MESA, AZ - Doctors at Cardon Children's Medical Center blame heat for an increased number of preterm deliveries.
Over the summer, they have seen a 33-percent increase in patients who have gone into labor earlier than expected.
Dehydration may be the cause, said Dr. Jamal Mourad, an OB-GYN at Banner Desert
If you're pregnant, doctors urge you stay hydrated
Drink lots of fluids, Mourad said.
Mourad said dehydration is a common problem during the summer months in Phoenix because blood volume changes quite dramatically in pregnant women.
When you add heat or heat exhaustion, you can deplete your fluid which can lead to contractions of the uterus, which if persistent, can lead to preterm labor and delivery, Mourad added.
If you're going to exercise, he said be proactive and drink enough water before the exercise regiment. Eat lots of fruits and veggies because provide sustenance that helps with dehydration.
The best approach is to stay out of the heat, Mourad said.
