Dr. Hannah Whitfield

Health & Wellness Writer

Medical Reviewer

Hannah reviews and writes Calcavio's health tools - BMI, calorie, hydration, BMR, and pregnancy-timeline calculators for medical accuracy. Her role is to keep the content evidence-based, conservative, and clearly framed as education, never diagnosis. Every health result is a starting estimate, and she makes sure each tool tells readers plainly when to consult a qualified healthcare professional.
