Tests and visits before surgery
Your surgeon will want to make sure you are ready for your surgery. To do this, you will have some checkups and tests before surgery.
Many different people on your surgery team may ask you the same questions before your surgery. This is because your team needs to gather as much information as they can to give you the best surgery results. Try to be patient if you are asked the same questions more than once.
Pre-op Checkup
Pre-op is the time before your surgery. It means "before operation." During this time, you will meet with one of your health care providers. This may be your surgeon or primary care provider:
- This checkup usually needs to be done within the month before surgery. This gives your providers time to treat any medical problems you may have before your surgery.
- During this visit, you will be asked about your health over the years. This is called "taking your medical history." Your provider will also do a physical exam.
- If you see your primary care provider for your pre-op checkup, make sure your hospital or surgeon gets the reports from this visit.
Some hospitals also ask you to have a phone conversation or meet with an anesthesia pre-op nurse before surgery to discuss your health.
You may also see your anesthesia provider the week before surgery. This provider will give you medicine that will make you sleep and not feel pain during surgery.
Visits With Other Doctors
Your surgeon will want to make sure that other health conditions you may have will not cause problems during your surgery. So you may need to visit:
- A heart doctor (cardiologist), if you have a history of heart problems or if you smoke heavily, have high blood pressure or diabetes, or are out of shape and cannot walk up a flight of stairs.
- A diabetes doctor (endocrinologist), if you have diabetes or if your blood sugar test in your pre-op visit was high.
