The maker of Ozempic and Wegovy is suing a rival firm for selling what it says are unsafe, knock-off versions of its weight-loss drugs in the US. Danish company Novo Nordisk asked US courts on Monday to ban Hims & Hers' range of weight-loss pills and injections, which it says are not approved by US authorities and infringe on its patent. The legal drama began on Friday after Hims & Hers launched a new weight-loss pill, leading to an initial threat from Novo Nordisk. Over the weekend, Hims & Hers said it would stop selling the pill. On Monday, its share price slumped as it called Novo Nordisk's decision to press ahead with the lawsuit a blatant attack.

Fox News contributor Dr. Marc Siegel says the pill stays in the stomach for four to five days and utilizes AI. A vibrating pill has shown promise in early studies as a possible obesity treatment. Developed by engineers at MIT (Massachusetts Institute of Technology), the capsule is intended to be swallowed prior to eating in order to "trick" the brain into thinking the body is full -- thereby reducing the amount of calories consumed. The vibrations activate the "stretch receptors" that detect satiety after eating, sending a signal to the brain that the stomach is full even if it's not. In a study published in the journal Science Advances on Dec. 22, researchers revealed that animals who swallowed the pill 20 minutes before eating consumed 40% less food than those who weren't given the pill, according to a press release from MIT.
