what is growth hormone?
Growth hormone is a peptide hormone that aids in stimulating growth, cell reproduction and cell regeneration in human. It is also called somatotropin and human growth hormone (HGH). The growth hormone is synthesized, stored and secreted by the somatotropic cells of the pituitary gland. Growth hormone also serves as a stress hormone and raises the volume of glucose and free fatty acids.
Due to certain factors the growth hormone levels get disturbed. The abnormal levels of human growth hormone (HGH) cause varied health conditions.
high levels of growth hormone
The main cause of elevated growth hormone is pituitary tumour composed of the somatotropic cells. These tumours are benign and grow slowly and overtime keep producing excess human growth hormone. The excess human growth hormone (HGH) can result in gigantism, acromegaly, headaches, impaired vision and can result in the deficiency of pituitary hormone.
growth hormone deficiency
Growth hormone deficiency is mainly caused by alterations in the somatomedin. It can result in growth failure, short stature and delayed sexual maturity in children. Although this deficiency is a rarity but it can result in weaker bones and osteoporosis.

The common growth hormone deficiency symptom are as follows;
- Shorter stature and chubbier kids

growth hormone deficiency treatment
Growth hormone deficiency treatment mainly involves synthetic growth hormone injections given directly into the fatty tissues. The long term treatment involves being treated with growth hormone until the child reaches puberty.
The growth hormone injection cost ranges in the higher side and can be expensive looking at its need in a long term treatment.

The growth hormone normal range in a healthy Men < 5 ng/mL or < 226 pmol/L
For women the growth hormone normal range is < 10 ng/mL or < 452 pmol/L
For children the growth hormone normal range is 0-20 ng/mL or 0-904 pmol/L
