Our body uses the glucose with the help of insulin, which is synthesized in the pancreas and acts on the cell receptors, so that glucose gets entry into the cell for consumption. Diabetes is a disorder in which body is not able to use the glucose efficiently.
Once diabetes was considered as a disease of rich people, but nowadays it is seen in all classes of general population. One of the major causes of type 2 diabetes mellitus is wrong eating habits.
Foundation Period of Diabetes:
Just after the infancy period, mothers starts giving sweet products to their kids. The children become used to sweets and products high in sugar. It is seen that this is the time from which pro-glucose imbalance starts settling in the form of frequent insulin fluctuations and is the foundation period of diabetes mellitus type 2.
Role of Insulin:
When a food product is consumed, it is initially absorbed by GIT system. Then it reaches the blood and through which it will be available to pancreas and so insulin is secreted. Here, it is important to understand that in the blood there is always a constant amount of insulin. It is known as base levels of insulin. In response to food products it peaks in few hours and return back to base level in approximately 3 to 4 hours after consumption of food.
For a healthy metabolism, the insulin should reach to normal base levels after meals. But, unfortunately insulin hardly comes to base levels in most of the people nowadays, because they eat so frequently. Here, meal means everything which is eaten except plain water. Even a cup of tea is a meal, because it will cause a spike in insulin level. Ideally a person should eat three times a day and there should be a gap of at least 5 to 6 hours between meals, so that insulin could reach to normal base levels.
If a person keeps following frequent intake of meals, which causes hyperinsulinemia and at the same time the person is not so much physically active, then the blood sugar is not used. Also, we can say that it is not required by the cells and remains in blood causing hyperglycemia. As a result, our smart body starts down regulation of insulin receptors, which means a decrease in the number of insulin receptors. So, down regulation of insulin receptors occur as a result of inactivity and a sedentary lifestyle.
As the number of insulin receptors decreases, there is hyperglycemia in blood and most of the times for a sustained period after meals which is simply the starting phase of this disorder. This decrease in insulin receptors is a reversible condition for few years. If a person starts doing exercise in this phase, then again a phenomenon of up regulation is possible in which the normal number of receptors is restored in response to exercise. But, if the down regulation of insulin receptors remains as such for a few years, then permanent loss of receptors occurs and diabetes gets settled into body.
Why Diabetic People Always Feel Hungry?
People who are having high levels of insulin often feel hungry and keep eating. In our body there are two hormones, one is to start hunger and the other is for satiety. They are ghrelin and leptin respectively. Insulin is structurally similar to leptin. So, if a person having frequent high levels of insulin, then this insulin blocks those receptors in central nervous system on which usually leptin works and satiety is not felt. As a result a person does not feel satiety and eats more and produces more insulin, which again produces more hunger by not getting satiety. So, it is a vicious cycle which is very dangerous for the metabolism and is a main part in diabetes mellitus 2.
How to Prevent Diabetes?
As a preventive value I would emphasize that a person who is prediabetic still or is healthy,
The above mentioned two things are important in preventing type 2 diabetes mellitus.
