Therefore, considering that the activity of DPP4 is already completely inhibited when DPP4i is used at its therapeutic dose, any increase in exposure to the drug will not have a further hypoglycemic effect (since the enzyme cannot be inhibited by more than 100%)

A comprehensive initial evaluation should include: Complete medical history: Previous weight loss attempts, family history of obesity, current medications (many cause weight gain), surgical history, and psychiatric screening for eating disorders Physical examination: BMI calculation, waist circumference, blood pressure, assessment for acanthosis nigricans, thyroid palpation, and evaluation for Cushing syndrome signs Laboratory workup: Complete metabolic panel, lipid panel, HbA1c, fasting insulin, thyroid panel (TSH, free T3, free T4), vitamin D, testosterone (in appropriate patients), and liver function tests Body composition analysis: DEXA scan or advanced bioimpedance analysis to establish baseline lean mass, fat mass, visceral fat, and bone density Metabolic rate testing: Indirect calorimetry to measure resting metabolic rate, which informs caloric targets far more accurately than estimation equations Psychosocial assessment: Screening for depression, anxiety, binge eating disorder, emotional eating patterns, and readiness for change Risk Stratification and Treatment Planning Based on the initial assessment, patients should be stratified into treatment tiers that align intervention intensity with clinical need
