A DSer on a FB group very kindly granted permission to post this VERY important cautionary tale about what can (probably WILL) happen to a noncompliant DSer. This is not the author's story, but that of a family member. "(A family member) had this surgery about 16 years ago. he wasn't good about keeping up with information and never supplemented properly. His laundry list of health issues is so long, he's lucky to be alive. He developed osteoporosis at about five years i...n, which was detected when he had a seizure and broke his back the first time. The osteoporosis in his spine is so bad now, that he's had several back surgeries and broken his spine multiple times. He now has a permanent pain pump implanted, and is stooped very badly and has to use a walker. His endocrinologist said that my dad had the lowest levels of D he'd ever seen. They were almost negligible. He's also dealt with leg weeping and sores due to low blood albumin (too little protein), and low blood salt, among other things. I'm sure he's deficient in just about everything. Honestly, he's very lucky to be alive at this point, and one bad fall could kill him. He's better about supplementing calcium and vitamin D now, but that's about it. He still doesn't take care of himself well. That's my cautionary tale to everyone. This surgery WILL ruin your life and possibly kill you if you do not take/eat what you are supposed to, no ifs, ands or buts."
