When you have diabetes, your body either doesn’t make enough insulin or can’t use its own insulin as well as it should, or both. This causes sugars to build up too high in your blood.
What types of diabetes are there?
There are two main forms of diabetes: type 1 and type 2.
Type 2 is the most common. About 90 percent to 95 percent of Americans diagnosed with diabetes have type 2 diabetes. It most often develops in middle-aged and older adults. It’s often linked with being overweight, obese and physically inactive.
Type 2 diabetes develops when the body doesn’t make enough insulin and doesn’t efficiently use the insulin it makes (insulin resistance).
Type 1 diabetes usually starts early in life. It results from the body’s failure to produce insulin. People with it must take insulin each day to control their levels of blood glucose (sugar).
Am I at risk?
The number of people with diabetes is increasing. This is because more people are overweight or obese, don’t get enough physical activity and are getting older. However, many younger people are developing diabetes at an alarming rate. This is probably because being overweight, obese and not getting enough physical activity are increasing problems for this group, too.
People in several ethnic groups seem to be more likely to develop type 2 diabetes. These include:
- African Americans
- Native Americans
- Asians (especially South Asians)
Diabetes is a major risk factor for stroke and heart disease. That means it can be as serious as smoking, high blood cholesterol, high blood pressure, physical inactivity or obesity.
If you have diabetes, it’s very important to have regular check-ups. Work closely with your healthcare provider to manage your diabetes and reduce any other risk factors:
- Manage your weight, blood pressure and blood cholesterol with a heart healthy eating plan that is low in saturated fat, trans fat, cholesterol, salt (sodium) and added sugars.
- Be physically active. Aim for at least 150 minutes (2 hours and 30 minutes) of moderate-intensity, or 75 minutes (1 hour and 15 minutes) of vigorous-intensity, aerobic exercise each week.
- If you drink alcohol, don’t have more than one drink per day for women or two per day for men.
- Lower your blood pressure, if it’s too high. People with diabetes should keep blood pressure under 130/80 mm Hg.
- Don’t smoke, and avoid second-hand smoke.
- If you take medicine, take it exactly as directed. If you have questions about the dosage or side effects, ask your doctor or pharmacist.
- Talk to your doctor, nurse or other healthcare professionals. If you have heart disease or have had a stroke, members of your family also may be at higher risk. It’s very important for them to make changes now to lower their risk.
