To say something or not?

Mind your own business. There could be many many season.

Well, above my bedroom there's a flat and they've installed an ensuite bathroom. Someone new moved in and started regularly vomiting at 4am, with over the top/exaggerated vomiting moans, followed by lots of "oh my Gods".

I knocked on their door eventually, during the day, and did politely say that, if they weren't aware my bedroom was below and sound carries, and I'm sorry someone has been unwell but to please be aware, the moaning and shouting accompaniment woke me up every time.

It's been quiet ever since.

I'd try knocking as maybe they'd be mortified if others were hearing it. It's possible to vomit without the whole world/next door hearing.

This is a constant problem, people don’t read OPs posts. Some of them barely read the OP. You don’t have to read every single response, but the bare minimum is all of OPs posts.

Read the thread....here we are 3 pages on and the OP stayed she would not say anything about three posts after the start of the thread.
Here everyone is still wittering on.
Including me.
What the hell is Mumsnet for, except talking into a vacuum.

You could absolutely check in on them if it were coming from a place of empathy. But it doesn't sound like that's where youre coming from.

Poor bloke. Don’t say anything and definitely don’t say you think you heard a fox vomiting, what a bonkers suggestion!

I don't think he can do anything about it.
It's not like he is playing loud music or shouting and swearing.
It's something he has no control over.

If you mentioned it this would only cause embarrassment.
I'm assuming he is in the bathroom. Where else could he vomit?

If it was deliberate noise then fair enough, but it's clearly something he can't control. It would be like complaining about a neighbour crying or sneezing.
It sounds like the poor guy has enough to deal with.

I’d say she’s got an excellent point, the poor kids!! Not at all inappropriate

Has it occurred to you he may be ill and having treatment like chemo or radiotherapy? I'm sure he would rather not be vomiting constantly!

Why? Genuinely, why do you think this is true? It’s not.

OP does have to live with it because living with reasonable noise, and bodily functions are absolutely reasonable noise, is what happens when you live in a flat.

It might not be nice to live with, but it’s absurd to just state you shouldn’t have to put up with normal human things just because they’re not particularly nice.

Anyone saying they’d say something was either not raised properly or are just playing the big man for mumsnet. It would be so ridiculously rude to comment on this.

I’d rather have to listen to a vomitty neighbour than have a nobhead next door.

It could be a medical condition, a side effect of medication, or even something completely random. My stepdad vomits pretty much every morning without fail when he brushes his teeth because it sets off his gag reflex.
I honestly wouldn’t say anything. If he’s being sick every morning, I doubt he’s doing it for fun, and it may be something he has absolutely no control over. I think mentioning it would come across as quite intrusive and probably embarrass him as well.

There is nothing to be achieved by saying something. What are they meant to do? stop vomiting? You need to invest in better sound proofing, if you can hear someone vomiting through your wall it is obviously inadequate and needs to be reinforced, the noise could also be coming down your pipes so maybe get a plumber to look at that

He can't just stop vomiting because you don't like it! I'm also emetophobia but I understand this is my problem not anyone else's

How'd you know it's him?

Was going to reply - yes, say something. But upon reflection, you can be more subtle.

He possibly doesn’t know you can hear - but if you can hear him, then he would be able to hear you too? So what I would do is play music or the morning news/BBC [ie conversation] on your iphone in the bathroom at a reasonably high level of volume EVERY time he is sick. He will hear and realise that you can also hear. Hopefully it will mean he stops after a few incidents of you making a point.

Nothing needs to be said, but he may at least do what he does when they have guests (different bathroom?) - or go to his GP.

Unless you're really close friends with them (which you're not) there's no way you can mention this even in a "concerned" way, without looking really nosey and insensitive. The issue really is sound proofing, not what is happening in their home. I don't think there's much you can do, but maybe ear plugs or a snooze band or playing white noise would help or are there spind proofing pads you can put on the wall like you would for a music room. It is likely to be a mental or physical condition that they cannot help, mentioning it will not enable them to do anything about it except for feeling embarrassed and awkward. If it's a flat, I'm assuming there's not much space so unlikely there is "somewhere else" it can happen. Possibly for visitors he hides it by some other method (medication etc) that doesn't work long term or if it's bulimia he can cope covering it up for the night but it won't be something he can "just stop". People don't throw up for fun.
If you absolutely feel you have to say something, I'd be super discrete and say something like "I've been hearing an animal, maybe a fox or cat, sounding ill, just wondered if you'd heard it too" rather than specifically say "your throwing up is really noisy" (I honestly just don't know how you'd be able to say those words to random neighbours tbh, its wildly personal).

Sorry - why were you embarrassed?

I’m stuck on how the OP knows who is vomitting. This must be paper thin and see through walls.

If its Bulimia its not qiite that simple.

What do you think it would acheive?

I'd mention it for the sake of the children, it's not good for them to hear it either.

What do you think will happen to the kids? My children would have not been adversely affected by some vomiting noises. What would it do to yours?

Goodness. Of course you don’t say anything. The problem here is shoddy flat construction and inadequate sound-proofing.

This is so inappropriate it's unreal.

How would you know who is vomiting though? Maybe the mother is pregnant.

Sounds like he may have an eating disorder, but interesting he doesn't do it if there are visitors. I would mention it as if he modifies his behaviour for visitors he would also modify his behaviour if he knows neighbours can hear him. I'd mention it for the sake of the children, it's not good for them to hear it either. I'd definitely mention it and mention you've noticed a pattern when they don't do it with visitors. It could be the trigger he needs to do something about it.
