Just watched a report on BBC news, they did an item on a woman who had type 2 diabetes and was prescribed Mounjaro, doctors were impressed she managed to come off insulin within a month. She had some weightloss and now goes to the gym regularly.

Her doctor admitted that there was widespread concern in the medical field that people who were buying it privately for cosmetic reasons not for medical reasons could face some consequences in the future such as muscle growth and bone degeneration and lack of nutrition - they simply don't have this data at present.

Feel like this is going to be big news in the foreseeable future.

True, but the whole point of WLI is that they ensure weight loss is far more rapid and far greater. So muscle loss is going to be rapid and greater too.

Edited

No, the “whole point” of WLI is to restore GLP-1 levels in the brain and rebalance the body’s responses to sugar, insulin and food in general. It is not to “ensure weight loss is more rapid”.

Sure, some people do find the weight drops off fast, others of us are happily plodding away losing 1lb a week at a dose that suits us. While also appreciating the excellent blood test results and reduction in joint pain from being merely overweight instead of obese.

@BunfightBetty so the biggest concern is people who are accessing prescription only medication fraudulently or illegally who don’t meet the criteria as laid out by the MHRA. I would agree that people who are reckless enough to access POM for conditions they don’t have are likely to cause themselves harm. Although likely only the current known side effects rather than unknown possible future side effects.

I do wonder why the decision making of the MHRA is under doubt for this specific medication and not all of the other medications they rule on.

I have pcos. I know the struggle of weight loss. The weight loss jabs suppress appetite. They don’t do anything magical with metabolisms. Many people have success losing weight initially. It’s maintenance that is a struggle. People who go on extreme diets will never find success. Lifestyle factors need to be totally addressed. My appetite has completely transformed in recent years. I genuinely thought I would need to get psychological help for my food cravings. But I found that changing how I viewed food ie it’s literally just fuel actually lead to my appetite decreasing naturally. My body adjusted. This artificial tool to reduce weight loss is just not the perfect solution that it is being marketed as. Good luck to everyone on a health journey. But with most things shortcuts are really just longer and more harmful in the long run.

Actually these drugs do not simply suppress appetite. They have very significant metabolic impacts, which is why they are so effective and can improve health so much in well selected patients.

@BunfightBettythis is what the MHRA has carefully considered after looking at all the data presented. The decision made was that the benefits outweigh the possible risks of side effects for people with a BMI of 30 plus, or 27plus with a weight related health condition or 27 plus for certain ethnicities. That process has already been gone through and considered. The MHRA did not feel that more data was needed - were they very wrong about that?

We won't know if they were wrong about that for some time, will we! We'll just have to see what happens over time.

They approved it for those with a high BMI, but people of lower BMIs are taking them, without having the risk profile of those with a higher BMI. That's the biggest concern.

I have no skin in this game, I don't take them and don't plan to. I do worry that some people who don't need them may be taking them without thinking carefully about the downsides.

I agree - admittedly I don’t need wli but I have been very overweight in the past and would have probably snapped them up at the time - early to mid twenties I fried every fad diet, pharmacy only shakes, everything (heartbreak diet solved the issue in the end haha) BUT I do think they are poorly regulated/controlled…… people are injecting insulin when they are not diabetic! That’s so dangerous! (I work in healthcare and have seen devastating effects and death from incorrect insulin management for people that actually are diabetic). Then again, I smoke and ecig and I’m sure in years to come there will be consequences with that.

Sorry, but it’s very worrying that you ‘work in healthcare’ and think that these drugs are ‘insulin’ and that ‘people on them are injecting insulin’.
They are not insulin; they are a completely different drug.

They’ve been around for more than ten years for weight loss specifically already

And more than 20 years of data in diabetes.

it doesn’t mean we know everything about GLP1s, but then again we still don’t totally understand paracetamol. We will learn more, positive and negative, and adjust use accordingly but they are currently being studied for heart, kidney, liver and brain diseases, so usage likely to increase. Injectables might decrease as more effective non-injectable versions become available, but GLP1s are likely to be very commonly prescribed over the next decade.

