In certain situations, you may be able to drink clear liquids up to a few hours before a procedure.
It’s important to check with your healthcare professional to determine whether any foods or beverages are allowed during your fasting period.
The most common types of fasting are intermittent fasting, religious fasting (such as for the month of Ramadan), and medical fasting, each of which has varying levels of strictness.
