I saw this and had the same reaction. You don't get lipoedema in your face, neck, forearms, etc. Check out the social media of other "lipodema warriors" and you'll see that, while they may have a certain amount of diseased fat, many of them clearly have a lot more of the other stuff they could lose with the usual methods.
GLP1s have been around long enough where doctors have found there's a hard limit as to how much a patient will lose. Glitter has lost about 20% of her body weight with them which is fairly typical. It's not enough to make a fat person slim but it will improve metabolic function to where T2 diabetes will disappear along with other obesity-related illnesses.
Bottom line, this is liposuction in lieu of diet and exercise, that she, like any narcissist, has to pathologize into "lipodema treatment."
My guess is that she has platinum-level insurance (wealthy parents) and the docs are telling her what she wants to hear to justify a series of surgeries and aftercare that will net them an easy mid-6 figures in fees. My parents are ill (not fat) and are well-covered (though not rich) and I've watched doctors divert them into expensive tests and procedures that turn out to be unnecessary when I press the point.
