Postpartum headache.

Headache is a common puerperal complaint. A wide variety of factors can be involved, ranging from hormonal shifts, physiological changes, and peripartum procedures that may precipitate, worsen, or cause troublesome headache. The differential diagnosis of postpartum headache is broad and potentially daunting to the various clinicians caring for the postpartum patient. It often requires further neurological consultation or imaging to resolve. This review will focus on the main causes of postpartum headache, their incidence, and clinical presentation. Causes of postpartum headache that will be covered include benign primary headache disorders such as migraine and tension type headache as well as secondary headache disorders such as postdural puncture headache, stroke, and venous sinus thrombosis. A structured approach to headache evaluation in the postpartum patient will be presented to help differentiate the possible causes of headache.
