Hormone headaches (menstrual migraines)
Hormones are responsible for many headaches women experience, sometimes called 'menstrual migraines'.
How are hormones and headaches linked?
Headaches in women, particularly migraines, have been related to changes in the levels of the female hormone oestrogen during a woman's menstrual cycle. Oestrogen levels drop before the start of monthly bleeding.
Premenstrual migraines can happen when the hormones oestrogen and progesterone drop to their lowest levels each month. Experts believe it is the falling levels rather than the levels being low that trigger headaches.
Migraine attacks linked to hormones often disappear during pregnancy.
However, migraines may start during the first trimester of pregnancy.

Over-the-counter painkillers may help relieve menstrual migraine.
Doctors may recommend taking non-steroidal anti-inflammatory drug (NSAID) painkillers like ibuprofen 2-3 days before the period to help prevent migraines and stopping the treatment at the end of the period.
