What Should a Pregnant Woman Do If She Develops Mouth Ulcers?

Pregnancy is an exceptionally important and unique period in a woman’s life. During this time, the mother’s body undergoes significant changes to prepare for fetal development, childbirth, and subsequent breastfeeding—changes that may also bring about certain discomforts, such as recurrent oral ulcers. What should a pregnant woman do if she develops an oral ulcer?

What to Do If a Pregnant Woman Develops an Oral Ulcer

A pregnant woman with an oral ulcer may rinse her mouth with warm saline solution. Additionally, under the guidance of a qualified healthcare provider, she may take anti-inflammatory medications to alleviate oral pain and promote ulcer healing. However, pregnant women should avoid self-medicating, as inappropriate drug use may adversely affect both their own health and fetal development.

Whether oral ulcers in pregnancy affect the fetus depends on the severity and type of ulcer. Mild oral ulcers that do not interfere with eating generally pose no risk to fetal development. However, severe or persistent ulcers can significantly impair maternal nutrition intake, thereby compromising fetal growth. For instance, they may weaken the mother’s immune system, leading to recurrent episodes. Moreover, inadequate nutrient absorption may hinder optimal fetal nourishment, resulting in intrauterine growth restriction or delayed development.

Many pregnant women experience increased appetite and consume more high-protein foods, while often neglecting adequate intake of vegetables and fruits. This dietary imbalance may lead to vitamin deficiencies, contributing to symptoms such as halitosis, oral ulcers, and sore throat—signs commonly associated with “excess stomach heat” in traditional Chinese medicine.
