Bariatric Surgery & Obesity Treatment

Bariatric Surgery: A Treatment Plan Tailored to Your Health

Living with excess weight can affect your mobility, sleep and many aspects of daily life. You may have tried different approaches to losing weight but found it difficult to maintain the results. For suitable patients, bariatric surgery can support long-term weight management and improve health conditions associated with obesity. The goal is to support your overall health and quality of life.

What Is Bariatric Surgery?

Bariatric surgery is the collective name for operations that modify the stomach and, in some procedures, the small intestine to treat obesity. Alongside reducing the amount of food a person can eat, these procedures can influence hunger, fullness and metabolism.

Treatment is planned individually. Your weight, associated health conditions, eating habits and previous treatments are considered when choosing an appropriate procedure.

Who May Be Eligible?

Eligibility for bariatric surgery involves more than the number on the scales. Assessment includes your body mass index (BMI), obesity-related health conditions, previous weight-loss attempts and surgical risk.

According to current international guidelines:

For people with a BMI of 35 kg/m² or above, bariatric surgery is a recommended treatment option, regardless of whether associated health conditions are present.
For people with a BMI of 30–34.9 kg/m², surgery may be considered, particularly when metabolic disease is present or non-surgical treatment has not produced substantial, lasting improvements.

Meeting these criteria does not automatically mean surgery is suitable for you. The final decision follows an assessment by a specialist and the relevant healthcare team.

Main Surgical Options

Gastric Sleeve — Sleeve Gastrectomy

A large portion of the stomach is removed, leaving a smaller, sleeve-shaped stomach. This helps you feel full after smaller meals and may produce hormonal changes that affect appetite. The procedure is irreversible. Acid reflux may develop or existing reflux may worsen in some patients.

Gastric Bypass

A small stomach pouch is created and the small intestine is rerouted. The procedure affects food intake, absorption and metabolic processes. Regular monitoring for vitamin and mineral deficiencies is necessary after surgery.

Each procedure has different advantages and risks. Reflux, diabetes, previous operations and your long-term health needs are important considerations when selecting a procedure.

Effects on Diabetes and Other Health Conditions

In suitable patients, bariatric surgery can support weight loss while improving the management of type 2 diabetes, high blood pressure and sleep apnoea. Some patients may need fewer medicines, although results vary.

For diabetes in particular, the duration of the condition, current treatment and overall health are important. Surgery does not guarantee a complete or permanent resolution of diabetes. Any medication changes must be made by the doctor responsible for your care.

What Is Assessed Before Surgery?

Your medical conditions, medications, previous operations and weight-loss history are reviewed during the assessment. Alongside consultations with the surgeon and anaesthetist, nutritional assessment and psychological support may be arranged where appropriate. Tests and additional specialist consultations are determined according to your health needs.

These appointments also give you an opportunity to discuss your expectations and ask questions about life after surgery.

Understanding the Risks

Possible complications of bariatric surgery include bleeding, infection, leakage from staple lines or surgical connections, and blood clots. Rarely, complications can be life-threatening. Longer-term problems may include nutritional deficiencies, anaemia, gallstones or the need for further procedures.

Risks vary according to the procedure and your health. Before deciding on surgery, discuss the expected benefits, possible complications and alternative treatments in detail with your doctor.

What Changes After Surgery?

After surgery, you will follow a staged eating plan provided by your healthcare team. Adequate fluid and protein intake, prescribed vitamin and mineral supplements, appropriate physical activity and regular blood tests are all part of ongoing care.

Lifelong follow-up is essential. Weight regain is possible; if it occurs, the causes should be assessed and your treatment plan reviewed. The length of your hospital stay, return to work and fitness to travel depend on the procedure and your recovery.
