Growth hormone is secreted by pituitary gland. Growth hormone is responsible for physical growth, specially height growth in childhood and adolescence. With it’s effects on height, growth hormone also controls metabolism of carbohydrates, proteins, fat, bone and muscle. Imbalance in growth hormone causes height disorders and metabolic problems.
Low growth hormone results in short height. Low growth hormone is usually caused by hypofunctional pituitary gland. Deficiency of growth hormones can be at times associated with low levels of other pituitary hormones as well i.e. deficiency of TSH/ACTH/ADH/LH/FSH hormones. Rarely growth hormone deficiency is caused by brain tumors.
Excess growth hormone causes tall height, thick fingers / toes, fleshy nose and lips, increased sweating, hypertension, diabetes, nerve compression etc. high levels of growth hormone is usually secreted by pituitary tumor.
Any person with suspected growth hormone disorder should consult an endocrinologist. Growth hormone deficiency if diagnosed and treated early, has excellent results. People with pituitary tumor secreting growth hormone are generally managed with surgery and medical therapy.
