How Does Insulin Lower Blood Sugar There are three types of situations that require insulin injections

Insulin injections are a very effective way to treat diabetes quickly, but what is the reason for this? Let's take a look at how insulin lowers blood sugar, and we should also understand what situations insulin injections are necessary.

How insulin lowers blood sugar

Insulin is like a "key", and there are many small structures on the surface of tissue cells in the human body that specialize in receiving insulin, called receptors, like a "lock". When the two are combined, the "door" for glucose to enter the cell is opened, and the glucose in the blood enters the cell, causing the blood sugar to decrease.

The glucose that enters the cell goes through a series of complex processes to produce "energy" that is used by the body. The other part is stored as "energy" in the liver, muscle, and fat to be used when needed.

The level of glucose in the blood of a normal person and the amount of insulin secreted are properly coordinated, so that the blood sugar can remain stable and will not be too high or too low. However, in the following two cases, glucose in the blood cannot enter the cells, so it accumulates more and more in the blood

When is insulin necessary?

1. First of all, type 1 diabetes should be treated with insulin, because the onset of type I diabetes is because its islet secretion function is gone, there are almost no islet cells, and they can't secrete insulin, so they must be treated instead.

2. Patients with type 2 diabetes should use insulin when oral hypoglycemic agents fail, and the failure of oral hypoglycemic agents generally refers to insulin secretagogues, such as yellow ureas, and now there is a kind of urea.In the past, we thought that astraurea drugs, such as Youxia, Damekang, Mepida, and Glucose, should be insulin if they use 6 tablets, which means that our pancreatic islet function is too exhausted.

3. The third is that some people with serious complications of diabetes or other serious diseases should be treated with insulin. For example, if our diabetic patients already have kidney disease, or renal insufficiency, or eye lesions are more severe, or other lesions are also more severe, this should be treated with insulin. Or if you have other serious diseases, such as pneumonia, or heart rate failure, or some other endocrine disease, these three types of people must be treated with insulin.
