Wegovy is among the new technology of weight-loss medicine proving so well-liked that Britain faces a scarcity, only a few months after they got here on to the market.
It’s simple to see why these fighting their weight are determined to pay money for Wegovy (which additionally comes as a lower- dose model, identified Ozempic): in trials, some volunteers misplaced a fifth of their physique weight in a 12 months. The drug is taken within the type of a once-a-week self-administered jab.
However what exactly does it do to the physique? Right here main skilled Wasim Hanif, a professor of diabetology and endocrinology at College Hospital Birmingham, reveals a number of the optimistic – and unfavourable – results it might have…
HUNGER PANGS DISAPPEAR
At the start, you cease feeling hungry – this is among the first issues Wegovy sufferers discover: their need to eat even their favorite meals vanishes inside weeks.
The drug mimics the results of a hormone known as glucagon-like peptide-1 (GLP-1), which is launched by the intestine after we eat to inform the mind we’re full.
The drug prompts GLP-1 receptors within the mind which register fullness within the abdomen after minimal quantities of meals. In consequence, individuals really feel full even after half a plate of meals.
Considered one of my sufferers says he at all times eats his favorite elements of a meal first now he takes Wegovy, in case he will get too full later.
YOUR DIGESTION SLOWS DOWN
The drug additionally slows the speed at which meals passes by way of the intestine – making individuals really feel full for longer. So whereas it would usually take simply 5 or ten minutes for meals that you simply’ve eaten to depart your abdomen – it might take an hour or extra on GLP-1 medicine.
However there is usually a draw back: research present round one in 100 individuals on the medicine develop gastroparesis (or abdomen paralysis), the place abdomen muscle contractions grow to be too weak to digest meals and go it on to the intestines; this will trigger nausea and vomiting. Round half those that develop gastroparesis additionally grow to be constipated.
YOU BURN MORE CALORIES
Wegovy additionally seems to barely enhance the variety of energy burned at relaxation, however why shouldn’t be totally understood.
HEART HEALTH IMPROVES
Shedding important quantities of weight is clearly good for the guts. Nevertheless it’s thought Wegovy does one thing else apart from – it reduces irritation in blood vessels that may clog them up, slicing the danger of a clot forming that may trigger a coronary heart assault or a stroke.
A research within the New England Journal of Medication final 12 months discovered there have been 20 per cent fewer coronary heart assaults, strokes and deaths in chubby or overweight sufferers taking the medicine than in related sufferers on a placebo.
What puzzled the researchers was that almost all sufferers didn’t attain their most weight reduction till a 12 months or so into therapy – but coronary heart assault and stroke charges began to drop inside weeks of beginning the GLP-1 medicine.
It’s thought the weekly jabs drive down blood sugar and this, in flip, reduces irritation in blood vessel partitions.
These medicine appear to have a direct impact on the guts that reduces the danger of a coronary heart assault.
REDUCES YOUR APPETITE FOR ALCOHOL
Some individuals discover Wegovy curbs their need to drink alcohol. A research at Oklahoma State College, involving 80 heavy drinkers, is what impact weekly injections of semaglutide (the energetic ingredient in Wegovy) or a dummy drug has on consumption over a 12-week interval.
It follows an identical research at Gothenburg College in Sweden final 12 months which discovered that rats given the drug consumed 60 per cent much less alcohol than these not injected with semaglutide.
It’s thought the drug works in an identical solution to the way it does in weight problems – dampening down the ‘reward’ hit that the mind will get when alcohol is consumed and so lowering the urge to maintain consuming.
BLOOD SUGAR LEVELS COME DOWN
Though primarily a weight-loss drug, Wegovy – like Ozempic – can considerably cut back blood sugar ranges by selling the discharge of the hormone insulin from the pancreas.
Insulin takes sugar from the bloodstream into cells to make use of as power – lowering the danger of sort 2 diabetes.
However on the similar time the medicine block the results of one other hormone, glucagon, which is launched when you may have low blood sugar and tells the liver to start out releasing saved sugar and fats to gasoline the physique.
By controlling the discharge of each hormones, Wegovy can stabilise blood sugar ranges.
