If you have wondered about whether diabetes is genetic or not, you are not alone. This is one of the most common questions asked by people who are diagnosed with diabetes, or with parents who have children with diabetes. As you probably already know, there are two type of diabetes, type 1 diabetes and type 2 diabetes. But which type of diabetes is genetic? The answer may surprise you.

Which Type of Diabetes is Genetic?

First of all, there is no true answer to the question of which type of diabetes is genetic. Researchers have found that although there is a predisposition for someone to have a diabetes, there are other factors other than genetics that may trigger the diabetes to occur. The reason is because even though type 1 diabetes and type 2 diabetes has different causes, but there is a bigger chance for both types of diabetes to happen if some family members also have it.

This is evident in the case of identical twins. If one twin get a diabetes, the other one will likely to have it as well, although the possibility differs depending on which type of diabetes it is. Studies show that type 1 diabetes twin will have a 50% chance if the other twin has it. On the other hand, type 2 diabetes twin will have a bigger chance of 75%, if the other twin has it. In other words, 3 out of 4 identical twins will both have type 2 diabetes. However, this is not a true evidence that this is purely genetic, because it is very common in families to share the same lifestyle which is probably causing someone to have type 2 diabetes.

Some examples to support this evidence is, that families who have type 2 diabetes usually share the same lifestyle such as eating habits, exercise habits, as well as being overweight, which has been known to be one of the leading causes of type 2 diabetes.

So to answer the question of which type of diabetes is genetic, the short answer is there is a high probability that type 2 diabetes will have a stronger predisposition to get it, compared to type 1 diabetes. This means that if you have a family member with type 2 diabetes, you have a bigger chance of getting it too if you do not take extra measures in preventing it from happening. This includes proper diet and regular exercise. However, if your family member suffers from type 1 diabetes, your probability of getting it is slightly lower compared to type 2 diabetes.

In other words, there is a predisposition of getting both type 1 and type 2 diabetes, but the type 2 diabetes has a bigger chance to run in the same family. What researchers have not found out is the triggers that might shed a clue to why some identical twins both get it, and some others do not, even though they have the exact same genes.

While we are not sure which type of diabetes is genetic for sure, or what triggers type 1 or type 2 diabetes to occur if you have a family member who suffers from it, the most important thing is to know that prevention is key especially in type 2 diabetes since studies have shown that diet and regular exercise can prevent it from happening, or in some cases reverse the symptoms.
