Obesity has become a leading cause for concern in the US. In America alone, there are over one-third of people in the US who are obese. On a global note, there are an estimated 4 million individuals who died due to conditions related to a high body mass index (BMI) in 2015.
These trends related to obesity are worrying the scientists who are focusing on understanding the risk factors, causes, and impact of obesity. They understand that there are a plethora of reasons behind obesity. These include hormonal, genetic, and psychological factors among others.
The direct reason behind too much weight, however, is the consumptions of more calories than the body can use. To bring that under control though, a recent paper has come up with a battery-free implant that can control the hunger feelings in the body.
What Does the Findings Propose?
Researchers from the University of Wisconsin-Madison understand that since excessive hunger sits at the center of the problem, it should be corrected. Consequently, the researchers have come up with a high-tech solution to deal with the problem.
The scientists have come up with a small, implantable device, which they hope can help lessen hunger pangs. As excessive hunger reduces, one can bring down his weight digits significantly.
This new device is less than one centimeter in size and can be planted into the body using a minimally invasive technique. It works to send small electricity pulses through the vagus nerve to the brain. This nerve is responsible for sending messages between the stomach and the brain.
The device will send mild signals to the brain, which will convince it that the stomach is full. Consequently, it will aid in slashing hunger feelings. The interesting part is that the device will only stimulate the brain when there is food in the stomach.
This is because the small implant is not powered by battery or charging. Instead, it is powered by the churning motion in the stomach that occurs in the event of peristalsis. In simple words, the device is active only when there is food in the stomach, which means it will stop a person from overeating as the stomach signals the brain that it is full and is not hungry.
The author termed their findings as effective as they outlined, “We successfully demonstrated this strategy on rats and achieved 38 percent weight loss in as short as 15 days without further rebound, exceeding all current electrical stimulation approaches.”
Summing Up – Are There Any Possible Side Effects
There were no apparent side effects in the trial. The implant stayed in the correct position throughout the investigation’s 12 weeks. Plus, there were no measurable negative impacts on the subject’s (rats) liver and kidney. Moreover, there were no signs of infection.
What’s more, the scientists also conducted a postmortem examination on most of the rats’ vital organs. They found that there were no adverse effects. Thus, it can be said that this new tiny implant gives us substantial hope for weight loss.
