  • Too much coffee per day may trigger migraine

"Based on our study, drinking one or two caffeinated beverages in a day does not appear to be linked to developing a migraine headache, however, three or more servings may be associated with a higher odds of developing a headache", noted lead investigator Elizabeth Mostofsky, ScD, Cardiovascular Epidemiology Research Unit, Beth Israel Deaconess Medical Center, and Department of Epidemiology, Harvard T.H. Chan School of Public Health, Boston, MA, USA.

"There's been a lot of anecdotal evidence about the effect of caffeine on the risk of migraine", Mostofsky told MedPage Today. However, it may even have an ache-relieving impact, they said. All reported having caffeinated beverages on at least one day during the study, with an average of 7.9 servings per week."To date, there have been few prospective studies on the immediate risk of migraine headaches with daily changes in caffeinated beverage intake".

The experiment involved 98 people with episodic migraines. Every day, participants reported the total servings of caffeinated coffee, tea, soda and energy drinks they consumed, as well as filled out twice daily headache reports detailing the onset, duration, intensity, and medications used for migraines since the previous diary entry.

The patients also provided detailed information on other common migraine triggers: medications, alcoholic drinks, level of physical activity, symptoms of depression, psychological stress, sleep habits, menstrual cycles, etc.

There was no link between migraine headache and consumption of one or two caffeinated beverages, except for those who nearly never have caffeine.

The volunteers had to report their caffeinated beverage consumption every morning and evening for at least six weeks. Owning to the self-matched analysis, it was observed that significant factors such as age, sex, individual demographic, behavioral and environmental factors could be eliminated.

The study seemingly confirms medical professionals' suspicions that increased caffeine intake could trigger migraines, per the news outlet.

"One serving of caffeine is typically defined as eight ounces or one cup of caffeinated coffee, six ounces of tea, a 12-ounce can of soda and a 2-ounce can of an energy drink", commented Mostofsky.

The paper states: We can not assess whether the association varies by beverage type, adding: We can not quantity the amount [of caffeine] associated with heightened risks.

For those who experience episodic migraine, one to two servings of caffeinated drinks were not associated with headaches on that day. Moreover, almost a quarter of people who reported having four or more migraine headaches per month were now using opioids to treat their pain, and more than half of these respondents reported taking opioids at least once to treat a migraine headache. A new study by Harvard researchers seems to show that it takes a lot of caffeine to actually set off a painful episode. "So, when asking about caffeine consumption, it is important to inquire about the size of the serving, as well as the amount of caffeine added to the cup".

The role of caffeine in triggering migraine complications could also be significantly complex, the authors stated, as a result, its impact depends on how much coffee people consume and how often.

"People may consume caffeine and then have a caffeine withdrawal headache or they may have a headache and then try to self-treat with the caffeine", Minen said.
