This New Smart Pill Can Vibrate To Make You Feel Full

Researchers are exploring a groundbreaking approach to tackle obesity without resorting to conventional medications or surgery. A recent development involves a vibrating pill named the Vibrating Ingestible BioElectronic Stimulator (VIBES), which, in experiments with pigs, demonstrated a significant reduction in food intake and triggered satiety hormones.

The pill, about the size of a large multivitamin, contains a vibrating motor and a silver oxide battery, enclosed by a gelatinous membrane. Once swallowed, stomach acids dissolve the membrane, completing the electronic circuit and activating the motor.

The mechanism leverages the concept that when a muscle experiences vibration, it creates the sensation of being stretched farther than it actually is. In the stomach, this stretching, termed distension, triggers the release of hormones signaling satiety. Researchers aimed to replicate this effect artificially to influence hormone release patterns following a meal.

Testing their invention on young Yorkshire pigs with a digestive system similar to humans, researchers observed a 40 percent reduction in food intake over a two-week period. The pigs, though juveniles and still growing, did not lose weight, but those with the vibrating pill gained weight more slowly than the control group. The device demonstrated no harm to the animals, passing through their digestive systems within four to five days.

While the vibrating pill presents a potential alternative to existing weight loss strategies like surgery and medications, questions persist. Concerns include whether individuals would be willing to take the pill before every meal and how it would feel to have a vibrating pill in the stomach. Furthermore, the possibility of the brain adapting to the illusion over time raises uncertainties about long-term effectiveness.

Study co-author Shriya Srinivasan from Harvard University sees the potential for the device to be a cost-effective solution, particularly in global health settings lacking access to sophisticated and expensive options. However, challenges remain, and future research aims to address manufacturing scalability, wireless control capabilities, and long-term effects by studying the pills in dogs with digestive systems more akin to humans.

In the words of Srinivasan, “I’d love to see how this would transform care and therapy for people in global health settings.”

While the Vibrating Ingestible BioElectronic Stimulator shows promise in combating obesity, further research is needed to address questions surrounding its widespread adoption and long-term efficacy. The potential for a minimally invasive, cost-effective alternative to current weight loss strategies warrants continued exploration.
