I hesitate to weigh-in, because mine was not exactly bariatric surgery.
In 2003 I had surgery to correct what was thought to be a hiatal hernia. The surgery went bad and due to a perforated stomach in 2005, I had what has been described as a modified Roux-en-Y bypass.
The difference for me is, in a standard Roux-en-Y a small pouch is left, but for me they did a true by-pass, the stomach is no longer in the pipe-line; the esophagus goes straight into the small intestine.
While I have lost weight, most of it was either due to recovery or actively trying to do so. I will tell you truthfully that if I wished, I can gain weight by eating poorly. No, let me state it more precisely: If I do not practice discipline I gain weight. When I return to my old eating habits, I gain weight.
When you sign up, they will make you lose 10% of your body weight (or so I am told) to show that you are serious. IMO, if you can do that, why would you maim yourself? Why not continue to show this kind of discipline?
I can rarely enjoy a normal meal with friends. I have to graze all day in order to eat enough. If I don’t graze on the *right *foods, if I eat the kinds of foods that made me fat to begin with, I gain weight.
I was once over 300 pounds. I am now less than 200.
When I left the hospital in 2005 (after the bypass) I weighed 207 pounds. I was, at one time after that, 264 pounds.
If I had not had the surgery, I cannot tell you for sure that I would ever have made myself lose the weight that I have. I think I would. I lost 40 pounds in 2012. I did that by eating correctly and walking daily.
I am full in just a few bites. And then I am hungry again in 20 minutes. I do not enjoy living this way. At my new job, upon seeing my desk stocked with tuna fish and protein bars and the kinds of things I graze on, the director once announced in front of everyone: I see Khadaji really likes to eat. Yeah, this is fun.
I am now tired all the time. We check my blood regularly and I take potassium, magnesium, calcium, B12 and iron (and a few other things) because I don’t absorb them well. The average bariatric surgery patient will likely not have problems with all of these things, but may have with many.
I can no longer drink like I used to. One or two beers gets me buzzed, but then I sober up quickly too. (Although I miss drinking, this is probably a net gain. )
Chemicals seem to impact me hard. I get confused quickly on most cold meds.
Opinion aside: My surgery for the by-pass was severe, but I did have laproscopic surgery for one of my earlier surgeries and the by-pass surgery should be able to be done laproscopically. Likely you will be up and around that day or the very next and likely you will go home the next day. Pain is minimal and I was off the pain meds within 10 days. If you have it, I expect you will not find the surgery itself to be traumatic. Of all my surgeries, the laproscopic ones were relatively gentle and if I needed to have one again I would do so without fear.
