Importance of Exercise After Bariatric Surgery

Exercise after bariatric surgery is not a luxury; it is an essential part of the procedure’s success, maintaining weight loss, preventing sagging, and restoring fitness and vitality in the long term.

When exercise is managed with a well-planned and gradual approach after sleeve gastrectomy or gastric bypass, it becomes your primary ally in achieving a toned body and better health, rather than simply a lower number on the scale.

Exercise after bariatric surgery is just as important as the surgery itself, but it should be performed according to a clear program under the supervision of a doctor and a specialized trainer, especially during the first few months.

Key Benefits of Exercise After Bariatric Surgery:

• Reducing sagging and tightening the skin as weight is lost, especially when combining cardio exercises with light resistance training.
• Improving blood circulation, accelerating wound healing after surgery, and reducing the risk of blood clots.
• Increasing calorie burn and improving metabolism while following the prescribed post-operative diet.
• Strengthening muscles and joints and protecting the bones after significant weight loss.
• Improving psychological well-being and helping overcome anxiety and depression after surgery through the release of endorphins, which are associated with feelings of happiness.

How to Exercise After Bariatric Surgery

Dr. Mohamed Matar explains that exercise after bariatric surgery should begin very gently and then progress gradually, with the details varying from one patient to another depending on the type of surgery and overall health condition.

1. Walking

Light walking inside the home or along the corridors can be started after surgery as permitted by the surgeon, often within the first 24 hours, to help expel gas and reduce the risk of blood clots.

During the first few weeks, it is recommended to walk for 20–30 minutes a day, or at least 30 minutes three times a week, gradually increasing the duration and speed according to your ability.

2. Swimming

Swimming or water exercises can be started after ensuring that the wounds have healed, usually after 10–14 days, as determined by the doctor.

Swimming is one of the best exercises after sleeve gastrectomy and gastric bypass because it engages most of the body’s muscles while placing less stress on the joints.

3. Body-Toning and Resistance Exercises

Body-toning and light resistance exercises can usually be introduced from the sixth or seventh week after surgery, provided that the surgeon approves.

At first, the weights should be very light, or body weight alone can be used, focusing on 12–15 repetitions per set and gradually increasing the load.

Light cardio exercises, such as using a stationary bike or brisk walking, are also recommended within the limits set by the doctor and trainer to preserve muscle mass and increase calorie burn.

Exercises to Avoid After Surgery

In general, there are exercises that should be avoided during the first few months after bariatric surgery:

• Lifting heavy weights, especially exercises targeting the abdominal and back muscles at the beginning.
• Intense abdominal exercises such as prolonged planks, vigorous crunches, or machines that place direct pressure on the abdominal wall.
• Strenuous sports or activities involving strong physical contact or a risk of falling, such as judo and some combat sports.
• These activities, if appropriate, should only be introduced at much later stages and based on a joint decision between the doctor and trainer after complete recovery and sufficient core muscle strength.

Dr. Mohamed Matar’s Tips for Exercising After Bariatric Surgery

To ensure your safety and maximize the benefits of exercising after bariatric surgery, Dr. Matar recommends the following:

• Start gradually| Begin with simple exercises (walking and breathing exercises), then slowly increase the intensity and duration of the exercises until you reach a normal level of activity.
• Progress through different types| Start with walking, then add swimming or cycling, and after a few weeks, add light resistance exercises to tone the body.
• Divide exercises into sets| Discuss with your trainer how to divide each exercise into 2–3 sets of 12–15 repetitions instead of exerting significant effort all at once.
• Stop if you experience unusual pain| If you experience joint pain, significant tension around the wounds, or dizziness, you should inform your trainer and doctor so the program can be adjusted or certain exercises stopped.
• Change the program every 4–6 months| It is preferable to change your exercise plan periodically to avoid boredom, stimulate the body more effectively, and maintain your results.

When Can I Start Exercising After Sleeve Gastrectomy?

It is recommended to begin light walking (several short sessions throughout the day) during the first 24 hours after sleeve gastrectomy to prevent blood clots and improve breathing.

-From the first week| Simple walking inside the home several times a day.

-From the second to the fourth week| Gradually increase walking time to 15–30 minutes per day, along with light breathing exercises.

-After 4–6 weeks| More structured exercises can be started (brisk walking, a stationary bike, and some light resistance exercises) after receiving the doctor’s approval.

How Long Can I Exercise After Surgery?

The medium-term goal after sleeve gastrectomy or gastric bypass is to reach:

At least 150 minutes of moderate-intensity physical activity per week (such as brisk walking), equivalent to about 30 minutes a day for 5 days a week.

This can be divided into 3 weekly sessions of 40–45 minutes according to your schedule, while allowing for one or two rest days or days of light activity.

Consistency is more important than intensity; regular daily movement is better than occasional strenuous exercise.

How Can I Speed Up Weight Loss After Bariatric Surgery?

Exercise after sleeve gastrectomy or gastric bypass is an effective way to accelerate and improve weight loss, provided that it is combined with other healthy habits:

• Strictly following the therapeutic diet (especially adequate protein intake, drinking sufficient amounts of water, and avoiding excess sugars and fats).
• Walking daily from the first week, then gradually increasing activity to include cardio and light resistance exercises.
• Getting 7–8 hours of quality sleep, as sleep affects hunger and satiety hormones as well as fat burning.
• Continuing follow-up with Dr. Matar and the nutrition team to adjust the program according to changes in weight and avoid prolonged weight plateaus.
• In this way, exercise helps preserve muscle mass and increase calorie burn, reducing the likelihood of sagging and weight regain.

What Happens If I Exercise Too Early After Surgery?

Exercising too soon, especially strenuous exercises or weightlifting, may cause:

• Pressure on the internal or external wounds, delaying healing or causing them to reopen.
• An increased risk of developing a hernia in the abdominal wall or around the surgical incisions.
• Severe abdominal or back pain, and possibly bleeding or complications requiring medical intervention.

Therefore, you should follow the timeline established by your surgeon and avoid being carried away by enthusiasm or following unqualified advice online or from gym friends.