Mounjaro stops me drinking as much. Terrible!

SilenceInside · 03/01/2026 00:45

@Worralorra there’s no mention of studies in the quote you’ve repeated from the OPs post. Just speculation and repetition of already known issues around weight loss itself.

ThoseWeirdStones · 03/01/2026 00:40

I think this topic generates intense agitation and defensiveness.

I don't have a horse in this particular race, but I hope that it all works out well and people benefit from it.

But I do think there's a rather aggressive push against any measured, cautionary discussion. It seems to cause havoc if criticised or if someone has a negative experience after taking the jabs.
It might be wiser to have a more balanced, nuanced take on such things. We can explore all angles without having to fight.

An emotive subject though. A guaranteed MN page turner for sure:)

Personally, I'd want more data than that over a longer time-span, to make it worthwhile to me. But I'm only a little overweight and could reasonably lose it, if I could be arsed, just by watching what I eat. If I was seriously obese, with all the health implications that brings, I might feel differently and that it was worth the possible future risk to mitigate the risks I was facing now.

BunfightBetty · 03/01/2026 00:33

SilenceInside · 03/01/2026 00:10

Unless you are very short, being a stone overweight would not make you obese. So you would not be eligible for prescription only obesity medication. So, essentially you are saying that you shouldn’t take a prescription only medicaiton for a condition that you don’t have. I think that most people would agree with that!

Are there any other medications, ,
@BunfightBettythat you would advise people not to take for 10 to 30 years just in case of as yet unknown side effects?

I didn't say I wouldn't advise anyone to take it, did I?

As with any medication, there will be side effects and risks. So you need to be sure you have very good reason to be taking it.

Taking something you have no idea of the long term effects of is silly if the benefits for you personally are not great enough to outweigh the potential risks. So for WLI, if somebody is morbidly obese, with type 2 diabetes, high risk for cardiac disease etc, then it's possible to make a case that the benefits of WLI in mitigating these risks are so significant it's worth the potential risks, including those risks we don't know of yet because there isn't the long-term data yet. But if it's just for cosmetic reasons or perceived as easier than dieting without medication, that trade off looks very different.

Personally, I'm wary of taking anything with wide-spread effects across multiple body systems without there being a good and long track-record of data to see what happens to users over time. But it ultimately comes down to need and the individual risk/benefit calculation for each person and condition.

@Worralorra what are these studies that you’ve mentioned in your post?

The ones that OP has mentioned the Doctors are worried about!

”Her doctor admitted that there was widespread concern in the medical field that people who were buying it privately for cosmetic reasons not for medical reasons could face some consequences in the future such as muscle growth and bone degeneration and lack of nutrition - they simply don't have this data at present.”

I’m at the sharp end of this, as a close relative, who I am carer for, is undergoing this treatment, so we have sat through many discussions in appointments where these concerns were raised by DRel and answered in similar vein by their Diabetes specialist consultants…

Pedallleur · 03/01/2026 00:30

The genie is out of the bottle and there is £££ to be made so the chemistry will evolve. All the caveats will apply but for years people have been told of an obesity crisis threatening to bring down the NHS. Now there is an alternative we have a wli crisis. Before we ban the injections let's look at the food industry with it's palm oil, sugar and upf and the responsibilities. Then there was the fat shaming and the smug slims who now seem upset because it's not about them

Buffypaws · 03/01/2026 00:29

BunfightBetty · 03/01/2026 00:04

I don't know about it being the beginning of the end, but it's unarguable that we don't yet have the long-term data on them to really be sure of longer term side effects, and the downsides these may have. We'll only know that after 10, 20, 30 years of them being in use. One good reason to only use them if you are significantly overweight and running the risk of serious health issues like type 2, diabetes, not just if you need to lose a stone or so.

@Worralorra what are these studies that you’ve mentioned in your post?

