A doctor will likely diagnose gestational diabetes if you have at least two of the following values :. Many people who experience gestational diabetes will develop type 2 diabetes outside of pregnancy. There are two other types of diabetes:. The ADA also encourages doctors to screen for type 2 diabetes at the beginning of pregnancy.

If you have risk factors for type 2 diabetes, a doctor will likely test you for the condition at your first prenatal visit. These risks factors include :.

According to the CDC , being an African American, Hispanic or Latino, American Indian, or Alaska Native person may also increase your risk of developing type 2 diabetes.

The CDC also notes that some Pacific Islanders and Asian American people may also have a higher risk. Gestational diabetes is divided into two classes :.

If you receive a diagnosis of gestational diabetes, your treatment plan will depend on your blood sugar levels throughout the day. In most cases, a doctor will advise you to test your blood sugar before and after meals. If a doctor encourages you to monitor your blood sugar levels , they may provide you with a glucose-monitoring device.

A doctor may also prescribe insulin injections for you until you give birth. Ask them about properly timing your insulin injections in relation to your meals and exercise to avoid low blood sugar.

A doctor can also tell you what to do if your blood sugar levels fall too low or are consistently higher than they should be. A balanced diet can help manage gestational diabetes.

In particular, people with gestational diabetes can pay special attention to their carbohydrate, protein, and fat intake. The CDC recommends working with a dietitian to develop a nutritious eating plan or following meal plans, such as the plate method.

You may also need to avoid certain foods if you have gestational diabetes. According to a review of literature , the ADA, along with the American Academy of Nutrition and Dietetics, recommends all pregnant people eat a minimum of g of carbohydrates and 28 g of fiber per day.

For people with gestational diabetes, the American College of Obstetrics and Gynecologists ACOG recommends eating complex carbohydrates over simple ones. Complex carbs are digested more slowly, are less likely to produce high blood sugar, and may help reduce insulin resistance.

The recommended dietary allowance RDA of protein during pregnancy varies by trimester and may vary based on your individual needs. During the first trimester of pregnancy, the RDA is about 46 g of protein per day. However, ACOG lists certain types of fish that should be avoided due to their high mercury content, including tuna and swordfish.

Healthy sources of fat can provide nutrients, such as vitamins and minerals. Health-promoting fats to incorporate into your diet include:. If gestational diabetes is not managed well or left untreated, blood sugar levels may remain higher than they should be throughout your pregnancy.

This can lead to complications that affect the health of you and your baby before, during, and after birth. To avoid these complications, you can take steps to manage your gestational diabetes. Your blood sugar should return to typical levels after you give birth.

But developing gestational diabetes raises your risk of type 2 diabetes later in life. A doctor will test you for diabetes 6 to 12 weeks after your baby is born, and again every 1 to 3 years. Taking steps to prevent type 2 diabetes can also help prevent associated complications.

However, changing your lifestyle can help reduce your risk of developing it. Even light activity, such as walking, may be beneficial. A doctor can help you create a plan to reach and maintain a moderate weight. Even losing a small amount of weight can help reduce the risk of gestational diabetes.

Gestational diabetes occurs when the body cannot produce the insulin needed during pregnancy, resulting in high blood sugar. If you have gestational diabetes, a doctor may recommend changes to your diet along with blood sugar monitoring to help manage the condition. In some cases, you may need insulin injections.

In many cases, if you have gestational diabetes during pregnancy, your blood sugar should return to your typical levels after you give birth. However, you may have a higher risk of developing type 2 diabetes later in life. Besides causing discomfort to the woman during the last few months of pregnancy, an extra-large baby can lead to problems during delivery for both the mother and the baby.

The mother might need a C-Section to deliver the baby. The baby can be born with nerve damage due to pressure on the shoulder during delivery.

A woman who has diabetes that is not well controlled has a higher chance of needing a C-section to deliver the baby. When the baby is delivered by a C-section, it takes longer for the woman to recover from childbirth. It is a serious problem that needs to be watched closely and managed by her doctor.

High blood pressure can cause harm to both the woman and her unborn baby. It might lead to the baby being born early and also could cause seizures or a stroke a blood clot or a bleed in the brain that can lead to brain damage in the woman during labor and delivery.

