Diverticulosis Is Irritable Bowel Syndrome And Diverticulosis The Same Thing?

Is irritable bowel syndrome and diverticulosis the same thing? - diverticulosis

I was diagnosed with diverticulosis, after a colonoscopy. Symptoms include chronic constipation with swelling. I see that the symptoms of irritable bowel syndrome are similar. I wonder if there are two different names for the same problem?
