Diagnosed me with bile induced gastritis. Wants to do a gastric bypass. In my 40's,(5'4", 203), but isn't there a less invasive answer?

Diagnosed me with bile induced gastritis. Wants to do a gastric bypass. In my 40's,(5'4", 203), but isn't there a less invasive answer?

Options: Probably theist popular weight loss operation at the moment is a sleeve gastrectomy. Its not really less invasive, but has less potential for long term side effects. There are also some newer endoscopic therapies, but they are not so effective. Ask your doctor if a consultation with a Bariatric surgeon is appropriate. Hope this helps! ...Read more

Weight loss : You may have lost weight on this diet and it may have worked for you ! I don't think it is healthy , because you are missing out on nutrients , because you are eating such low volume of food . Unless you are taking some high powered organic , food supplements , I believe , long term side effects would be hair loss , brittle nails , saggy skin . Rethink this concept . See a dietician and a doctor ...Read more

For what reason wouldn't gastric bypass work on some people?

For what reason wouldn't gastric bypass work on some people?

Gastric bypass fail: In order for a gastric bypass to work, the patient must do their part which is to eat healthy food, eat the right portions, and exercise. The operation helps with eating the right portions, but it doesn't dictate what you eat. You can eat junk food, not exercise, and defeat a gastric bypass. Also, overeating can stretch the pouch and make it easier to eat more food. ...Read more

Had gastric bypass 12 yrsago. Lost 130#. Gains about 95  back.  Would weight watchers work for me. .  Can't afford a revision.?

Absolutely : Yes weight watchers, jenny craig or any of the other weight loss programs would work. It would certainly help if you worked closely with a nutritionist and a trainer at te gym. You proved to yourself already that when you had the right tool and you used it, you lost weight. You simply need to use a new tool to help yourself in the right direction. Good luck. ...Read more

My aunt is having her third gastric bypass. "john doe" bariatrdoctor in this small town is going to do it. Shouldn't she go to more of a specialist?

My aunt is having her third gastric bypass.  "john doe" bariatrdoctor in this small town is going to do it.  Shouldn't she go to more of a specialist?

Revision: Absolutely. Even for a first time gastric bypass, it should be done by someone who is very experienced. A second or third operation is a revision and not only are they difficult, but the risk of complications is much higher. She should be going to a surgeon who specializes in revisions and does them routinely. The average surgeon doesn't usually have that much experience with revisions. ...Read more

I had gastric bypass but didn't follow diet and am now almost back to my before weight. Help.

I had gastric bypass but didn't  follow diet and am now almost back to my before weight.  Help.

Wt gain after bypass: You need to get re-engaged with your weight loss program where you had surgery (assuming they offer a support program). Patients who attend support groups are more successful than those who do not attend. There may also be an anatomical reason why you have gained weight like an enlarged gastric pouch, an enlarged anastomosis, or both, which can be corrected with revisional surgery. ...Read more

Had gastric bypass-gained half of weight list back, but I still can't eat normally, & I seldom get hungry. Can't eat meat or much fruit. Any thoughts?

Had gastric bypass-gained half of weight list back, but I still can't eat normally, & I seldom get hungry. Can't eat meat or much fruit. Any thoughts?

Eat solids, no sips: Weight regain after bypass is usually due to eating foods that go down comfortably. There is a tendency to fall into a pattern o slider foods (soups), sipping with food, and snacks. In essence you are defeating the surgery to lose weight, you need to eat foods that pack the pouch (bread, chicken, etc) and fill you up. Don't drink with or after meals or you will wash food down. ...Read more
