Cause of 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 has 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. Among people of Hispanic ethnicity, Mexicans had the highest prevalence (13.8%), followed by Puerto Ricans (12.0%), Cubans (9.0%), and Central/South Americans (8.5%)
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.
