There are many dangers that can occur with an eating disorder. Some are obvious, but many are not easily detectable without a thorough physical exam, including blood work and consultation with a physician experienced in treating eating disorders. In addition, while a person may feel reasonably well and even have good blood work that recently came back from a doctor, things can turn on a dime. It's important not to assume because a person feels well or can't point to a list of ongoing symptoms, that they are not in any danger.
