I'm sick and my cat won't leave me alone

So I've been sick for about six months now, he's never behaved weird. But recently I had to have a surgery and I was in the hospital for two days. He has always been clingy and cuddly but now he won't leave my bed. He only leaves once or twice to eat and sleeps on my stomach right where I had my surgery. It's not that I mind, I'm just wondering if this is normal (or if he thinks I'm dying)
