Study Notes

Defining Severe and Complex Obesity

Obesity is becoming a major health issue in the 21st century
Dieting and lifestyle interventions can lead to 6-8% weight loss in the short term, but most people regain weight due to decreased basal metabolic rate
No pharmacotherapy is currently safe and effective for long-term weight loss

Rationale for Surgery

Bariatric surgery can alter the metabolic rate and lead to long-term weight loss maintenance (15-25% weight loss up to 20 years)
Surgery improves obesity-related diseases and quality of life, and leads to long-term survival benefit

Metabolic Surgery

Metabolic syndrome includes Type 2 diabetes, high blood pressure, dyslipidaemia, and polycystic ovary syndrome
Surgery can improve Type 2 diabetes, which may be additional to weight loss
Improved glycaemic control reduces medication needs, making surgery cost-effective

Eligibility and NICE Guidelines

NICE recommends bariatric surgery for people with severe obesity who have tried non-surgical measures with no adequate weight loss
Eligible patients have a high rate of remission or improvement in Type 2 diabetes
About 80% of eligible patients have no medical or psychological reasons why they would not be fit for surgery

Multidisciplinary Assessment

Every patient should be assessed and managed by a multidisciplinary team of healthcare professionals
Improved outcomes are achieved in high-volume, specialized units

Common Operations and Complications

Operation choice is guided by patient, surgeon, and unit preferences
Complications include DVT/PE, anastomotic leakage, and bleeding
Prophylaxis is usually used for at least 1 week to prevent complications

Follow-up and Biochemical Monitoring

Annual blood tests include full blood count, urea and electrolytes, liver function tests, and more
Additional tests are required for gastric bypass, sleeve gastrectomy, and BPD/DS patients
