Are you pregnant and experiencing dry mouth? Here’s what might be causing it and some other information you should know


Would it surprise you to find out that up to 20% of people suffer from dry mouth, including pregnant women? Well, it’s true.

Everyone knows pregnancy is a time of excitement and total bliss, but it can also be a not-so-fun time of uncomfortable dry mouth symptoms for some expecting mothers. Standard symptoms include a constant sore throat, trouble speaking, tooth decay, and more. 

The truth is dry mouth is actually very common during pregnancy and typically occurs during the first trimester (weeks 1-12). Oh—and if you’re wondering why your mouth feels extra dry when you wake up, it’s because symptoms worsen at night.

So, what causes pregnancy-related dry mouth?

Let’s get right to it: dry mouth happens during pregnancy for several different reasons. Below are some of the most common causes:

Increased blood production

To accommodate the growing body, women in pregnancy produce more blood than women who are not pregnant. When there is more blood traveling through the body, more water is retained, causing dry mouth. Not to mention, the body excretes more of its fluids when there is an increase in blood production, making dry mouth symptoms worse.

Gestational diabetes

Gestational diabetes is a form of diabetes (high blood sugar) that only occurs in pregnant women. It’s a result of the body not being able to make enough of the hormone insulin, which is in full demand during pregnancy.


Candida albicans—more commonly known as yeast—is a fungus found in all bodies, pregnant or not. Thrush develops when there is an overgrowth of yeast, and that’s what causes a dry, “cottony” feeling in the mouth.

Other causes include:


Are there other health issues linked to dry mouth during pregnancy?

In addition to gestational diabetes, experiencing dry mouth can indicate some other conditions, including a common blood disorder called anemia and high blood pressure.

If you’re pregnant and experiencing dry mouth, you should always talk to your physician even if the symptoms appear subtle and aren’t causing any pain.

This is good information to share with my family members and friends as well. I can relate to that thing about having dry mouth caused by diabetes. I know that feeling as I am diabetic myself. Drinking more water does help a lot! I did not know though that having a fungal infection can cause dry mouth too.
