The hypothalamus is also known as the subthalamus. It is located on the ventral surface of the brain, below the thalamus, and is the higher nerve center that regulates visceral and endocrine activities. The hypothalamus is usually divided into three regions from front to back: the supraoptic region is located above the optic cross and consists of the supraoptic nucleus and the paraventricular nucleus; the nodal region is located in the posterior part of the funiculus; and the papillary region is located in the papillary body. The hypothalamus lies below the inferior hook of the thalamus and forms the inferior wall of the third ventricle, which is poorly demarcated and extends downward to connect with the pituitary stalk. Although the hypothalamus is small in size, it receives many nerve impulses and is therefore the center of the endocrine and nervous systems. They can regulate the function of the anterior pituitary gland, synthesize neuropituitary hormones and control autonomic and vegetative functions. Hypothalamic damage: A series of symptoms caused by hypothalamic damage due to various reasons, mainly endocrine metabolism disorders, accompanied by vegetative nervous system dysfunction syndromes, including sleep, body temperature, eating, sexual dysfunction, uremia, mental abnormality and so on. Dietary precautions for patients with hypothalamic damage: 1. Dairy products should be avoided in the diet: Yogurt, dairy products, sugar and meat are easy to cause skin fever, so dairy products should be avoided in the diet as much as possible. You can eat more lettuce, kelp, salmon (with bones), sardines and so on. 2, should eat less and more meals: eat less and more meals is conducive to the body to regulate body temperature. Drink more water: Drinking more water or fruit juice can also effectively control body temperature. Reduce caffeine and alcohol: Beverages containing caffeine and alcohol will stimulate the secretion of certain hormones and induce skin fever.
