Laxatives are medications that relieve constipation by drawing water into the intestines, softening stool, or stimulating colonic muscle contractions. They are commonly prescribed for occasional constipation, post-surgical recovery, and bowel preparation before diagnostic procedures. The four primary categories—bulk-forming agents, osmotic laxatives, stimulant laxatives, and stool softeners—differ significantly in mechanism, onset time, and risk profile. Prolonged or unsupervised use can cause electrolyte imbalances, dehydration, and rebound constipation that worsens the original problem. Consulting a physician ensures the correct type, dosage, and duration based on your medical history and concurrent medications.
