What Tests Are Done Before Bariatric Surgery?

Many people considering bariatric surgery are curious about what tests are done before the procedure. Choosing weight loss surgery represents a significant investment in your health, requiring proper planning and care to ensure a successful outcome.

While there are different types of bariatric surgeries, all of them typically require a series of tests to help determine if you’re an ideal candidate for the procedure.

Knowing what tests are done before bariatric surgery can help you prepare for the process, as well as understand why these tests are important. This article will explain exactly what tests you can expect prior to having weight loss surgery.

However, depending on your situation, bariatric surgery may not be the best option for you at this point. It’s important to reduce complications and risks. With proper testing, your surgeon can see various indicators that you are ready to undergo the surgery.

So what tests are done before gastric bypass surgery? Let’s explore the different examinations you may need before weight loss surgery.

The Importance Of Tests Prior to Bariatric Surgery

Testing is crucial for the following reasons:

  • Inform your surgeon on the best method to use
  • Help you understand how to recover quickly and safely post-op
  • Give you detailed information on how the weight loss surgery will go
  • Gain medical clearance for bariatric surgery

What Pre-Surgery Assessments Are Done Before Bariatric Surgery?

There are different preoperative tests that the surgeon may request that you do. This screening is to make sure that you are safe during and after the operation. Examples of medical tests you’ll need before bariatric surgery are:


An EKG test is akin to a stress test and cardio echo test. It helps determine how strong your heart valves are functioning.

Lab Tests Before Bariatric Surgery

A common type of lab test is to have a thyroid test before your bariatric weight loss procedure. Additionally, the surgeon will analyze all of your blood that includes vitamins, iron, and hemoglobin levels.

If there are vitamin deficiencies, they can suggest you supplement specific vitamins before having the procedure.

Additional Testing Information

Your weight loss surgeon can also request the following exams:

  • EGD before bariatric surgery
  • Blood tests before bariatric surgery

Testing is the first step to your weight loss surgery. While testing may be somewhat time-consuming, it’s very necessary. It’s much better to know exactly how your body might hold up during and after the operation.

This way the surgeon can select the best method to help you lose weight. They can also instruct you with the best instructions to follow post-op to stay healthy, keep the weight off, and slim down even further.
