Health Risk Analysis

Overview

MediGuide analyzes 11 biometric parameters against medical thresholds to detect potential health risks, identify symptoms, and classify severity levels. The system automatically generates personalized health alerts based on the latest medical data.

Risk Severity Levels

The analysis engine uses four risk severity classifications:

CRITICAL

Life-threatening conditions requiring immediate medical attention

HIGH

Serious conditions requiring urgent medical consultation

MEDIUM

Moderate concerns requiring monitoring and lifestyle changes

LOW

Minor deviations or conditions for awareness

Analysis Algorithm

The health analysis runs automatically when medical data is fetched:

const fetchMedicalData = async () => {
  const userId = localStorage.getItem('userId');
  const response = await fetch(
    `http://localhost:3001/api/medical-info/latest?userId=${userId}`
  );
  const data = await response.json();
  
  if (response.ok) {
    setMedicalData(data);
    analyzeHealth(data); // Automatic analysis
  }
};

Glucose Analysis

Hypoglycemia (Critical)

if (data.glucose < 70) {
  detectedSymptoms.push({
    parameter: 'Glucosa',
    level: 'CRÍTICO - Hipoglucemia',
    value: `${data.glucose} mg/dL`,
    symptoms: [
      'Temblores', 
      'Sudoración', 
      'Palpitaciones', 
      'Mareos', 
      'Confusión'
    ],
    recommendations: [
      'Consumir azúcar o bebida azucarada inmediatamente',
      'Buscar atención médica urgente',
      'Descansar y mantenerse hidratado'
    ],
    risk: 'ALTO'
  });
}

Glucose < 70 mg/dL: Critical hypoglycemia requiring immediate sugar consumption and medical attention.

Prediabetes (Medium Risk)

else if (data.glucose >= 100 && data.glucose <= 125) {
  detectedSymptoms.push({
    parameter: 'Glucosa',
    level: 'PREDIABETES',

      'Consultar endocrinólogo',
      'Monitorear glucosa regularmente'
    ],
    risk: 'MEDIO'
  });
}

Glucose 100-125 mg/dL: Prediabetes range requiring lifestyle modifications.

  detectedSymptoms.push({
    parameter: 'Glucosa',
    level: 'DIABETES - Valores Elevados',

      'Cambios dietéticos severos',
      'Monitoreo diario de glucosa'
    ],
    risk: 'CRÍTICO'
  });
}

25.0-29.9	SOBREPESO (Overweight)	MEDIUM
≥ 30.0	OBESIDAD (Obesity)	HIGH

Analysis Output Structure

Each detected symptom follows this structure:

interface DetectedSymptom {
  parameter: string;           // Biometric parameter name
  level: string;              // Condition severity description
  value: string;              // Actual measured value
  symptoms: string[];         // List of associated symptoms
  recommendations: string[];  // List of recommended actions
  risk: 'CRÍTICO' | 'ALTO' | 'MEDIO' | 'BAJO' | 'BAJO-MEDIO';
}

State Management

const [symptoms, setSymptoms] = useState([]);

const analyzeHealth = (data) => {
  const detectedSymptoms = [];
  
  // Run all analysis checks
  // ... (glucose, oxygen, BP, heart rate, etc.)
  
  setSymptoms(detectedSymptoms);
};

Healthy Status

When no abnormalities are detected:

if (symptoms.length === 0) {
  // Display healthy status with general recommendations
  // - Regular exercise: 150 min/week
  // - Balanced diet
  // - 7-9 hours sleep
  // - Stress management
  // - Annual medical checkup
}

When all parameters are within normal ranges, users receive positive feedback and general wellness recommendations.
