Background Bariatric surgery leads to resolution of arterial hypertension and diabetes mellitus; isolated reports indicate that response to bariatric surgery is lower in aged patients. The aim of this study was to evaluate the role of age and of duration of obesity on the frequency of co-morbidities in morbid obesity, as well as on improvement of co-morbidities. Methods A total of 837 consecutive patients with known duration of obesity, undergoing gastric banding, were considered for this study; they were divided into quartiles of age and of duration of obesity. Presence of co-morbidities (diabetes mellitus, arterial hypertension, metabolic syndrome), metabolic variables (cholesterol and HDL-C, triglycerides, blood glucose), anthropometric variables, and loss of weight during 24 months were considered. Results Older patients had a higher frequency of co-morbidities; duration of obesity only affected frequency of co-morbidities, but not response to surgery. At logistic regression, duration of obesity had a moderate independent effect on the frequency of diabetes. Older patients lost less weight than younger patients, but diabetes mellitus and arterial hypertension improved to the same extent in patients of different ages, and metabolic syndrome disappeared more in older patients, associated with a greater decrease of blood glucose. Frequency of removal of gastric banding and loss to follow-up were not different in different quartiles of age or in different quartiles of duration of obesity. Conclusion Older patients, despite lower weight loss, have a response to bariatric surgery that is similar to that of younger patients; age and duration of obesity should not be considered as limits to indications to bariatric surgery.
