What is the main reason for insulin is not screting more to digest glucose in our body.
Glucose levels are tightly controlled by insulin so that the rate of glucose production by the liver is matched by the rate of use by the cells. In diabetes, hyperglycemia means that the loss of glucose through the urine is also needed to achieve this balance.3
In healthy individuals, the role of insulin is to keep a steady blood glucose level by ensuring sufficient release from the liver. Low insulin levels cause the release of glucose while more insulin inhibits glucose production by telling the liver to store glucose as glycogen.3,5
The importance of insulin for maintaining blood glucose levels is mainly due to this effect on liver storage and release. The uptake of glucose by cells can take place without insulin - the hormone simply accelerates this uptake through recruitment of glucose transporter molecules to the cell membrane.3
If there is a lack of insulin in the liver, the liver releases glucose into the bloodstream faster than tissues can metabolize it.
