Subcutaneous Fat
Conditions
Brief summary
The purpose of this study is to provide information about human subcutaneous fat thickness at different anatomic sites on the body by measuring these thicknesses with a diagnostic ultrasound and also by correlating patient perceptions of body image with measured fat distribution. Subjects currently living in the Chicago metropolitan area and meet inclusion/exclusion criteria will be considered for enrollment.
