Semaglutide, which can be titrated up to 2.4 mg per injection, was studied purely for weight loss. How effective is the new drug compared with other weight loss drugs and surgery? We hope that the drug will supply this signal so that they can eat smaller portions. The reason why some people eat more isn’t because they have less willpower, it’s because they aren’t getting a signal that other people get when they eat. The hormone supplies a signal that some people don't seem to get on their own.
#WEIGHT LOSS MEDICATION FULL#
People who use this type of medication are able to feel full with smaller portions and they are less hungry, which induces weight loss. GLP-1 receptor agonist medications provide a steady supply of this hormone.
We have found that levels of this hormone increase after bariatric surgery, which may be one of the reasons people can eat less food and feel satisfied. Part of my research at Columbia involves understanding appetite, and one way we do that is by measuring people’s GLP-1 levels. But you can do a lot of damage in just 15 minutes, before your body has time to release enough of the hormone to slow gastrointestinal motility and tell the brain to stop eating. Typically, it takes about 15 minutes for the body to release GLP-1 naturally when you eat. It was later found that the hormone also slows down gastrointestinal motility, which helps us feel full, and acts on appetite centers in the brain to decrease hunger. Initially, GLP-1 receptor agonists were developed to treat type 2 diabetes. These medications mimic GLP-1, a hormone that our body makes when it senses there is food in the intestine, helping the pancreas make insulin when glucose levels are high. It belongs to a class of drugs that's been around for quite a number of years. The new drug, semaglutide, is a GLP-1 receptor agonist. We spoke with Korner to learn more about the new drug and what people should keep in mind if they are considering the drug to help them lose weight. (Both groups also dieted and exercised.) In comparison, average weight loss with other medications is 4% to 11%.
#WEIGHT LOSS MEDICATION TRIAL#
In a 68-week placebo-controlled trial of nearly 2,000 participants with a body mass index of at least 27, the semaglutide group had an average weight loss of nearly 15% versus 2.4% in the placebo group. The medication received FDA approval earlier this summer.
#WEIGHT LOSS MEDICATION SKIN#
Now, people who are trying to lose weight have a new option-a medication called Wegovy (semaglutide) that is injected under the skin once a week. “Obesity is a heterogeneous disease with many different causes, and what helps one person lose weight may not work well for another person,” says endocrinologist Judith Korner, MD, PhD, professor of medicine at Columbia University Vagelos College of Physicians and Surgeons and director of the Metabolic and Weight Control Center at Columbia. But while the number of people trying to lose weight has risen in recent years, one national study has found that two-thirds of those who lose weight rapidly regain the weight. Weight loss has been shown to reduce that risk.
