Obesity surgery improves survival, study show

Patients who undergo obesity surgery can significantly improve their chances of survival, a new study has suggested.

However, researchers noted that severely obese patients may be more likely to suffer from stress disorders and recommended that they receive a thorough psychological evaluation before receiving obesity surgery.

The study, which was conducted by researchers at the University of Utah School of Medicine, involved 15,850 patients with an average body mass index (BMI) in excess of 45, half of whom received gastric bypass surgery and half of whom decided against the operation.

Researchers found that the group of obesity surgery patients had a 56 per cent lower death rate from heart disease, 60 per cent lower rate of cancer death, and 92 per cent lower rate of diabetes-related death.

"Reduction in death by any cause, and disease-specific deaths such as coronary heart disease, diabetes and cancer, were significantly reduced in surgery patients compared to the non-surgical control group," concluded Dr Ted Adams, lead author and professor of medicine at the University of Utah School of Medicine.
