Surgery is an effective way to lose weight when dieting and exercise is no longer working. This article covers key considerations you will need to think about as you decide if surgery is right for you.
Weight loss surgery is not a ‘quick fix’ cure for obesity. Achieving your goal weight is a lifelong journey. We call it a journey because it's a lifelong process of making small commitments towards positive change and better health and happiness. Your ability to lose weight successfully will depend on how well you follow your aftercare plan and adapt to eating much smaller portions.
Why choose weight loss surgery?
If private healthcare is an option then the costs of the procedures are expensive and will involve cost planning. You will need to plan ahead and weigh up the financial costs against the benefits of having surgery. In making your decision, it can help to consider the financial and non-financial burden of living with obesity.
Before deciding on the right procedure you need that you know the risks involved (contraindications).
Weight loss surgery is not advised when it may be harmful or fatal. Certain medical conditions and symptoms can mean that surgery can put your life at risk. It is crucial to discuss your medical history with your surgeon before making a decision.
Some contraindications for weight loss surgery include:
- Alcohol abuse or drug dependence
- Barrett's esophagus or esophagitis
- Cardiopulmonary (heart and lung) disease that makes the surgery risky
- Uncontrolled psychiatric disorders such as depression or schizophrenia
In the UK, weight loss surgery is available on the NHS for people who meet a criteria. However, the NHS criteria for the surgery can vary across England. You will need to check with your GP if you think surgery on the NHS pathway could be an option for you.
If you chose to go private you will need to carefully research the private clinics offering weight loss surgery. You might want to compare different surgeries by their patient feedback and the costs of their procedures.
Some people seek weight loss surgery outside of the UK where the cost of private surgery can be lower than in the UK. If you are considering surgery abroad then it is important to weigh up the potential savings against the potential risks. It is advised to carefully research each country against international healthcare standards and factor in any complications that can occur in delivering aftercare.
