Integrating weight management into post-VTE follow-up.

Timing	Opportunity	Rationale	Potential interventions
Initial VTE diagnosis	Screen for elevated BMI using percent-of-BMI95a	Early identification of overweight/obesity may signal future cardiometabolic risk	Routine BMI assessment; flag elevated percent-of-BMI95 for follow-up
Hospitalization or early outpatient visits	Educate families on physical activity and weight changes after VTE	Misconceptions about activity restrictions post-VTE may lead to reduced mobility and weight gain	Provide exercise guidance from thrombosis team; involve physical therapy
3–6 mo follow-up	Monitor BMI trajectory after VTE	Study shows average increase in BMI percent within 6 mo; critical window for intervention	Refer to dietitian or weight management services; reinforce healthy lifestyle counseling
Long-term follow-up (12+ mo)	Address persistent or worsening weight gain	Sustained obesity may compound long-term vascular and cardiometabolic risks	Consider integrating pediatric obesity specialists
Research and quality improvement	Embed weight management into VTE outcome studies	BMI change is an underrecognized but potentially modifiable outcome after VTE	Include BMI as a longitudinal outcome in VTE registries

BMI, body mass index; VTE, venous thromboembolism.

^aBMI₉₅ is a calculated measure adjusting for age- and sex-specific growth ([BMI/BMI at the 95th percentile for age and sex] × 100).
