Clinical Scorecard: Changes in 29 Anthropometric, Nutritional, and Cardiometabolic Factors in Severely Obese Adolescents Two Years Following Sleeve Gastrectomy

At a Glance

Key Highlights

• LSG leads to durable weight loss and improvement in multiple cardiometabolic parameters in severely obese adolescents at 2 years postoperatively.
• Nutritional deficiencies are common preoperatively due to poor diet and may worsen post-LSG without appropriate recognition and supplementation.
• Comprehensive assessment of 29 anthropometric, nutritional, and cardiometabolic factors provides detailed insight into postoperative changes and de novo deficiencies.

Guideline-Based Recommendations

Diagnosis

• Define dyslipidemia as TC ≥ 5.17 mmol/L, LDL ≥ 3.36 mmol/L, HDL ≤ 1 mmol/L, TG ≥ 1.4 mmol/L.
• Define type 2 diabetes as FBG ≥ 7 mmol/L or HbA1c ≥ 6.5%; prediabetes as HbA1c 5.7–6.4% or FBG 5.6–6.9 mmol/L.
• Use standard biochemical assays and anthropometric measurements (weight, BMI, excess weight, EWL%) pre- and postoperatively.

Management

• Treat preoperative vitamin and mineral deficiencies prior to surgery.
• Implement postoperative nutritional supplementation and monitor adherence to prevent or address deficiencies.
• Restrict diet to liquids for first 3 postoperative weeks, progressing as tolerated.

Monitoring & Follow-up

• Regularly monitor anthropometric parameters, nutritional markers (hemoglobin, iron, ferritin, vitamins, minerals), and cardiometabolic markers (lipids, liver enzymes, glucose, HbA1c, PTH, uric acid) at baseline and follow-up.
• Assess for resolution of comorbidities using defined biochemical thresholds without medication.
• Identify and manage de novo nutritional deficiencies emerging postoperatively.

Risks

• Risk of nutritional deficiencies due to restricted intake, food intolerance, and insufficient supplementation post-LSG.
• Potential worsening of preexisting nutritional deficiencies if unrecognized.
• Cardiometabolic risks associated with persistent or unresolved comorbidities if weight loss or metabolic improvement is inadequate.

Patient & Prescribing Data

Severely obese adolescents aged 13–17 years undergoing primary or revisional LSG

Preoperative correction of nutritional deficiencies and postoperative supplementation are critical to optimize outcomes; LSG effectively reduces weight and improves cardiometabolic risk factors over 2 years.

Clinical Best Practices

• Conduct comprehensive preoperative assessment including anthropometric, nutritional, and cardiometabolic parameters.
• Correct nutritional deficiencies before surgery to minimize postoperative complications.
• Implement standardized surgical technique with intraoperative leak testing.
• Provide structured postoperative dietary progression and supplementation protocols.
• Perform long-term follow-up to monitor weight loss, comorbidity resolution, and nutritional status.
• Use defined biochemical criteria to evaluate resolution of dyslipidemia, prediabetes, and type 2 diabetes.
