Hello, Over The Past Few Weeks I've Noticed That I

Hello, over the past few weeks I've noticed that I have been farting a lot, and I sometimes really need to go poop. I'm a smoker and sometimes halfway through a cigarette I really have to poop and when I do go I struggle to let it out.

I also feel the urge to poop at random times throughout the day, sometimes it's doesn't feel like poop more like air built up. I don't know if this is a huge problem but I thought i would ask.
