What causes type 1 and type 2 diabetes?

Type 1 diabetes is caused by genes and environmental factors, such as viruses, that might trigger the disease. Type 1 diabetes occurs when the immune system, attacks and destroys the insulin-producing beta cells of the pancreas and as a result your body does not get the much needed insulin (hormone).

One of the most important myths about the diabetes is eating too many sweets. You are more likely to develop type 2 diabetes if you are not physically active and are overweight. Extra weight sometimes causes insulin resistance and is common in people with type 2 diabetes.

What is insulin resistance?

Insulin resistance is the name given to when cells of the body don’t respond properly to the hormone insulin. The role of insulin is to allow cells of the body to take in glucose to be used.

Type 2 diabetes usually begins with insulin resistance and as a result, your body needs more insulin to help glucose enter cells. When the body becomes resistant to insulin, it tries to cope by producing more insulin. People with insulin resistance are often producing too more insulin than healthy people.
