Diabetes is a disease in which blood sugar (glucose) levels in your body are too high. Diabetes can cause serious health problems, including heart attack or stroke, blindness, problems during pregnancy, and kidney failure. More than 13 million women have diabetes, or about one in 10 women ages 20 and older.1
Diabetes is a disease caused by high levels of blood sugar (glucose) in your body. This can happen when your body does not make insulin or does not use insulin correctly.
Insulin is a hormone made in the pancreas, an organ near your stomach. Insulin helps the glucose from food get into your body's cells for energy. If your body does not make enough insulin, or your body does not use the insulin correctly, the glucose stays and builds up in your blood.
Over time, this extra glucose can lead to prediabetes or diabetes. Diabetes puts you at risk for other serious and life-threatening health problems, such as heart disease, stroke, blindness, and kidney damage.
Type 1 diabetes. Type 1 diabetes is an autoimmune disease, meaning the body's immune (defense) system attacks and destroys the cells in the pancreas that make insulin. If you have type 1 diabetes, your body does not make insulin, so you must take insulin every day.
Type 2 diabetes. This is the most common type of diabetes. You can get type 2 diabetes at any age, even during childhood. With type 2 diabetes, your body does not make enough insulin or is not able to use its own insulin correctly. When this happens, blood glucose levels rise.
Gestational(jess-TAY-shun-ul) diabetes. Gestational diabetes is a type of diabetes that happens only during pregnancy. Gestational diabetes can cause health problems for the baby and the mother if not controlled. Although gestational diabetes goes away after your baby is born, having diabetes during pregnancy raises your risk for type 2 diabetes later on.2 Learn more about gestational diabetes at the National Diabetes Information Clearinghouse.
Older age: 45 or older. After menopause, women are at higher risk for weight gain, especially more weight around the waist, which raises the risk for type 2 diabetes.
Family health history: Having a mother, father, brother, or sister with diabetes
Race/ethnicity: Family background of African-American, American Indian/Alaska Native, Hispanic, Asian-American, and Native Hawaiian/Pacific Islander
Having a baby that weighed 9 pounds or more at birth
Having diabetes during pregnancy (gestational diabetes)
High blood pressure: Taking medicine for high blood pressure or having a blood pressure of 140/90 mmHg or higher. (Both numbers are important. If one or both numbers are usually high, you have high blood pressure.)
High cholesterol: HDL cholesterol of 35 mg/dL or lower and triglycerides of 250 mg/dL or higher
Lack of physical activity: Women who are active less than three times a week
Type 1 diabetes usually develops in childhood, but it can happen at any age. It is more common in whites than in other racial or ethnic groups. About 5% of adults with diabetes have type 1 diabetes.1 Genes you inherit from your parents play an important role in the development of type 1 diabetes. However, where you live may also affect your risk. Type 1 diabetes develops more often in winter and in people who live in colder climates.
Type 2 diabetes is more common in adults, especially in people who are overweight and have a family history of diabetes. About 95% of adults with diabetes have type 2 diabetes.1 Type 2 diabetes is becoming more common in children and teens as more of them become overweight and obese.5
Yes. Certain racial and ethnic groups have a higher risk for type 2 diabetes. These groups include:
African-Americans. African-American women are twice as likely to develop diabetes as white women.6 African-Americans are also more likely to have health problems caused by diabetes and excess weight.
