Nurse said i need to stop weightLifting with ulcerative coltis

I recently had an acute ulcerative colitis that was pretty bad, I was in the hospital for around 2-3 weeks and I’ve been discharged for about a week and a half now, feeling pretty good and getting back in to exercising like playing basketball and stuff. Today an IBD nurse told me in an educational session that I should not lift weights at all for the rest of my life due to the disease, and that if I want to lift weights I should lift light weights. She didn’t provide any evidence or study though, just told me this without explaining. I’ve seen online the opposite, and that lifting helps with the disease. Is the nurse wrong? any help would be greatly appreciated
