Migraine is a disorder that affects about 1.04 billion adults worldwide. Three cups of coffee consumed a day are enough to help trigger a migraine, suggests a new study released Thursday by the Press Association.
In people with episodic migraines, one or two servings of caffeinated drinks were not associated with the occurrence of headaches that day, according to a study published in the American Journal of Medicine. But three or more portions may increase the risk of migraines on the same day or the next.
"Based on our study, consumption of one or two caffeinated drinks per day does not appear to be associated with the occurrence of a migraine, but three or more portions may be related to the increased risk of developing a migraine," said the lead author. of research, Elizabeth Mostofsky.
A group of specialists from Boston, Massachusetts, from Beth Israel Deaconess Medical Center (BIDMC), Brigham and Women's Hospital and Harvard T.H. Chan School of Public Health (HSPH) has evaluated the role of caffeine drinks as a potential migraine trigger.
"While some potential triggers – such as sleep deprivation – can only increase the risk of migraine, the role of caffeine is particularly complex because it can trigger an attack, but it can also help control symptoms. The impact of caffeine depends on both dose and frequency, but because there are few studies on the immediate risk of migraines after the intake of caffeine drinks, the evidence is too limited to make dietary recommendations for people with migraines, ”noted Mostofsky.
The study participants, 98 adults with frequent episodes of migraine, completed in an electronic journal every morning and evening for at least six weeks the total number of caffeine, tea and energy drinks consumed and details about headaches, including the time of onset, intensity and medications used, writes Agerpres.
A serving is defined by about 225 grams of caffeine coffee, 170 grams of tea, a 0.33 ml box of caffeinated soft drink or a 50 gram box of energy drink.
Scientists said that these portions contained between 25 and 150 milligrams of caffeine, which is why they were unable to calculate the amount of caffeine associated with increased migraine risk.
In the case of people who rarely drink caffeine drinks, even one or two servings may increase the risk of migraine on that day, the study shows.
The baseline data indicated that participants presented, on average, five episodes of headaches per month – and 66% of them routinely consumed up to two servings of caffeinated drinks per day. About 12% consumed three or more cups.
During the six weeks of the research, the participants presented an average of 8.4 episodes of headaches. All participants reported drinking caffeinated beverages at least one day during the study, with an average of 7.9 servings per week, the Press Association notes.
