What’s the Difference Between Type 1 and Type 2 Diabetes?
Diabetes is one of India’s fastest-growing health concerns, with more than 100 million people currently living with the condition. Yet many patients still do not understand the difference between Type 1 and Type 2 diabetes, two conditions that may sound similar but work very differently inside the body.
Whether you are newly diagnosed, caring for a family member, or simply educating yourself, this guide explains key differences, symptoms, causes, treatment options, and prevention methods in the simplest way possible.
What Is Type 1 Diabetes?
Type 1 diabetes is an autoimmune disease. The body’s immune system mistakenly attacks the insulin-producing cells in the pancreas, leaving the body with little or no insulin.
- Usually diagnosed in children, teenagers, or young adults
- Not caused by diet or lifestyle
- Requires lifelong insulin therapy
- Cannot be prevented
- Symptoms often appear suddenly
People with Type 1 diabetes must take insulin daily through injections or an insulin pump. With proper care and monitoring, they can lead healthy, active lives.
What Is Type 2 Diabetes?
Type 2 diabetes is the most common form of diabetes in India. It develops when the body becomes insulin-resistant or does not produce enough insulin.
- Usually develops in adults over 40, but now seen even in younger adults and children
- Strongly linked to unhealthy diet, physical inactivity, obesity, stress, and family history
- Managed with diet, exercise, oral medicines, and sometimes insulin
- Often preventable through lifestyle changes
- Develops slowly, sometimes without noticeable symptoms
Due to late diagnosis in many cases, it may go unnoticed for years unless regular screening is done.
Type 1 vs Type 2 Diabetes: Key Differences
Here’s a quick comparison to help you understand how these two types differ:
| Feature | Type 1 Diabetes | Type 2 Diabetes |
| Usual Age of Onset | Childhood or adolescence | Adults over 40, but increasingly younger |
| Cause | Autoimmune destruction of insulin cells | Insulin resistance or poor insulin production |
| Insulin Production | Very little or none | Often reduced or not used effectively |
| Treatment | Always needs insulin | Diet, exercise, tablets, insulin (if needed) |
| Can it Be Prevented? | No | Often, through lifestyle changes |
| Speed of Onset | Sudden | Gradual |
| Prevalence in India | Less common (~5–10%) | Very common (~90% of diabetes cases) |
Symptoms of Diabetes to Watch For
The symptoms of diabetes can be subtle or severe. If you notice any of the following, it’s time to see a doctor:

- Feeling very thirsty
- Frequent urination
- Fatigue or weakness
- Unexplained weight loss
- Blurred vision
- Slow-healing wounds
- Repeated infections or itching
- Tingling or numbness in hands or feet
Early diagnosis can prevent complications such as heart disease, kidney damage, nerve issues, and vision problems.
