Operations for the treatment of obesity began to carry out through the mouth
American and European surgeons are experiencing how to conduct operations to reduce the stomach through the mouth. Such access by the intervention, aimed at combating obesity, leaves no cosmetic defects.
With gastroscopy, introduced through the esophagus, stomach superimposed surgical staples in such a way that it formed a thin channel, slowing the passage of food. This patient feel full after taking small amounts of food and lose weight.
Doctors called the preliminary results of 200 operations in the U.S. and 100 in Europe are promising. After about 18 months after the intervention the mean weight loss of patients was 45 percent. According to the surgeon Nishi Gregg (Gregg Nishi) of the Medical Center Sidars-Sinai, only one operation was complicated by perforation of the esophagus, the more serious complications were observed.
The new operation was another achievement of technology NOTES (Natural Orifice Transluminal Endoscopic Surgery – Endoscopic surgery through natural openings). Today in the world with the help of this technology has successfully removed the appendix, gall bladder and kidney through the vagina, through the mouth performed appendectomy and biopsies of the pancreas.
Fighting obesity: two in one
November 13, 2009
One of the coaches Hollywood celebrities helping them throw off excess weight, and along with their pets.
Fitness guru from Beverly Hills, Gunnar Peterson (Gunnar Peterson), known as the man to help stay in shape, such celebrities as Jennifer Lopez and Sylvester Stallone, has created a series of videos for training people with their dogs and cats.
“It is about maintaining the physical form along with your favorite” – said Peterson of Los Angeles – “We have become less and less time, so we combined the two in one”.
And just in time. Veterinarians say that with an increase in waist increases the mass of people and, accordingly, worsening the health of furry friends.
“Just as we have become a nation of fat people, we bring up in his lap” nation “ozhirevshih pets,” – said Dr. Ernest Ward (Ernest Ward), president of the Association for Pet Obesity Prevention (APOP), a group of physicians involved in against obesity in animals.
“Over 44 percent of dogs and 57 percent of cats by today’s estimates, are overweight or obese” – he said, referring to recent studies APOP.
In an interview from Calabash, North Carolina Ward added that when he graduated from veterinary school 17 years ago, obese animals was not a problem.
Chewing gum helps to control appetite

Chewing gum helps to control appetite
Sugar-free gum may help not only the teeth and gums, but also helps to control feelings of appetite, lowering calories and reducing cravings for products harmful to the waist, say researchers Pennington Biomedical Research Center and Louisiana State University / USA.
Studying the properties of chewing gum showed that it prevents the consumption of various snacks during the lunch hour for a total of 40 calories, and sweet food – to 60 calories. When the volunteers chewed gum between snack and lunch time, the feeling of hunger significantly suppressed, and the desire to eat something fatty, salty or sweet to waste.
The experiment found that chewing gum can increase the energy levels is between noon and lunch break, but also eliminates feelings of sleepiness during the same period of time. According to nutritionists, even small changes in caloric intake had a significant influence on the shape and overall health in the long term. Experts believe that chewing gum without the sugar content can serve as a simple way to control appetite.
Fat cells in the human body

No diet can not change the number of fat cells in the human body, Swedish researchers suggest
Researchers Carolina Institute in Sweden say that the final number of fat cells in humans is formed during adolescence and does not change until the end of life, regardless of the recruited or lost weight.
Increasing the number of people suffering from obesity has led to the focus of scientists – fat cells, the effects of which we notice in our stomach.
When we tolsteem, these cells actually increased in size.
However, according to the journal Nature, scientists could not say for sure whether obesity is only a “broadening” fat cells and also to increase their numbers.
If the latter assumption is confirmed, this would mean that slimming could lead to a reduction in the number of fat cells in the body.
Swedish researchers conducted a study involving several hundred children, adolescents and adults of various ages and found that the number of fat cells grown in childhood, but, having reached a certain number during puberty, remain unchanged.
The researchers also tested the hypothesis that the number of fat cells can be changed in extreme circumstances. To this end, they took samples of fat in patients, in particular, had planned to make a plastic operation to remove fat.
Once people lose weight, researchers took a new piece of fat to see whether the number of fat cells.
It is difficult to lose weight
“This explains why so difficult to lose weight and more it is not to recruit – the very fat cells do not disappear, and require more and more” Kirsti Spadling.
According to lead researcher Kirsti Spadling received data – bad news for wishing to lose weight.
“This explains why so difficult to lose weight and more it is not to recruit – the very fat cells do not disappear, and require more and more” – she said.
Dr. Paul Treyhern from the University of Liverpool believes that the Swedish study is a “solid foundation” for further study of the phenomenon of obesity.
“It would be nice if we could find a way to lose weight by altering the number of fat cells, but there are lots of other, the primary options, such as diet and exercise” – felt Treyhern.
According to him, “the real benefit of [the study] is that it has provided us with evidence that we can use in the future to study obesity and its causes.”
“We know that in many tissues of adult cells, which contain no fat, but may begin to accumulate it, with some modification of diet”
Stephen O’Reilly,
University of Cambridge
However, another scientist, Professor Stephen O’Reilly from Cambridge University said that the idea of a constant number of fat cells in adults do not think it credible.
“We know that in the tissue of adults there are many cells that do not contain fat, but may begin to accumulate it, with some modification of diet,” – says O’Reilly.
“You can almost say with certainty that the cells do so without being divided, and therefore they could not” count “using a similar technique. I think it is premature to conclude that by the time of puberty” game is over “- in meaning the number of fat cells, which we will have. “
