bone density

hi there cyberdoc. hope you''re having a good weekend!

quick question: if your patient (social long distance runner) is underweight (BMI 15/16) and ammenorrheaic, do you tell her to first gain weight and then go back to running long distance or can she continue running. If she continues, arent you almost increasing her risk of stress fracture...?

The person can continue exercising but will have to increase her total body mass, in order for her menstrual cycle to return. Such a low body weight will have severe negative effects on her body and also restrict her athletic abilities.

A BMI lower than 17.5 may indicate Anorexia Nervosa. Please refer to the following article for detailed information and complications:
