You may have to follow certain instructions two days before your fluoroscopy.
For instance, if your doctor wants to see the digestive tract, you may need to follow a liquid diet. Your doctor will give you the full details of what you should and shouldn't eat or drink.
But if your fluoroscopy is to study a joint, you'll need to do little to prepare.
You should let your doctor know if you are or may be pregnant. The radiation involved with fluoroscopy can be harmful to a fetus.
You should also tell your doctor about any allergies, in case you could react to a contrast agent.
Let your doctor know what medicines you take. They may ask you to briefly stop taking certain drugs that could affect the test.
If you have an insulin pump or glucose monitor, the readings can be affected by the radiation. Notify the tech before starting the exam if you have one. It is recommended that you remove the device if possible, if you cannot, monitor your readings closely to ensure they are accurate or replace with a new device after exam.
