How long do you fast before a barium enema?
Doctors usually give the patient written instructions. Perhaps they are inside your "prep kit."
If not, call your doctor and ask because preparations vary.
According to the National Institute of Health,
"Generally, a clear liquid diet is given 1 to 3 days prior to the procedure."
Don’t risk messing up your test! Call the doctor to confirm which preparation is right for you.
