Energy availability warning signs

Low energy availability is the one nutrition problem that quietly breaks bones. This screen asks about the body's downstream signals (injuries, digestion, and the menstrual cycle) because they show up before anyone thinks to count calories.

A screening aid, not a diagnosis. Some questions are about periods, digestion, and eating. You can stop at any time, and nothing you choose is saved or sent. If the screen notices a pattern, it will not score you; it will show you who to talk to.
