fasting guidelines

Fasting guidelines vary depending on the purpose (medical tests, surgeries, religious observances). Generally, they recommend abstaining from food and drink for a specified period, often 8-12 hours, before procedures to ensure accurate results or safety. Water intake may be allowed, but consult your healthcare provider for specific instructions. It’s important to follow your provider’s guidance carefully, especially if you have certain health conditions like diabetes, as fasting can affect blood sugar levels. Always clarify how long to fast and any restrictions needed to ensure it's safe and effective for your situation.
