Condition

Constipation

Infrequent, hard, or difficult-to-pass stools.

See a clinician

Some causes of constipation need medical care, not self-treatment. Seek help for any of these:

  • Rectal bleeding, unexplained weight loss, or new constipation after age 50
  • Vomiting, severe bloating, or no passage of gas (possible obstruction)

What may help

Remedies studied for constipation, ranked by strength of evidence.

  • B
    Psyllium (soluble fiber) supplement

    A bulk-forming laxative that increases stool frequency and softens stool.

  • B
    Senna herb

    Reliably relieves constipation by stimulating bowel movement.

Fluids, fiber, and activity come first. Psyllium (bulk), magnesium (osmotic), and senna (stimulant) are all well-supported over-the-counter options.
