How do you convince your doctors to take weight gain seriously?

Hello Redditors. I had my transplant back in October and every month since then I’ve consistently gone up 10 pounds. I wasn’t skinny by any means before surgery, I was 150 (28f 5’2”). But now I am 190 and approaching 200. I’ve never been this heavy and it’s taking a toll on my mental and physical health. I’ve mentioned this concern to multiple people on my care team multiple times and they always brush it off saying “let’s just monitor it for now and address it later.” How the heck do I make them address it now? I’m concerned this weight is bad for my new kidney. I feel like if this isn’t addressed soon it could lead to some serious side effects
