The hypothalamus is the part of the brain that secretes chemicals in the form of hormones that the body needs to help control organs and cells. The main function of the hypothalamus is homeostasis, which is to ensure and maintain all body systems running stably.
The hypothalamus produces hormones that control the production of hormones in the pituitary gland. The hormones produced have important benefits and maintain various aspects of human health. If the hypothalamus function is disrupted, then the overall hormonal balance in the body will be affected.
Various Functions of the Hypothalamus
Although small in size, but the function of the hypothalamus is very important in controlling bodily functions, such as controlling body temperature, hunger, and thirst. The function of the hypothalamus also plays a role in many processes in the body, including conscious or unconscious behavior, as well as endocrine functions, such as metabolic processes and growth and development. The function of the hypothalamus is also related to the body's ability to control several other things, including:- Heart rate
- Mood
- Sleep quality and quantity
- Sex drive
- The release of hormones from many glands, including the pituitary gland.
The hormone produced by the hypothalamus
Important hormones secreted by the hypothalamus include:Antidiuretic hormone
This hormone functions to regulate the balance of water levels in the body, including blood volume, which in turn affects blood pressure.
Oxytocin
The hormone oxytocin affects the reproductive system such as labor, breastfeeding, and ejaculation. This hormone also controls various human behaviors such as sexual arousal, anxiety, and building emotional bonds between mother and baby in the process of breastfeeding.
Somatostatin
Is a hormone that works in the central nervous system, functions to inhibit and limit the production and work of other hormones, especially growth hormone (GH) and TSH (thyroid-stimulating hormone).
Growth hormone-releasing hormone (GHRH)
This hormone plays a role in growth, including physical development in children and metabolism in adults, by stimulating the release of growth hormone.
Gonadotropin-releasing hormone (GRH)
Work to stimulate the release of hormones associated with reproductive function, puberty, and maturation of the sexual organs.
Corticotropin-releasing hormone, CRH
Control the body's response to physical and emotional stress, and is responsible for suppressing appetite and also triggering anxiety.
Thyrotropin-releasing hormone
This hormone which will stimulate the production of thyroid hormones, to control the body's metabolism, cardiovascular system, brain development, control muscles, and digestive and bone health.
Causes and Symptoms of Impaired Hypothalamic Function
The function of the hypothalamus for the body can be hampered due to the disruption of hypothalamic function which is also known as hypothalamic dysfunction. This condition has various causes. But the most common causes of hypothalamic dysfunction are complications from brain surgery, severe head injuries, brain tumors, and radiation. Other causes of hypothalamic dysfunction are:- Infection and inflammation
- Nutritional health disorders, for example due to eating disorders such as anorexia, or extreme weight loss.
- Genetic disorders, such as Prader-Willi syndrome, Kallmann's syndrome, to diabetes insipidus.
- Blood vessel disorders in the brain, such as aneurysms and subarachnoid hemorrhage.
