Is constipation common in the early stages of pregnancy?

Patient's question:

No

Doctor's answer:

In the early stages of pregnancy, constipation may occur. This is due to reduced secretion of gastric acid and pepsin, prolonged gastric emptying time, weakened intestinal peristalsis, and prolonged retention of feces in the large intestine, leading to constipation. It often causes or exacerbates hemorrhoids.