Worralorra · 03/01/2026 00:17

Mounjaro is designed to help with T2 Diabetes, and the weight loss is a secondary side effect, which also helps if the patient is overweight (although this isn’t always the case).
It can replace some other medications such as fast-acting insulin, which itself can cause issues such as hypoglycaemia (very dangerous) and weight gain (thus exacerbating the Diabetes) and the outlook for using Mounjaro is therefore expected to be better for T2 Diabetics.
As with all weight loss aids, trying to lose weight rapidly can lead to all sorts of the problems that are being reported, as studies have shown that many people using GLP1 are not eating enough of the nutrients that they need, in their quest to get thin quickly, and this aspect is what is concerning Doctors.
If you use weightloss injections, lose weight slowly (about 500g per week), keep doing weight-bearing exercise, eat the correct amount of protein, carbs and sugars for your current weight, and most importantly, don’t increase the dose until your weight loss on your current dose “plateau’s”, you should be OK…

It is very hard to look at size of clothing and decide whether someone is obese. I am technically overweight as my BMI is 25.5, but I am very muscular and was told by a qualified nutritionist and dietician that I should just work on my fitness and not get obsessed about the scales. I am a 12/14, as I have a broad shoulders and narrow hips with very long legs. I am also busty so even when I was younger and thinner I was always a size 12/14 as my shoulders/chest don’t fit into a size 10.

With regards WLI I think people should take it if they need it and it is prescribed to them. Lying to get it and using it is a bad idea and will only end in tears eventually.

Build definitely comes into it. I am a small build so look chubby until I am about BMI 21/22. The more weights I lift then I can be a bit heavier and look slimmer. What i was saying is that someone cant say a size 14 isnt obese, it probably is if you're under 5ft2.

Pear shaped people often weigh more but dont carry fat round their organs which can make them healthier, hence why BMI isnt the only thing doctors look at now. In some countries the WLI will be prescribed to people under a certain BMI if all their weight is round their middle as its so unhealthy.

Bungler · 03/01/2026 00:12

The service I use requires you to complete a live timed and location recorded photoshoot front and side wearing very tight clothes as well as a photo of your feet on the scales, combined with info about height and other medication. It is just not possible to "bulk" up your clothes to appear fatter to get through to a prescription here. I've done two more photoshoots with the same company. I'm now healthy bmi weight and am very much smaller but they know it's definitely me each time. Very happy to use this service, nice and robust though it is quite dangerous balancing on pile of books on a chair to fit into their app's photo frame with feet and arms pointing in the required direction.

People seem to forget that. To be obese at my height (5ft 4) I have to be 2 stone over a healthy weight, that would be a 14-16 also. Just because I'm short doesnt mean it's not unhealthy to be over 30 BMI just because its not 5 or 6 stone to lose.

I am now BMI 25 but my waist measurement is still more 3 inches over a healthy size for my height, something the medical profession is taking as seriously as BMI now. People have lost sight of a healthy looking weight now for sure.

I didn't say I was thin. I said I don't think I am obese.

Obese is the highest weight range possible

A size 14 is not obese. Should I be in the same category as someone who is 28 stone?

The size of your clothing doesn’t decide obesity. Obesity is dependent on your height and weight. So if you are 5ft 3” and weigh anything which puts your BMI above 30 you are obese. Doesn’t matter if you fit into size 12 or a 16.

God this is frustrating.

You say OP’s opinion is ill informed but her entire point is that issues are starting to come to the fore that could potentially create long term health concerns for users and this should be discussed. How is that ill informed? Why are users so blind to the idea that 10, 20 years down the line people might wish they’d never taken WLI because the loss of muscle mass means they’re now wizened 60somethings? And no, I am not saying for a second that will happen, but why aren’t we allowed to debate the possibility?

Muscle loss is a well known issue with weight loss which can be mitigated so i don’t see how it’s a particular concern with this drug. Not sure the trials suggest a particularly rapid or massive loss either, I certainly didn’t have this. As PP mentioned, onus is on user to exercise and lose at a safe pace.

if you lose six stone and then spend 20 years bed bound and get muscle wastage that’s on you not the injections. Everyone knows how to build muscle.

SaySomethingMan · 02/01/2026 23:46

None of what you’ve put in your OP is new info. I’ve seen those points discussed on here several times.

People have just weighed these against the benefits to them and decided to go with the benefits.
