the most common being Type 2 diabetes, Type 1 diabetes, and gestational diabetes. Today the most common is Type 2 diabetes, accounting for 85-90% of all diagnosed diabetes.

Most of the carbohydrate food we eat is turned into the simplest molecule of fuel called glucose which is used by cells of the body as a source of energy. The beta cells of the pancreas make insulin which acts as an usher to open cell “doors” and help glucose get into the cells of our bodies.

When you have diabetes, there are either not enough of these beta cells in the pancreas leading to low levels of insulin, or there are enough beta cells but they don’t make enough insulin or the body resists the actions of the insulin and can't use its own insulin as well as it should. Each of these can lead to a relative insulin deficiency. This means that relative to what you need to keep the blood glucose normal, you don’t have enough. If you had enough insulin your blood glucose would be normal and you would not have diabetes.
