Countries and international organizations around the world have warned that obesity will become a serious health problem in many countries, and various research units are also committed to how to fight obesity.
The radiology department seems to have nothing to do with obesity gossip, and now it is also a step. At the April 2016 annual meeting of the Society of Interventional Radiology, the intervention of gastric embolism to combat obesity was released. Radiation therapy, the principle is that the bottom of the stomach secretes ghrelin, which promotes appetite and fat accumulation. The weight-loss gastric artery embolism is guided by X-ray images with a catheter in the branch of the artery leading to the bottom of the stomach. Put in a small ball to reduce the blood flow to the bottom of the stomach, so that the ghrelin secreted at the bottom of the stomach is reduced, and the patient can successfully lose weight without having to use a knife like the previous gastric volume reduction surgery.
However, in addition to causing weight gain, hunger also regulates many important body functions. Does forcing reduction of ghrelin cause additional side effects? The Johns Hopkins University School of Medicine team conducted gastric embolism in 7 patients with severe obesity. The patient's BMI ranged from 40 to 60, and the body weight and ghrelin concentrations were tracked at 1 month, 3 months, and 6 months after surgery. , hunger and satiety, quality of life survey, blood pressure, and whether there are other side effects.
The results showed that all 7 patients had no significant side effects, and there was significant weight loss after surgery and significant hunger decline, decreased ghrelin concentration, and improved quality of life. In the first month after surgery, the excess body weight decreased by an average of 5.9. %, after 13. months, it decreased by 13.3%. Initially, this new therapy has its effect, but the number of cases in this preliminary clinical trial is too small, and further large-scale clinical trials are needed in the future to further confirm its effects and side effects.
At the 2016 annual meeting of the American Endocrinology Society, two methods to combat obesity were also released.
