Constipation Management in Pregnant Women Taking Oral Iron

Introduction to Constipation Management

The American Gastroenterological Association recommends a hierarchical approach to constipation management in pregnant women, prioritizing dietary modifications, bulk-forming agents, and osmotic laxatives over stool softeners as first-line therapy for iron-induced constipation 1, 2

The American Gastroenterological Association guidelines suggest increasing fiber intake to ~30 g/day, including fruits, vegetables, whole grains, and legumes, to help manage constipation in pregnant women 1, 2
Adequate fluid intake, particularly water, is also recommended to help manage constipation in pregnant women 1, 2
Bulk-forming agents, such as psyllium husk or methylcellulose, are preferred due to lack of systemic absorption and can improve stool viscosity and transit time beyond just bulk 1, 2
Osmotic laxatives, such as polyethylene glycol or lactulose, are safe in pregnancy but may cause maternal bloating 1, 2

Not trying dietary and bulk-forming agents first, which are guideline-preferred and may be more effective, can lead to inadequate management of constipation in pregnant women 1, 2
Using stimulant laxatives due to conflicting safety data can pose risks to pregnant women 1
Excessive fiber intake can cause bloating, worsening patient discomfort 1
