Researchers develop a vibrating, ingestible capsule
People may quickly shed pounds by swallowing a vibrating tablet earlier than each meal, scientists say.
Researchers on the Massachusetts Institute of Technology have developed a multivitamin-sized capsule that methods the abdomen into pondering it’s full.
In animal experiments, pigs that took the tablet 20 minutes earlier than consuming consumed 40 % much less meals on common in comparison with a management group.
The gadget is but to enter human trials, however the researchers say it had a ‘profound’ impact on urge for food and will supply a approach to ‘shed pounds or management urge for food’. They say it additionally lacked negative effects like nausea and vomiting, that are seen in Ozempic.
The above graphic reveals how the vibrating tablet may very well be used to assist curb urge for food and spur weight reduction. It works by vibrating contained in the abdomen to trick the organ into pondering it’s full, inflicting it to ship alerts to the mind that suppress urge for food
Researchers on the Massachusetts Institute of Technology discovered vibrations from the gadget tricked the abdomen into pondering it was full. Pictured above is the gadget, named a Vibrating Ingestible BioElectronic Stimulator or VIBES
Dr Shriya Srinivasan, a bioengineering graduate from the college, mentioned: ‘For any person who needs to shed pounds or management their urge for food, it may very well be taken earlier than every meal.
‘This may very well be actually fascinating in that it could present an possibility that might reduce the negative effects that we see with the opposite pharmacological therapies on the market.’
A value for the gadget — referred to as VIBES — is but to be made accessible, however researchers say it may very well be ‘very cost-effective’ when manufactured at scale.
A month’s provide of Ozempic prices about $800 with out insurance coverage, though with protection it will possibly drop to as little as $25.
At current, a brand new tablet could be wanted after each meal. But researchers say they’re additionally engaged on a model that might keep within the abdomen and be operated wirelessly.
Once swallowed, the gadget travels to the abdomen the place it’s activated.
It begins off coated in a gelatinous layer that’s damaged down by acid within the abdomen, activating its circuit and triggering it to start out vibrating.
This, in flip, triggers the mechanoreceptors within the abdomen wall.
Normally, these are solely triggered when the abdomen expands, or turns into distended, after a big meal.
But the vibrations trick them into pondering that the abdomen has already expanded.
They ship alerts up the vagus nerve to the mind which prompts the organ to set off the discharge of hormones to sign satiety and suppress urge for food.
The tablet prompted the discharge of fullness hormone GLP-1 — the identical method Ozempic, Wegovy and others suppress urge for food.
The receptors within the abdomen additionally sign to the mind to set off the discharge of the hormone C-peptide, which is produced within the pancreas and aids digestion, and Pyy, which is produced by the intestines and prompts emotions of fullness.
The capsule vibrates within the abdomen for about half-hour, the researchers mentioned.
In the animal experiments, it then took 4 to 5 days to journey by the intestines earlier than being expelled within the feces.
Wegovy and Ozempic work by triggering the physique to provide a hormone referred to as GLP-1 that’s launched naturally from the intestines after meals

For their experiment, they first offered the pigs with a plate of meals and tracked how a lot they consumed.
In the second, the animals swallowed the vibrating capsule 20 minutes earlier than consuming and have been then given the identical quantity of meals.
Results confirmed after consuming the capsule they ate about 40 % much less on common than if that they had not had the capsule.
Tests on their blood revealed the discharge of hormones which seemed just like the animals had simply had a meal — despite the fact that that they had fasted.
They additionally gained weight extra slowly over durations when handled with the tablet.
Dr Giovanni Traverso, a mechanical engineer concerned within the checks, mentioned the capsule’s affect on urge for food was ‘profound’.
‘We have the potential to beat among the challenges and prices related to supply of biologic medication,’ he mentioned.
Dr Srinivasan added: ‘For a variety of populations, among the more practical therapies for weight problems are very expensive.
‘At scale, our gadget may very well be manufactured at a fairly cost-effective worth level.
‘I’d like to see how this may remodel care and remedy for individuals in international well being settings who might not have entry to among the extra refined or costly choices which can be accessible at present.’
Weight-loss medication like Ozempic have exploded in recognition lately for his or her capability to assist somebody shed pounds with only a weekly injection.
Data reveals there have been greater than 4 million prescriptions for Ozempic, Wegovy and related medication in 2022 — greater than double the lower than 1.5million prescriptions the yr earlier than.
The examine was printed within the journal Science Advances.
