Women who are in the first trimester of pregnancy mostly experience the symptoms of dry mouth syndrome. During pregnancy, women need a lot of water for the developing fetus which causes dry mouth. Read more about causes of dry mouth

The symptoms of dry mouth in pregnant women mostly appear during the night.

What are the Symptoms of Dry Mouth in Early Pregnancy?

Women with the dry mouth during pregnancy often experience the following symptoms:

  • Problems in digestion (indigestion)
  • Hot flashes
  • Change in taste
  • Trouble in speaking due to lack of moisture in the mouth
  • Dry nose
  • Sore throat
  • Hoarseness

What Causes Dry Mouth During Pregnancy?

Almost all women experience dry mouth symptoms during pregnancy especially during the early stage pregnancy (first trimester).

Following are some of the potential causes of dry mouth in early-stage pregnancy:

Gestational Diabetes

Some women during pregnancy suffer from temporary diabetes called gestational diabetes which goes away after the childbirth.

During gestational diabetes, there is an increase in the blood sugar levels as the body is unable to produce sufficient insulin. High blood sugar levels result in extreme thirst, frequent urination, and fatigue which contribute to the symptoms of dry mouth.

Side Effects of Drugs

During pregnancy, some women have to take various drugs like antidepressants, bronchodilators, diuretics, etc.

These drugs may lead to various side effects like dry mouth which becomes sometimes very annoying, but you should not stop these medications without a doctor’s suggestion.

Increase in Blood Volume

During pregnancy, women often experience an increase in the amount of blood flow with its peak volume almost higher than in a non-pregnant woman. Due to this increased blood volume, the kidneys work more actively which in turn results in frequent urination and dehydration, all this ultimately results in dry mouth.


Increased blood flow in pregnancy results in dehydration in women and even taking normal regular eight glasses of water doesn’t quench their thirst.

Pregnant women often feel dehydrated due to frequent urination which results in dry mouth.

High Metabolic Rate

Pregnancy increases the rate of various cellular and metabolic processes in the body such as energy production, breaking down the food, etc. As a result, the body consumes the water present in the body, which should be replenished regularly.

Due to excess consumption of water in the body and loss of water in the form of urine, the water in the body is not replenished due to which the women feel a dry mouth.


An overgrowth of a fungus “Candida albicans” in our mouth is called thrush. Normally, everyone has some growth of this fungus in mouth but if there is any abnormality in our immune system, this fungus grows out of range which results in increased thrush.

Some women experience immune-related issues in pregnancy and therefore develop oral thrush. This oral thrush causes dry mouth in such women with a cottony feeling in their mouths.

Sleep-Related Issues and Breathing Problems

Pregnant women often suffer from sleep-related issues like sleeplessness and breathing problems like sleep apnea and snoring.

Snoring and sleep apnea can make you breathe with open mouth during sleeping. This open mouth breathing reduces the saliva production which causes dry mouth.

Changes in Hormone Levels

The fluctuating hormone levels during pregnancy may also reduce the production of saliva which causes dry mouth.

Vomiting and nausea are very common in pregnant women. Vomiting results in fluid loss from the body and creates an acidic environment in the mouth. If the saliva in the mouth is not enough to flush out the acidic fluids, it may result in dry mouth.

Lifestyle Changes

Some life-style changes during pregnancy like alcohol consumption, cigarette smoking, using tobacco products, drinking caffeine-containing beverages, having spicy foods, and mouth breathing may also cause dry mouth.

Anxiety in pregnancy is also found to relate to dry mouth. Read about the association between anxiety and dry mouth here.
