Genetic Predisposition Testing for Type 2 Diabetes

Type 2 diabetes is the most common form of diabetes, and occurs when the pancreas does not produce enough insulin, or the body is not able to metabolise the insulin properly, a process called insulin resistance. Insulin is the hormone responsible for regulating glucose levels in the blood. This will lead to elevated levels of insulin in the blood. Type 2 diabetes tends to develop slowly, and a person may be unaware that he or she has type 2 diabetes.

Signs and Symptoms:

  • Increased thirst and frequent urination.
  • Increased hunger
  • Weight loss
  • Fatigue
  • Blurred vision
  • Slow-healing sores or frequent infections

What causes Type 2 Diabetes?

Type 2 diabetes can arise from and be exacerbated by obesity, hypertension, high levels of cholesterol as well as certain medical conditions such as acromegaly, Cushing’s syndrome, thyrotoxicosis, pheochromocytoma, chronic pancreatitis, cancer and drugs.

Additional factors found to increase the risk of type 2 diabetes include aging, high-fat diets and a less active lifestyle. In addition it is now believed that there is a strong genetic link to Type 2 diabetes, and having a family history of Type 2 diabetes increases the risk of developing this condition exponentially.
