Insulin a hormone needed for effective conversion of glucose into energy, keep as active, and maintain the blood-glucose level.
What are Insulin functions?
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, the pancreas secretes Insulin. Body cells have insulin receptors, which bind the insulin, which is in the blood circulation. The cell with insulin attached can absorb sugar glucose from the blood stream and burnt it for energy.
In people who do not have diabetes, the body makes the right amount of insulin on its own. However, diabetes requires certain quantity of insulin throughout day and night.
Insulin and type 1 diabetes
If no insulin, you can eat food and still in a state of starvation since, the cells cannot be able to absorb glucose without insulin. This is the reason for Type 1 diabetic (no or insufficient insulin secretion) can become very weak without insulin shots. The type 1 diabetic’s has deficiency or no insulin secretion, so they must have it replaced via artificial insulin.
Insulin and type 2 diabetes
Type 2 diabetes is commonly had been high blood-glucose, because of insulin resistance not insulin deficiency. Mostly, in the case of type 2 diabetes, the level of insulin in the blood is slightly higher than, a non-diabetic. Insulin resistance means the body cells not to respond properly or sluggish to the insulin and thus cannot consume enough glucose. This leads to high blood-glucose level than normal. Treat type 2 diabetes, mostly with oral medicine and rarely do they need insulin shots.
