Which of the following gastrointestinal discomforts is most likely caused by relaxation of the lower esophageal sphincter by progesterone?

Goodell’s signis the softening of the cervical tipobserved around 6–8 weeks of pregnancy. It is caused by increased vascularity, hyperplasia, and hypertrophyof cervical glands due to estrogen and progesterone. Normal cervical tissue is firm, but with increased blood flow and edema, the cervix becomes softand pliable.

Rationale for correct answer

3.Goodell’s sign results from increased vascularity leading to engorgement, along with hyperplasia and hypertrophy of cervical glands. Estrogen increases blood flow and stimulates cervical tissue changes, causing the softening of the cervix detected on pelvic exam.

Rationale for incorrect answers

1.Decreased vascularity would make the cervix less perfused and firmer, not softer. Goodell’s sign specifically results from increased blood flow, not reduction.

2.Increased collagen content makes tissue more rigid and firm. In pregnancy, cervical collagen is remodeled and partially degraded, contributing to softening, not increased firmness.

4.Uterine contractions do not cause early cervical softening. Contractions influence cervical effacement and dilation during labor, but Goodell’s sign occurs in early pregnancy before labor begins.

Take home points

• Goodell’s sign is cervical softening detected at 6–8 weeks of pregnancy.

• It results from increased vascularity, hyperplasia, and hypertrophy of cervical glands.

• Increased collagen would firm the cervix, but in pregnancy collagen is remodeled for softness.

• Uterine contractions affect dilation in labor, not early pregnancy softening.

Constipation in pregnancyis common due to hormonal and mechanical factors. Progesteronerelaxes smooth muscle, slowing colonic transit, while the enlarging uterus compresses the intestines. Normal bowel movement frequency ranges from 3 times/day to 3 times/week. Low fiberintake (<25 g/day), reduced activity, and inadequate hydrationworsen symptoms. Typical clinical features are infrequent stools, straining, and hard stool consistency. Preventive strategies include dietary fiber >25–30 g/day, fluid intake >2 L/day, regular exercise, and meal pattern adjustment.

Rationale for correct answers

1.Increased fiber intake enhances stool bulk and water retention, stimulating peristalsis. Daily intake of 25–30 g is recommended for pregnant women to prevent constipation.

3.Regular exercise improves bowel motility by stimulating colonic activity. Activities like walking 30 minutes daily are safe and effective in pregnancy.

5.Promoting small, frequent meals helps regulate digestion, prevents gastric overfilling, and maintains steady bowel function. This supports peristalsis and reduces bloating.

Rationale for incorrect answers

2.Reducing fluid intake worsens constipation. Adequate hydration (≥2 L/day) softens stools and supports normal bowel function. Low fluid intake results in harder stools and straining.

4.Avoiding stool softeners is incorrect. Stool softeners such as docusate sodium are considered safe in pregnancy and may be used when lifestyle measures are insufficient. They reduce straining without systemic absorption.

Take home points

• Progesterone-induced smooth muscle relaxation slows bowel transit in pregnancy.

• Adequate fiber, fluids, and exercise are first-line preventive strategies.

• Small frequent meals regulate digestion and reduce bloating.

• Stool softeners are safe in pregnancy if lifestyle changes are inadequate.
