Gastric Sleeve Surgery Eligibility Criteria

Several factors are considered together when assessing suitability for gastric sleeve surgery. The table below outlines the key areas reviewed during a consultation.

Eligibility Factor

What Is Considered

BMI

Generally, a BMI over 35, or over 30 with related health conditions

Obesity-Related Conditions

Type 2 diabetes, sleep apnoea, high blood pressure, joint pain

Reflux and Heartburn

Severity and frequency of symptoms, as this may affect choice of surgery 

Previous Weight Loss Attempts

History of diet, exercise or medical weight loss efforts

Mental Readiness

Emotional stability and understanding of the lifestyle changes involved

Medical Safety

Overall health, surgical risk and ability to safely undergo anaesthesia

Long-Term Commitment

Willingness to follow post-surgery dietary and lifestyle guidance

BMI Requirements and Health Conditions

BMI is a useful starting point for assessing gastric sleeve surgery eligibility, but it is always considered alongside your broader health profile. Many patients are also living with one or more obesity-related conditions, which can support the case for surgery as a medical treatment rather than a cosmetic choice.

  • Type 2 Diabetes:  A history of type 2 diabetes, your current medications and how well your blood sugar is controlled may all be reviewed as part of your assessment.
  • Sleep Apnoea: Sleep apnoea is commonly linked with obesity, and a confirmed diagnosis may support the need for weight loss treatment.
  • High Blood Pressure: Blood pressure readings and overall heart health risk are often part of the broader medical assessment.
  • Joint Pain and Mobility Issues: Excess weight places ongoing strain on the knees, hips, back and joints, which can affect daily movement and quality of life.
  • Reflux and Heartburn: Reflux is an important consideration, as gastric sleeve surgery may not be suitable for every patient with significant or ongoing reflux symptoms.

A Thorough Assessment Focused on Long-Term Success

Mr. Niruben Rajasagaram does not recommend gastric sleeve surgery based on weight alone. The assessment looks at BMI, health history, reflux, diabetes, previous weight loss attempts, mental readiness and lifestyle factors as a whole.

You will be given a clear explanation of what gastric sleeve surgery involves, what to expect during recovery, and what ongoing care looks like. Where helpful, additional support may be arranged through our dietitian, Ms Stefania Basso, and our habits and transformation coach, Dr Monica Devanand.

Every recommendation is guided by safety, suitability and your long-term care needs.

When Gastric Sleeve Surgery May Not Be Recommended

Providing the right treatment at the right time is a key part of our approach. Mr. Niruben Rajasagaram considers a range of medical and lifestyle factors to determine whether gastric sleeve surgery is appropriate for each patient. 

Factors that may affect suitability include:

  • Untreated mental health conditions

  • Substance dependence

  • Poor nutritional status

  • An inability to follow post-surgery care requirements

This does not necessarily mean surgery is no longer an option. In many cases, additional preparation, testing, or support can help ensure surgery is performed safely and at the right time.

Not Sure Which Surgery Is Right for You?

Eligibility is best confirmed through a proper medical assessment rather than guesswork. If you are unsure whether gastric sleeve surgery could be right for you, Mr. Niruben Rajasagaram can review your health history, BMI and goals during a personal consultation and talk you through your options.
