What is Insulin resistance?

Long before a person is given a type 2 diabetes diagnosis, their body starts to undergo noticeable changes. That's good news (you can prevent or delay it if you're at risk) and terrible news (no symptoms mean you won't know you have it). Among the most significant invisible changes? Insulin sensitivity. A major factor in the development of type 2 diabetes is insulin. This essential hormone-without which you cannot survive-controls the body's intricate process of regulating blood sugar, or glucose. The highlights are as follows:
Blood sugar is produced by the breakdown of meals.
When blood sugar enters the bloodstream, the pancreas releases insulin in response.
In order for blood sugar to be utilised by body cells as fuel, insulin facilitates this process.
The liver stores blood sugar for later use in response to signals from insulin.
When blood sugar reaches cells and its levels drop in the blood, insulin is also sent to drop.
Decreased insulin levels cause the liver to release blood sugar that has been stored, ensuring that energy is always available, even after a prolonged period of fasting.
Blood sugar must be transferred into cells as soon as possible since too much of it in the bloodstream might be harmful to the body. Additionally, there is a lot of insulin, which instructs the muscles and liver to store blood sugar. The liver transfers extra blood sugar to fat cells so that it can be stored as body fat once they are full. It's true-weight increase. Even worse, type 2 diabetes and prediabetes are on the horizon. How can one determine whether they are insulin resistant? Your healthcare provider may declare that you have insulin resistance even if no test can detect it if you have high blood sugar, high triglycerides (a type of blood fat), high LDL ("bad") cholesterol, and low HDL ("good") cholesterol. Type 1 diabetes is distinct; it is believed to be brought on by an autoimmune response, in which the body unintentionally assaults itself. Because they cannot produce enough insulin, people with type 1 diabetes must take it in order to survive. The precise origin of insulin resistance is unknown, however being inactive, overweight (particularly around the waist), and having a family history of type 2 diabetes can all increase the risk. It is possible to have insulin resistance without being overweight. Insulin resistance is not something that can be determined by looking at a person.
