The girl is suffering from osteopenia.

The osteopenia is a condition, in which the bone mass of the person is significantly reduced. High amount of training and less intake of fats may cause a decrease in the hormone estrogen in young girls. this decrease in the hormone may lead to the irregular periods as well as decrease in bone mass, which eventually causes osteopenia. the osteopenia is a precursor of the osteoporosis, the osteopenia later, if untreated causes a further decrease in bone mass and porous bone (osteoporosis).

Which of the following best summarizes how hormone levels are controlled?
anastassius [24]

Answer:

Option A, Hormones are controlled by a feedback loop; information about a system is sent back to the controller of the system to improve its function.

Explanation:

Negative feedback loop controls the hormone production and release. This is done by eliciting the release of substances till a certain level after which the stop signal is activated thereby preventing further release. By this method,  concentration of hormones in blood is maintained within the narrow range.  

For example – Thyroid hormones is released when the anterior pituitary signals the thyroid. This continues till the hormones in the blood reach the threshold level. Once the threshold level is reached, hypothalamus receives a feedback and then signals anterior pituitary to inhibit further signaling to the thyroid

Hence, option A is correct
