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

## Goals:

- Improve fitness for surgery (reduces anaesthetic risks and surgical complications)

Build muscle strength and stamina to improve post-op recovery

## 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!

## After Surgery – Keep Moving, Stay Strong

## 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

## 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)