MAY LEAD TO UNPLEASANT BURPS
Anecdotal stories from the U.S. – the place Wegovy-like medicine for weight problems and kind 2 diabetes have been in use for for much longer than within the UK – counsel some customers can develop foul-smelling ‘rotten egg’ burps.
It’s not precisely clear why this occurs, however one risk is Wegovy will increase the variety of sulphur-producing micro organism within the intestine, by altering the microbiome (the neighborhood of micro organism, viruses and different microbes that dwell there), or as a result of meals lingers for longer than regular – inflicting extra disagreeable aromas – as a result of the drug slows the gastric-emptying course of.
YOU MIGHT AGE MORE QUICKLY
Whereas Wegovy would possibly profit your waistline, it may have the alternative impact in your face.
There have been stories of accelerated facial ageing – extra wrinkles, saggier pores and skin – after a number of months on the drug because of the speedy, important weight reduction.
Facial fats smooths out wrinkles and cushions the pores and skin; when it disappears, the pores and skin can seem like extra saggy attributable to decreased ranges of collagen – the fibrous tissue that provides pores and skin its power and adaptability.
It’s one in all issues individuals discover as soon as they’ve misplaced about 15 per cent of their physique weight.
YOUR LIVER SLIMS DOWN
You received’t essentially discover it, however injecting Wegovy as soon as every week is prone to be doing all of your liver the world of excellent.
That’s as a result of some proof suggests it additionally combats fatty liver illness, a build-up of fats across the liver which kills round 10,000 individuals a 12 months within the UK.
Non-alcoholic fatty liver illness (the place fats from weight loss program damages the liver reasonably than booze) has emerged as main well being downside within the UK lately and now accounts for a major variety of liver transplants attributable to sudden liver failure.
AND YOU FEEL MORE ENERGETIC
As soon as the surplus weight begins to drop off, Wegovy sufferers begin to expertise much more get-up-and-go.
Power ranges are typically very low in people who find themselves chubby or overweight and that’s partly as a result of oxygen ranges within the blood are decreased.
That is regarded as attributable to the truth that inhaling overweight individuals is affected by the additional weight, lowering the quantity of oxygen stepping into the bloodstream and rising ranges of carbon dioxide.
Individuals could not discover a lot distinction within the first three months, however as soon as they begin to drop a few pounds they inform me their power ranges enhance.
WAVE GOODBYE TO SNORING
Heavy loud night breathing is a standard grievance amongst people who find themselves overweight.
Extra fats across the neck can put strain on the airways when somebody is mendacity down asleep and this will result in a situation known as obstructive sleep apnoea – the place respiratory is repeatedly interrupted each few seconds, jolting individuals awake and leaving them excessively drowsy through the day. Sleep apnoea is linked with an elevated danger of coronary heart assaults.
Wegovy helps by lowering fats across the neck.
EVEN YOUR FINGERS GET SKINNIER
Many discover even wrists and fingers can slim down. Final summer season social media was filled with tales of previously overweight sufferers searching for modifications to wedding ceremony and engagement rings that now not stayed in place attributable to their radical weight reduction on Wegovy or related medicine.
POSSIBLE LINK TO SUICIDAL THOUGHTS?
Ever since Wegovy and related medicine first emerged, there have been issues over their attainable psychological results in some individuals.
In July 2023, the European Medicines Company revealed it had acquired 150 stories of sufferers on the medicine experiencing ideas about suicide or self-injury.
Shortly afterwards, the Medicines and Healthcare merchandise Regulatory Company – the physique that vets drug security within the UK – revealed that it, too, had acquired a number of related stories.
Nevertheless it’s nonetheless not clear if the medicine are responsible or whether or not it’s attributable to pre-existing circumstances in some sufferers.
A serious research by researchers at Case Western Reserve College of Medication, Cleveland, Ohio – printed within the journal Nature final week – appeared on the data of 1.8million individuals who have taken these sorts of medicine and concluded there is no such thing as a proof that they’re linked with a rise in suicidal ideas.
Despair can happen in extreme weight reduction anyway as some sufferers wrestle with not with the ability to eat what they need any extra.
