Firstly thanks so much for all the advice I've got here so far, I don't know what I'd do without it.
My dad (82) has been eating and drinking less and less for months (just saying he has zero appetite and can't manage any of the food, drinks, and meal replacement shakes we put in front of him), is down to about 57Kg (he's 6ft 1), things came to a head last Friday when he got dehydration and was admitted to hospital. The doctor in A&E asked me why I'd brought him in and I explained about the dehydration, but also said I don't want him to leave hospital until he's got either a diagnosis, or an admission that they don't know what he has (call it 'old age'). They will be doing some CT scans and an echocardiogram this week (he's had these planned as outpatient appointments, but had kept cancelling because he didn't feel up to going to hospital).
The doctor at A&E was very understanding and encouraging, and said he wouldn't leave until then, and also until a care plan was in place for home care, and that they would make the referrals.
In the worst case that they are unable to diagnose anything treatable, is it likely they will refer my dad for home hospice care? As I understand it, this requires a terminal diagnosis, but if they can't diagnose anything can they still refer him to this (since it's evident he's slowly starving and he's not going to start eating enough or accept being force fed)?
This is extremely harrowing for me and my family, watching a loved one slowly starve. I thought most elderly people died of a heart attack or stroke, not of starvation or dehydration - I feel it's mine and my mothers fault for not pushing him harder to eat and drink more these past months, we just brought him all the things he's always liked, and the easy to swallow fortisip drinks, nagged him a bit to try and finish, but accepted and took them away when he said he didn't want more.
