My husband poops CONSTANTLY

Okay... I’m not exaggerating when I say it’s constant. He probably goes poop 5-6 times a day. In the middle of a meal he will have to get up and go poop. He says his stomach doesn’t hurt, there’s no pain, it’s just constant pooping. He will also spend up to 20 minutes in the bathroom. Is this normal? I feel like it’s not. He will eat something and immediately have to poop it out. It’s like he doesn’t even digest his food. Any insight? What is this? It’s gotten worse over time.
