Responses to weight loss injections?

Since losing nearly 3 stone in weight on weight loss jabs, I have noticed how much better my u/c is? Is the reduction in inflammation down to losing belly fat? I have stopped taking my Humira jabs and I’m med free at the moment, but I’m not sure quite what’s going on? Has anyone else had a similar response?

63 yr female based in UK. U/C since 18 years of age with hospitalizations and severe flare ups during my 50s (menopause?).
