What is the Function of Insulin in the Human Body?
Insulin helps in the metabolism of the body and without this hormone, we cannot live.
It depresses blood glucose levels in different ways including glycogen synthesis and increasing the cell consumption of glucose. It also stimulates the conversion of glucose into proteins and lipids, which reduces the level of glucose.
Insulin also inhibits the hydrolysis of glycogen (the breakdown of glycogen into glucose using water) in the liver and muscles.
1. Insulin action on Digestive System
When we eat something it goes straight into the stomach and then goes through various digestion processes. The food is converted into small particles and absorbed by the blood. If the food contains carbohydrates then the pancreas secretes the insulin to make use of them for cellular metabolism.
The excess glucose is stored in different parts of the body like muscles, liver and is used by the body when needed. (1)
In this way when we eat, insulin keeps our glucose level in a normal range.
2. Insulin and Circulatory System
Our circulatory system makes sure that everything in the body goes well. When there isn’t enough insulin in the blood then glucose gets back into the bloodstream from the storage cells. This increases the glucose level in the body which could cause diabetes and nervous disorders if the level exceeds the normal range.
On the other hand, if there is insulin in the blood then it maintains our glucose level and everything performs well.
In this way, our circulatory system ensures the proper amount of insulin when needed.
What if Insulin does not Function Properly?
There are 2 types of failures:
1. Failure of Insulin Production
Failure of this hormone causes a condition called Diabetes Mellitus. The symptoms of this disease are, high level of blood sugar in the urine, a disturbance of the body’s osmotic equilibrium and derangement of the nervous system.
2. Excess of Insulin Production
If excess insulin is produced, the utilization of sugar in the body will be too high and its level falls in the blood (hypoglycemia) which upsets nerve and muscle functioning.
The Bottom Line!
The proper functioning of Insulin in the human body is very important for survival. If you want things to function properly then you must take some precautions:
- Avoid excessive use of Cold Drinks
- Do Regular Exercise
- Keep a balance in diet
- Avoid too much use of Alcohol
- Stop Smoking
- Eat vegetables and fruits
- Keep Body Weight normal
