Does haviing Lupus help persuade insurance?
I have UCTD (undifferentiated connective tissue disease) (new doctor gave a new name to my old lupus because he's not convinced). I'm just working on the process, so I don't really know the answer to your question but my guess is lupus will not persuade the insurance company. While things such as joint pains due to lupus would be easier to manage with less weight, lupus is not a co-morbidity of obesity.
Then again, I'm prone to plantar faciitis. Had surgery on my left foot in 2004 and the right foot has now been acting up for about 6-8 months. Plantar faciitis is a connective tissue disease that overweight people get (okay, not just overweight people, but it's more common).
Sorry, I probably didn't answer your question the way you would have liked. Make sure you get your rheumatologist approval for WLS, even though lupus isn't a co-morbidity, I'm sure he/she will be willing to write a letter indicating ways that weight loss will help make your lupus more manageable.
