Migraine patients treated with anti-CGRP monoclonal antibodies

What This Study Found

Constipation from anti-CGRP migraine therapeutics results from blocking CGRP's physiological role in maintaining intestinal peristalsis, ion/water secretion, and transit through both extrinsic and enteric nerve pathways.

Key Numbers

>50% constipation rate; CGRP drives peristalsis; CGRP drives secretion; CGRP accelerates transit; causes diarrhea exogenously

How They Did This

Narrative review of CGRP's pharmacological actions in the digestive tract, including enteric nervous system function, peristalsis, secretion, and transit studies in animals and humans.

Why This Research Matters

Over 50% of patients on anti-CGRP drugs experience constipation. Understanding why helps clinicians manage this side effect and set proper expectations for patients starting these medications.

What This Study Doesn't Tell Us

Narrative review with no original data. The >50% constipation rate is from real-world surveys, not randomized trials. Individual variation in constipation severity is not well characterized. Management strategies for the constipation are not reviewed.
