Growth Problems in Children
A growth problem means that a child falls either below or above the
average range of growth for a child's age, sex, family history, or racial
Growth disorders can have many
causes. Causes usually fall into one of the following groups:
Familial short stature. This means a
child's height is part of their family's pattern of inherited short height.
Familial tall stature. This means a
child's height is part of their family's pattern of inherited tall height.
Constitutional delay of growth and
This means a child tends to be shorter than average
and enters puberty later than average, while growing at a normal rate. This may be
inherited. These children tend to catch up in time and reach their normal adult
Illnesses that affect the whole body
This includes ongoing malnutrition, digestive tract
diseases, kidney disease, heart disease, lung disease, diabetes, or chronic severe
stress. Any of these conditions can cause growth problems.
Endocrine (hormone) diseases. Growth
can be affected by some conditions that disrupt hormones. Thyroid hormone
is essential for normal bone growth. The pituitary gland at the base of the brain
secretes several hormones, including growth hormone. Growth hormone deficiency can
result from injuries to the pituitary gland or brain. Cushing syndrome can
impair height and cause weight gain. Precocious puberty is a condition caused by
hormone problems. It often causes fast growth and tall height compared with other
children of the same age. But growth stops at an early age. As a result, children
with precocious puberty may be short as adults.
Gigantism. Children will grow faster
than normal if their pituitary gland makes too much growth hormone.
Genetic disorders. This includes
Turner syndrome, Down syndrome, and achondroplasia. Turner syndrome happens when
having too many, too few, or disrupted chromosomes results in health problems. It
caused by one missing X chromosome. This genetic disorder occurs only in girls. It
causes poor growth and delayed or no puberty. Down syndrome is another common genetic
disorder causing poor growth and short stature. It results from an extra 21st
chromosome. Achondroplasia is the most common type of dwarfism, resulting in a
problem changing cartilage to bone. It causes a child’s arms and legs to be short.
also causes a large head and other features.
Many disorders that can cause
growth problems are idiopathic. This means their cause may not be fully known or

between ages 2 and 4, less than about 2 inches (5 cm) between ages 4 and 6, and a
growth of less than 1.6 inches (4 cm) for boys and less than 1.8 inches (4.5 cm) for
