Dizziness During Period

Feeling dizzy or lightheaded during your period is more common than often discussed. It can be caused by blood loss, prostaglandins, low blood pressure, or low blood sugar.

What causes it

Heavy menstrual bleeding can cause temporary anaemia or low blood pressure, leading to dizziness. Prostaglandins can cause nausea and light-headedness. Vasovagal responses to cramping pain can also cause dizziness or fainting.

How to track it

Log when dizziness occurs relative to flow days and cramping. Note whether it is worse when standing up quickly (postural hypotension) or more constant. Also track how heavy your flow is on those days.

When to see a doctor

See a doctor if dizziness is severe, if you faint or nearly faint, if it is accompanied by very heavy bleeding, or if it is a new or worsening symptom.
