- RESPONSIBILITIES
Patient Portal
- Interactive dashboards visualizing body composition changes (weight, fat mass, muscle mass, visceral fat, hydration) correlated with medication timing and dosage
- Subscription management system for GLP-1 medications with dosage tracking and shipment coordination
- Medication effectiveness visualization showing expected vs. actual body composition changes
- Personalized progress timelines that adapt to individual medication response patterns
- Self-service tools for prescription renewals, dosage adjustments, and provider communication
Data Visualization & Insights:
- Real-time body composition graphs that segment changes by tissue type (skeletal muscle, visceral fat, subcutaneous fat, water content)
- Medication dosage calculators with weight-adjusted effectiveness modeling
- Interactive comparison views showing body composition quality metrics
- Expected change projections based on medication type, dosage, and individual physiology
Provider Integration:
- Secure messaging and consultation request interfaces
- Shared dashboards allowing patients and providers to review the same data
- Treatment plan tracking with milestone-based progression
- Clinical recommendation displays generated by our AI assistant (Pro.f)
