Risk factors[]

Following are the major risk factors which may aggravate conditions of prediabetes:

  • Over weight or [[obesity]]: This is a major risk factor for prediabetes. Fatty tissue cells and muscles become more resistant to insulin creating condition of prediabetes.
  • Inactive lifestyle: Having an inactive lifestyle makes one prone to the condition of prediabetes.
  • Family history of type 2 diabetes: People with a family history of diabetes are more prone to develop prediabetes compared to people without any family history of diabetes. In this context, family means one or both parents and sibling.
  • Age and race: Higher the age, higher is the risk of prediabetes, and particularly after the age of 45 the risk is very high. With increasing age, most of the people tend to become physically inactive, gain weight while losing the muscle - factors which contribute to the condition of prediabetes. However, the condition is increasing even in children, teenagers and young adults. Similarly, certain ethnic groups are more prone to develop prediabetes. For example, around 50% of the Pima Indians of Arizona have diabetes.
  • Gestational diabetes: This is a contributing factor for prediabetes. For example. a woman who developed gestational diabetes while pregnant or gave birth to a baby weighing 9 pounds or more, has a higher risk of developing type 2 diabetes.
  • Depression: Risk of type 3 diabetes increases with depression, probably because people with depression tend to remain inactive and become overweight.
