Pregnancy-related high blood pressure, diabetes linked to later heart disease
Most of the changes that come with pregnancy鈥攇rowing a belly 鈥渂ump,鈥� being tired, mood swings, cravings for particular foods, and the like鈥攁re normal, temporary, and harmless. Two other changes, pregnancy-related high blood pressure and diabetes, may have long-lasting implications for heart health.
The development of high blood pressure during pregnancy is known as preeclampsia; pregnancy-related diabetes is called gestational diabetes. They are different from 鈥渞egular鈥� high blood pressure and diabetes because both are 鈥渃ured鈥� by delivery. Yet a new study suggests that these complications boost a woman鈥檚 risk of cardiovascular disease during middle age.
Researchers looked at the pregnancies of more than 3,400 women enrolled in the in the early 1990s and followed their health for nearly 20 years. By age 50, the 10-year risk for heart disease was 31% higher for women who developed preeclampsia during their pregnancies than women who didn鈥檛. Those who developed gestational diabetes had a 26% higher 10-year risk.
Preeclampsia and gestational diabetes also affected the women鈥檚 babies. Women with preeclampsia were more likely to give birth to underweight babies and deliver prematurely. Women with gestational diabetes were more likely to deliver overweight babies.
Preventing problems before and after
The findings from the Avon Longitudinal Study suggest that pregnancy may be a kind of months-long 鈥渢est鈥� of the heart and other systems. Preeclampsia, gestational diabetes, and other pregnancy-related complications could be early signs of some underlying problem that eventually leads to heart disease.
Can these problems be avoided? Sometimes. Women who are not yet pregnant can help prevent them from occurring by aiming for a healthy weight, exercising, and adopting a healthy diet before getting pregnant. During pregnancy, being careful about weight gain, exercising, and eating well are even more important. That said, some women who are meticulous about all those things still develop preeclampsia or gestational diabetes.
If you developed preeclampsia or gestational diabetes during pregnancy, it鈥檚 a good idea to talk with your doctor about tracking your blood pressure and blood sugar more carefully as you get older. You might need to pay more close attention to them than someone who sailed through 聽pregnancy without either of these complications. And keeping your blood pressure, cholesterol, weight, and other cardiac risk factors under control may be especially important for you.
