Having asthma does not necessarily mean having a complicated pregnancy. With proper management of asthma and appropriate medical care during the pregnancy, most women who have asthma can experience healthy pregnancies.
Asthma is 1 of the most common diseases that can complicate a pregnancy. In some cases, a diagnosis of asthma is not made until a woman becomes pregnant. Asthma affects a woman during pregnancy in a variety of ways, including:
Over one-third of women experience no change in their symptoms of asthma.
Over one-third of pregnant women experience more severe symptoms of asthma.
Less than one-third of pregnant women experience improved symptoms of asthma.
Symptoms may become more severe as weight increases with pregnancy.
Treating asthma properly during pregnancy is important. Uncontrolled asthma can lead to decreased oxygen intake for the mother, which, in turn, affects the fetus.
Uncontrolled asthma can lead to any of the complications listed below.
Asthma, when not controlled, can put undue stress on the mother as well as on the fetus. Lack of oxygen will not only deprive the mother, but also the fetus. Other complications from uncontrolled asthma for the mother include:
Preeclampsia (also known as toxemia in pregnancy). A disorder of pregnancy characterized by increased blood pressure, water retention, and protein in the urine.
Gestational hypertension. This is high blood pressure during pregnancy
Hyperemesis gravidarum. A pregnancy disorder characterized by long-term vomiting, weight loss, and fluid and electrolyte imbalances.
Vaginal hemorrhage. This is bleeding through the vagina
Lack of oxygen to the fetus from the mother can lead to many health problems in the fetus, including:
Intrauterine growth retardation. Poor fetal growth in the womb, causing the fetus to be smaller than normal for its gestational age.
Neonatal hypoxia. Inadequate oxygen for the fetus
Most asthma medicines are not harmful to the fetus or to the nursing baby. In fact, uncontrolled asthma may actually put the mother and fetus at far greater risk than the medicine used to control asthma. Always talk with your healthcare provider for a diagnosis and to develop a specific asthma treatment plan tailored to your symptoms.
The American Congress of Obstetricians and Gynecologists recommends a pregnant woman take the following steps to reduce the risk of having an asthma attack during her pregnancy:
Avoid asthma triggers, including tobacco smoke and other irritants.
Continue asthma medicines throughout the pregnancy, labor, and delivery, as advised by your healthcare provider.
Exercise with moderation (use medicine properly if you have exercise-induced asthma and consult your healthcare provider before beginning an exercise program).
Make sure to get a flu shot, if you will be in your second or third trimester of pregnancy during the influenza (fall-winter) season.
Even with a proper asthma management plan in place, a pregnant woman should be aware of certain warning signs that may indicate an asthma attack, such as:
Current medicine does not provide rapid improvement of symptoms.
Improvement from medicines does not continue as long as it had before.
Breathing becomes more difficult.
Fetal kick count decreases. This may indicate fetal distress.
Always talk with your healthcare provider about what asthma attack warning signs to look for and when to seek emergency medical treatment.
