## Overview

Diabetes Care Home is an open-source application that combines machine learning with interactive health tools to support diabetes awareness and management. The platform enables users to:

- Assess their diabetes risk using a trained machine learning model
- Explore and visualize health data patterns through interactive charts
- Get instant answers to health queries via an AI-powered chatbot
- Access evidence-based lifestyle recommendations
- Connect with a community through a discussion forum

### Why This Project?

Diabetes affects millions worldwide, and early detection is crucial for effective management. This platform aims to make diabetes risk assessment accessible to everyone while providing educational resources and community support.

> **Medical Disclaimer:** This application is intended for educational and informational purposes only. It does not provide medical advice, diagnosis, or treatment recommendations. Always consult a qualified healthcare professional for medical concerns.

## Features

### 1. Diabetes Risk Prediction

The core feature uses a machine learning model trained on the Pima Indians Diabetes Dataset. Users input eight health parameters:

| Parameter | Description | Unit |
|-----------|-------------|------|
| Pregnancies | Number of pregnancies | Count |
| Glucose | Plasma glucose concentration (2 hours after glucose tolerance test) | mg/dL |
| Blood Pressure | Diastolic blood pressure | mm Hg |
| Skin Thickness | Triceps skin fold thickness | mm |
| Insulin | 2-Hour serum insulin | mu U/ml |
| BMI | Body Mass Index | kg/m² |
| Diabetes Pedigree Function | Genetic predisposition score | Score |
| Age | Age of the individual | Years |

The model processes these inputs through a StandardScaler for normalization and returns a binary prediction (Diabetic / Not Diabetic).

### Note on Prediction Inputs

The diabetes prediction model is trained on the Pima Indians Diabetes Dataset.
Due to limitations of the dataset, gender and individual height/weight values are not included as input features.
BMI is used as a combined indicator of height and weight.

### 2. Data Exploration Dashboard

Interactive visualization tools for understanding diabetes-related health patterns:

- **Correlation Heatmap** — Displays relationships between all health variables using Seaborn
- **Glucose Distribution** — Interactive histogram showing glucose level patterns across the dataset
- **BMI Distribution** — Visual analysis of Body Mass Index distribution

All charts are rendered using Plotly for interactivity and Matplotlib/Seaborn for statistical visualizations.

### 3. AI-Powered Chatbot

An intelligent assistant powered by Google Gemini API that can:

- Answer diabetes-related health questions
- Provide general information about symptoms, causes, and management
- Offer guidance on lifestyle modifications
- Respond in a conversational, user-friendly manner

### 4. Lifestyle Recommendations

Curated, evidence-based guidance covering:

- Dietary recommendations for blood sugar management
- Exercise and physical activity guidelines
- Stress management techniques
- Sleep hygiene practices
- Regular monitoring schedules

### 5. Community Forum

A simple discussion platform where users can:

- Share their experiences and stories
- Ask questions to the community
- Provide peer support
- View posts in reverse chronological order

## Getting Started

### Prerequisites

Before you begin, ensure you have the following installed:

- **Python 3.8 or higher**
  ```bash
  # Check Python version
  python --version

```

* **pip package manager**
```bash
# Check pip version
pip --version

```

* **Git**
```bash
# Check Git version
git --version

```

* **Docker Desktop** (Optional, for containerized setup)
* Required if you plan to run the application using Docker.

* **Google Gemini API Key** — Required for the chatbot feature
* Visit [Google AI Studio](https://makersuite.google.com/app/apikey)
* Sign in with your Google account
* Click "Create API Key"
* Copy and save the key securely

### Installation (Manual Method)

#### Step 1: Clone the Repository

```bash
# Clone via HTTPS
git clone [https://github.com/your-username/diabetes-care-home.git](https://github.com/your-username/diabetes-care-home.git)

# Or clone via SSH
git clone git@github.com:your-username/diabetes-care-home.git

# Navigate to project directory
cd diabetes-care-home

```

#### Step 2: Create Virtual Environment

Creating a virtual environment isolates project dependencies from your system Python.

**Windows (Command Prompt):**

```cmd
python -m venv venv
venv\Scripts\activate

```

**Windows (PowerShell):**

```powershell
python -m venv venv
.\venv\Scripts\Activate.ps1

```

**macOS / Linux:**

```bash
python3 -m venv venv
source venv/bin/activate

```

You should see `(venv)` prefix in your terminal indicating the virtual environment is active.

#### Step 3: Install Dependencies

```bash
# Upgrade pip to latest version
pip install --upgrade pip

# Install all required packages
pip install -r requirements.txt

```

This installs the following packages:

* flask, flask-cors
* numpy, pandas
* matplotlib, seaborn, plotly
* scikit-learn
* python-dotenv
* google-generativeai
* gunicorn

#### Step 4: Configure Environment Variables

Create a `.env` file in the project root directory:

**Windows (Command Prompt):**

```cmd
echo GEMINI_API_KEY=your_api_key_here > .env

```

**Windows (PowerShell):**

```powershell
"GEMINI_API_KEY=your_api_key_here" | Out-File -FilePath .env -Encoding utf8

```

**macOS / Linux:**

```bash
echo "GEMINI_API_KEY=your_api_key_here" > .env

```

Or manually create the file with the following content:

```env
GEMINI_API_KEY=your_actual_gemini_api_key

```

> **Security Note:** Never commit your `.env` file to version control. It should already be listed in `.gitignore`.

#### Step 5: Verify Model Files

Ensure the following pre-trained model files exist in the project root:

* `diabetes_model.pkl` — Trained classification model
* `scaler.pkl` — Feature scaler for input normalization
* `diabetes.csv` — Dataset for visualization features

If missing, you can retrain the model using the provided Jupyter notebook:

```bash
# Install Jupyter if not available
pip install jupyter

# Launch Jupyter and run train.ipynb
jupyter notebook train.ipynb

```

#### Step 6: Run the Application

**Development Mode:**

```bash
python app.py

```

**Production Mode (using Gunicorn):**

```bash
gunicorn app:app --bind 0.0.0.0:5000

```

#### Step 7: Access the Application

Open your web browser and navigate to:

```
http://localhost:5000

```

You should see the Diabetes Care Home landing page.

### 🐳 Installation (Docker Method)

If you prefer to run the application in a consistent containerized environment, follow these steps instead of the manual installation.

1. **Prerequisite:** Ensure **Docker Desktop** is installed and running on your machine.
2. **Configure Env:** Create the `.env` file as described in **Step 4** above.
3. **Run:** Open your terminal in the project root and run:
```bash
docker-compose up --build

```

4. **Access:** Open your browser to `http://localhost:5000`.

To stop the container, press `Ctrl+C` in the terminal.
