Touted by celebrities, raved about by TikTok users, and advertised by med spas, a new class of drugs for treating diabetes and obesity has exploded in popularity for its weight-loss effects, leading to rippling shortages across several of the medications.

Lilly’s diabetes medication Trulicity has also been in tight supply, according to the drugmaker.