Hispanics. Hispanic women are twice as likely to develop diabetes as white women.6 Diabetes affects more than one in 10 Hispanics. Among Hispanic women, diabetes affects Mexican-Americans and Puerto Ricans most often.1
American Indian/Alaskan Native. Diabetes affects nearly 16% of American Indian/Alaskan Native adults.1
Native Hawaiian/Pacific Islander. Native Hawaiians/Pacific Islanders are about twice as likely to develop diabetes as whites.7
Asian-Americans. Diabetes is the fifth-leading cause of death for Asian-Americans. Asian-American women are also more likely to develop gestational diabetes than white women and usually develop gestational diabetes at a lower body weight.8
Yes. The longer you have type 2 diabetes, the higher your risk for developing serious medical problems from diabetes. Also, if you smoke and have diabetes, you are even more likely to develop serious medical problems from diabetes, compared with people who have diabetes and do not smoke. 11
The extra glucose in the blood that leads to diabetes can damage your nerves and blood vessels. Nerve damage from diabetes can lead to pain or a permanent loss of feeling in your hands, feet, and other parts of your body.12
Blood vessel damage from diabetes can also lead to:
Leg or foot amputation
Women with diabetes are also at higher risk for:
Problems getting pregnant
Problems during pregnancy, including possible health problems for you and your baby
Researchers do not know the exact causes of type 1 and type 2 diabetes. Researchers do know that inheriting certain genes from your family can raise your risk for developing diabetes. Obesity is also a major risk factor for type 2 diabetes. Smoking can also cause type 2 diabetes. And the more you smoke the higher your risk for type 2 diabetes and other serious health problems if you already have diabetes.13
Weight loss can help control type 2 diabetes so that you are healthier. Quitting smoking can also help you control your blood sugar levels. Being a healthy weight and not smoking can help all women be healthier.
But, obesity and smoking do not always cause diabetes. Some women who are overweight or obese or smoke never develop diabetes. Also, women who are a normal weight or only slightly overweight can develop diabetes if they have other risk factors, such as a family history of diabetes.
Maybe. You should be tested for diabetes if you are between 40 and 70 years old and are overweight or obese. Your doctor may recommend testing earlier than age 40 if you also have other risk factors for diabetes. Also, talk to your doctor about diabetes testing if you have signs or symptoms of diabetes. Your doctor will use a blood test to see if you have diabetes.
If the testing shows that your blood sugar levels are high, you can begin making healthy changes to your eating habits and getting more physical activity to help prevent diabetes.
Prediabetes means your blood sugar (glucose) level is higher than normal, but it is lower than the diabetes range. It also means you are at higher risk of getting type 2 diabetes and heart disease.
As many as 27 million American women have prediabetes.14 If you have prediabetes, you can make healthy changes, such as doing some type of physical activity on most days, to lower your risk of getting diabetes and return to normal blood sugar levels. Losing 7% of your body weight (or 14 pounds if you weigh 200 pounds) can lower your risk for type 2 diabetes by more than half. If you have prediabetes, get your blood glucose checked every year by a doctor or nurse.15
Diabetes treatment includes managing your blood sugar levels to control your symptoms. You can help control your blood sugar levels by eating healthy and getting regular physical activity.
With type 1 diabetes, you also will need to take insulin through shots or an insulin pump. Insulin cannot be taken as a pill.
Type 2 diabetes treatment also may include taking medicine to control your blood sugar. Over time, people with type 2 diabetes make less and less of their own insulin. This may mean that you will need to increase your medicines or start taking insulin shots to keep your diabetes in control.
Yes. Many studies, including the large Diabetes Prevention Program study, have proven that you can prevent diabetes by losing weight. Weight loss through healthy eating and more physical activity improves the way your body uses insulin and glucose.
Weight loss: Obesity is a leading risk factor for diabetes. Calculate your BMI to see whether you’re at a healthy weight. If you’re overweight or obese, start making small changes to your eating habits and get more physical activity. Even a small amount of weight loss (7%, or about 14 pounds for a 200-pound woman) can delay or even prevent type 2 diabetes.
Eating healthy: Choose vegetables, whole grains (such as whole wheat or rye bread, whole grain cereal, or brown rice), beans, and fruit. Read food labels to help you choose foods low in saturated fat, trans fat, and sodium. Limit processed foods and sugary foods and drinks.
Getting active. Aim for 30 minutes of physical activity most days of the week and limit the amount of time you spend sitting.
Yes. If you have type 1 or type 2 diabetes, you can have a healthy pregnancy. If you have diabetes and you want to have a baby, you need to plan ahead, before you get pregnant.
Talk to your doctor before you get pregnant. He or she can talk to you about steps you can take to keep your baby healthy. This may include a diabetes education program to help you better understand your diabetes and how to control it during pregnancy.
