Why doesn the insulin the body makes work to lower the blood sugar in type 2 diabetes?
First, the pancreas is not able to make enough insulin. The pancreas does make some insulin when you eat, but not enough to keep your blood sugar in normal range. Too much sugar stays in the bloodstream and can not get into the cells. Second, the insulin goes into the blood too slowly to work well. The insulin is not released from the pancreas fast enough to bring the sugar level back to normal within 2 hours after you eat. In type 2 diabetes, the body will also develop a resistance to the insulin that is there. The cells lose some of the insulin receptor sites. When there aren’t enough receptor sites , it does not matter how much insulin is there. The sugar can not get into the cells because there aren’t enough open passageways. This is called insulin resistance. Also your liver stores sugar for times when you don’t eat. The liver will release this sugar between meals and overnight. If the cells in the liver are resistant to insulin, it will release too much sugar. This is one reason
