From the Research

Hypersalivation during the first trimester of pregnancy is primarily caused by hormonal changes, particularly increased estrogen and human chorionic gonadotropin (hCG), which stimulate the salivary glands 1.

Causes and Triggers

The exact cause of hypersalivation in pregnancy is not fully understood, but it is believed to be related to the hormonal fluctuations that occur during this period.

  • Increased estrogen levels: Estrogen can stimulate the salivary glands, leading to an increase in saliva production 1.
  • Human chorionic gonadotropin (hCG): hCG is a hormone produced during pregnancy that can also stimulate the salivary glands, contributing to hypersalivation 1.

Management and Treatment

To manage hypersalivation during pregnancy, try the following:

  • Eat small, frequent meals to reduce symptoms of morning sickness and hypersalivation 2.
  • Stay well-hydrated with water or ice chips to thin out saliva and make it easier to swallow 2.
  • Chew sugar-free gum or suck on hard candies to stimulate swallowing and reduce saliva production 2.
  • Brush teeth frequently and use alcohol-free mouthwash to reduce saliva production and improve oral comfort 2.

Medications and Supplements

For severe cases of hypersalivation, medications are generally avoided during pregnancy, but your healthcare provider might recommend:

  • Vitamin B6 supplements: Vitamin B6 has been shown to be effective in reducing symptoms of morning sickness and hypersalivation 3, 2.
  • Antihistamines like doxylamine: Doxylamine is an antihistamine that can help reduce symptoms of morning sickness and hypersalivation 3, 2. It is essential to consult your healthcare provider before taking any medications or supplements during pregnancy.

Quality of Life and Morbidity

Hypersalivation during pregnancy can be uncomfortable and affect a woman's quality of life. However, it is not typically harmful to the mother or the baby and usually resolves on its own after the first trimester 1. If excessive saliva causes significant distress or is accompanied by severe nausea and vomiting, consult your healthcare provider for personalized recommendations.
