Types of Bariatric Surgery: By the Numbers and What It Means



Recommended Posts

The Numbers Task Force of the American Society for Obesity and Metabolic Surgery (ASMBS) has released its most recent numbers on the most common types of weight loss surgery in the U.S. The “ASMBS Bariatric Surgery Numbers Estimation 2016” shows figures for total procedures, plus a breakdown of each type. You can compare the values annually going back to 2011.



How many surgeries were done?

The data show that there were 215,666 total bariatric procedures done in 2016. That is a lot if you compare to 2011 – it is an increase of 36.5% over the course of 5 years, but it is not much if you compare it to the over 20 million Americans who are eligible for bariatric surgery based on criteria of a BMI over 40 or a BMI over 35 plus a related condition. In fact, only 1% of eligible Americans get weight loss surgery.

Why is the gastric sleeve taking over?

The gastric sleeve is gaining momentum, and quickly. It has leaped from 28,124 procedures in 2011 to 125,318 in 2016. It has jumped from making up 17.8% in 2011 of the total to 58.1% in 2016. Why has the gastric sleeve become so popular, so quickly?

  • There is a lower risk of nutrient deficiencies and dumping syndrome compared to gastric bypass.
  • It helps fight hunger by lowering levels of the hormone ghrelin.
  • It is relatively safe for higher-BMI patients.
  • It has similar weight loss as gastric bypass, and lower reoperation and complication rates than gastric band.

Why would anyone not choose the gastric sleeve?

The gastric sleeve may appear to be the choice du jour according to the numbers, but even so, not everyone chooses it. These are some hesitations with the gastric sleeve.

  • It is so new that there is no long-term research on it. We just do not know if it stays effective for years and decades.
  • It is permanent. Done. There is no going back, even if the patient really, really begs.
  • Some patients have trouble getting enough calories and Protein and continue to depend on supplements for a long time post-op.

What are the non-sleeve choices?

While 58.1% of patients opt for the sleeve, the other 39.9% do not. In fact, nearly 1 out of 5 patients opt for gastric bypass, and biliopancreatic diversion/duodenal switch (BPD-DS) has held steady at 0.6%. These are some reasons to consider other types.

  • The gastric bypass has a long history. It can be successful long-term with weight loss, and it is famous for its ability to resolve diabetes quickly.
  • The lap-band is reversible. Even though the band has dropped 86.93% since 2011, there were still 7,310 new bands in 2016.
  • The BPD-DS may still be the best for higher-BMI patients.

What does the research say?

Good news – weight loss surgery works! At least, that is what the majority of the research studies conclude, whether they are looking at the sleeve, bypass, band, or another method. All surgery types have a risk of complications, and all have a risk of mortality of under 1%. BMI can drop 7 to 14 or more kg/m2, and diabetes, sleep apnea, hypertension, and other obesity-related conditions can get better.

Is the gastric balloon going to be a factor?

Time will tell whether the gastric balloon is going to be a factor in the overall bariatric surgery statistics. The FDA approved it only in 2015, and it jumped from 0 in 2011-2014 to 0.3% (700 procedures) in 2015 to 2.7% (5,744 procedures) in 2016. The balloon is not a true bariatric surgery; it is not permanent, it leads to less weight loss, and it is intended for lower-BMI patients. This means that it may not be in competition with the true bariatric surgery procedures, although it is likely to become more common as it becomes better known.

What is the deal with so many revision surgeries?

If weight loss surgery techniques are always advancing, why are revisions becoming so much more common? They comprised 6% (9,480) of the total in 2011, but 13.9% (30,077) in 2016. It could be because some of the previous (failed) surgeries were done using older techniques, and are now ready for serious help – a revised procedure.

Why are 99 out of 100 eligible Americans not getting Weight Loss Surgery?

There are a lot of reasons eligible Americans are not getting Weight Loss Surgery. They include:

  • Cost.
  • Fear of complications or death.
  • Not knowing where to start.
  • Lack of support from family, friends, and healthcare providers.
  • Fear of failure.
  • Lack of long-term commitment to lifestyle changes.

What can health professionals and patients do to help eligible patients get the Weight Loss Surgery they need?

Surgeons and other bariatric professionals can help by making sure they reach out to eligible patients. They can explain their options, and promise to provide the nutritional and psychological support patients need for success and to feel confident in their success. They can organize support groups and provide additional resources for patients to get advice and encouragement anytime.

What can health professionals and patients do to help eligible patients get the Weight Loss Surgery they need?

Patients can do their part by asking questions to learn about their best options. They can express their doubts and fears to surgeons to come up with strategies for success. They can reach out to friends, acquaintances, and online groups for support.

This post is very interesting and helpful. It confirms to me that lap band surgery is not advisable. It also confirms the increasing popularity of sleeve surgery. I still think that the RNY bypass is the best action for me to take. I think many of the sleeve surgeries will end up with disappointing results and many will require revisions to bypass.

The sleeve is not a NEW surgery. It has been around since the beginning of weight loss surgery. It was part of a two step process then. It was the first step. The actual gastric bypass was performed after the patients lost a sufficient amount of weight from having the sleeve. [emoji16]

very interesting statistics!

I wanted to add that I am very happy that the number of bariatric surgeries is increasing every year. Nowadays obesity is a real problem, and a lot of people are suffering from this disease. That's amazing that it can be cured thanks to bariatric surgery. There are 616 surgeries only in my region, and it's really cool. I think that it's a good sign, because I have read on https://www.sunsigns.org/angel-number-616-meaning/ that it's a very powerful angelic number, with a hidden meaning. This number means something really good, and I am really happy about it.

      I am almost 8 weeks post op and I am down to 157 from 202. I have been struggling with nausea but not vomiting. Anyone else having this happen?

        After having horrendous nausea I did some reading and it seems quite common. Especially if you have ruled out eating too fast/too big a mouthful. Also drinking too soon will make you feel sick. I now take 2 antiemetics to help with my nausea, hopefully yours is just that you need to slow down eating etc

      2. BayougirlMrsS

        agree with the above. start a log of what and when you eat/drink

      3. zombierayvinn

        Thank you. I get the nausea throughout the day and night its kind of weird.

      4. BayougirlMrsS

        do you set a timer? This is also a hard one or me. During the time between the band removal and sleeve i got back into the habit of drinking with meals..... water, coffee, wine, cocktails.

        I find myself forgetting. In the past months i only threw up twice... so thats good, but i have felt nausea a few times. So now i set a timer on my phone or if im home, i use Alexa.

        What state are you in????

    • Krestel

      Officially no longer over weight! Goal #1 reached! I'm now under 80kgs (176 lbs) at 179cm (5'10") and 10 months post-op and am over the moon. My weight at 79.9 kgs (176 lbs) gives me a BMI of 24.9 which means that I have a normal weight! OMG.
      I still want to lose about 16 lbs more though in order to get safely into the middle range to insure against that little regain that happens. The I have maintenence in front of me as well.
      BUT I have hit my first goal. Yeah me!!!
