Just as a country has a capital city and a provincial district has a provincial capital, the human body has a central command for its endocrine glands, which is the pituitary gland. As there are different branches of government, there is also a completely different division of labor between the anterior and posterior parts of the pituitary gland. The anterior half of the pituitary gland, which becomes the “anterior pituitary or pituitary gland,” is responsible for the secretion of other important endocrine organs throughout the body, such as the thyroid, adrenal and gonadal hormones. The pituitary gland itself is regulated by a higher authority, the DD hypothalamus and the brain, and is directed by the higher authority. For example, during childhood, the pituitary gland constantly receives inhibitory signals from the superior, the pituitary itself does not secrete FSH and LH, and the secretion of sex hormones in children does not increase. When puberty is about to begin, the pituitary gland receives more and more signals of excitement and less and less signals of inhibition, so the secretion of FSH and LH increases and acts on the testes or ovarian tissues, causing them to produce more estrogen and androgen, further promoting pubertal development. The posterior pituitary gland mainly stores DD antidiuretic hormone, a hormone that makes the body urinate less. If the posterior pituitary gland is damaged or if the pituitary stalk is interrupted, this hormone cannot reach and be stored in the posterior pituitary gland, causing a large increase in the body’s urine output, which can be tens of thousands of milliliters per day, with many patients urinating at 1-2 hour intervals and needing to drink and urinate several times at night. Many patients visit the hospital as a result and discover pituitary disease. Structurally speaking, the pituitary gland is located at the base of the skull in the brain and hangs like a light bulb in the pterygoid saddle. The pituitary stalk is like a wire attached to the bulb and connected to the brain. The brain and hypothalamus regulate the action of the pituitary gland through this thin “wire”. If the wire is compressed by trauma or tumor, so that the signals from the hypothalamus and brain cannot be transmitted to the pituitary gland, then endocrine hypofunction and uropathy will occur, manifested as fear of cold, easy to catch a cold, increased urine output, etc. Diseases of the pituitary gland mainly include trauma, inflammation and tumors. Because men are much less likely to develop autoimmune diseases than women, the chance of inflammatory diseases of the pituitary gland is also reduced. In general, babies are often born from their mothers with their heads exposed first. If the baby is born in the wrong position, the feet come out first, which often leads to difficulties in delivering the head, birth injuries or asphyxia, resulting in a break in the “wire” connecting the pituitary gland or damage to the pituitary gland, resulting in a decrease in the secretion of various hormones by the pituitary gland. A decrease in pituitary function can lead to a decrease in thyroid, adrenal and gonadal function and a decrease in growth hormone secretion, resulting in slow height gain, short stature, delayed mental development and other growth disorders. The sooner the deficient hormones are replaced, the better the results will be and the more the damage caused by hormone deficiency can be compensated.
