HGH doctors are actually endocrinologists. They are also known as internal medicine experts. Endocrinologists specialize in the study of endocrine glands in the body that produce hormones. They are the best persons to understand the function of the pituitary gland, production of HGH and any abnormalities related to HGH. Endocrinologists estimate the height of a child. They also examine child's growth chart for any abnormalities. Some children grow at a slower pace. If the child lacks growth doctor may prescribe HGH treatment.
Once medical tests confirm any deficiency of HGH then hormone replacement therapy is recommended by the HGH doctors which are given by injection. HGH regulates metabolism, blood sugar levels, muscle strength, emotion health and levels of energy. The typical signs of aging that correlate with symptoms of HGH deficiency are increased body fat, muscle loss, weakness, reducing levels of energy and mental status. This has led to the investigation of HGH therapy for illnesses related to age and anti-aging too.
Some HGH doctors have also tried to tackle the problem of HGH by providing hormone replacement therapy without injection. Dietary supplements are available in the market that stimulates pituitary gland to produce more natural HGH, but scientific evidences do not support this HGH therapy for anti-aging. Most physicians recommend prescription therapies. Growth hormone supplementation has been clinically proven to keep people younger. HGH therapy has shown beneficial effect on cardiac and renal functions, thyroid hormone and bone metabolism, sweat secretion and psychological well being.
