Insulin
Expert Insulin Therapy and Diabetes Management by Dr. Anusha Handral
Insulin is a vital hormone that helps the body use glucose (sugar) for energy. It plays a crucial role in maintaining healthy blood sugar levels and ensuring that the body’s cells function properly.
For people with diabetes, the body either does not produce enough insulin or cannot use insulin effectively. In such cases, insulin therapy becomes an essential part of diabetes management.
Dr. Anusha Handral is a highly experienced Diabetes Doctor in Whitefield Bangalore and one of the Best Diabetologists in Bangalore, offering comprehensive insulin therapy and personalized diabetes treatment plans for patients with Type 1 Diabetes, Type 2 Diabetes, and Gestational Diabetes.
What is Insulin?
Insulin is a hormone produced by the pancreas that helps move glucose from the bloodstream into the body’s cells, where it is used as energy.
After eating, blood sugar levels increase, and the pancreas releases insulin to maintain a healthy balance.
Insulin also helps the body:
- Store excess glucose for future energy needs.
- Regulate fat metabolism.
- Support protein synthesis.
- Maintain normal blood sugar levels.
Without sufficient insulin, glucose remains in the bloodstream, leading to high blood sugar levels and diabetes-related complications.
Why is Insulin Important?
Insulin is necessary for:
- Converting food into energy.
- Controlling blood sugar levels.
- Preventing damage to organs caused by high blood sugar.
- Supporting healthy metabolism.
- Maintaining normal body functions.
People with diabetes who do not produce enough insulin may require insulin therapy to prevent serious complications.
Types of Insulin
Different types of insulin work at different speeds.
- Rapid-Acting Insulin
Begins working within minutes and is usually taken before meals.
- Short-Acting Insulin
Helps control blood sugar during meals.
- Intermediate-Acting Insulin
Provides blood sugar control for several hours.
- Long-Acting Insulin
Provides steady blood sugar control throughout the day and night.
- Premixed Insulin
A combination of different types of insulin for convenient blood sugar management.
The type of insulin prescribed depends on your individual needs and lifestyle.
Who Needs Insulin Therapy?
Type 1 Diabetes
People with Type 1 diabetes cannot produce insulin because the body’s immune system destroys the insulin-producing cells of the pancreas.
Type 2 Diabetes
Some people with Type 2 diabetes may require insulin if:
- Blood sugar levels remain uncontrolled.
- Oral medications are ineffective.
- Diabetes complications develop.
- During illness or surgery.
Gestational Diabetes
Some pregnant women with gestational diabetes may need insulin therapy to maintain healthy blood sugar levels and protect the baby.
How is Insulin Taken?
Since insulin is destroyed in the stomach, it cannot be taken as a tablet.
Insulin is usually administered through:
- Insulin injections
- Insulin pens
- Insulin pumps
Your doctor will determine the most suitable method for you.
Benefits of Insulin Therapy
Proper insulin treatment can:
- Lower blood sugar levels effectively.
- Reduce the risk of diabetes complications.

Symptoms of Low Blood Sugar (Hypoglycemia)
Insulin therapy can occasionally cause low blood sugar.
Common symptoms include:

If these symptoms occur, check your blood sugar immediately and consume a quick source of glucose.
Complications of Poorly Controlled Diabetes

Proper insulin therapy helps prevent these complications and improves long-term health outcomes.
When Should You Consult a Diabetologist?
