Patients who exercise after undergoing obesity surgery
are likely to boost their rate of weight loss and enjoy an improved quality of life, a new study suggests.
Obesity surgery is widely regarded as the most effective treatment for morbidly obese individuals who have failed to lose weight by other means, such as diet and exercise.
Researchers at the Miriam Hospital's Centres for Behavioural and Preventive Medicine studied nearly 200 patients who underwent gastric bypass surgery at Virginia Commonwealth University.
They classed active patients as those who did at least 200 minutes of weekly physical activity, such as walking and participating in other moderately intensive activities.
Publishing their findings in Obesity journal, the researchers discovered that patients who were inactive prior to obesity surgery but who subsequently increased their activity levels tended to lose more weight.
More than two thirds of those who became very active one year after surgery lost an extra 13.2 lbs and reduced their body mass index by an additional two index points.
They also reported a higher quality of life in terms of general health, energy levels and depression.
Lead author Dr Dale Bond, of The Miriam Hospital's Centres for Behavioural and Preventive Medicine, commented: "Bariatric surgery is quickly emerging as a standard treatment for severe obesity, although weight loss outcomes vary."
He concluded that exercise may promote enhanced weight loss and greater improvements in quality of life following obesity surgery.
