This prospective cohort observational study found that about 53.4% of patients had migraine attacks on the first day of Ramadan, mostly while fasting. The number of migraine attacks dropped significantly in both the second and third 10-day periods of Ramadan (median 1, interquartile range [IQR] 0-2.25; median 1, IQR 1-3, respectively) compared with the first 10 days (median 3, IQR 1-5). This potentially exacerbating effect on migraines that intermittent fasting can have was mostly limited to the first 10 days of Ramadan and then dropped off sharply. Compared with the month before, Shaaban, (median 3, IQR 1-6 P = .009), migraine attack frequency was significantly increased during Ramadan (median 4, IQR 2-7).
