Answering Your Questions About GLP-1s with Keren Zhou, MD

·48 min·4 clips

GLP-1 usage surged 600% in five years, but what exactly are these medications that help people drop pounds seemingly overnight?

The episode begins with host John Horton introducing the topic of GLP-1 medications, noting their surge in popularity for weight loss. Dr. Kathy Zou, an endocrinologist at Cleveland Clinic, joins to explain that GLP-1 receptor agonists are hormone-based medications that suppress hunger, cause early satiety, and improve metabolic functions like insulin resistance. She traces their history from diabetes management starting in 2005 to recent approvals for obesity. Dr. Zou describes administration as mostly weekly injections with small needles. A key point is that GLP-1s are not short-term solutions; stopping leads to weight rebound and increased hunger. Effectiveness varies by agent, with some like terzepatide achieving up to 25% weight loss. Qualification typically requires diabetes, obesity, or overweight with comorbidities, though insurance coverage varies. Side effects are discussed extensively, including common GI issues like nausea and reflux, which affect up to 70% of users but often attenuate after a few weeks. Rarer side effects include pancreatitis and medullary thyroid cancer warnings. Dr. Zou addresses phenomena like 'Ozempic butt' and 'Ozempic face,' attributing them to rapid weight loss and muscle loss, and emphasizes the need for gradual loss and exercise. She also mentions 'Ozempic teeth' from enamel erosion due to reflux and vomiting. The ideal candidates are people with type 2 diabetes or obesity with comorbidities, especially those with cardiovascular risks, while frail older individuals or those with specific contraindications should avoid them. Dr. Zou stresses that GLP-1s are not magic pills and require lifestyle changes, including nutrition and exercise, for best outcomes. The episode concludes with a discussion on the growing use of GLP-1s across medical specialties and the importance of proper patient counseling.
