Answer 4

energy availability, menstrual function, and bone mineral density
-the amenorrhea is a result of low energy availability and is not due to some other medical condition or contraceptive technique that may result in absent menstruation. This type of amenorrhea is known as functional hypothalamic amenorrhea.
-Low energy availability results in chronic undernutrition, depriving the body of the nutrients needed for proper bone development and maintenance. Among the nutrients that may be deficient are those closely associated with bone health—protein, calcium, and vitamin D. Amenorrhea is associated with estrogen deficiency. One of the actions of estrogen is protection against calcium loss from bone, and a low estrogen concentration results in loss of bone calcium and alterations in bone microarchitecture.
