Kidney problems  My shitlord fiance has only one working kidney. The other is just there. If he became obese, it'd probably fuck him up pretty bad. But since he's healthy, all he worries about are the occasional kidney stones (which, to be honest, isn't even a big deal right now). So losing weight would almost definitely help her kidney issues.  fibrocystic breasts  I have ovarian cysts. Not a big deal right now, but it could become an issue should I ever gain a bunch of weight..   nerve problems  Reynauld's syndrom sufferer here, and former dancer. If the dance didn't kill a bunch of feeling in my feet, the lack of proper circulation would. Not an issue since I'm not obese. Healthy veins and arteries for a healthy body.   high blood pressure  The higher your weight, the higher the blood pressure. This isn't always 100% the case, but it certainly plays a major part in it 99% of the time. Obesity doesn't help.   severe hormone imbalance  Hmmm, I wonder what could help that. Maybe...losing weight?  it's a hell of a fight  How exactly is she fighting? By being obese, she's pretty much giving the metaphorical enemy her guns and planting a giant red X on her forehead here. That's not a fight, it's a massacre, and the victim here is her body. She's slowly killing herself, and if she can't own up to the fact that it is indeed her own damn fault, she's gonna lose.
