Top question - has she seen any medical profesional? She needs to. Perhaps she can just mention it as part of her normal physical (if she has annual physicals)? Just to make sure something's not making her hormones go berserk. If she's genetically predisposed to that size, she'll have to take some measures to prevent pain later in her life.
I would strongly urge her to invest the extra money in a few really good, supportive bras and to get new ones when the old ones wear out (say, twice a year). Wide, cushioned straps will be a plus. There are companies that will special-fit foundation garments for your girlfriend. She's not going to be able to buy much off-the-shelf, given her size. You might check to see if there's a custom-fit place locally. It's been a while since I've been shopping, but Sears used to have a line of "woman" plus sized bras - she might find one there although I kind of doubt it. You might want to warn her that they're gonna look like "granny" bras, as that's kind of how it goes. Lace and frills in the larger sizes are not something she'll find at Sears. Actually, though, at that size, if it is an option, I'd advise her to go with professionally made and fitted garments.
I've had friends who have had similar problems, from about the same age, who ignored them and now have disc and almost constant nerve problems in their backs from the extra weight. I've also got at least one acquaintaince who did go the "professionally fitted support" route, who has no significant problems.
My daughter has a friend with a similar problem as your girlfriend,and from about age 15, and they are looking into reduction surgery, as even the insurance company considers it a disabling condition. Can't run, can't really walk fast, any jolt (going over a pothole while riding in the car, etc.) hurts her, she has constant back pain, limited positions in which to rest, hormone cycles wreaking pain/havoc with her every month, and on. I don' t know that your friend would want to go that route if she's ever planning to have children, as her ability to nurse could be compromised, but it's always an option.
Nice of you to check for her.
