Over 100 patients with obesity and type 2 diabetes were given bariatric surgery in a randomised, double-blind trial in New Zealand. For patients undergoing either of these surgeries, their depression symptoms remained improved 5 years later, although lessened from what was reported one year after the surgery. The researchers also found that pre-existing depression symptoms did not affect the weight loss achieved 5 years after surgery. The study did not include those with severe clinical depression. The researchers say these findings confirm previous studies that have shown bariatric surgery is generally associated with improved psychological health.
