Type 2 Diabetes Overview

Type 2 diabetes, often called non-insulin dependent diabetes, is the most common form of diabetes, affecting 90% - 95% of the 21 million people with diabetes. In this article, you'll learn the basics about type 2 diabetes, including symptoms and causes, as well as type 2 diabetes in children.

What Is Type 2 Diabetes?

Unlike people with type 1 diabetes, people with type 2 diabetes produce insulin; however, either their pancreas does not produce enough insulin or the body cannot use the insulin adequately. This is called insulin resistance. When there isn't enough insulin or the insulin is not used as it should be, glucose (sugar) can't get into the body's cells. When glucose builds up in the blood instead of going into cells, the body's cells are not able to function properly. Other problems associated with the buildup of glucose in the blood include:

  • Dehydration. The buildup of sugar in the blood can cause an increase in urination. When the kidneys lose the glucose through the urine, a large amount of water is also lost, causing dehydration.
  • Diabetic Coma (Hyperosmolar nonketotic diabetic coma) . When a person with type 2 diabetes becomes severely dehydrated and is not able to drink enough fluids to make up for the fluid losses, they may develop this life-threatening complication.
  • Damage to the body. Over time, the high glucose levels in the blood may damage the nerves and small blood vessels of the eyes, kidneys, and heart and predispose a person to atherosclerosis (hardening) of the large arteries that can cause heart attack and stroke.

 

Type 2 Diabetes in Children

More and more children are being diagnosed with type 2 diabetes. Find out about type 2 diabetes symptoms in children, the diagnosis, and the treatment in WebMD's article on type 2 diabetes in childhood. If your child is at risk for childhood diabetes, it’s important to learn specific self-care tips to help prevent diabetes.

Who Gets Type 2 Diabetes?

Anyone can get type 2 diabetes. However, those at highest risk for the disease are those who are obese or overweight, women who have had gestational diabetes, people with family members who have type 2 diabetes and people who have metabolic syndrome (a cluster of problems that include high cholesterol, high triglycerides, low good 'HDL' cholesterol and a high bad 'LDL' cholesterol, and high blood pressure). In addition, older people are more susceptible to developing the disease since aging makes the body less tolerant of sugars. 

In addition, people who smoke, have inactive lifestyles, or have certain dietary patterns have an increased risk of developing type 2 diabetes.
