A bariatric surgeon:

• Evaluates patients with obesity and related health risks
• Determines eligibility for weight-loss surgery

Their goal is not only weight loss, but long-term improvement in overall health and quality of life.

A bariatric surgeon, on the other hand, is trained to perform surgical procedures when medical management alone is insufficient or when obesity-related health risks are high.

8. How do I prepare for my first appointment with a bariatric surgeon? 

To prepare for your first visit with a bariatric surgeon:

• Carry previous medical records and test reports
• Note your weight history and past weight-loss attempts
• List current medications and supplements
• Be ready to discuss lifestyle habits and eating patterns
• Write down questions or concerns about surgery

This helps the surgeon assess suitability and plan further evaluation.

9. What should I tell my bariatric surgeon before surgery? 

You should inform your bariatric surgeon about:

• Existing medical conditions such as diabetes or heart disease
• Current medications, including blood thinners
• Past surgeries or complications
• Allergies to medications or anaesthesia
• Smoking, alcohol use, or sleep-related breathing issues

Complete disclosure ensures safe surgical planning and recovery.

10. When do I need to see a bariatric surgeon?

You should consider consulting a bariatric surgeon if:

• Your BMI is 35 or higher, with obesity-related health problems
• You have been unable to lose weight through diet and exercise
• Obesity is affecting your daily activities or quality of life
• You have worsening diabetes, blood pressure, or joint problems due to weight

Early consultation helps determine the most effective and safest weight-loss option.
