Why You're So Thirsty During Pregnancy

Can't seem to quench your thirst? Here's maybe why.

Can’t seem to get enough to drink? Your body needs extra fluids during pregnancy, so it’s important to stay hydrated. If you’re feeling really thirsty, here’s what your body might be telling you.

Why You’re Feeling Thirsty During Pregnancy

The easiest and most common explanation is that you’re probably not drinking enough water. When you’re pregnant, your body needs even more fluids than usual to support baby’s blood circulation, amniotic fluid and your own higher blood volume, according to the National Institutes of Health. Another possible reason for your thirst? You may be feeling hotter and sweating more these days.

In extremely rare cases, excessive thirst could be a sign of gestational diabetes, but gestational diabetes usually doesn’t cause any symptoms at all—that’s why every pregnant woman gets tested for it, says Karen Deighan, MD, FACOG, department chairperson of Obstetrics and Gynecology at Gottlieb Memorial Hospital of Loyola University Health System. So there’s no reason to freak out about your excessive thirst. If you’re concerned, mention it at your next doctor’s visit.

What To Do For Excessive Thirst

Drink up! Have at least 10 glasses of water a day (that’s 2.3 liters)—more if it’s hot out or if you’ve been exercising or vomiting because of morning sickness.
