Risks of Using Glycerin Suppositories During Pregnancy

As the fetus grows, pregnant women find physical activity increasingly difficult. Combined with prolonged sitting or bed rest in daily life, constipation becomes highly likely. However, constipation during pregnancy is a relatively serious condition; excessive straining during bowel movements increases intra-abdominal pressure, potentially compromising fetal stability. Glycerin suppositories (commonly known as “Kaisailu” in China) soften stool and stimulate nerve endings in the rectal wall to facilitate defecation, primarily serving as a treatment for constipation. So, what are the potential risks of using glycerin suppositories during pregnancy? Below, we address this question.

Risks of Using Glycerin Suppositories During Pregnancy

1. Risk of Dependency

Glycerin suppositories promote bowel movements mainly by stimulating the intestinal wall, thereby triggering a defecation reflex. Frequent use increases the frequency of rectal stimulation, gradually reducing rectal sensitivity. Once the body adapts to the medication, the natural defecation reflex may diminish or disappear entirely. This is especially problematic for pregnant women who already suffer from chronic hard, scanty stools; long-term reliance can worsen constipation, leading to habitual constipation and further compromising overall health.

2. Potential Impact on Fetal Health

The two most common types of glycerin suppositories currently available are mannitol-based and glycerol-based formulations. Although their active ingredients differ, both work primarily by softening stool and stimulating the intestinal wall to induce defecation. Occasional, one-time use of glycerin suppositories for constipation during pregnancy is generally considered safe. However, frequent use may expose the developing fetus to potential adverse effects from the medication’s components; therefore, repeated or routine use is not recommended.

Additional Information: Managing Constipation During Pregnancy

1. Dietary Adjustment

Pregnant women should consume more fresh vegetables and fruits to ensure adequate vitamin intake. Increasing dietary fiber intake is also beneficial, as fiber helps alleviate constipation by promoting digestive juice secretion, enhancing intestinal motility, softening stool, and facilitating bowel movements. Additionally, spicy and irritating foods should be avoided, as they may impair digestion and contribute to stool dryness.

2. Moderate Walking

Walking improves systemic blood circulation and stimulates intestinal peristalsis, thereby aiding bowel movements. Abdominal massage may also help enhance gastrointestinal motility and relieve constipation. However, it is advisable to perform such maneuvers only under medical guidance to ensure safety.

3. Adequate Hydration

Dehydration during pregnancy causes food residue to accumulate and harden within the intestines, exacerbating constipation. Consistent and sufficient water intake helps maintain stool consistency and promotes regular bowel movements. In late pregnancy, maintaining optimal hydration supports gastrointestinal motility, shortens intestinal transit time, and effectively alleviates constipation.

Above is an overview of the potential risks associated with glycerin suppository use during pregnancy. We hope this information proves helpful.
