Girlfriend (25F) has PCOD and isn’t taking her health seriously, how do I M25 approach this?

My girlfriend (25F) has PCOD and has been steadily gaining weight. I’m genuinely concerned about her health, not just how she looks, but the long-term risks that come with it.

The problem is, every time I try to bring it up, she either brushes it off or gets irritated. I get why, it’s a sensitive topic, but at the same time, I don’t want to just stay silent and watch things get worse.

I’m not trying to shame her or control her life. I just want her to take her health seriously, especially with PCOD in the picture. I’ve tried being direct, I’ve tried being gentle… neither seems to work.

How do you even approach something like this without coming across as judgmental or making things worse? Has anyone been in a similar situation?
