What exactly happens to the body during a growth spurt?
In: 5
Growth spurts are periods of rapid growth.
A part of your brain called the hypothalamus sends out pulses of hormones which triggers a cascade of effects. It signals the body to produce more sex hormones which results to sexual maturity and secondary changes such as development of breasts, start of ovulation and menstruation, or developing of the testes in males. It also sends signals to bones to grow longer faster. Since all these require energy, it also signals the body to start looking for sources of energy. The body dissolves fat to grow more muscles, and bones. It also triggers other hormones that will make you feel hungry and eat more to get more energy to supply this rapid growth.
