Diabetes and Pregnancy

What is diabetes?

If you have diabetes, your blood glucose, or blood sugar, levels are too high. Glucose comes from the foods you eat. A hormone called insulin helps the glucose get into your cells to give them energy. With type 1 diabetes, your body does not make insulin. With type 2 diabetes, your body does not make or use insulin well. Without enough insulin, the glucose stays in your blood.

What is gestational diabetes?

Some people already have diabetes before they get pregnant. But others may develop diabetes during pregnancy. This type of diabetes is called gestational diabetes. It usually develops around the 24th week of pregnancy. It happens when your body can't make the extra insulin it needs during pregnancy. Researchers think gestational diabetes is caused by the hormonal changes of pregnancy, along with genetic and lifestyle factors.

Who is more likely to develop gestational diabetes?

Anyone who is pregnant could develop gestational diabetes. But you are more likely to develop it if you:

How do I know if I have gestational diabetes?

Gestational diabetes often has no symptoms. If you do have symptoms, they may be mild, such as being thirstier than normal or having to urinate (pee) more often.

If you are pregnant, you will most likely be screened for gestational diabetes between 24 and 28 weeks of pregnancy. But if you have an increased chance of developing gestational diabetes, you may be tested during your first prenatal visit. Your health care provider will use one or more blood glucose tests to check for gestational diabetes. You may have the glucose challenge test, the oral glucose tolerance test (OGTT), or both.

For these two tests, you will drink a sugary liquid and wait for an hour before your blood sample is taken. If you have an oral glucose tolerance test, you will also get your blood drawn after 2 and 3 hours.

How can diabetes affect my pregnancy?

Having diabetes during pregnancy can affect your health. For example:

Having diabetes during pregnancy can also affect the health of your developing baby:

How can I manage diabetes during pregnancy?

There are steps you can take to manage your diabetes before, during, and after pregnancy.

If you already have diabetes, the best time to control your blood glucose is before you get pregnant. High blood glucose levels can be harmful to your developing baby during the first weeks of pregnancy, even before you know you are pregnant. See your provider to help you plan for pregnancy. You can talk about how to lower the risk of health problems for you and your developing baby. You can also discuss your diet, physical activity, and which diabetes medicines are safe during pregnancy.

During your pregnancy, you will work with your provider to manage your blood glucose levels. You may be able to manage them with a healthy diet and regular physical activity. If that's not enough, then you will need to take diabetes medicines. It's also important that you:

After pregnancy, there are steps you need to take to stay healthy:

Type 1 diabetes

Type 1 diabetes is a disorder characterized by abnormally high levels of blood glucose, also called blood sugar. In this form of diabetes, specialized cells in the pancreas called beta cells stop producing insulin. Insulin controls how much glucose (a type of sugar) is passed from the blood into cells for conversion to energy. Lack of insulin results in the inability to use glucose for energy or to control the amount of glucose in the blood.

Type 1 diabetes can occur at any age, from early childhood to late adulthood. The first signs and symptoms of the disorder are caused by high blood glucose and may include frequent urination (polyuria), excessive thirst (polydipsia), fatigue, blurred vision, tingling or loss of feeling in the hands and feet, and weight loss. These symptoms may recur during the course of the disorder if blood glucose is not well controlled by insulin replacement therapy. Improper control can also cause blood glucose levels to become too low (hypoglycemia). This may occur when the body's needs change, such as during exercise or if eating is delayed. Hypoglycemia can cause headache, dizziness, hunger, shaking, sweating, weakness, and agitation.

Uncontrolled type 1 diabetes can lead to a life-threatening complication called diabetic ketoacidosis. Without insulin, cells cannot take in glucose. A lack of glucose in cells prompts the liver to try to compensate by releasing more glucose into the blood, and blood glucose can become extremely high. The cells, unable to use the glucose in the blood for energy, respond by using fats instead. Breaking down fats to obtain energy produces waste products called ketones, which can build up to toxic levels in people with type 1 diabetes, resulting in diabetic ketoacidosis. Affected individuals may begin breathing rapidly; develop a fruity odor in the breath; and experience nausea, vomiting, facial flushing, stomach pain, and dryness of the mouth (xerostomia). In severe cases, diabetic ketoacidosis can lead to coma and death.

Over many years, the chronic high blood glucose associated with diabetes may cause damage to blood vessels and nerves, leading to complications affecting many organs and tissues. The retina, which is the light-sensitive tissue at the back of the eye, can be damaged (diabetic retinopathy), leading to vision loss and eventual blindness. Kidney damage (diabetic nephropathy) may also occur and can lead to kidney failure and end-stage renal disease (ESRD). Pain, tingling, and loss of normal sensation (diabetic neuropathy) often occur, especially in the feet. Impaired circulation and absence of the normal sensations that prompt reaction to injury can result in permanent damage to the feet; in severe cases, the damage can lead to amputation. People with type 1 diabetes are also at increased risk of heart attacks, strokes, and problems with urinary and sexual function.
