7 Normal variantsFamilial (genetic) short stature and constitutional short stature are common variations of normal.Individuals with familial short stature have a normal growth rate even though it is below the 5th percentileThey do not have skeletal delay, puberty and pubertal growth spurt occur at the usual chronological age, and final height is appropriate for mid-parental target height
8 Normal variantsThose with constitutional short stature have growth deceleration in the first two years of life, with normal growth velocity being achieved by age three and continuing throughout childhoodOnset of puberty is usually delayedAdult height is in the normal range but varies according to parental height
9 Non-endocrine causesNon-endocrine causes of short stature are commoner than endocrine causesPatients with non-endocrine disease tend to have normal body proportionsChronic malnutrition is the commonest cause of poor growth globally :inflammatory bowel disease, coeliac disease, or anorexia nervosaShort stature is also commonly associated with renal disease, and conditions associated with hypoxia or hypoxaemia, such as congenital heart disease, pulmonary disease, and haemoglobinopathiesPsychosocial deprivation often causes short stature. Placing the child in a different environment results in growth catching up.
10 Endocrine causesGrowth hormone deficiency or insufficiency is an uncommon cause of short staturePrevalence of the condition :1 in 4000Classic GH deficiency : short stature, increased fat mass leading to a “chubby” appearance with immature facial, immature high-pitched voice, and delay in skeletal maturation.The calvarium seems to be relatively overgrown (delayed closure of fontanelles), with prominence of the frontal bone
11 Endocrine causesThe impairment of growth in Cushing's syndrome is predominantly the result of a direct effect at the growth plate. The commonest cause is iatrogenic (treatment with glucocorticoids), with endogenous glucocorticoid excess (Cushing's syndrome dependent on the pituitary and adrenal glands) being much rarer.
12 Causes Several factors contribute to short stature, including: Genetic factors (eg, skeletal dysplasias, Turner syndrome, Down’s syndrome, Silver Russell syndrome)Endocrine disorders (eg, hypothyroidism, growth hormone deficiency)Delayed puberty (causes temporary short stature, but normal height is eventually achieved)Early pubertyMalnourishment (on a global scale, this is the most common cause of growth failure and is generally associated with poverty)Chronic diseases:Congenital heart diseaseKidney diseasesAsthmaSickle cell anemiaGastrointestinal disorders (eg, inflammatory bowel disease)Lung conditions ( cystic fibrosis, severe asthma, chronic obstructive pulmonary disease)
