To think she’s obviously lying

[Friendofafirend]

I have a friend who struggles with their mental health (eupd) I support and love her a lot however I feel she makes her risk seem higher to validate herself. Eg she is saying she hasn’t had anything to drink for two days but when we were out today she came to the loo with me so obviously still is passing urine which you wouldn’t be if you weren’t taking fluids

Did she drink while she was out with you?

You may well still urinate after not drinking for 2 days but it would just be very concentrated.

If she's eaten in the past two days food also contains fluid...

That would normally imply that they haven’t drank alcohol for two days….

When my nan was dying she stopped drinking 5 days before she passed. She was producing urine until the end.

Humans are 70% water you can keep pushing out fluid long after stopping intake. It's not 1 in 1 out.

No she means actual liquid and no food either for two days

Not I don't think that means she is lying at all. However, I would frankly not have the patience for someone who had a condition but made it more difficult for themselves by not doing something as simple as drinking water. I realise I probably sound not very nice, but there is a limit to how much anyone can be helped if they won't help themselves.

I’ve just had an awful weekend of being unwell. Didn’t eat for 3 days and barely drank water. I still passed urine.

I agree with the other posters, you can still pass urine, even if you haven’t drank fluids.If your friend is eating, she’ll be getting some fluids from food.Although when she does pass urine, it will concentrated, not clear.

I think the issue here op is that you don't trust what she says due to the epud. This can be difficult as eupd does often affect relationships with others but it's hard to advise as it affects everyone differently. What she is saying could well be accurate and she's possibly telling you because she wants your reassurance that you care about her. To be honest the best thing you can probably do is keep clear boundaries. Only engage with her on the things you're happy to engage with and gently move the conversation on from the rest while still being reliable and consistent and showing you care in other ways. This is part of how her brain works and is something she will always find a bit harder than others so accepting that's a part of your friend is going to be key alongside your personal boundaries. Has she ever had DBT? It's been really helpful for a number of people with eupd that I know so might be worth recommending.

People still wee and poo when they’re not eating and drinking.

I worked in palliative care, I saw many people who hadn’t eaten/drunk for a week plus.

It’s still possible to wee even if you haven’t had any drink in two days. Your body continuously produces urine as it filters waste and excess fluids from your blood, regardless of your fluid intake. The amount of wee might be reduced, and it could become more concentrated. Dehydration or reduced drinking can slow down how often you need to wee but doesn’t stop the process altogether.

You would still pass urine if you didn’t drink for two days. Whilst she may or may not be telling the truth, she doesn’t need a judgement and ignorant friend.

If she is struggling with her mental health, confides in you, then you come on mumsnet declaring you think she is lying, you aren’t really her friend.

My DM has been seriously ill for 5 days, didn't drink or eat and still passed urine.

Why is she telling you? Seeking advice or just attention?
What's she expecting you to do if anything? Agree with @InSpainTheRain if this is atypical of her behaviour and you're just being used as a dumping ground for her thoughts and feelings
