After weight-loss surgery, new gut bacteria keep obesity away

The logic behind weight-loss surgery seems simple: rearrange the digestive tract so the stomach can hold less food and the food bypasses part of the small intestine, allowing fewer of a meal's calories to be absorbed. Bye-bye, obesity.

A study of lab mice, published on Wednesday, begs to differ. It concludes that one of the most common and effective forms of bariatric surgery, called Roux-en-Y gastric bypass, melts away pounds not - or not only - by re-routing the digestive tract, as long thought, but by changing the bacteria in the gut.

Or, in non-scientific terms, the surgery somehow replaces fattening microbes with slimming ones.

If that occurs in people, too, then the same bacteria-changing legerdemain achieved by gastric bypass might be accomplished without putting obese patients under the knife in an expensive and risky operation.

I work in the field and there has been talk of this for a long time.

How many of them become obese again? Almost all the people I know gain their weight beck in about 5-7 years.

Good raw milk helps gut bacteria, too.

A number do gain back. Some of it is behavior.

I wonder whether there is re-infection in the homes with other obese people. Perhaps they need to have booster gut-inoculations of the “skinny” bacteria.

What a Market! if true.

Most of it, I think, is bad advice.

There aren't many people, I think, who are significantly overweight who haven't tried, many times, to lose the weight. The problem is that nearly all the advice they've been getting is simply wrong.

how bout banding or sleeve gastrectomy? and a lot of it is about changing how you eat too as band failures(not losing or keeping off weight) are common if they keep eating like they did before the surgery

In some areas banding has been discontinued because of complications. The sleeve is replacing it, but still needs to have kinks worked out. Not that much of a disfference from the staple IMHO

other than the staples can be removed where once part the stomach is removed, that's it...
