Homerton bariatric service: physiotherapy essential advice
Why is exercise important before and after bariatric surgery?
Physical activity plays a vital role in your bariatric surgery journey – from preparing your body for surgery to helping ensure a safe recovery, and supporting long-term weight management. Below we have outlined the advised recommendations for a safe and successful surgery outcome. If you are struggling to meet these guidelines, it is important you discuss this with a member of the Bariatric team to establish if any further support is required.
Before Surgery – Get Your Body Ready
After Surgery – Keep Moving, Stay Strong
Goals:
Improve fitness for surgery (reduces anaesthetic risks and surgical complications)
Build muscle strength and stamina to improve post-op recovery
Goals:
Enhance weight loss outcomes
Preserve muscle mass during weight loss
Help reduce risk of weight re-gain
Improve blood pressure, blood sugar and cholesterol
Recommended Activities:
Aim for at least 150 minutes of moderate-intensity exercise per week (e.g., brisk walking, cycling). This can be broken down into 10-minute bouts.
Include strength-building activities at least 2 days a week (e.g., bodyweight exercises, resistance bands)
Reduce sitting time – stand or move regularly throughout the day
Start gradually if you are not active. Every movement counts!
Early Recovery (0–6 weeks):
Start gentle walking as soon as advised – usually within 24 hours
Increase walking time daily (little and often)
Avoid lifting heavy objects for 4–6 weeks
6 Weeks and Beyond:
Gradually return to 150–300 minutes/week of moderate-intensity aerobic activity
Add muscle-strengthening exercises (e.g., resistance training) at least 2 days/week
Risks of Not Exercising
Higher risk of post-surgical complications (e.g., respiratory problems, slower wound healing)
Slower recovery and return to daily activities
Reduced weight loss and higher chance of regaining weight
Loss of muscle mass and physical function
Increased risk of long-term health problems (e.g., type 2 diabetes, heart disease)
