Type 2 diabetes can be hereditary. It means it comes with genes. This does not mean that you will have diabetes if your father or mother has it. However, you have more risk if your father or mother has diabetes.

Genetic mutation is a risk factor of type 2 diabetes. But it is not a high risk. Anyway, you have to be in concentration on it more than the other people should.

  • Asian Americans
  • Alaska natives
  • American Indians

Lifestyle issues of type 2 diabetes causes

According to the fact that lifestyle issues hold a major part in type 2 diabetes causes. These are the most discussing and most preventable causes.

Lack of exercise

Most of the people have very busy life schedules. Therefore they have no time to get even a relaxation. Some people work on a desk and long hours without moving. Sitting jobs are the most responsible lifestyle issue cause for type 2 diabetes.

So, if you are such worker, make a thorough concentration on moving. It means you have to get exercises in the morning or in the afternoon. At least a 30 minute exercise schedule per day is enough to get out of the diabetes risk.

Taking most of the meals outside means a high risk of type 2 diabetes. Meals purchasing from restaurants or hotels are the outside meals we mentioned. Most outside meals have more carbs, fats, sugar and salt. It is because vendors do not concern about the health and they only concern about the taste. High amounts of carbs, fats and sugar creates a risk on type 2 diabetes.

Meanwhile some people have unhealthy eating habits. Most of them addicted to sugar. Therefore they eat more sugary foods a day. This will also drive them to a diabetes risk.

Most of the fast foods are also in the same category. Carbs, fat, sugar and salt are high in fast foods. People who addicted to several snacks per day also meet the diabetes risk.

Therefore, you should take healthy meals every time. In addition, avoid unhealthy eating habits to prevent diabetes.

Obesity or excess body weight

In the previous two type 2 diabetes causes, we discussed about lack of exercise, unhealthy eating habits and unhealthy meals. These two causes for the obesity too.

So, how does the obesity causes for type 2 diabetes? Some researches shows that obesity increase the insulin resistance of body cells.

Finally we can assume that all of the above three facts are linked each other.

How does the insulin resistance come in type 2 diabetes causes?

Insulin resistance is the most common factor in type 2 diabetes causes. What is insulin?

Insulin is a hormone. It is essential to absorb glucose from blood to cells. Therefore the insulin amount is an essential factor in diabetes.

Women can suffer diabetes when they get pregnant. Even if they did not have diabetes before as well. This type of diabetes is the gestational diabetes. According to the scientists this is due to the hormone change during pregnancy.
