Hi - I'm new to the forum. Some backgound -

• My dad is living with bowel cancer which has metastasised (has been for a few years now)
• He's on a regular chemo plan (once every two weeks and leaves with a pump) as main treatment - all as an outpatient 
• He's had to be quite sedentary for a few months whilst a cut on his heel which got infected improved - so he's lost a lot of muscle mass / energy from being sedentary 
• He's recently had to start getting regular magnesium infusions which is giving a lot of undesirable side effects (as far as I understand it - nausea, vomiting, diarrohoea etc)
• He had to have a blood tranfusion the other week

He's recently been feeling really unwell from the side effects of chemo and wider medications recently - so his oncologist paused a treatment round to give his body a chance to rest and recover. Within these two weeks, he's started having more pain (seems like nerve pain) as well as being generally uncomfortable and how now been prescribed codeine to help manage this.  

I saw him yesterday and he looks the most sick I've ever seen him. He doesn't seem to be eating or drinking much water so his stomach was really bloated / distended. He's lost the energy to get out of bed / get off the sofa without physical help from my mum. He also seems to have more anxiety than he used to (e.g. panic attack over losing breath moving from sofa to bed) and general indicators of depression. 

They both seem a bit apprehensive about when they should be managing these symptons at home vs going into the hospital. He had a phone consultation with the oncologist last week which resulted in the codeine prescription but they said the consult felt rushed and the doctor was focused on the cancer markers as opposed to his current symptoms.

They have an in person oncologist appointment tomorrow - should I encourage them to get him admitted into hospital before then? I wonder if he needs a few days on an IV drip for hydrationa and a hospital monitoring his eating and bloating more closely.
