Gastrointestinal System

Reflux esophagitis (heartburn):

■ Enlarging uterus displaces the stomach above the esophageal sphincter and causes increased intragastric pressure.

■ Progesterone causes a relative relaxation of the esophageal sphincter.

■ There may also be reflux of bile into the stomach due to pyloric incompetence.

Constipation may occur secondary to progesterone, which relaxes intestinal smooth muscle and slows peristalsis.


■ Increases in size

■ Empties more slowly

■ Cholestasis, probably due to a hormonal effect since it also occurs in some users of oral contraceptives (OCs) and hormone replacement therapy (HRT)
