Allow me to think aloud while I also share some information. When it comes to gastric surgery options there are really three options. (There actually are more but I'm only going to cover three here as they are the most common). Keep in mind this is MY knowledge and therefore is quite fallible. :)
1) Lap Band - This is fully reversible. It is a band (silicone I believe) that is wrapped around the top of the stomach which creates a pouch. There is a 'port' that is just under the skin and your doctor can add additional liquid to tighten the band or remove fluid to loosen the band (if, for example you become pregnant and need to eat more). This is only a restrictive procedure. Plusses: it is reversible, it is adjustable, it isn't a major surgery. Negatives: Requires more 'upkeep' (filling of band) and also the band sometimes embeds in the stomach or other complications requiring either removal of the band or a revision to one of the other options. For the non squeamish
here is a video of an actual procedure.
2) Gastric Sleeve - This is an operation where they remove a portion (approximately 80%) of your stomach - obviously since they remove the portion of the stomach it is not reversible. Everything else stays intact. Once again, this is only a restrictive procedure. The portion that remains resembles a banana and thus it gets it's name of a sleeve. This is a newer procedure. Plusses: No risk of a band imbedding, no 'rerouting' of your intestines, smaller chance of needing vitamins. Negatives: Overall loss not quite what it is for a RNY bypass. Also, since it is a newer procedure it doesn't have a track record. People do also start with a sleeve and then revise it to a RNY for further loss. For the non-squeamish
here is a video of an actual procedure.
3) Gastric Bypass or Roux-en-Y (also seen shortened down to RNY) - This is the 'gold standard' and has been around the longest. A new stomach is created - the stomach is bypassed and a smaller 'stomach' (aka stoma) is created with the intestines. The stoma is connected and rerouted to bypass a large portion of intestines. This reduces absorption of nutrients and calories as well as offering restriction. Plusses: High expected weight loss, has been performed hundreds of thousands of times thus side effects and complications are known, for people who have a problem with sweets - approximately 30% of people having RNY will experience an unpleasant experience deemed as 'dumping' which acts as a further deterrent to sugars offering a better chance of success. Negatives: Major surgery, longer recovery time, side effects of leakage, bleeding, vomiting possible. Because of malabsorption there is a possibility of malnutrition. Thus regular blood tests and daily supplements and vitamins are required.
Here is a video of that procedure as well.
So, which one am I considering?
Well, at first I thought I wanted a sleeve. The removal of the stomach scared me - but it is a straightforward surgery with fewer complications and less followup required. It has a quicker recovery time. And from what I can find it generally produces between a 60 and 70% weight loss (whereas bypass produces around 70%). The sleeve does take a little longer because it doesn't have the malabsorption component but long term (2 years) the amount lost appears to be very similar.
So I went and talked to the surgeon. The surgeon asked about my eating habits. I'm not a binge eater. I actually eat pretty reasonably sized meals and I'm the world's slowest eater. My issues are emotional eating and sweets - added with the PCOS that's not a good combination. Anyways, based on that information the surgeon recommended the RNY. He felt like the 'dumping syndrome' would give me the greatest chance of success. It would address my issues better.
Since, then I've been thinking I wanted RNY. But I was recently studying and found the statistic that only 30% of people actually experience dumping. So I have a much greater chance of it NOT happening. And in exchange I have to be worrying about more complications and more follow-up. These are issues because my health insurance will not cover any expenses related to weight loss surgery of any kind (so I will be out of pocket for any complications, follow up blood work, etc). So, the last few days I've been rethinking which surgery I should have.
This video discusses the two I'm considering and the differences between them.
I guess more research is in order. If anyone reading this has any input I'd love to hear it. :)
