Some facts about Hypothalamus and its Function



Hypothalamus lies in the brain and is located in the thalamus and above the pituitary gland. It is a part of the brain which contains a number of small nuclei. It has various important functions.    The most important jobs of the hypothalamus are to make the linkage between a nervous system with endocrine through the pituitary gland. It is a part of the limbic system as well.  The brain of all vertebrates consists hypothalamus. In the case of human, it size is as big as that of an almond. Basically, it plays important role in hormone production and contributes in stimulating many important processes in the body. The function of this is very important.  If it does not work properly many kinds of disorder in the body arises and so it is very important that it should work properly to have a low risk of health. Although it is a small area of the brain it plays a big role in the body by producing both in the endocrine and nervous system.

Hypothalamus Functions

In medical terminology, homeostasis refers to the balance state of the body.  Homeostasis state in the body is very important, so the body always tries to keep their state in balance state and to maintain that states it plays a vital role. To maintain body in balance state hypothalamus plays a role of
The connector between endocrine and nervous systems. It plays essential role in functions of the body like

  1. Body temperature   Thirst   3. Appetite and weight 4. Control Emotions 5. Sleep cycles 6. Sex drives Childbirth 7. Blood pressure and heart rate 8.  Production of digestive juices 9. Balancing bodily fluids

In case of unbalance in the body, the hypothalamus releases the right hormones into the bloodstream to create a state of balance in the body. One of the examples is the stability of body temperature of 98.6°F. When hypothalamus receives the indication that the body’s internal temperature is too hot, it tells the body to sweat. If it obtains the indication that the temperature is too cold, the body will generate its own heat by quivering.

Hormones of the hypothalamus

Hypothalamus is accountable for creating or monitoring different hormones in the body. It is also associated with the pituitary gland, which makes and drives other significant hormones around the body.

The hypothalamus and pituitary gland control entire endocrine system, the glands that yield numerous hormones of the body. These are adrenal glands, kidneys, and thyroid. Here is some of the hormones work produced by the hypothalamus are as listed below

Antidiuretic hormone, which monitors the amount water absorbed into the blood by the kidneys

Corticotrophin-releasing hormones which regulate metabolism and immune response working together with the pituitary gland and adrenal gland to release some certain steroids

Gonadotropin-releasing hormones which convey pituitary gland to deliver hormones which keep the sexual organs functioning

Oxytocin which involved in many procedures such as release of a mother’s breast milk, temperature of body and regulating sleeping cycles

Prolactin-controlling hormones command pituitary gland, either start or stop the production breast milk in lactating mommies

Thyrotrophic-releasing hormone work is to activate the thyroid.  these hormones regulate metabolism, energy levels, and age-related growth

Growth hormones are directly influenced by the hypothalamus. It commands the pituitary gland, either increases or decreases their number in the body which is important in case of growing children and developed adults.

Hypothalamus disorders

When hypothalamus does not work properly it is said a hypothalamic disease. It is very difficult to identify since hypothalamus has a wide range of roles in the endocrine system. Again hypothalamus also plays very important role in signaling to the pituitary gland to deliver hormones to the rest of the endocrine system. In this way, it becomes very difficult for a doctor to diagnose which gland isn’t performing properly. This kind of disorder is referring to hypothalamus-pituitary disorders. In this situation, doctors used to suggest for some hormone tests to get the root of disorder

Causes and risk factors

Mostly hypothalamic diseases happen due to the injury to the head. This is because due to head injury there is an impact on the hypothalamus. Surgeries, as well as radiation, could also have an effect in the hypothalamus. Sometimes genetic link could also be the cause of hypothalamic disease. It is said and written in many books that hypothalamic disease may cause

Bulimia or anorexia (eating disorders)

Excess of iron building in the body (Genetic disorders)




Over bleeding

Hypothalamus disorders Symptoms

Symptoms of hypothalamus disorders depend on hormones status in the body.  Children could have abnormal growth and abnormal puberty. Adults may have problems linked with the various hormones their bodies cannot produce. If a person has overactive thyroid gland he could symptoms of

  1. Sensitivity to cold, 2. Depression .3. Tiredness Impotence 5. Hair loss 6. Menstrual cycle changes 7. Constipation 8. Lower mental capacity 9. Weight gain

Diet tips for hypothalamus health

Hypothalamus has a vital role in the body. So it is very important to maintain its health healthy.   However, if someone has an effect due to genetic cause it is very difficult to avoid. To maintain its health there are some diets that can give some relief from it when taken daily.

Research on this has revealed that diets which are high in saturated fats can change the function of it that regulates hunger and energy disbursement. High saturated fats are found in lard, meat, and dairy products. High saturated fatty diets also have inflammatory effect which affects the immune system that makes healthy body cells

A polyunsaturated fatty diet such as omega-3 helps to reverse the inflammation. These types of fats are good option other types of oils and fats. Fish, walnuts, flax seeds, and leafy vegetables which has high omega-3 contains support the hypothalamus and helps the brain to function well.

Vitamin-rich fruits and vegetables

Vitamin C

B vitamins

The Proper hypothalamus is one of the most significant parts of the body. With the help of these diets, it remains happy and working perfectly.