Women with diabetes have high blood pressure more often than women without diabetes. Listen to this Podcast: Gestational Diabetes. People with diabetes who take insulin or other diabetes medications can develop blood sugar that is too low.

Low blood sugar can be very serious, and even fatal, if not treated quickly. Seriously low blood sugar can be avoided if women watch their blood sugar closely and treat low blood sugar early. If you've had gestational diabetes, you have a greater chance of having it in a future pregnancy.

You're also more likely to develop type 2 diabetes. Follow-up care is a key part of your treatment and safety.

Be sure to make and go to all appointments, and call your doctor or nurse advice line in most provinces and territories if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

Call anytime you think you may need emergency care. For example, call if:. Call your doctor or nurse advice line now or seek immediate medical care if:.

These sweeteners have not been linked to an increased risk of congenital anomalies birth defects.

Other protein foods like cheese, eggs, nuts, seeds, and peanut butter are also good for you and your baby. Avoid fruit juice or limit percent fruit juice to one-half cup 4 ounces per serving. Many dieticians recommend avoiding fruits for breakfast because of concerns about higher blood sugar levels in the early morning.

Choose low-fat yogurt that is plain, "light," or Greek style. Include plenty of salads, greens spinach, collards, kale , broccoli, carrots, green beans, tomatoes, onions, mushrooms, and other vegetables you enjoy.

Half of the plate at your meals can be non-starchy vegetables. Blood sugar monitoring — You will learn how to check your blood sugar level and record the results figure 1.

Instructions for choosing a blood sugar meter, checking blood sugar levels at home, and ways to record the results are discussed separately. See "Patient education: Glucose monitoring in diabetes Beyond the Basics ". This information can help to determine whether your blood sugar levels are on target.

If your levels stay higher than they should be, your doctor will probably recommend that you start using insulin. See 'Insulin' below. Exercise — Although exercise is not a necessary part of gestational diabetes treatment, it might help to control blood sugar levels. If you were exercising before, you should continue after being diagnosed with gestational diabetes.

If you did not previously exercise, ask your doctor or nurse if exercise is recommended. Most individuals who do not have medical or pregnancy-related complications are able to exercise, at least moderately, throughout their pregnancy. Walking is a great form of exercise for those starting an exercise regimen.

Insulin — Approximately 15 percent of patients with gestational diabetes will require insulin. Insulin is a medicine that helps to reduce blood sugar levels and can reduce the risk of gestational diabetes-related complications.

Insulin is the most common medicine for treating gestational diabetes. You must give insulin by injection because it does not work when it is taken by mouth. Most pregnant people start by giving one to two shots of insulin per day.

If your blood sugar levels are high after eating, you may need to give yourself a shot three or four times per day. Instructions for drawing up and giving insulin shots are available separately.

See "Patient education: Type 2 diabetes: Insulin treatment Beyond the Basics ". If you take insulin, you should check your blood sugar level at least four times per day. You also need to write down your results or store them in the meter and how much insulin you took and review these records at each prenatal visit or more frequently based on your doctor's recommendation figure 1.

Keeping accurate records helps to adjust insulin doses and can decrease the risk of complications. The bedtime snack is especially important to help keep your fasting first blood sugar of the day before eating in range.

Oral diabetes medicines, such as those taken by people with type 2 diabetes, are sometimes used during pregnancy in the United States. We prefer insulin therapy for pregnant patients with diabetes who cannot control blood glucose levels adequately by their diet nutritional therapy.

Insulin is effective and safe and does not cross the placenta to the fetus. Most oral diabetes medicines pass from the pregnant individual to their baby through the placenta; while they have not been shown to harm the fetus or newborn, it is not known if there are longer term effects on children.

There are studies underway to help answer this question. However, oral anti-hyperglycemic agents are a reasonable alternative for individuals who will not take, or are unable to comply with, insulin therapy, as long as they understand the lack of information on long-term risks or benefits.

Prenatal visits — Most pregnant individuals who develop gestational diabetes have more frequent prenatal visits eg, once every week or two , especially if insulin is used.

The purpose of these visits is to monitor your and your baby's health, discuss your diet, review your blood sugars, and adjust your dose of insulin if you are taking it to keep your blood sugar levels near normal.

