What is diabetes pre-diabetes and types of diabetes?

Q: What is diabetes?

A: Diabetes means that your blood glucose (sugar) is too high. Your blood always has some glucose in it because the body uses glucose for energy; it’s the fuel that keeps you going. But too much glucose in the blood is not good for your health.

Your body changes most of the food you eat into glucose. Your blood takes the glucose to the cells throughout your body. The glucose needs insulin to get into the body’s cells. Insulin is a hormone made in the pancreas, an organ near the stomach. The pancreas releases insulin into the blood. Insulin helps the glucose from food get into body cells. If your body does not make enough insulin or the insulin does not work right, the glucose can’t get into the cells, so it stays in the blood. This makes your blood glucose level high, causing you to have diabetes.

If not controlled, diabetes can lead to blindness, heart disease, stroke, kidney failure, amputations (having a toe or foot removed, for example), and nerve damage. In women, diabetes can cause problems during pregnancy and make it more likely that your baby will be born with birth defects.

 Q: What is pre-diabetes?

A: Pre-diabetes means your blood glucose is higher than normal but lower than the diabetes range. It also means you are at risk of getting type 2 diabetes and heart disease. There is good news though: You can reduce the risk of get­ting diabetes and even return to nor­mal blood glucose levels with modest weight loss and moderate physical activ­ity. If you are told you have pre-diabe­tes, have your blood glucose checked again in 1 to 2 years.

Q: What are the different types of diabetes?

A: The three main types of diabetes are:

• Type 1 diabetes is commonly diag­nosed in children and young adults, but it’s a lifelong condition. If you have this type of diabetes, your body does not make insulin, so you must take insulin every day. Treatment for type 1 diabetes includes taking insu­lin shots or using an insulin pump, making healthy food choices, get­ting regular physical activity, taking aspirin daily (for many people), and controlling blood pressure and cho­lesterol levels.

• Type 2 diabetes is the most com­mon type of diabetes — about 9 out of 10 people with diabetes have type 2 diabetes. You can get type 2 dia­betes at any age, even during child­hood. In type 2 diabetes, your body makes insulin, but the insulin can’t do its job, so glucose is not getting into the cells. Treatment includes taking medicine, making healthy food choices, getting regular physi­cal activity, taking aspirin daily (for many people), and controlling blood pressure and cholesterol levels. If you have type 2 diabetes, your body gen­erally produces less and less insulin over time. This means that you may need to increase your medications or start using insulin in order to keep your diabetes in good control.

• Gestational (jess-TAY-shun-ul) diabetes occurs during pregnancy. This type of diabetes occurs in about 1 in 20 pregnancies. During pregnancy your body makes hor­mones that keep insulin from doing its job. To make up for this, your body makes extra insulin. But in some women this extra insulin is not enough, so they get gestational diabetes. Gestational diabetes usu­ally goes away when the pregnancy is over. Women who have had ges­tational diabetes are very likely to develop type 2 diabetes later in life.
