Is Dry Mouth While Pregnant a Sign of Gestational Diabetes?

Gestational diabetes occurs only during pregnancy. Its main cause is when the body can’t sufficiently provide a good amount of insulin to maintain healthy levels of blood glucose, and glucose intolerance occurs. This decreased ability of the body to maintain the normal amount of blood sugar enhances during pregnancy, and it’s regarded as the pre-diabetic stage. Of course, one very common symptom of gestational diabetes is dry mouth, just like normal diabetes. However, having dry mouth while pregnant does not mean you have gestational diabetes.

Having a dry mouth is very normal during pregnancy. Your changing hormones and enhanced need for water in the body due to another body growing inside of you may lead to dryness of the mouth. For this reason, regularly brushing your teeth is important because dry mouth during pregnancy can often cause oral health issues like infections, tooth decay, bad breath, or hypersensitivity.

In addition, floss regularly to get rid of brown or black spots, stop bacterial growth, and prevent tooth decay. Use mouthwash specifically to treat any tooth disorders. Although dry mouth itself is not a disease, it is a concerning situation as sometimes it can be a symptom of an underlying health condition that needs treatment.

Why Is My Mouth So Dry During Pregnancy?

There could be many underlying causes of dry mouth during pregnancy. The most common causes experienced among pregnant women are:


During pregnancy, your body needs more water, just like you have other additional nutritional needs. Not only this, but the body loses water fast as the bladder is overburdened due to fetal growth.

Other symptoms experienced among pregnant women due to severe dehydration in addition to dry mouth are:

  • Dark yellow urine
  • Fatigue and exhaustion
  • Constant headache

Distorted sleep cycle:

A disrupted sleep cycle leads to more problems during pregnancy other than just a dry mouth. However, dry mouth during pregnancy is one of the earliest signs that you are not getting enough sleep. Pregnancy brings about sleep changes like over tiredness, sleep apnea, and snoring. This can lead to pregnancy dry mouth, especially at night when you snore or sleep with an open mouth.

Gestational Diabetes:

As already discussed, gestational diabetes occurs during pregnancy. In the US, one out of ten pregnant women get gestational diabetes. It can lead to enhanced blood sugar levels and dry mouth during pregnancy. High blood sugar can also cause an increased urge to urinate, which further leads to severe dehydration and pregnancy dry mouth.


Thrush is characterized by the growth of cottage cheese like lesions inside your mouth, on the areas of the tongue and cheeks. It occurs due to the overgrowth of a fungus called Candida albicans which leads to redness and mouth sores. Women with weak immune systems are more prone to developing thrush.
