Insulin

Insulin a hormone needed for effective conversion of glucose into energy and keep as energetic and maintain blood glucose level.

Insulin is a hormone (a protein) secreted by groups of cells within the pancreas called islet cells. Food digested and glucose is absorbed from the intestines into the bloodstream after a meal. With respect to the glucose level in blood, Insulin is secreted by the pancreas. Body cells have insulin receptors which bind the insulin which is in the blood circulation.  The cell with insulin attached has the ability to absorb sugar glucose from the blood stream and burnt it for energy.

In people who don’t have diabetes, the body makes the right amount of insulin on its own. But in case of diabetics, certain quantity of insulin is needed throughout day and night.

If no insulin, you can eat food and still in a state of starvation since the cells cannot able to absorb glucose without insulin. This is the reason for Type 1 diabetics (no or insufficient insulin secretion) can become very weak without insulin shots. The type 1 diabetics have deficiency or no insulin secretion, so they must have it replaced via artificial insulin.

Type 2 diabetes are commonly have high blood glucose because of insulin resistance not insulin deficiency. For type 2 diabetics the levels of insulin in the blood are even a little higher than a non-diabetic. Insulin resistance means the body cells not respond properly or sluggish to the insulin and thus cannot consume enough glucose. This leads to high blood glucose level than normal. Mostly type 2 diabetics are treated with oral medicine and rarely do they need insulin shots.
