Binge-Eating.
In many cases amenorrhea does not occur. There are many reasons why this could happen. Maybe the body is used to the conditions in which a normal body does not adapt. For example, someone is at an extremely low weight but they have been at the weight for a long time so they get their period. Also people have different weights where they experience amenorrhea. Someone may have lost weight, but not enough to have amenorrhea but enough to get into the range classified as an eating disorder criteria. Also men do not have periods, obviously, so they would not lose what they never have. I hope I have answered your question.
