My dad had a stent fitted Friday, he had a week of barely taking anything in and was put on a drip. Following the stent, the food the hospital gave him was awful and just made him feel sick and that's if they remembered. I have managed to get him to have a M and S mini meal, and a few sips. He has taken himself to bed, and is now sleeping. He keeps waking and is complaining of being cold, he has lost alot of weight so wondering if this is it. I don't want him to go back to hospital again. He looks gaunt around the face and red under the eyes (not sure if he has been crying). I feel like he has given up. He seems broken. He has shakes but barely taking them. When do I become worried? What should I be looking out for? I'm completely on my own with this, no real advice or support no nurses coming in.
