Weight loss | How does embolization is effective in weight loss?


Weight loss preliminary study suggests that a procedure which was used by long time in order to halt stomach bleeding is now offering another way to treat severe type of obesity. According to the study of seven severely obese adults, found that the minimally invasive procedure caused no serious complications. This procedure also spurred some weight loss and patients who used this procedure lost their 13 percent of excess body weight on average over the next six months.

Now it’s not clear that whether or how it could fit in with the current treatments for severe obesity. Those treatments include invasive procedures such as gastric bypass surgery, which alters the digestive tract to limit how much food a person can eat and the body’s absorption of calories.

According to the U.S. National Institutes of Health (NIH) reveals that short-term risks include bleeding and infections and in the long run, people can develop nutritional deficiencies and potentially dangerous hernias. He also adds that embolization could potentially works as an intermediate step between lifestyle changes and weight-loss drugs which have limited effects for severe obesity and gastric surgery.

The approach of this embolization is an extension of a long-used procedure which can be named as gastric artery embolization, where microscopic beads are injected into an artery supplying the stomach. Traditionally, it has been done in emergency situations to stop serious stomach bleeding but this new study has revealed that embolization may also help in weight loss. this study has been conducted on 32 patients who had the procedure for stomach bleeding, found a pattern: Those who’d had the left gastric artery treated lost 8 percent of their body weight, on average, over the next three months and in contrast, patients who had a different artery embolized, lost 1 percent of their body weight.

Dr. Weiss explained that left gastric artery supplies a part of the stomach called the fundus, which produces the hormone ghrelin and ghrelin’s main job is to stimulate hunger. He also adds that our hypothesis is that embolization can helps weight loss by lowering ghrelin production but it’s not proven yet. Dr. Clifford Weiss has planned to present his findings on Sunday at the annual meeting of the Society of Interventional Radiology, in Vancouver, Canada. He stressed that this study is preliminary and it is designed to only to test the safety and feasibility of embolization as an obesity treatment.

Weight loss through embolization is a kind of procedure, that you can ask your local radiologist to do but some centers in U.S. are running the clinical trials of this approach. Dr. Bruce Wolfe, a spokesman for the Obesity Society and a professor at Oregon Health & Science University, in Portland says that what remains to be seen is whether embolization has lasting effects that are actually worthwhile. He added the weight loss in this preliminary study was “modest,” and on par with lifestyle changes and medication not surgery. Dr. Weiss says that embolization, by itself, would be enough. The main goal is to decrease a patient’s hunger and it can be used as a tool to be used with proper diet and exercise. This is not a magic bullet against obesity.
