Cause of type 2 diabetes

Although the cause of insulin resistance is yet to be found, it is known that it is affected by behavioural risk factors being triggered by the environment.

There are several factors that come into play when discussing the cause of type 2 diabetes. Unlike Type 1 diabetes, the chances of developing type 2 diabetes are very much affected by behavioural risk factors.

Risk factors causing type 2 diabetes

Age: Simply put, your chances of developing type 2 diabetes increase with age. Not uncommonly, you gain weight when you get older and weight can play a big part in developing type 2 diabetes. Usually type 2 diabetes is seen in individuals over 40, but in recent years it has started to develop earlier.

Genetics: If you have a parent or sibling with type 2 diabetes, you are at a greater risk of developing it too. The risk depends on how direct the line to the relative is. If one of your parents have type 2 diabetes, you will have a one-in-three chance of getting it too.
Ethnicity: Ethnicity can play a role and it is seen that African Americans, Latinos, Native Americans and Asian Americans / Pacific Islanders hold a bigger risk of developing type 2 diabetes. It is seen 6 times more often in South Asian areas than in the UK
Inactivity and unhealthy lifestyle: Obesity and unhealthy living are some of the major risk factors in the development of type 2 diabetes. Exercising is necessary for a healthy weight loss and not only is it good for the body to move, exercise benefits the blood glucose levels and improves glycemic control. If you have pre-diabetes exercise can prevent the onset of type 2 diabetes and if you already have it, exercise can help your body to produce insulin.
