I frequently need to use the bathroom right after eating, especially if I eat anything greasy or cheesy. Usually my stool is very loose and watery and I often have diaharrea.

I have been experiencing these symptoms for quite some time (usually 2-3 times/week). I also find that I need to use the bathroom whenever I feel anxious or worried. I can't go out to dinner anymore because I need to use the restroom right afterwards.

Does this sound like IBS?

Absolutely sounds like IBS. I have had this problem for 14 years now. You will learn tricks to being able to go out and eat like a "normal" person as time goes on. I still have my times that it is just IMPOSSIBLE to go out to eat, but when I think I can get away with it, I will go (make my family happy). It sounds like you have a nervous/ sensitive bowel like me, so when ever you get upset or worried, you will need to use the bathroom. I hope you start to feel better soon.

Exact same for me, and I think I have IBS, but hasn't been diagnosed yet. Its best to see a gastrinologist and get some tests to know for sure. Maybe even get scoped. Never want to run the risk of it being something else, like a polyp etc...
