2What causes higher blood glucose levels?
There are certain cells in our body which release a hormone called INSULIN. This hormone regulates glucose levels in the blood. After we take meal, the level of this hormone increases and it regulates the uptake of glucose by the tissues including skeletal muscles and adipose tissue.
The excess glucose is converted into glycogen which is its storage form and is stored in the liver until next time our body needs glucose. All of these events occur and maintain the blood glucose levels within the normal range.
Any disturbance or abnormality in the function of insulin results in abnormally high blood glucose levels, a condition called diabetes.
