Endocrine disorders are often quite complex, involving a mixed picture of hyposecretion and hypersecretion because of the feedback mechanisms involved in the endocrine system. For example, most forms of hyperthyroidism are associated with an excess of thyroid hormone and a low level of thyroid stimulating hormone. [2]
Endocrinology (from endocrine + -ology) is a branch of biology and medicine dealing with the endocrine system, its diseases, and its specific secretions known as hormones.It is also concerned with the integration of developmental events proliferation, growth, and differentiation, and the psychological or behavioral activities of metabolism, growth and development, tissue function, sleep ...
Estrogen also plays very important role in animal metabolism balance. These unexpected diseases hindered estrogen to get involved in neurodegenerative disease therapy. So, when applying estrogen-like drugs to relieve neurodegenerative diseases, the concentration should be restrictly controlled to avoid these side effects. [citation needed]
Experimental treatments using growth hormone and luteinizing hormone-releasing hormone analogs have shown some success in increasing average height gains by approximately 7.3 cm. Most children with CAH have normal neuropsychological development, although there may be differences in gendered play activities influenced by prenatal sex steroid ...
Signs of hyperestrogenism may include heightened levels of one or more of the estrogen sex hormones (usually estradiol and/or estrone), lowered levels of follicle-stimulating hormone and/or luteinizing hormone (due to suppression of the hypothalamic–pituitary–gonadal axis by estrogen), and lowered levels of androgens such as testosterone (generally only relevant to males).

Estrogen deficiency is also associated with an increased risk of cardiovascular disease, [1] and has been linked to diseases like urinary tract infections [2] and osteoporosis. In women, low levels of estrogen may cause symptoms such as hot flashes , sleeping disturbances , decreased bone health , [ 3 ] and changes in the genitourinary system .
Screening for thyroid disease in patients without symptoms is a debated topic although commonly practiced in the United States. [8] If dysfunction of the thyroid is suspected, laboratory tests can help support or rule out thyroid disease. Initial blood tests often include thyroid-stimulating hormone (TSH) and free thyroxine (T4). [9]
Diagnosis involves blood tests to measure growth hormone levels. [2] Treatment is by growth hormone replacement using synthetic human growth hormone. [1] The frequency of the condition is unclear. [2] Most cases are initially noticed in children. [1] The genetic forms of this disease are estimated to affect about 1 in 7,000 people. [3]
