Danish drugmaker Novo Nordisk on Tuesday launched its blockbuster weight-loss drug Wegovy in India, three months after Eli Lilly began marketing its rival product Mounjaro in the world's most populous nation.

With the weight-loss blockbuster drug Wegovy, now in India, renowned endocrinologist and diabetologist Dr. Ambrish Mithal weighs in on who should take it, how it works, and why it's not a shortcut to health.

Some doctors are concerned that patients taking weight loss drugs like Wegovy may be losing too much lean mass. A combination therapy might change that.
