Causes of prediabetes
The exact causes of diabetes are unknown. What is clear is that people with prediabetes don’t process sugar (glucose) properly anymore. As a result, sugar builds up in the blood instead of doing its normal job of giving energy to the cells that make up muscles and other tissues. Most of the glucose in your body comes from the food you eat. When your food is digested, sugar enters your bloodstream. Moving sugar from your bloodstream to your body cells requires a hormone called insulin.
Insulin comes from a gland located behind the stomach called the pancreas. Your pancreas sends insulin into your blood when you eat. As insulin circulates, it allows sugar to enter your cells and lowers the amount of sugar in your blood. When your blood sugar level starts to drop, the pancreas slows the secretion of insulin into the blood. They primarily consist of:
- Increased metabolic disturbance as a result of both worsening hyperglycemia [2] and insulin resistance.
- Insulin resistance, which occurs when cells do not respond properly to insulin.
