WEDNESDAY, June 15 (HealthDay News) -- Being depressed doesn't
reduce the effectiveness of weight loss surgery, a new study
University of Michigan researchers analyzed data from more than
25,469 patients who had weight loss surgery and found that patients
who were depressed or depression-free before the surgery all lost
nearly 60 percent of their excess weight within one year. They also
reported an average 30 percent improvement in quality of life,
including greater mobility, social interactions, family life and
Patients with depression did have a higher rate of minor
complications (4 percent versus 3.3 percent), but there were no
significant differences in major complications between the two
groups. (The average rate of
major complications from weight loss surgery is 4
The study also found that the use of antidepressants by patients
who had depression decreased by about 20 percent (from 72 percent
to 60 percent of patients) one year after weight loss surgery and
remained at that level after three years of follow-up.
The study was slated for presentation Wednesday at the annual
meeting of the American Society for Metabolic & Bariatric
"Depression and anxiety are relatively common among those with chronic diseases like obesity and type 2 diabetes, and these conditions can sometimes interfere with treatment," lead author Dr. Jonathan F. Finks, an assistant professor of surgery at the University of Michigan, said in an ASMBS news release.
"This study suggests bariatric patients suffering from depression can experience health outcomes and quality of life improvements comparable to non-depressed patients. However, doctors and patients still need to consider psychological issues, state of mind and commitment to lifestyle changes after surgery in assessing whether bariatric surgery is appropriate and indicated for any particular patient," he added.
Because this study was presented at a medical meeting, the
findings should be viewed as preliminary until they are published
in a peer-reviewed journal.

Diseases has more about
