*Hormone-related migraine headaches are largely related to changes in levels of estrone glucuronide (EIG). *Studies have shown that in addition to an increase in symptoms for female migraneurs during the menstrual phase (during first 3 days of menses), there are also 3 distinct midcyle (around day 14) phases during which migraines are most prevalent. They are: 1) Late follicular phase (LF) (rapid rise in estrodiol level) 2) Early follicular 1 phase (rapid drop in estrodiol level) 3) Early follicular 2 phase (rapid rise in progesterone level) American Headache Society 49th Annual Scientific Meeting: Abstract 150.
