Normal growth is defined as the progression of changes in height, weight, and head circumference that are compatible with established standards for a given population.1
Measured in height, “normal” growth is described as growth of:2
There is minimal difference in growth seen in boys and girls until puberty, which results in an average height difference of 4 inches to 5 inches between the sexes.
Normal growth is influenced by environmental, genetic and hormonal factors. Studies have shown that non-pathological factors such as nutrition, psychological influences, physical activity, and climate play important roles in growth.3
Symptoms of growth hormone deficiency depend on various factors such as the child's age and the cause. Children have poor overall growth rates, usually below 2 inches (5 centimeters) per year, and most have short stature but normal upper and lower body proportions. Some children may have a delay in tooth development or a delay in puberty. Other abnormalities may be present depending on the cause of the growth hormone deficiency. New born with growth hormone deficiency may have low blood sugar (hypoglycemia), jaundice (hyperbilirubinemia), or other congenital abnormalities such as a small penis (micropenis) in males or face defects (such as a cleft palate). Children may also have symptoms of other hormone deficiencies such as central hypothyroidism.5
Although it takes about 3 to 6 months to realize any height differences, the important thing is that your child may grow probably 1 to 2 inches within the first 6 months of starting treatment. There may be a few other things you notice:6
It may take a number of years for your child to reach his or her adult height, so you should be aware that GH treatment is often a long-term commitment
Growth hormone injection is prescribed for children diagnosed with growth hormone (GH) deficiency and other conditions causing short stature8
A number of other tests must be conducted first to confirm GH deficiency, Turner syndrome, or other conditions for which GH therapy is indicated8
GH treatment could be beneficial in the treatment of GH deficiency8
Growth hormone deficiency (GHD) is a journey for children and their families, and we want to make sure that each family gets support at every step.
