Background and purpose

A strikingly increasing number of obese patients causes a great interest in potential medical problems resulting from abnormal body weight. Many conditions are associated with obesity. The severity and risk of migraine may be connected with a body weight. We would like to assess a correlation between body mass index (BMI) and frequency and duration of migraine.

Materials and methods

We collected data of 53 female patients with migraine and 36 healthy persons (25 women) as a control group. Mean duration of migraine attacks and their mean frequency were based on patients’ diaries. The patients reported their height. Weight was measured by the authors. We consequently calculated BMI and performed statistics on SAS 9.2.


The mean BMI of the migraine group was 24.27±4.47. Forty-nine percent of patients had normal BMI (18.5–25), 30% patients were overweight (>25) and 13% were obese (>30). The mean BMI among controls was 22.69±2.96. Eighty-four percent of the control group had normal BMI, 12% was overweight and 5% was obese. An association of BMI in women with frequency of migraine episodes per month occurred remarkable when adjusted for age. Difference of a mean BMI value between the migraine and the control group was nearly statistically significant. Body mass index and duration of the episodes revealed similarly strong correlation.


Increased BMI correlates with frequency of migraine. Its influence on a risk of the headaches and their duration remains to be specified.
