How Do Genetics Influence Diabetes Causes?
Genetics play a significant role in the development of both Type 1 and Type 2 diabetes, although the influence varies between the two types. In Type 1 diabetes, a person’s genetic makeup can increase their susceptibility to autoimmune attacks on the pancreas' insulin-producing cells. However, not everyone with a genetic predisposition will develop Type 1 diabetes, which suggests that environmental triggers, such as viral infections or other external factors, may also be involved. Researchers have identified several genes associated with Type 1 diabetes, but having these genes does not guarantee the development of the condition.
For Type 2 diabetes, the genetic influence is stronger, especially if there is a family history of the disease. Certain genetic mutations can affect the body's ability to produce insulin or respond to it effectively, making an individual more prone to developing the condition. In addition to genetic factors, lifestyle choices such as diet, physical activity, and body weight play a crucial role in whether someone with a genetic predisposition to Type 2 diabetes will actually develop the disease. While genetics can increase risk, it is often the interaction between genetic predisposition and lifestyle factors that determines the onset of Type 2 diabetes.
