Glucose intolerance during pregnancy
Causes, incidence, and risk factors
Pregnancy hormones can block insulin from doing its job. When this happens, glucose levels may increase in a pregnant woman’s blood.
You are at greater risk for gestational diabetes if you:
Are older than 25 when you are pregnant
Have a family history of diabetes
Gave birth to a baby that weighed more than 9 pounds or had a birth defect
high blood pressure
Have too much amniotic fluid
Have had an unexplained miscarriage or
Were overweight before your pregnancy
Usually there are no symptoms, or the symptoms are mild and not life threatening to the pregnant woman. The
Symptoms may include:
Blurred vision Fatigue
- Frequent infections, including those of the bladder, vagina, and skin
- Increased urination
- Nausea and vomiting
- Weight loss despite
Signs and tests
Gestational diabetes usually starts halfway through the pregnancy. All pregnant women should receive an
Once you are diagnosed with gestational diabetes, you can see how well you are doing by testing your glucose level at home. The most common way involves pricking your finger and putting a drop of your blood on a machine that will give you a glucose reading.
The goals of treatment are to keep blood sugar (glucose) levels within normal limits during the pregnancy, and to make sure that the growing baby is healthy.
WATCHING YOUR BABY
Your health care provider should closely check both you and your baby throughout the pregnancy. Fetal monitoring will check the size and health of the fetus.
- A machine that hears and displays your baby’s heartbeat (electronic fetal monitor) is placed on your abdomen.
- Your health care provider can compare the pattern of your baby’s heartbeat to movements and find out whether the baby is doing well.
DIET AND EXERCISE
The best way to improve your diet is by eating a variety of healthy foods. You should learn how to read food labels, and check them when making food decisions. Talk to your doctor or dietitian if you are a vegetarian or on some other special diet.
- Be moderate in fat and protein
- Provide your carbohydrates through foods that include fruits, vegetables, and complex carbohydrates (such as bread, cereal, pasta, and rice)
- Be low in foods that contain a lot of sugar, such as soft drinks, fruit juices, and pastries
If managing your diet does not control blood sugar (glucose) levels, you may be prescribed diabetes medicine by mouth or insulin therapy.
Most women with gestational diabetes are able to control their blood sugar and avoid harm to themselves or their baby.
Pregnant women with gestational diabetes tend to have larger babies at birth. This can increase the chance of problems at the time of delivery, including:
- Birth injury (trauma) because of the baby’s large size
- Delivery by
Your baby is more likely to have periods of low blood sugar (
Mothers with gestational diabetes have an increased risk for high blood pressure during pregnancy.
There is a slightly increased risk of the baby dying when the mother has untreated gestational diabetes. Controlling blood sugar levels reduces this risk.
High blood sugar (glucose) levels often go back to normal after delivery. However, women with gestational diabetes should be watched closely after giving birth and at regular doctor’s appointments to screen for signs of diabetes. Many women with gestational diabetes develop diabetes within 5 – 10 years after delivery.
Calling your health care provider
Call your health care provider if you are pregnant and you have symptoms of
Beginning prenatal care early and having regular prenatal visits helps improve your health and the health of your baby. Having prenatal screening at 24 – 28 weeks into the pregnancy will help detect gestational diabetes early.
