What Causes Diabetes?

Understanding the causes helps you take control early.

What’s happening in the body?

Diabetes develops when your body cannot properly control blood sugar (glucose).

This usually happens because:

💡 Insulin acts like a “key” that allows sugar to enter your cells for energy.

Main Types of Diabetes

Type 1 Diabetes

The body does not produce insulin. This is usually diagnosed earlier in life and requires insulin treatment.

Type 2 Diabetes

The most common type. The body becomes resistant to insulin or doesn’t produce enough. Often linked to lifestyle and ageing.

Common Causes & Risk Factors

⚖️ Excess weight

Especially around the abdomen, which increases insulin resistance.

🏃 Low physical activity

Less movement makes it harder for your body to use glucose effectively.

🧬 Family history

Genetics can increase your risk, especially for type 2 diabetes.

🎂 Age

Risk increases as you get older.

🥗 Unhealthy diet

High intake of processed foods and sugars contributes over time.

🩺 Other health conditions

Such as high blood pressure or high cholesterol.

⚠️ Diabetes usually develops gradually — small changes early can make a big difference.

Key Takeaway

While some risk factors (like age or genetics) cannot be changed, many can be improved through lifestyle.

💡 Focus on what you can control — movement, diet, and habits.
