Antidiuretic hormone (also known as vasopressin) is a 9-peptide hormone secreted by nerve cells in the supraoptic and paraventricular nuclei of the hypothalamus and released after reaching the pituitary gland via the hypothalamic-pituitary bundle. Its main role is to improve the water permeability of the distal convoluted tubules and collecting ducts, promote water absorption, and is a key regulatory hormone for urine concentration and dilution. In addition, the hormone also enhances the permeability of the collecting ducts of the inner medulla to urea. After drinking large amounts of water, blood is diluted, crystal osmolarity decreases, and secretion of antidiuretic hormone decreases. What is the dietary care for reduced secretion of antidiuretic hormone (adh)? 1.Limit the water intake, pay attention to the water-electrolyte balance, and pay attention to sodium supplementation. 2. Pay attention to strengthen nutrition, eat more high-protein foods and vitamin foods, such as lean meat, liver, egg yolk, brown rice and green leafy vegetables. 3, eat more food with diuretic effect, such as winter melon, cucumber, loofah, bitter melon, red bean, barley, tomato, leek, white radish, pomegranate, grape, orange, perilla, watermelon, fishy grass, green onion, onion, lemon, etc. SIADH is an abnormal increase in the secretion of antidiuretic hormone (ADH) not regulated by plasma osmolality, resulting in an increase in water retention and sodium excretion in the body. SIADH is a syndrome with a series of clinical manifestations such as water retention, increased urinary sodium excretion, and dilutional hyponatremia. In addition to severe craniocerebral injury, cervical medullary injury, severe intracranial infection and acute phase of cerebrovascular disease (10%-14%), there are also malignant tumors and lung tumors.
