Would Finasteride/Propecia cause bowel issues like irritable bowel syndrome, gas, constipation, diarrhea, narrow stool?

I started taking Finasteride 1mg about 10 months ago & have had no side effects (age 25), but a month ago noticed narrow poop, burping, mix of diarrhea/constipation etc. I went doctors and had blood & stool tests done to rule out other conditions, which all came back normal and doc is not says its fine and says its probably irritable bowel syndrome. I was just wondering if Finasteride could cause these symptoms? I’m sure it is something else as I cannot find any other people mention it.
