"Why Do Doctors Recommend Post-Surgery Exercise?"

Why Do Doctors Recommend Exercise After Surgery?

When a person undergoes surgery, whether involving bones, joints, muscles, or internal organs, many people assume they should simply remain in bed and let the body recover on its own. In reality, doctors and physical therapists often recommend that patients “start moving” or “begin light exercise” as soon as it is safe to do so.

How Does Movement Help?

After surgery, the body enters recovery mode. Gentle movement helps stimulate blood circulation so that blood can deliver nutrients and oxygen more effectively throughout the body. This can support faster wound healing while also reducing swelling and pain.

Appropriate movement can also reduce the risk of serious complications such as deep vein thrombosis (DVT), collapsed lung, or respiratory infection, which are more likely to occur when a person remains still for too long.

Importantly, post-operative exercise can help prevent muscle wasting, joint stiffness, and scar-tissue adhesions, all of which may cause long-term movement difficulties if they are not addressed early.

Why Is Correct Post-operative Movement So Important?

In addition to needing to move, it is equally important to move correctly. Incorrect movement may cause a wound to separate, injure a joint, or make muscles work improperly and lead to chronic pain.

For example, getting out of bed without first rolling onto one side may pull on an abdominal surgical wound and cause pain. After knee surgery, placing weight through the wrong area while walking may bruise the wound or contribute to knee deformity.

Physical therapists and occupational therapists therefore teach patients how to change positions correctly, including moving from lying to sitting, walking, using a cane, and sitting or standing, with an emphasis on safety and reducing impact on the surgical wound.

How Important Is Preparing the Body Before Surgery (Pre-hab) ?

When surgery is planned in advance, strengthening the body before entering the operating room can greatly improve the chance of good post-operative recovery. This approach is called “prehabilitation,” or training before surgery.

Benefits ofPhysical TherapyBefore Surgery

• Strengthens muscles needed for movement, such as the thigh, back, and hip muscles.
• Improves the flexibility of joints and muscles, reducing the chance of joint stiffness after surgery.
• Prepares the respiratory system through deep-breathing practice and correct coughing techniques, reducing the risk of a collapsed lung or post-operative infection.
• Reduces anxiety by helping patients understand what will happen and recognise that they can participate in their own recovery.
• Provides practice using walking aids, such as crutches, a walker, or support rails.

Beginning preparation 2–4 weeks before surgery, even for only 15–30 minutes per day, can make a clear difference after the operation.

Why MustPost-operative RehabilitationBegin Early?

Beginning physical therapy or physical rehabilitation within the first 1–3 days after surgery, or as soon as the doctor permits, helps the body enter full recovery mode and effectively reduces complications.

Benefits of Starting Rehabilitation Early

• Reduces the chance of deep vein thrombosis
• Prevents muscle wasting and joint stiffness
• Reduces swelling and pain
• Stimulates the respiratory system to return to normal function
• Helps patients return to daily activities sooner
• Reduces the length of the hospital stay

Even if the first steps involve only moving the toes, practising breathing, or gently lifting a leg while lying down, rehabilitation has already begun.

Good Rehabilitation Must Address the “Body – Movement – Mind”

Post-operative Rehabilitationis not only about moving the body. It also requires attention to correct movement, rest, nutrition, and emotional health.

Begin with basic movements such as getting out of bed, walking around the room, and continuously training important muscles. Activity levels should be increased gradually.

Emotions are an important part of recovery. Anxiety, fear, or discouragement may make a patient unwilling to move or refuse training. Encouragement, family support, and seeing personal progress can greatly restore motivation.

Food and Rest Are Equally Important

Nutrition: Eat protein-rich foods such as meat, eggs, tofu, and beans, and obtain vitamin C and zinc to support wound healing and reduce the chance of infection.

Hydration: The body needs water to remove waste and transport nutrients. Drinking enough water can therefore help reduce swelling and prevent constipation.

Sleep: Aim for at least 7–8 hours of sleep each day so that the body can recover fully, especially at night when the source states that repair-related hormone release is at its highest.

Advice for Patients and Caregivers

1. Start Moving Early, as Permitted by the Doctor Do not remain still in bed for too long.
2. Practise Safe Movements such as rolling onto one side before sitting up and avoiding forceful twisting.
3. Eat Nutritious Food to support the formation of new tissue.
4. Drink Enough Water approximately 6–8 glasses per day.
5. Make the Home Safe by removing clutter, using non-slip mats, and installing handrails.
6. Do Not Ignore Minor Pain or Symptoms If the wound becomes swollen or red, or if fever develops, consult a doctor promptly.
7. Follow the Advice of Doctors and Physical Therapists carefully and consistently.
8. Do Not Be Afraid to Move Fear of pain may lead to greater stiffness.
9. Increase Activity Gradually Do not progress too quickly.
10. Keep Encouraging Yourself Every small step is progress.

Appropriate exercise and movement after surgery are essential parts of recovery that should not be overlooked. Preparing before surgery, starting rehabilitation early, and continuing under proper supervision can reduce complications, help wounds heal faster, support an earlier return to normal life, and most importantly, restore confidence in your own body.

“Good recovery does not mean lying still. It means moving safely, purposefully, and consistently.”
