NutriFlow – Clinical Diet & Enteral Feeding Calculator

NutriFlow is a frontend web application that automates clinical nutrition calculations including Ideal Body Weight (IBW), Resting Energy Expenditure (REE), and enteral feeding prescriptions using validated clinical formulas.

The project is designed to simulate real hospital nutrition workflows with a strong focus on accuracy, usability, and clean UI logic.

🚀 Key Features

• IBW Calculation Hamwi, Devine, and Robinson methods

• REE Calculation Harris-Benedict, WHO, Owen, Mifflin-St Jeor, and Liu equations

• Protein Requirement Estimation Adjustable based on clinical goals

• Enteral Product Database 12 products with detailed nutritional specifications

• Smart Filtering Filter by sodium content, caloric density, and protein levels

• Dilution & Volume Calculator Half, standard, and double concentration options

• Prescription Output Nursing-ready diet prescription summary

🧠 Why This Project

Clinical nutrition calculations are often done manually or using spreadsheets, which is time-consuming and error-prone. NutriFlow demonstrates how frontend logic and structured JavaScript can be used to automate healthcare workflows reliably.

This project focuses on:

• Translating domain logic into code
• Clean separation of UI, data, and calculations
• Building production-style frontend applications without frameworks

---

🛠️ Tech Stack

• HTML5 – Semantic structure
• CSS3 – Responsive layout using Flexbox & Grid
• JavaScript (Vanilla) – Modular logic and state handling

No backend or external libraries required.
