What To Expect Before Stress Testing

Stress testing is done in a doctor’s office or at a medical center or hospital. You should wear shoes and clothes in which you can exercise comfortably. Sometimes you’re given a gown to wear during the test.

Your doctor might ask you to fast (not eat or drink anything but water) for a short time before the test. If you're diabetic, ask your doctor whether you need to adjust your medicines on the day of the test.

For some stress tests, you can't drink coffee or other caffeinated drinks for a day before the test. Certain over-the-counter or prescription medicines also may interfere with some stress tests. Ask your doctor whether you need to avoid certain drinks or food or change how you take your medicine before the test.

If you use an inhaler for asthma or other breathing problems, bring it to the test. Make sure you let the doctor know that you use it.
