Physical activity and physical function changes in obese individuals after gastric bypass surgery

Area of Science:

• Bariatric Surgery
• Metabolic and Bariatric Surgery
• Surgical Weight Loss

Background:

• Limited understanding of gastric bypass surgery (GBS) effects on physical activity and function.
• GBS is a common bariatric procedure for significant weight loss.

Purpose of the Study:

• To assess changes in physical activity, physical function, and quality of life after GBS.
• To explore psychosocial factors related to physical activity post-GBS.

Main Methods:

• Longitudinal study of 20 patients before and 3 months after GBS.
• Assessed physical activity via recall and pedometry.
• Evaluated physical function using 6-minute walk test and Short Physical Performance Battery.

Main Results:

• Significant improvements in 6-minute walk test, Short Physical Performance Battery, and SF-36 scores.
• Average daily steps increased significantly; overall physical activity showed modest gains.
• Reduced self-reported pain in low back, knee, and foot/ankle areas.

Conclusions:

• GBS leads to significant improvements in physical function, quality of life, and pain reduction.
• Modest increases in physical activity observed, with notable rise in daily steps.
• These findings highlight key clinical benefits of surgical weight loss, warranting long-term follow-up.
