SYNOPSIS“Whole body composition” was investigated in 30 people subject to alcohol‐induced migraine. The control group was 30 people matched for age, sex, height and weight, who were not subject to migraine and who consumed moderate amounts of alcohol. The following were evaluated: anthropometric data, alcohol intake in grams per day, total body water, fat‐free mass, fat mass, and body mass index (kg/m2). Two methods of measurement were used: skin fold thickness evaluation, and bioelectric impedance assay (BIA). BIA is a non‐invasive method based on the principle that lean tissues conduct a low frequency alternating current of electricity better than do fatty tissues.Body mass index was increased in the alcohol‐induced migraine patients (p<0.04), as was fat mass, (p<0.03) as evaluated by skin fold measurements. Bioelectric impedance assay demonstrated a slight total body water increase in alcohol‐induced migraine patients (p<0.07).Possibly, if this total body water increase was reflected at the neuronal level, the bioelectric properties of the migrainous brain may be altered, thus creating a hypothetical link with the phenomenon of spreadi
