What You Need to Know About Diabetes
High blood sugar. High blood glucose. Type 1. Type 2. Prediabetes. These terms can be confusing when talking about diabetes. But since 30.3 million Americans have this illness and another 84.1 million have prediabetes—a condition that can lead to diabetes—it’s important to get the lowdown on the disease and learn how to minimize the risk of developing it. What better time to do so than National Diabetes Awareness Month in November?
What Is Diabetes?
Diabetes is a chronic disease that occurs when abnormally high levels of sugar (also called glucose) are in the blood. When high levels of glucose remain in the bloodstream long-term, it can result in significant complications such as blindness, amputations, kidney failure, stroke and heart attack. Two main types of diabetes can develop: type 1 and type 2. Even though the names are similar, they are different diseases with unique causes.
With type 1 diabetes, your body’s immune system mistakes healthy cells for the enemy, and attacks and destroys insulin-producing beta cells in the pancreas, so the pancreas can’t make insulin. If you have type 2 diabetes, your pancreas may produce some insulin, but it may not make enough or you may be insulin-resistant, meaning your body doesn’t respond to insulin as well as it should. Prediabetes isn’t technically the same as diabetes, but it is a condition that, if untreated, often leads to type 2 diabetes within five years. While prediabetes may give few signs, type 1 and type 2 diabetes have noticeable symptoms, including:
- Frequent urination
- Feeling very thirsty
- Feeling hungry
- Feeling very tired
- Blurred vision
- Cuts or sores that don’t heal properly
- Those with type 1 diabetes also may be irritable, have mood changes and may unintentionally lose weight. Those with type 2 also may notice numbness or tingling in their hands and feet.
If you experience any of those symptoms or feel sick to your stomach, weak but thirsty, find yourself breathing deeper or faster than normal, or notice your breath has an unusually sweet odor like nail polish remover, talk with your doctor to see if you may have diabetes.
Risk Factors for Diabetes
Diabetes can occur in anyone, but some people have a higher risk than others. If you have close relatives with diabetes, are over 45, are overweight, or have belly fat, high cholesterol or high blood pressure, your odds of developing diabetes are higher. If you are a woman with polycystic ovarian syndrome (PCOS) or have ever had gestational diabetes or given birth to a baby weighing more than nine pounds, your risk increases as well. African Americans, Alaska Natives, Native Americans, Asian Americans, Hispanic/Latinos, Native Hawaiians and Pacific Islanders also have increased risk.
Preventing Diabetes
Although type 1 diabetes cannot be prevented, the risk of developing type 2 diabetes or prediabetes can be lowered through lifestyle changes.
Regular Checkups. Doctor will test your blood glucose, blood pressure and blood cholesterol levels.
Manage Your Weight. Excess body fat, particularly around the middle, can increase your resistance to insulin.
Exercise regularly. This will help you manage weight and reduce blood glucose levels. Eat a balanced, healthy diet. Add fruit, vegetables and high-fiber foods to your plate, while cutting back on salt, saturated and trans fats. Limit processed foods, which are often high in sodium and fat.
Limit Alcohol Intake. Too much alcohol can lead to weight gain and increase your blood pressure and triglyceride levels.
Quit Smoking. The Centers for Disease Control and Prevention (CDC) says that smoking causes type 2 diabetes, and that those who smoke are 30 percent to 40 percent more likely to develop diabetes than nonsmokers.
Diabetes is a serious disease that can be managed with your physician. Even better, type 2 diabetes can be prevented by recognizing the risks and symptoms, and making lifestyle changes that lead to a healthier outcome.
