Originally designed to treat diabetes, semaglutide has garnered significant attention in recent years for its use in weight loss treatments. The drug mimics a hormone naturally produced in the gut after meals and can trigger a number of similar responses that effectively trick the body into thinking it is full.
Hours of research by our editors, distilled into minutes of clarity.
Semaglutide, the key ingredient in Ozempic, is proving to be more than just a diabetes and weight loss drug. Research suggests it may also help prevent strokes, improve heart health, and slow Alzheimer’s.
Clinical studies show GLP-1 drugs, including semaglutide, promote weight loss through a number of effects. These include reduced appetite, slower emptying of the digestive tract, increased insulin production, and more.
We’ve all heard about these new weight loss drugs. But what are they actually doing inside the human body to help people manage their weight? Health news site STAT has created a clear, concise video that explains what GLP-1 RAs are and how semaglutide works.
It’s well-established that drugs which mimic the hormone GLP-1 can help people lose weight and control blood sugar levels, primarily through appetite reduction. This technical review provides an overview of how both natural and therapeutic GLP-1 interacts with the gut and brain to produce its effects.
Scientists studying the barely-there feeding frequency of the Gila monster found its saliva had a hormone regulating blood sugar and appetite. Further research revealed this hormone resembled a human one known as GLP-1, giving rise to the modern wave of diabetes and weight-management drugs.
Around 75% of prescriptions for GLP-1 drugs are used to treat diabetes, while the remainder is used for weight loss. This overview from GoodRX includes a list and overview of currently available options along with prices for each.
In the US alone, the percentage of the population meeting the clinical standard of obesity rose from less than 20% to more than 40% over the past three decades. This rise has been matched by many countries across the globe, from industrialized to developing nations.
GLP-1 drugs popularity for weight loss and treating diabetes, led to a significant supply shortage and the rise of compound pharmacies, which produce customized drug formulations but lack formal approval from regulators. The drugs are ostensibly the same, but manufacturing methods lead to variations in concentration, filler compounds, and more.
Tirzepatide, like semaglutide, is a GLP-1 drug used in diabetes treatment and for weight loss. Unlike semaglutide, it also acts on glucose-dependent insulinotropic polypeptide (GIP) receptors, proving a second route to reducing appetite as a means to treat diabetes and promote weight loss.
In 2023, Americans spent more than $50B on weight loss drugs, a number expected to triple by the end of the decade. However, because of the wide range of obesity-linked health issues, widespread adoption of the treatments could transform the wider economy.
