Despite the continued increase in surgical procedures for weight loss, the dramatic increase in the prevalence of morbid obesity far outpaces the treatments to correct it. As a result, the primary care physician is increasingly more likely to be evaluating patients who are either candidates for weight loss surgery or who have already undergone a weight loss procedure. Unique medical and social situations must be considered when evaluating these patients, and it is anticipated that all physicians will be seeing a greater number of complex or challenging patients.
