Gastric Bypass Surgery: The Results Explained
So far, Gastric Bypass surgery is most effective (and extreme) weight loss method. Let learn from a research study, what actually happens in our bodies after Gastric Bypass surgery that causes the tremendous weight loss. While we know it is not possible for anyone who needs to lose weight to go through with Gastric Bypass surgery, we can get the similar weight loss benefit without going through the risk of surgery.
To learn how this is possible I wanted to highlight a new research study where they test the effects of Gastric Bypass surgery on mice. Some of the research over the next nine weeks that I want to share with you is very technical, but I’m going to break it down so you don’t feel like you are attending medical school. So, let’s get started!
Process of the Gastric Bypass.
After Gastric Bypass, patients cannot eat large amounts of food at once, so they eat smaller meals more frequently. Previously, doctors thought that this limited intake of food caused by the surgery creating a smaller stomach was the reason why the surgery was effective. However, that is no longer true. Researchers found out there is a change in our body that creates the weight loss. The surgery…it changes the gastric hormone
it changes the bacterial flora in the gut
Interestingly enough that is what we learn from the research study on the mice that I mentioned earlier. That is how…First group of obese mice went through with Gastric Bypass surgery, and they lost weight.
The second group of obese mice were given the bacterial flora (bacteria from the stomach) from the first group of mice. The weight loss in the second group was the same as the first without needing to go through the Gastric Bypass surgery.
Then researchers thought, Aha! There is the change of bacteria causing the weight loss. But why bacteria change? Is that a surgery causing the change? Does portioning the stomach change the bacteria? So they continued their research with a third and fourth group of mice. Mouse after the sham surgery.
Third group of the obese mice were given a sham surgery. (Sham surgery is a gastric bypass surgery but they re-suture everything back to normal. So no actual portioning of the stomach was completed. The stomach is exactly the same size.) The fourth group of obese mice were given the bacterial flora from the third group (after sham surgery). Just had been done in the first and second groups. The result, no weight loss! The Gastric surgery (portioning of the stomach) is changing the gut hormones and bacterial flora (Note: this study only illustrates the bacterial flora) which is resulting in the effective weight loss!!! Voila! Portioning the stomach may help lose weight possibly by all the beneficial changes of the gut’s hormone and flora.Look out for my next article called “Losing Weight with Systematic Portion Control” on Tuesday!
