Insulin
| Diabetes Insulin
Insulin a
hormone needed for effective conversion of glucose into energy and keep
as energetic and maintain blood glucose level.
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, 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.
Insulin and
type 1 diabetes
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.
Insulin and
type 2 diabetes
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.
