Health Checkup Fasting Countdown Timer
Just enter your appointment time — we back-calculate when to stop eating and drinking, with an ICS reminder you can add to your calendar.
⚠️ Health reference only
This tool mechanically back-calculates general fasting rules (general checkup 8h / endoscopy 12h, water until 2h before). Always confirm the exact fasting time and water rules with your booked checkup clinic. Requirements vary by endoscopy inclusion, sedation, and medications (diabetes, blood pressure, etc.).
