Frequency Of Migraines During Pregnancy
Many women have migraines for the first time when theyre expecting; others, including women with a history of migraines, get them more often.
Blame your out-of-whack pregnancy hormones, plus all those other pregnancy-related triggers you’re experiencing: fatigue,;tension, blood sugar drops, physical or emotional stress, nasal congestion;and;overheating or a combination of all of these.
That said, some women who have a history of migraines related to their menstrual cycle actually end up getting these headaches less often when theyre expecting, particularly during the second and third trimesters.
Thats because their migraines are likely caused by the “withdrawal” of estrogen that occurs just before menstruation; during pregnancy, estrogen levels remain consistently high.
