In brief: Veery rarely
Bleeding and injury to the bowel.
In experienced hands the combined risk is less than 1 %. You may have gas and bloating afterward but these should resolve quickly and you can resume normal activity and diet the next day. The risk of having an undiagnosed colon disease or cancer is greater than the risk of the procedure.

In brief: No
While there are certainly risks to having a colonoscopy (bleeding, injury to the colon wall, or the risks of sedation), these complications are very rare.
As for side effects, not really. The bowel prep may exacerbate hemorrhoid problems, but aside from that the day after a colonoscopy should just be a normal day.
