While brand-name weight loss drugs are in short supply, a market for alternatives thrives

Prescription weight loss drugs have become so popular in the United States that suppliers have struggled to keep up. Jean Readdy, a retired teacher living in Sinking Spring, Pennsylvania, is among the one in eight Americans who have tried a GLP-1 drug for weight loss or diabetes, more commonly known by brand names like Ozempic and Wegovy.

Readdy, who has struggled with her weight for most of her life, told CBS News her weight affected her self-esteem and how she moved through the world.

"I didn't like going out places," Readdy admitted.
