Obesity with prediabetes progressing to T2DM — CCE clinical encounter
CCE-style clinical encounter: a 48-year-old man with BMI 33, prediabetes and multiple failed diet attempts asks about 'the injection'. The candidate must raise obesity as a chronic disease without stigma, apply DPP lifestyle evidence, discuss GLP-1 pharmacotherapy honestly including supply constraints, explain weight regain biology, and screen for complications.

Prompt
A 48-year-old accountant attends after his brother was diagnosed with T2DM. His BMI is 33 (waist 108 cm). HbA1c is 6.0% (prediabetes). He has tried Weight Watchers twice, lost 8 kg each time then regained more. He wants 'Ozempic for the weight'. He has no known T2DM. BP 138/86. He mentions he snores loudly and wakes unrefreshed.
Objectives
- Raise obesity using person-first language and permission-based approach. [7]
- Apply DPP evidence to structure a lifestyle intervention plan. [1]
- Discuss GLP-1 pharmacotherapy with honest efficacy data and supply realities. [4] [5]
- Explain weight regain biology to reframe previous diet failures. [9]
- Screen for complications: OSA symptoms, MASLD enzymes, depression. [3]
