Worsening of migraine headache with fasting Ramadan

Fasting is known as a trigger for migraines. Muslims fast 1 month every luminal year. We aimed to study the impact of The Holy month of Ramadan on migraine headaches.

This retrospective study included patients diagnosed with migraines according to The International Classification of Headache Disorders, 3rd edition (ICDH-3). Both genders, aged between 18 and 65 years were included. The impact of Ramadan fasting and changing habits during the month of Ramadan was studied. The frequency and the severity of migraine attacks, and the number of analgesic days during Ramadan were compared to those during Shaban, the immediately preceding month to Ramadan. The number of breaking fasting due to migraines was reported.

This study identified 293 with migraine with mean age and mean disease duration 37.09 ± 9.36, 12.34 ± 9.27 years respectively. Most of them were females (89.1%). Most of our cohort had changed sleep and food habits during Ramadan (93.2%). The majority of them were dehydrated (89.8%). Most of the patients completed fasting the whole month of Ramadan. A minority (1.7) could not tolerate fasting the whole Ramadan due to intolerable migraine headaches and 36.5% broke their fasting for some days during Ramadan. Most of our cohort (82.3%) continue on the same management plan for migraines during Ramadan. During the month of Ramadan, the patients had a significant increase in migraine days of 10.42 ± 7.98 compared with 6.90 ± 6.55 migraine days during the previous month (p < 0.001). Also, days of analgesic use (11.32 ± 10.46 versus 6.11 ± 6.69; P < 0.001) and migraine severity (7.46 ± 2.39 versus 6.84 ± 2.25; P < 0.001) were significantly increased during Ramadan compared with Shaban. In multivariate analysis, change in sleep and feeding habits together with non-modification of the treatment plan before Ramadan significantly predict breaking fasting due to worsening of migraine headache (p value = 0.041, p value = 0.025; respectively). The majority of our cohort (75.4%) reported that migraines interfered with their daily activities due to fasting during Ramadan.

Change in sleep and food habits along with dehydration make Migraine frequency and severity worse during Ramadan fasting. Physicians should educate migraine patients who fast to manage their headaches and habits before starting fasting.
