What is robotic bariatric surgery?

Robotic bariatric surgery is a form of minimally invasive weight-loss surgery where a surgeon uses camera-guided robotic instruments inserted through small cuts in the belly. Many common procedures, such as gastric sleeve and gastric bypass, can often be performed this way. Whether it is the right approach for you is something your surgeon decides based on your individual health.

Who may be a candidate for weight-loss surgery?

For many people, a BMI of 35 or higher is a common starting point for a discussion about bariatric surgery. For some people with a BMI between 30 and 35 who have type 2 diabetes that is hard to control, surgery may also be considered. A full medical evaluation by your health care team helps determine whether surgery is appropriate for you.

What are the main risks of bariatric surgery?

Risks can include bleeding, infection, blood clots, reactions to anesthesia, leaking from staple lines inside the stomach, nutritional deficiencies, and stomach problems such as heartburn or ulcers. If after surgery you experience severe pain, high fever, chest pain, or difficulty breathing, call 911 or go to an emergency room right away.

What to Ask a Surgeon Before Robotic Weight-Loss Surgery

2026-11-06 · By Robotic Bariatric Surgery Editorial · General information, not medical advice

This guide gives you a practical list of questions to bring to your bariatric surgery consultation, covering robotic surgery approaches, risks, eligibility, and follow-up care.

Why Your Questions Matter

Weight-loss surgery involves making permanent changes to your digestive system. For many people, it is one of the most significant health decisions they will ever make. Asking your surgeon detailed questions before you agree to anything is not just allowed, it is strongly encouraged. Good surgeons welcome an informed patient. This article gives you a solid starting list.

Questions About How the Surgery Is Done

In the United States, surgeons most often perform three types of weight-loss operations: gastric sleeve, gastric bypass, and adjustable gastric band. Many of these procedures can be performed using robotic surgery systems, which guide small instruments and a camera through tiny cuts in the belly. This is a form of minimally invasive surgery. Whether robotic surgery is the right approach for you is something your surgeon decides based on your individual health and circumstances.

Ask your surgeon:

Which procedure do you recommend for me, and why? The right operation depends on a number of factors, including your health history and any other medical conditions you have.
Will you use robotic surgery, standard laparoscopy, or open surgery? Understanding the approach helps you know what to expect before, during, and after the procedure.
Is this surgery reversible? Some procedures, like gastric sleeve, cannot be reversed because part of the stomach is permanently removed. Ask for a clear explanation before you commit.
How long does the operation typically take? Sleeve gastrectomy, for example, often takes around 60 to 90 minutes in many cases.

Questions About Risks

All surgery carries risk. Weight-loss surgery is no different. Knowing the possible risks ahead of time helps you make a fully informed decision and helps you recognize when to seek help after the procedure.

Common risks associated with bariatric surgery can include:

Bleeding, blood clots, or infection
Reactions to anesthesia
Leaking from the staple lines where parts of the stomach are joined
Stomach problems such as gastritis, heartburn, or ulcers
Poor nutrition and vitamin deficiencies
Gallbladder problems

Ask your surgeon these questions about risk:

What are the most common complications with this procedure?
What warning signs should I watch for after I go home? Know that severe pain, high fever, difficulty breathing, or signs of a blood clot are reasons to call 911 or go to an emergency room right away.
Will I need to take vitamins or supplements long term?

Questions About Eligibility

Not everyone is a candidate for weight-loss surgery. For many people, a body mass index, or BMI, of 35 or higher is a common starting point for a conversation with a surgeon. For some people with a BMI between 30 and 35 who have type 2 diabetes that is difficult to control, surgery may also be considered as an option. Your health care team will determine whether surgery is appropriate for you, usually after a thorough medical evaluation.

Ask your surgeon:

Am I a good candidate based on my health history?
Do I need any tests or evaluations before surgery?
Are there conditions that could make surgery too risky for me right now?

Questions About the Surgeon and the Facility

It is completely reasonable to ask about your surgeon's training and experience with the specific procedure you are considering, including their experience with robotic surgery systems. You are also allowed to ask about the facility where the surgery would take place and what support services are available.

If you are in California, you can verify that your surgeon holds a valid state medical license at the Medical Board of California website: mbc.ca.gov. Type that address into your browser and search by name.

Additional questions to consider:

How many times have you performed this specific procedure?
Who else will be part of my care team? Dietitians, mental health professionals, and other specialists are often involved in a bariatric care program.
What follow-up appointments will I need, and for how long?
What do I do if I have a complication after leaving the hospital?

What to Keep in Mind

Weight-loss surgery is not a quick fix. Long-term results for many people depend on lasting changes to diet, physical activity, and consistent follow-up care. Robotic surgery techniques allow surgeons to work with great precision through very small incisions, but no outcome is promised with any surgical approach. Use the questions in this article as a starting point, and add any personal questions that come to mind before your appointment. The more you understand going in, the better prepared you will be.
