Dr. Garth Davis believes that weight loss is a journey, not a destination. Sometimes, despite your best efforts, your initial surgery might need a "tune-up" or a change in direction. Whether you are experiencing weight regain or struggling with complications like severe acid reflux, Dr. Garth Davis offers compassionate, expert care to help you get back on track.
Revisional surgery is significantly more complex than initial weight loss procedures, requiring a surgeon with exceptional technical skill and deep experience. Dr. Garth Davis is a board-certified specialist who has dedicated over 20 years to mastering the nuances of bariatric revisions.
Why Consider Revisional Surgery?
Over time, some patients may experience changes that make their original procedure less effective or comfortable. Common reasons to consider revisional surgery include weight regain, difficulty maintaining portion sizes, or complications such as severe acid reflux (GERD).
Reflux after certain bariatric procedures can significantly impact quality of life, causing discomfort, difficulty eating, or long-term damage to the esophagus. Revisional surgery offers a way to address these issues, restoring function and helping patients feel more comfortable while supporting sustainable weight loss.
Dr. Garth Davis approaches revisional surgery with compassion and expertise, tailoring each plan to your unique needs. Revision isn’t a sign of failure, it’s a way to refine your surgical tools, optimize your health, and ensure long-term success on your weight loss journey.
Every patient's anatomy and history are unique. Dr. Davis will work with you to determine the best path forward. Common revisional options include:
Sleeve to Bypass Conversion: The most popular choice for patients dealing with weight regain or GERD.
Lap-Band Revision: Removing a slipped or ineffective band and converting it to a sleeve or bypass.
Bypass Refinement: Adjusting the size of the gastric pouch or the length of the bypassed intestine.
SADI-S Conversion: An advanced option for those needing a more powerful metabolic boost after a sleeve.
For many patients who initially chose the Gastric Sleeve, a conversion to a Roux-en-Y Gastric Bypass is the gold standard for revision. There are two primary reasons patients seek this specific revision.
Severe Acid Reflux (GERD): The gastric sleeve can sometimes cause or worsen chronic heartburn. A gastric bypass is a highly effective treatment for reflux because it reroutes stomach acid away from the esophagus.
Weight Regain: If the sleeve has stretched or the hormonal "reset" has faded, the bypass adds a malabsorptive component that helps restart weight loss.Lap-Band Revision: Removing a slipped or ineffective band and converting it to a sleeve or bypass.
Reshaping the Pouch: The top portion of your sleeved stomach is partitioned to create a new, smaller gastric pouch.
Rerouting the Intestine: A section of the small intestine is connected directly to this new pouch.
Bypassing the Rest: This "Y" shape allows food to bypass the majority of the stomach and the first part of the small intestine, reducing calorie absorption.Dr. Davis uses careful, laparoscopic and robotic surgical techniques to keep recovery smooth.

Before:
With Dr. Davis, the process starts by getting to know you, your health history, your goals, and what you hope this journey brings. You’ll complete a few medical tests (such as blood work and possibly an EGD), review a simple nutrition plan, meet with our team’s dedicated dietitian, and talk through what realistic progress looks like. We take our time and make sure every question you have is answered.
During:
The procedure itself is minimally invasive and done under general anesthesia. Most surgeries take about 1–2 hours. Our team stays closely connected to you throughout the entire process so you feel safe and supported.
After:
Most revisional weight loss surgery procedures are done on an inpatient basis, so you’re able to return home within 1-2 days. From there, you’ll begin a gentle, guided transition to new foods over the coming weeks. Your follow-up visits will focus on nutrition, vitamin support, and helping you ease back into comfortable movement. Our team stays with you well beyond surgery, supporting, encouraging, and walking with you as your health continues to evolve.
You may be a candidate for revisional surgery if you:
Have experienced significant weight regain after a sleeve, band, or bypass.
Suffer from chronic, severe acid reflux that doesn't respond to medication.
Experience complications like a slipped band or a dilated (stretched) pouch.
Are committed to a renewed focus on nutrition and lifestyle changes.
You’re ready to follow lifelong diet and lifestyle changes after surgery.
The best way to know is a private consultation with Dr. Davis. We review your health, tests, and goals and explain options without pressure.
A revision weight loss surgery procedure is about more than just shedding pounds, it’s about restoring a patient's quality of life. Many patients experience immediate and lasting relief from GERD (painful acid reflux and heartburn), while also jumpstarting weight loss to overcome plateaus and reach their target goals. The procedure can lead to meaningful metabolic improvements, helping regain control over Type 2 diabetes and high blood pressure. Beyond the physical benefits, there is also the invaluable “peace of mind” that comes from having the right surgical solution and a dedicated team of Houston experts supporting you every step of the way.
