A new study suggests that frequent spells of migraines - those that attack less than every other day - was close to two times as much occurring for obese adults compared to average-weighing people.

The recent findings propose that doctors and patients must know the link of obesity to a rise in incidences of migraine spells, according to lead author Dr. Lee Peterlin from Johns Hopkins University School of Medicine in Baltimore. This will help address the issue before it worsens and result to chronic migraine.

The researchers however are uncertain which is caused by the other, the weight problem or the increased headache attacks. A similar researcher on migraines not part of the study commented that interpretation must be preceded with caution.

In an attempt to answer the question of whether weight is a factor to semi frequent migraines, the researchers went through data of 3,862 participants in a U.S survey in the early years of 2000s. Out of those data, about 188 were reported to have migraines three to four times a month.

Their initial finding revealed that about 32 percent with recurring migraines were obese, in contrast to those 26 percent of people with no migraines.

Further the researchers found obesity can be linked to 81 percent higher possibility of incidences of frequent migraine attacks. This was after factoring in age and cigarette use.

Peterlin suggests that some probable explanations could answer this link, saying that those body systems which become active when a person experiences a migraine attack also aids in the regulation of appetite levels. In addition, those who suffer from regular headaches may have less active lifestyles or may have regular intake of medications affecting weight.

The researchers admitted that they were unable to fully establish the link between obesity and migraines but have proven that frequent migraines are becoming common.

The study was published in the Sept. 11 issue of Neurology.
