How pre-op physicals detect hidden BP problems

Going in for surgery can be a big deal, and doctors want to make sure everything goes as smoothly as possible. That’s why they often ask patients to have a pre-op physical before the big day. One of the main reasons for this check-up is to catch hidden health problems—especially high blood pressure—that could cause trouble during or after surgery.

High blood pressure, also called hypertension, doesn’t always show obvious symptoms. Many people walk around with it and don’t even know they have it. But when you’re about to have surgery, having high blood pressure can increase your risk of complications like bleeding more than usual or having heart problems under anesthesia.

During a pre-op physical, your doctor will check your vital signs: things like your heart rate and especially your blood pressure. If your numbers are higher than normal, that’s a red flag that you might have hidden hypertension. The doctor might also ask about any family history of heart disease or if you take medications for other conditions.

Sometimes, extra tests are done too—like an electrocardiogram (EKG) to look at how well your heart is working or blood tests to check for other issues that could affect how safe surgery is for you.

If high blood pressure is found during the pre-op exam, doctors can take steps before surgery starts. They might adjust medications or recommend lifestyle changes like eating healthier foods or getting more exercise. Sometimes they even delay the procedure until things are under better control.

Catching these hidden problems early means doctors can plan ahead and make sure everything goes as safely as possible when it comes time for surgery. That way, patients get the best care tailored just for them—and everyone involved feels more confident about what happens next in the operating room.
