What is Type 2 diabetes? And who is at risk?
The most common form of diabetes is Type 2 diabetes. About 90 to 95 percent of people with diabetes have Type 2. This form of diabetes is associated with older age, but today, many children and adolescents are being diagnosed with the condition. Obesity, family history of diabetes, previous history of gestational diabetes (diabetes that occurs during pregnancy), physical inactivity, and ethnicity are other risk factors for developing Type 2 diabetes. About 80 percent of people with type 2 diabetes are overweight.
When Type 2 diabetes is diagnosed, the pancreas is usually producing enough insulin, but for unknown reasons, the body cannot use the insulin effectively. This condition is called insulin resistance. After several years, insulin production decreases. The result is the same as for Type 1 diabetes—glucose builds up in the blood and the body cannot make efficient use of its main source of fuel.
What are the symptoms of Type 2 diabetes?
The symptoms of Type 2 diabetes develop gradually. Their onset is not as sudden as in Type 1 diabetes. Symptoms may include:
- Fatigue
- Nausea
- Frequent urination
- Unusual thirst
- Weight loss
- Blurred vision
- Frequent infections
- Slow healing of wounds or sores
- Some people have no symptoms at all
How Is Type 2 Diabetes Treated?
Simply put, a healthy lifestyle may help prevent or control Type 2 diabetes. In fact, up to 90 percent of cases may be preventable through diet and exercise, according to a study published in the September 13, 2001 issue of the New England Journal of Medicine.
Getting regular exercise like walking, cycling, or swimming, and eating a low-fat diet with lots of fruits, vegetables and fiber can help many people control their condition without insulin shots or pills. Diet and exercise are especially important for people who are overweight or obese. According to a report in the June 2001 issue of Nursing Clinics of North America, losing just 12 to 30 pounds can greatly reduce a person's need to take medication for diabetes.
A healthy eating plan for a person with diabetes is the same as for anyone else. It should be low in fat (less than 30 percent of calories from fat), and include lots of fruits, vegetables and fiber. People with diabetes have to be extra cautious however. While no food is off-limits, eating too many sugary or high-carbohydrate foods like candy or white potatoes, can send blood sugar soaring. Anyone with diabetes should get help from a registered dietitian (RD) or an experienced certified diabetes educator (CDE) to plan balanced meals.
Unfortunately for some, diet and exercise alone may not be enough to get blood sugar to a normal level. If lifestyle changes don't lower a person’s blood sugar within a month or two, his/her doctor may prescribe a pill that can help lower it.
Like those with Type 1 diabetes, persons with Type 2 should schedule regular checkups with their doctor, especially routine A1C tests.
Diabetes is a serious condition. But the good news is worth repeating: About 90 percent of cases of Type 2 diabetes may be prevented with proper lifestyle changes including a healthy eating plan and regular exercise.
