What Is Insulin?
Man needs energy to work. Human beings get this energy from protein carbohydrates and fatty food. Whatever we eat, that changes in Glucose
and glucose enters the cell where glucose is converted into energy. Insulin determines the pathway for glucose to enter the cell, which is a hormone secreted by the beta cells of the pancreas. Insulin is like a key that opens the cell door.
If our body is low in insulin or not,glucose cannot open the cell door, leading to elevated glucose levels which cause glucose to be collected in the blood which cannot be converted into energy and The level of glucose in the blood rises, causing severe heart, kidney and eye problems. The nervous system is also affected.
When diet and exercise are not sufficient to control blood sugar, and the pancreas unable to produce insulin, the body needs insulin from outside. Many diabetic patients rely on external insulin injections to control their blood sugar.
There are several types of insulin. All insulin helps glucose go into the cell so that glucose can be converted into energy, but they are not all the same. Each insulin type may vary. It depends on how fast insulin works, how long it takes to start working, and how long it takes to control blood sugar, and how long it stays in the body.
At present insulin therapy can be started by any of the following methods like Insulin Injections , Insulin jets, Insulin Infusion Pumps, Insulin Spray, Insulin Nose Spray, Insulin Pulmonary Spray, Oral Insulin Spray.
