The teenage years are also called adolescence. During this time, parents will see the greatest amount of growth in height and weight in their child.
Adolescence is a time for growth spurts and puberty changes.
An adolescent may grow several inches in several months followed by a period of very slow growth, then have another growth spurt. There is a great amount of variation in the rate of changes that may occur. Some teenagers may experience these signs of maturity sooner or later than others. Sexual and other physical maturation that occurs during puberty is a result of hormonal changes. This hormone then causes additional effects.
