Yes, one of the main causes of diabetes is inherited. This is the most straightforward answer to the question: Is diabetes hereditary?
More than 80 percent of patients yearly have at least one family member with the same health threat. However, most relatives never develop the disease. This is because the inherited characteristic that causes diabetes is a recessive quality. It means that someone must obtain two copies, one from each parent, to become really prone to the disease. If a person obtains only one bad inherited characteristic, they might not have the disease.
Diabetes is the result of a genetic disorder; symptoms seldom grow before the 50’s. Among those who have inherited the genetic disorder, nearly 21 percent of the people will develop the disease while juvenile diabetes occurs in less than five percent people. Even in people with the hereditary characteristics for the disease, many other factors are also found like age, gender and obesity. Diabetes hardly ever develops in the youth and is much more common among people in the forties. Likewise, women are more at risk to the development of diabetic symptoms. However, despite all this, the ugly truth is that most diabetics are diagnosed when they are flabby.
The painful reality is that diabetes cannot be cured, but it can be treated effectively to enable the diabetics to lead normal lives. Furthermore, diabetes results from both hereditary and environmental factors. These environmental factors are categorized as "lifestyle factors" - what and how much the individual eats and how much he or she works out.
As mentioned above, there is a genetic component to the diseases which may or may not be inherited. However, surprisingly, most diabetics of whatever type do not have a first degree relative with the same disease. It is true that the genetic tendency to diabetes is quite easy to occur. However, there are many other equally significant contributing factors and the probability that you will get the disease or not depends whether the bad genetic factors that are inherited are the dominant ones or the recessive ones. There are also some genes that prevent the disease.
In one case, a certain family member once asked, “Everyone in my family has diabetes. Even though I live a healthy lifestyle is it inevitable that I will develop diabetes later in life? So, is diabetes hereditary to the extent that nothing can be done about it"?
The reply is stated here. “The short answer is no, it is not inevitable that you will develop diabetes later in life. The exact cause of both Type 1 and Type 2 diabetes is still unknown. However, you do have a greater risk of getting the disease".
According to the American Diabetes Association, if the father is suffering from Type 1 diabetes, the probability of a child getting same health ailment is 1 in 17 and that changes to 1 in 25 if the mother has the problem and the child was born before she was 25 and it again changes to 1 in 100 if the child was born after she turned 25. On the other hand, If one of the parents was diagnosed with Type 2 diabetes before the middle age, the child’s risk in getting same health threat would be 1 in 7. The risk decreases to 1 in 13 if the parent was diagnosed after 50 years of age.
Bear in mind that although genetic inclination is a dangerous factor for both types, it is just one risk contributing factor. It is obvious that lifestyle factors like obesity and lack of exercise are significant danger elements for Type 2 diabetes. Therefore, exercise regularly and maintain ideal body weight. In this manner, you will be making a positive impact towards minimizing the threat even if diabetes is hereditary.
