Obesity is often associated with abnormal cardio respiratory function, metabolic function and haemostasis, which may predispose a patient to complications during or post-surgery.

Obesity is often associated with abnormal cardiorespiratory function, metabolic function and haemostasis, which may predispose a patient to complications during or post-surgery.

As obesity becomes more prevalent, it becomes more common among patients considering orthopaedic surgery. Obesity has been identified as a top risk factor for the initiation and progression of osteoarthritis in load-bearing joints, primarily the knee, but also the hip and ankle.

Obesity can make surgery more challenging. If you or a loved one are overweight or obese and planning to have surgery, you should be aware that excess weight can put you at risk for certain side effects and complications. These can result from the surgery itself, or from the anaesthesia you may need during your surgery.

Maintaining a healthy lifestyle can have a significant impact on orthopaedic surgery outcomes. Here are some ways a healthy lifestyle can affect orthopaedic surgery outcomes, with reference to orthopaedic surgery:

Reduced risk of complications: Living a healthy lifestyle, including regular exercise and a balanced diet, can help reduce the risk of complications during and after surgery. For example, being in good cardiovascular health can help reduce the risk of blood clots during surgery.

Faster recovery: A healthy lifestyle can also help speed up the recovery process after surgery. Exercise, for example, can help improve range of motion and reduce stiffness, while proper nutrition can provide the body with the nutrients it needs to heal.

Better overall health: Living a healthy lifestyle can also improve overall health, which can in turn improve orthopaedic surgery outcomes. For example, maintaining a healthy weight can reduce the strain on joints, which can reduce the risk of future orthopaedic problems.

In South Africa, where orthopaedic surgery is widely available, a healthy lifestyle can be especially important for patients who may be at a higher risk of complications due to factors such as age, obesity, or other health conditions. By taking steps to improve their overall health and wellness, patients can improve their chances of a successful surgery and a speedy recovery.
