Signs that a boy's height will rapidly increase

Signs that a boy is experiencing a rapid growth spurt in height typically include leg cramps, increased appetite, and feeling sleepy easily. If the body grows too quickly and nutrition cannot keep up—especially if there's a calcium deficiency—leg cramps may occur. Rapid height growth requires substantial nutrients, leading to a constantly increasing appetite to absorb necessary nourishment. During a growth spurt, the body needs to secrete large amounts of growth hormone, which requires sufficient sleep; hence, the individual often feels tired and drowsy.
