Diabetes

What is diabetes?


Diabetes is a disease in which blood glucose levels are above normal. Most of the food we eat is turned into glucose, or sugar, for our bodies to use for energy. The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies. When you have diabetes, your body either doesn't make enough insulin or can't use its own insulin as well as it should. This causes sugar to build up in your blood.

Diabetes can cause serious health complications including heart disease, blindness, kidney failure, and lower-extremity amputations. Diabetes is the sixth leading cause of death in the United States.



What are the symptoms of diabetes?

People who think they might have diabetes must visit a physician for diagnosis. They might have SOME or NONE of the following symptoms:

• Frequent urination

• Excessive thirst

• Unexplained weight loss

• Extreme hunger

• Sudden vision changes

• Tingling or numbness in hands or feet

• Feeling very tired much of the time

• Very dry skin

• Sores that are slow to heal

• More infections than usual.

Nausea, vomiting, or stomach pains may accompany some of these symptoms in the abrupt onset of insulin-dependent diabetes, now called type 1 diabetes.



What are the risk factors for diabetes?

Risk factors for type 2 diabetes include older age, obesity, family history of diabetes, prior history of gestational diabetes, impaired glucose tolerance, physical inactivity, and race/ethnicity. African Americans, Hispanic/Latino Americans, American Indians, and some Asian Americans and Pacific Islanders are at particularly high risk for type 2 diabetes.

Risk factors are less well defined for type 1 diabetes than for type 2 diabetes, but autoimmune, genetic, and environmental factors are involved in developing this type of diabetes.

Gestational diabetes occurs more frequently in African Americans, Hispanic/Latino Americans, American Indians, and people with a family history of diabetes than in other groups. Obesity is also associated with higher risk. Women who have had gestational diabetes are at increased risk for later developing type 2 diabetes. In some studies, nearly 40% of women with a history of gestational diabetes developed diabetes in the future.

Other specific types of diabetes, which may account for 1% to 2% of all diagnosed cases, result from specific genetic syndromes, surgery, drugs, malnutrition, infections, and other illnesses.



Can diabetes be prevented?

A number of studies have shown that regular physical activity can significantly reduce the risk of developing type 2 diabetes. Type 2 diabetes is associated with obesity.

Researchers are making progress in identifying the exact genetics and "triggers" that predispose some individuals to develop type 1 diabetes, but prevention remains elusive.



Prevent Diabetes

Research studies have found that moderate weight loss and exercise can prevent or delay type 2 diabetes among adults at high-risk of diabetes. Find out more about the risk factors for type 2 diabetes, what it means to have prediabetes, and what you can do to prevent or delay diabetes. See also EAT RIGHT and BE ACTIVE.

What are the most important things to do to prevent diabetes?

The Diabetes Prevention Program (DPP) , a major federally funded study of 3,234 people at high risk for diabetes, showed that people can delay and possibly prevent the disease by losing a small amount of weight (5 to 7 percent of total body weight) through 30 minutes of physical activity 5 days a week and healthier eating.



What are the risk factors which increase the likelihood of developing diabetes?

Being overweight or obese

A parent, brother, or sister with diabetes

African American, American Indian, Asian American, Pacific Islander, or Hispanic American/Latino heritage

Prior history of gestational diabetes or birth of at least one baby weighing more than 9 pounds

High blood pressure measuring 140/90 or higher

Abnormal cholesterol with HDL ("good") cholesterol is 35 or lower, or triglyceride level is 250 or higher

Physical inactivity—exercising fewer than three times a week



How does body weight affect the likelihood of developing diabetes?

Being overweight or obese is a leading risk factor for type 2 diabetes. Being overweight can keep your body from making and using insulin properly, and can also cause high blood pressure. The Diabetes Prevention Program (DPP) , a major federally funded study of 3,234 people at high risk for diabetes, showed that moderate diet and exercise of about 30 minutes or more, 5 or more days per week, or of 150 or more minutes per week, resulting in a 5% to 7% weight loss can delay and possibly prevent type 2 diabetes.



What is pre-diabetes?

People with blood glucose levels that are higher than normal but not yet in the diabetic range have "pre-diabetes." Doctors sometimes call this condition impaired fasting glucose (IFG) or impaired glucose tolerance (IGT), depending on the test used to diagnose it. Insulin resistance and pre-diabetes usually have no symptoms. You may have one or both conditions for several years without noticing anything.

If you have pre-diabetes, you have a higher risk of developing type 2 diabetes. Studies have shown that most people with pre-diabetes go on to develop type 2 diabetes within 10 years, unless they lose weight through modest changes in diet and physical activity. People with pre-diabetes also have a higher risk of heart disease.

Progression to diabetes among those with prediabetes is not inevitable. Studies suggest that weight loss and increased physical activity among people with prediabetes prevent or delay diabetes and may return blood glucose levels to normal.
