Can having anorexia cause an unknown spinal fracture?

 It is possible for someone with anorexia nervosa to fracture their spine without knowing it. This can happen because people with anorexia often have low bone density, which means their bones are weaker and more prone to breaking.

In addition, people with anorexia may not feel pain as acutely as other people do, so they may not realize they've fractured their spine until it's too late. This is why it's so important for people with anorexia to seek treatment and get regular checkups from a doctor, especially if they're experiencing any symptoms of low bone density or osteoporosis.