It is common to change the dose of insulin as the pregnancy progresses. You may also be asked to have one or two ultrasound examinations to check on the growth and size of the baby. See "Gestational diabetes mellitus: Obstetric issues and management".

Nonstress testing — You may need tests to monitor the health of the baby during the later stages of pregnancy, especially if your blood sugars have been high, you are using insulin, or if you have any pregnancy-related complications eg, high blood pressure.

The most commonly used test is the nonstress test. This test is discussed in a separate topic review. See "Patient education: Postterm pregnancy Beyond the Basics ".

If your blood sugar levels are close to normal during pregnancy and you have no other complications, the ideal time to give birth is between 39 and 40 weeks of pregnancy, no later than your due date. If you do not give birth by your due date, you may be offered induction of labor or additional testing to monitor your and your baby's health.

In most individuals with gestational diabetes and a normal-size baby, there are no advantages to a cesarean over a vaginal birth, although cesarean may be needed in any pregnancy, especially with a first baby.

Those with a very large baby may be offered cesarean birth before labor starts. The risks and benefits of cesarean birth are discussed separately.

See "Patient education: C-section cesarean delivery Beyond the Basics ". Your blood sugar levels will be monitored during labor. Most individuals have normal blood sugar levels during labor and do not need any insulin. Insulin is given if your blood sugar level becomes high. High blood sugar levels during labor can cause problems in the baby, both before and after delivery.

See "Pregestational preexisting and gestational diabetes: Intrapartum and postpartum glucose management". AFTER-DELIVERY CARE. After giving birth, most individuals with gestational diabetes have normal blood sugar levels and do not require further treatment with insulin.

You can return to your prepregnancy diet, and you are encouraged to breastfeed. See "Patient education: Deciding to breastfeed Beyond the Basics ". However, your doctor may check your blood sugar level the day after delivery to be sure that it is normal or near normal. Pregnancy itself does not increase the risk of developing type 2 diabetes.

However, having gestational diabetes does increase your risk of developing type 2 diabetes later in life. After you deliver, you should have testing for type 2 diabetes.

Typically, this is done between 4 and 12 weeks postpartum, ideally prior to your postpartum check-up. But it may be done in the hospital before you are discharged. Testing usually includes a two-hour glucose tolerance test GTT so that you are tested for both pre-diabetes and diabetes.

Risk of recurrent gestational diabetes — One-third to two-thirds of individuals who have gestational diabetes in one pregnancy will have it again in a later pregnancy. If you are overweight or obese, weight reduction through diet and exercise can reduce this risk.

Risk of developing type 2 diabetes — Individuals with gestational diabetes have an increased risk of developing type 2 diabetes later in life, especially if they have other risk factors eg, family history of type 2 diabetes.

The risk of developing type 2 diabetes is greatly affected by body weight. Individuals with obesity have a 50 to 75 percent risk of developing type 2 diabetes, while this risk is less-than percent in those who are a normal weight. If you are overweight or obese, you can reduce your risk of type 2 diabetes by losing weight and exercising regularly.

The American Diabetes Association ADA recommends that all persons with a history of gestational diabetes have testing for type 2 diabetes every one to three years after their initial post-pregnancy test for diabetes. If you have elevations in your blood sugars in the pre-diabetes range at the time of your postpartum screening, the ADA recommends testing yearly testing.

It is also recommended that you work with your primary care provider to eat a healthy diet, lose any excess weight, and exercise regularly to help decrease your risk of developing type 2 diabetes.

Cardiovascular disease — Individuals who have had gestational diabetes in the past are at increased risk of developing cardiovascular disease, including heart attack and stroke. While this is mostly tied to the risk of type 2 diabetes see above , even those who do not develop type 2 diabetes appear to have a small increase in their risk of heart disease later in life.

Continuing to make healthy lifestyle choices such as eating a balanced diet, exercising regularly, and avoiding smoking can help minimize this risk. See "Patient education: Diet and health The Basics ". Birth control — Individuals with a history of gestational diabetes can use any type of birth control after pregnancy.

A review of all of the birth control options is available separately. See "Patient education: Birth control; which method is right for me? Beyond the Basics ". Your health care provider is the best source of information for questions and concerns related to your medical problem.
