Which agent is commonly used postpartum to prevent constipation?

• A. Docusate
• B. Psyllium husk
• C. Bisacodyl
• D. Magnesium citrate

Answer: (A)

The key idea is preventing constipation to protect healing perineal tissue and reduce strain during bowel movements. A stool softener like docusate is used postpartum because it makes stool softer and easier to pass by increasing the water content in it, without stimulating the bowel. This gentle effect lowers the urge to strain, which supports perineal and episiotomy healing and helps avoid hemorrhoids. It’s also safe for breastfeeding.

Psyllium husk adds bulk to stool and requires adequate fluids; while it can help prevent constipation, it can cause gas and isn’t as immediately gentle or routinely used for postpartum prevention as a stool softener. Bisacodyl is a stimulant laxative that increases intestinal movements and can cause cramping—helpful for treating established constipation but not ideal for routine prevention. Magnesium citrate is an osmotic laxative that can lead to diarrhea and electrolyte imbalances, making it unsuitable for routine postpartum prevention.
