This guide is general education, not a diagnosis or an individual treatment plan. Urgent, severe or worsening symptoms belong with the local emergency service or a qualified clinician.
What this guide covers
"What to do before and after X": fasting before a blood test (the top health query in et/fi/ru that the apex cannot answer), colonoscopy prep diet day by day, gastroscopy, surgery pre-op nutrition and post-op protein, tooth extraction, vaccination day, MRI, glucose tolerance test, ultrasound.
How to use it
Start with the description that most closely matches your question about Before and after a medical procedure: eating and fasting. Use the evidence section to understand what is known, then use the boundary section to decide when self-education should stop and clinical care should begin.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.
