Dry Mouth and Pregnancy

Would it be surprising to know that 20% of the world suffers from xerostomia, and of that, pregnant women make up a certain percentage? It’s true.

Pregnancy is supposed to be a time of excitement and joy, but for many, it is also a time of uncomfortable dry mouth symptoms that include a constant sore throat, trouble speaking, and more. Unfortunately, dry mouth is actually very common during pregnancy. It is usually present during the first trimester and happens more frequently at night.


What causes pregnancy-related dry mouth?

Dry mouth occurs during pregnancy for several reasons. Below are some of the most common causes:

  • Gestational diabetes 

Only occurring during pregnancy, gestational diabetes causes high blood sugar. It is a result of the body not being able to make insulin which is in full demand during pregnancy.

  • Thrush

Scientifically speaking, thrush is an overgrowth of the fungus Candida albicans which is present in all bodies. The problem begins when there is an overgrowth. This happens when the immune system is compromised. Thrush is known to cause a dry, “cottony” feeling in the mouth.

  • Increased blood production

To accommodate the growing body, pregnant women produce more blood than women who are not pregnant. When blood production increases, water is retained and that is what causes dry mouth. Not to mention, the body expels more fluids when there is an increase in blood production and that can exacerbate symptoms.

Other causes include:

  • Sleep disturbance
  • Side effects of medication
  • Increased metabolic rates
  • Hormonal changes
  • Dehydration



  • Constant sore throat
  • Trouble swallowing
  • Dryness inside the nose
  • Burning feeling in the throat or mouth
  • Trouble speaking
  • Hoarseness
  • Change in sense of taste
  • Tooth decay
  • Headaches
  • Metallic taste in the mouth
  • Hot flashes
  • Indigestion
  • Cracked lips

Other associated health issues

In addition to gestational diabetes, experiencing dry mouth may indicate one or more other conditions, including anemia and hypertension (high blood pressure).

Women experiencing dry mouth during pregnancy should always talk to their physician, even if the symptoms aren’t causing them pain.
