Importance Of Insulin

3 November, 2025

Introduction

Importance of Insulin lies in its vital role in helping the body use glucose for energy. The human body gets glucose from food every day, but it can utilize that glucose only when insulin functions properly. This essential hormone controls blood sugar levels and ensures that every cell receives the energy it needs to work efficiently.

What

Insulin is a hormone that is produced by the pancreas.It helps the glucose present in the blood enter the cells and produce energy. If insulin does not work properly,the blood sugar level increases, resulting in diabetes.

How to work

After eating, the blood glucose level increases.Then the pancreas quickly releases insulin.This insulin allows the glucose to enter the cells, so that the body gets energy.In this way, insulin maintains the balance of blood sugar.When the body cannot produce enough insulin, glucose accumulates in the blood. If this condition continues for a long time, diabetes occurs.

Types of insulin

There are three main types of insulin currently used in medicine:

Rapid-acting insulin – starts working quickly, short-lived.

Intermediate-acting insulin – works slowly, has a long-lasting effect.
Long-acting insulin – controls blood sugar levels throughout the day.

Why needed

In type 1 diabetes, the body cannot produce insulin at all. So the patient has to take insulin through injections.

In type 2 diabetes, the body produces some insulin, but it is not effective. In that case, the doctor prescribes insulin.

Insulin not only helps the body use glucose, it also maintains the proper functioning of the heart, brain and muscles.

Precautions

Take the dose of insulin as advised by the doctor.

Change the place before each injection.

Monitor blood sugar.

Never change the dose on your own.

Conclusion

Importance of Insulin goes beyond its medical use — it supports life itself. Regular insulin use, along with a balanced diet and daily exercise, helps diabetics maintain good health. Understanding how insulin works and using it correctly ensures stable blood sugar levels and a healthy, active life.
