Not Simply Weight Loss: 8 Circumstances Medication Like Wegovy Would possibly Deal with

The burden-loss jab Wegovy made its debut on June 4 2021. It was the primary new weight-loss drug to be accepted by the US Meals and Drug Administration since 2014.

There was quite a lot of pleasure for the reason that launch. Not solely is the drug extraordinarily efficient (folks lose about 15 % of their physique weight in a 12 months), it additionally seems to have many advantages past simply weight reduction.

It is price noting that the drug (generic identify: semaglutide) was first used to deal with diabetes, and certainly continues to be a blockbuster diabetes drug. In order that’s two advantages already. Let us take a look at among the different potential advantages. Listed here are eight (and the checklist is not exhaustive).

1. Knee osteoarthritis

Knee cartilage is just not designed for prime stress masses. People who find themselves obese or overweight are at a better threat of creating osteoarthritis due to the additional stress on their knee joints, with many individuals ultimately requiring knee-replacement surgical procedure.

A latest research, revealed within the New England Journal of Drugs, adopted a gaggle of 407 overweight folks with knee osteoarthritis for 68 weeks. A few of the group acquired semaglutide and a few a placebo. Each teams additionally acquired counselling on bodily exercise and a reduced-calorie weight-reduction plan.

The group that acquired semaglutide (versus a placebo), reported an enormous lower in ache from 71 to 42 factors on an ordinary ache scale (zero to 100, the place a bigger quantity equals extra ache). In addition they reported higher mobility. The identical was not skilled within the placebo group.

The explanations for the advance are most likely because of the speedy weight reduction mixed with the anti-inflammatory properties of semaglutide. It is not clear, although, if semaglutide would have the identical impact on folks with knee osteoarthritis who aren’t overweight.

2. Fatty liver illness

About one in 4 folks, globally, has fatty liver illness – a long-lasting liver situation that may progresses to cirrhosis (liver scarring). Within the late levels, it may be deadly.

Preliminary scientific trial knowledge has proven very promising outcomes with semaglutide, with a important discount in liver fats of 31 %. In one other scientific research, fatty liver was fully resolved in a 3rd of sufferers after simply 24 weeks.

The subsequent query is whether or not semaglutide can reverse the extra extreme types of fatty liver illness, the place scarring has begun. A number of research are underway to check this.

3. Parkinson’s

In research utilizing mind cells (neurons) in a Petri dish and in mouse fashions of Parkinson’s, semaglutide has been proven to have helpful results on a number of “pathological hallmarks” of the neurological illness.

There may be even a touch that semaglutide may match at slowing the worsening of Parkinson’s in people. A French research, revealed earlier this 12 months, utilizing an identical drug (referred to as a GLP-1 receptor agonist), discovered that the motor abilities of individuals with early-stage Parkinson’s given the therapy confirmed nearly no worsening of signs in contrast with folks given a placebo.

We should watch for the outcomes of present trials to see if semaglutide has an identical impact.

4. Alzheimer’s

Semaglutide might present some safety in folks with Alzheimer’s as many individuals with the situation even have diabetes, suggesting that prime glucose is concerned.

In mouse research and human organoid fashions of Alzheimer’s, semaglutide has been proven to cut back deposits of tau and amyloid (the 2 proteins that accumulate within the brains of individuals with Alzheimer’s). And a latest “meta-analysis” of seven scientific trials of individuals with kind 2 diabetes however undiagnosed Alzheimer’s, confirmed that over three years, 40 percent-70 % of sufferers on semaglutide had a decrease threat of an Alzheimer’s analysis.

On condition that there are at the moment no cures for Alzheimer’s illness, prevention appears to be the most suitable choice, particularly for these at increased threat of the illness (that’s, these with diabetes and weight problems).

5. Power kidney illness

Power kidney illness is irreversible, so managing the trigger is essential. The main reason behind kidney failure is diabetes, the place excessive glucose ranges harm the small blood vessels within the kidneys.

Two latest randomised scientific trials learning semaglutide for 3 to 5 years had been accomplished in 2024 and confirmed {that a} biomarker of kidney harm (microalbumin) was decrease in sufferers taking semaglutide. Sufferers within the semaglutide group additionally had a decrease threat of creating kidney failure (24 %) and a decrease threat of demise (20 %) over the research interval.

6. Addictions

The GLP-1 system that semaglutide depends on for its results is thought to be concerned within the neurobiology of dependancy. Certainly, in research of mice fed alcohol, semaglutide lowered binge consuming within the rodents.

And preliminary knowledge in folks with alcohol use dysfunction given semaglutide or a placebo, discovered that these on semaglutide had “higher reductions in consuming amount and heavy consuming” in contrast with these within the placebo group.

And a new research from Sweden confirmed that folks with alcohol dependence had been a lot much less prone to be hospitalised on account of bodily sickness when utilizing semaglutide.

These research recommend semaglutide might present an alternate therapy choice for folks with dependancy issues.

7. Coronary heart illness

As glucose-lowering medication akin to semaglutide decrease an individual’s cardiovascular threat by 14 % in folks with diabetes, the usage of semaglutide has been studied in a spread of coronary heart illness circumstances.

A scientific research confirmed that sufferers with present heart problems who’re overweight or obese, however with out diabetes, taking semaglutide for as much as 4 years confirmed decrease charges of coronary heart assault and stroke over a 3 and a half 12 months interval.

Additionally, in a research of over 4,000 folks, weekly semaglutide considerably lowered coronary heart failure, clogged arteries and demise from any trigger, in contrast with a placebo. On account of these findings, the US Meals and Drug Administration accepted semaglutide to assist stop life-threatening cardiovascular occasions in folks with present coronary heart illness who’re both obese or overweight.

8. Lung issues

Due to semaglutide’s wider protecting properties, akin to its anti-inflammatory options, it has been studied in numerous lung issues.

In a mouse mannequin of acute lung damage, the place unregulated irritation happens resulting in excessive demise charges, semaglutide lowered lung swelling, irritation, white blood cell infiltration and cell demise.

A massive evaluate of 28 scientific research confirmed that semaglutide therapy led to an 18 % discount within the improvement of respiratory illnesses.

A scientific trial is underway to review the safety supplied in sufferers with superior interstitial lung illness, which contains a lot of lung issues (over 200) the place there may be harm to the tissues between the small air sacs within the lungs (alveoli) and the blood vessels round them, inflicting irritation and scarring (fibrosis).
