Diabetes has become one of the most widespread chronic conditions in India, affecting millions of people. It occurs when the body is unable to regulate blood sugar effectively, either due to lack of insulin production or because the body cannot use insulin properly. According to Dr Jaspreet Singh, MBBS, MD, DM (Endocrinology) at Ujala Cygnus Group of Hospitals, insulin therapy plays a vital role in diabetes care.
Insulin is a hormone made by the pancreas that helps glucose from food enter cells, where it is used for energy. When this process fails, sugar builds up in the bloodstream, leading to serious health risks. Regular insulin therapy helps prevent these complications and improves overall well-being.
Why insulin is essential in type 1 diabetes
In type 1 diabetes, the body’s immune system mistakenly destroys the pancreas’ insulin-producing cells. As a result, the body cannot produce insulin on its own. Without insulin, blood sugar levels rise dangerously high. For such patients, daily insulin injections are not optional—they are essential for survival. Unlike oral medicines, insulin is the only effective way to control blood sugar in type 1 diabetes.
Why some type 2 diabetes patients need insulin
Type 2 diabetes usually starts with insulin resistance, where cells do not respond well to insulin. In the early stages, lifestyle changes and oral medicines may help. But over time, the body’s ability to produce insulin declines, and medicines may not be enough. At this point, doctors recommend insulin injections to maintain safe glucose levels and prevent long-term complications.
Why insulin cannot be taken as a pill
A common question patients ask is why insulin is not available in tablet form. The reason is that insulin is a protein, and if swallowed, it gets broken down by the digestive system before it can work. That is why it must be injected directly into the body through syringes, pens, or pumps.
Benefits of insulin therapy
Insulin injections help:
- Keep blood sugar within healthy limits
- Prevent kidney, nerve, and vision damage
- Protect the heart from diabetes-related risks
- Improve quality of life
For many patients, insulin is more than just medicine—it is a lifeline that enables them to lead active, balanced lives.
