How can a Colonoscopy differentiate between IBS and IBD?

I was diagnosed with IBS more than a decade ago and only applied the lifestyle changes my doctor recommended, never got screened again. My symptoms continue (with no fever, nausea or blood in stool) but I also have unexplained skin rashes, joint pain, upper back aches, etc. Could this have been a misdiagnosis back in the day? Can IBS turn into IBD? Can I get clearer answers with a Colonoscopy?

It can rule out IBD, yes.

You would need a Colonoscopy with biopsies to rule out IBD. No, IBS does not turn into IBD. I would suggest you see a gastroenterologist and discuss your symptoms.

Small number of patients with IBS symptoms are found to have IBD on initial Colonoscopy. You might benefit from repeating Colonoscopy evaluation since it has been a while, and you might be due for respect Colonoscopy for other reasons such as screening purposes. Check with your GI doctor or request to see a GI motility specialist.
