Bowel movements are too frequent. Should I be concerned?

Long time sufferer of IBS-D, but drastically improved my diet and supplement stack and not experiencing diarrhea as frequently anymore. But there is one thing. I am still having 4 or more bowel movements a day, all solid, but this is still too much. It’s weird because this doesn’t really fall under IBS-D or IBS-C but it’s still a problem. Thoughts?
