What is the main cause of diabetes?

There are different leading causes for the two major types of diabetes:

Type 1 Diabetes:
The leading cause is an autoimmune reaction where the body's immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. This autoimmune process is likely triggered by genetic susceptibility and unknown environmental factors, but the exact cause is still being researched.

Type 2 Diabetes:
The leading causes are:

1) Insulin resistance - The body's cells become resistant to insulin, impairing their ability to use insulin effectively to regulate blood sugar levels.

2) Relative insulin deficiency - The pancreas cannot produce enough insulin to overcome insulin resistance.

The primary risk factors that contribute to developing type 2 diabetes include:

- Obesity and being overweight
- Poor diet and lack of physical activity
- Increasing age
- Family history and genetics
- Ethnicity (higher risk in certain ethnic groups)
- History of gestational diabetes
- Polycystic ovary syndrome (PCOS)

While genetics play a role, the majority of type 2 diabetes cases are caused by modifiable lifestyle factors like poor diet and lack of exercise that lead to obesity and insulin resistance over time.
