Game-Changer Drug Promotes Weight Loss Like No Medicine Ever Seen, Scientists Say – ScienceAlert

Within the easiest phrases, weight problems is the product of a physique’s power output being lower than its power enter. However in actuality, there’s nothing easy about this complex and mysterious disease.


Weight problems, which has skyrocketed in recent decades – now defining the physique mass of over 40 percent of grownup People – is not simply troublesome for people to endure and scientists to understand. It is also extremely exhausting to deal with.

Past dedication to sustained life-style modifications – wholesome consuming and train, successfully – there are actually solely two potential choices that will assist: bariatric surgery and weight-loss drugs.

The previous is invasive and carries varied dangers and issues. As for the medication, they do not at all times work, and might have their own adverse effects too.

Nevertheless, an experimental remedy not too long ago trialled by scientists and detailed in a study printed this week may open new doorways for treating weight problems sufferers with a weight-loss drug.

Within the examine, which concerned nearly 2,000 overweight adults throughout 16 completely different international locations, members took a weekly dose of a drug referred to as semaglutide, an present remedy already used within the remedy of kind 2 diabetes.

A management group took solely a placebo, rather than the remedy. Each teams obtained a way of life intervention course designed to advertise weight reduction.

On the finish of the trial, the members who took the placebo misplaced a small however clinically insignificant quantity of weight. However for many who took semaglutide, the results have been pronounced.


After 68 weeks of remedy with the drug – which suppresses urge for food resulting from quite a lot of results on the mind – members taking semaglutide misplaced on common 14.9 % of their physique weight. And over 30 % of the group misplaced greater than 20 % of their physique weight.

Broadly talking, this makes the drug as much as twice as efficient as present drugs for weight reduction, the researchers say, approaching the type of efficacy of surgical interventions.

“No different drug has come near producing this degree of weight reduction – this actually is a game-changer,” says weight problems researcher Rachel Batterham from College School London.

“For the primary time, folks can obtain by means of medication what was solely potential by means of weight-loss surgical procedure.”

Along with shedding weight, members registered enhancements in different areas, exhibiting reductions in varied cardiometabolic threat components, and reporting high quality of life enhancements.

Whereas the outcomes are compelling, semaglutide dosage for anti-obesity results does include some drawbacks.

Gentle-to-moderate results have been reported by many members (in each the semaglutide and placebo teams), together with nausea and diarrhoea. Whereas the results have been short-term, they have been sufficient for almost 60 of members to discontinue their remedy, in contrast with simply 5 within the placebo group.


At current, the drug requires a weekly injection to work – whereas an oral type of the drugs would doubtless be most popular by sufferers.

Extra considerably, we do not but have knowledge on what occurred to the members after the drug routine ceased on the finish of the trial.

For not less than one particular person, nonetheless, who spoke to The New York Times, her weight started to creep up after the trial was over.

“Whereas medication like this may occasionally show helpful within the quick time period for acquiring fast weight reduction in extreme weight problems, they don’t seem to be a magic bullet for stopping or treating much less extreme levels of weight problems,” says nutritionist Tom Sanders, an emeritus professor at King’s School London, who wasn’t concerned with the examine.

“Public well being measures that encourage behavioural modifications similar to common bodily exercise and moderating dietary power consumption are nonetheless wanted.”

No one would deny the knowledge of that, but when additional evaluation of semaglutide seems to be optimistic, we is also an essential new pharmaceutical possibility to assist fight weight problems.


And that possibility would possibly arrive prior to we expect.

The examine, funded by pharmaceutical firm Novo Nordisk – which sells semaglutide as an anti-diabetic remedy – is now being tendered as proof to worldwide well being regulatory authorities, in help of an software to market the drug as an weight problems remedy.

The US FDA, together with its counterparts within the UK and Europe, is at the moment assessing the information.
