Health Graph

Health Graph

The Health Graph is the underlying data model that organizes every piece of a user’s health information—from individual vitals to long-term trends—into a unified, interconnected structure. It’s more than just a database table: it’s a dynamic network of relationships that helps the AI Doctor see how each data point impacts the user’s overall health.

Key Idea: The Health Graph links data in context, allowing OmegaX to deliver personalized and proactive care.

• A heart rate measurement at 5 AM is analyzed alongside sleep quality and medication schedules.

• AI considers multiple factors together, rather than isolated readings, for more accurate insights and recommendations.

1. What is the Health Graph?

Think of it as a map where each “node” represents a specific piece of health data or an event:

• Vitals: Heart rate, blood pressure, glucose levels

• Lifestyle Logs: Exercise sessions, meal photos, mood diaries

• Clinical Data: Lab reports, medication history, diagnoses

• Contextual Clues: Time of day, location, stress indicators

• Contextual Reasoning: A single heart rate value means little if we don’t know whether the user just exercised or took new medication.

• Multi-Dimensional: Health is an interplay of symptoms, environment, and genetic predisposition. A graph structure is ideal for exploring these connections.

• Scalability: We can add new “nodes” (like genetic markers or advanced labs) without disrupting existing relationships.

2. Structure & Relationships

Nodes

• Vital Nodes: Represent key biometric readings.

  • Example: "Blood Pressure Reading (Jan 10, 08:00)"

• Medication Nodes: Track prescribed treatments.

  • Example: "Metformin 500 mg"

• Condition Nodes: Store diagnosed health conditions.

  • Example: "Type 2 Diabetes," "Hypertension"

• Lifestyle Nodes: Capture user activities and behaviors.

  • Example: "Run: 3 km," "Meal: Pasta," "Stress Rating: 7/10"

Edges

• Time-Based Links: Connect events that happen close together.

  • Example: "High HR" → "Anxiety Log"

• Cause-Effect Hypotheses: AI detects potential correlations.

  • Example: "High BP" → "Possibly correlated with poor sleep"

• Condition Relevance: Links chronic conditions to influencing factors.

  • Example: "Hypertension" is affected by "Sodium Intake" or "Medication Non-Adherence"

3. How the AI Doctor Uses the Graph

1. Data Retrieval The AI Doctor queries a user’s Health Graph whenever new data arrives. It looks for connected nodes: recent vitals, open symptoms, relevant diagnoses.

2. Correlation & Insights By analyzing the edges, the AI identifies patterns (e.g., “When user’s stress logs increase, so does their resting heart rate”).

The graph helps highlight these relationships.

1. Proactive Recommendations

• If the AI sees repeated “late-night snacking” linked to elevated morning glucose, it suggests adjusting evening routines.

• If someone logs migraines on days with “high pollen count + short sleep,” the AI might warn them in advance.

4. Example Flow

1

Step 1: New Data Arrives

A user’s wearable logs a spike in HR to 110 bpm at 7 AM.

2

Step 2: Graph Update

The system creates a new Vital Node for “HR = 110 bpm at 7 AM”, linking it to:

• "User Woke Up Late"

• "Skipped Breakfast" (if those events are logged).

3

Step 3: AI Doctor Analysis

The AI detects connections between events:

• "Elevated HR"

• "Poor Sleep"

• "User reported stress last night" These patterns inform further analysis.

4

Step 4: Plan Adjustment

The AI suggests a calming morning walk or a brief mindfulness session, storing it as a new recommendation node.

5. Benefits of a Graph Approach

Benefit	Description
Holistic View	Sees the entire “health story” of each user, not just isolated metrics.
Adaptive	Adding new data types (e.g., genomic markers) is straightforward—just add new node types and relevant edges.
Enhanced AI	Graph-based relationships enable deeper correlation, letting the AI detect multi-factor patterns (stress + insomnia + high BP).
Future-Proof	As health standards evolve (new diagnoses, new wearable metrics), the graph can expand without a massive schema overhaul.

6. Ongoing Enhancements

Temporal Graph Extensions

• Enhanced time-series indexing improves AI's ability to detect subtle trends over time.

• Example: Identifying a slow upward trend in average resting heart rate before it becomes a critical issue.

Clinical Integration

• Automated ingestion of hospital/EHR updates ensures "Condition Nodes" stay in sync with official medical diagnoses.

• Reduces manual data entry and improves real-time medical record accuracy.

Predictive Modeling

• AI-powered forecasting predicts future vitals and symptom likelihood based on existing health patterns.

• Example: The AI detects a pattern of poor sleep and stress spikes, predicting a potential increase in blood pressure.

In Summary

The Health Graph is the connective tissue uniting every fragment of a user’s health story. By mapping data as nodes and relationships, OmegaX can detect patterns, create dynamic insights, and drive meaningful change in daily routines. This holistic view underpins our AI Doctors and ensures each recommendation aligns with the user’s broader health context.
