Drinking excessive coffee or other caffeinated beverages may be a trigger for migraines amongst individuals susceptible to these serious headaches, a brand-new research study recommends.
The research study scientists discovered that, amongst individuals with routine migraine headaches, taking in a minimum of 3 caffeinated beverages a day was connected to a greater probability of experiencing a migraine on that day or the following day. Nevertheless, taking in just one or 2 caffeinated beverages a day was normally not connected with migraines, the research study discovered.
Although lots of people anecdotally report that caffeine tends to trigger their migraines, couple of extensive research studies have actually analyzed this link. Undoubtedly, the brand-new research study, released today (Aug. 8) in The American Journal of Medication, is among the very first to analyze whether everyday modifications in caffeine consumption are connected to the beginning of migraines.

“Remarkably, regardless of some clients with episodic migraine believing they require to prevent caffeine, we discovered that drinking one to 2 portions [per] day was not connected with greater danger of headache,” research study senior author Dr. Suzanne Bertisch, an assistant teacher at Harvard Medical School and a medical detective in the Department of Sleep and Circadian Conditions at Brigham and Women’s Health center in Boston, stated in a declaration. Still, more research study is required to validate the findings; “but it is an important first step,” Bertisch stated.
The function of caffeine in setting off migraine headaches may be especially intricate, the authors stated, since its effect depends upon just how much individuals take in and how frequently. Caffeine may trigger an attack, however it might likewise have a pain-relieving result, they stated.
In the brand-new research study, the scientists evaluated info from almost 100 grownups who were identified with episodic migraines, which suggests they experienced migraine headaches a minimum of two times a month, however no greater than 15 times a month. (Individuals with 15 or more migraine headaches each month have actually a condition called “chronic migraine.”)
Individuals submitted an online study two times a day for 6 weeks to tape their caffeine consumption — consisting of the variety of portions of coffee, tea, soda and energy beverages they took in — and whether they experienced a migraine headache that day.
Usually, individuals reported experiencing about 8 migraines throughout the six-week research study duration. All of the individuals reported consuming caffeine a minimum of as soon as throughout the research study duration, and usually, they took in about 8 portions each week.
For each individual, the scientists compared reports of migraines on the days they took in caffeine with reports of migraines on the days they did not take in caffeine.
In general, individuals were most likely to experience migraine headaches on days they took in 3 or more caffeinated drinks, compared to days they didn’t take in caffeinated drinks. However there wasn’t a link in between migraine headache and usage of a couple of caffeinated drinks.
Nevertheless, amongst individuals who hardly ever taken in any caffeine, even one to 2 portions of caffeine increased the possibilities of having a headache on that day, the authors stated.
The findings held even after the scientists took into consideration other aspects that might trigger migraines, consisting of alcohol usage, tension, workout and sleep deprivation.
It’s possible that some individuals tended to take in caffeinated beverages after their migraines began. To attempt to dismiss such “reverse causation,” the scientists took a look at the link in between caffeine usage on an offered day and migraine headaches on the following day. Their findings were comparable: Drinking a minimum of 3 caffeinated drinks was related to an increased danger of migraine on the following day.
Still, the research study was unable to analyze whether aspects such as the kind of caffeinated drinks, overall quantity of caffeine or time of day of usage impacted the danger of migraines, therefore more research study is required to examine this, the authors stated.
