Adrenaline and norepinephrine: hormones, differences, main functions

The stressful situation requires the mobilization of all defense mechanisms from the human body. In this process, hormones are directly involved, among which adrenaline and norepinephrine are in the first place.

What is adrenaline and what is its main difference from norepinephrine? Where are these substances produced and what are they responsible for? Consider these questions in more detail.

Adrenaline and norepinephrine are hormonal elements that belong to the catecholamine group. Despite the fact that these components are closely related to each other, there is a definite difference between them that you need to know about.

Thus, the hormone fear adrenaline is a substance that is synthesized by the body as a response to a stressful situation. Its level increases significantly in the case of a person in a state of shock. This substance is also called epinephrine. Therefore, the difference between the terms epinephrine and adrenaline does not exist.

If adrenaline is a hormone of fear, then what is norepinephrine? Noradrenaline is a kind of precursor to the hormone adrenaline. By a biochemical process, when a stress situation arises, epinephrine is formed from this substance.

But, as already noted, there is a close relationship between these hormonal units. If the hormone adrenaline in the blood of a person is responsible for the feeling of fear, then norepinephrine is responsible for expressing such emotions as rage. And these concepts, as is known, are "related" to each other.

Where are hormones produced?

What produces adrenaline and norepinephrine?

The brain hypothalamus is the first to respond to a stressful situation. It is in his cells that the synthesis takes place and then the release of corticotropin. This substance reaches the kidneys, activating the work of the adrenal glands.

For more information about the stress hormone cortisol, see http: // kortizol.html

If you talk about which body produces adrenaline and noradrenaline, the production of these hormonal units occurs in the medulla adrenal glands. These are paired endocrine glands that are regulated by the brain. But it is not always they who provoke the release of the hormonal elements in question.

So, the precursor of adrenaline and noradrenaline is tyrosine, part of which enters the human body during the consumption of food enriched with protein. During complex biochemical reactions, tyrosine is broken down into various substances, one of which is Dof.

Once in the blood, this element reaches the brain. Subsequently, Dofa becomes an expendable material from which a new hormonal unit is formed - dopamine. And from it, in turn, norepinephrine is formed.

Therefore, if we talk about what norepinephrine is, then we can definitely say that this is a hormone that is synthesized in a series of complex biochemical processes. Together with adrenaline, they create a reliable defense of the body against the effects of stress and shock, which helps prevent adverse and dangerous consequences.

Important! Despite the important role of these hormones, consistently elevated levels of their content in the blood can lead to serious consequences! Adrenaline is a stress hormone, and norepinephrine is a “hormone of rage and courage” under certain circumstances can harm the body, so it is extremely important to stop the pathological abnormality in a timely manner.

Difference between hormones, their main functions

Having understood the elements in question, and knowing which gland produces the hormone adrenaline and norepinephrine, it is necessary to understand what the difference between these elements is. And there are several differences.

So what's the difference?

The differences between noradrenaline and adrenaline are primarily in the impact on the human body of each of these hormonal units.

First of all, we note that a sharp increase in the level of adrenaline in the blood has more severe manifestations, and can cause serious deviations. Its negative effect on the body is manifested by increased irritability, nervousness, aggressiveness. This causes serious harm to the cardiovascular system.

One can often hear the question: does adrenaline constrict or dilate the vessels? This substance has vasoconstrictor properties, which are widely used in medical practice. However, excessive narrowing of the blood vessels, as already noted, is fraught with serious health consequences.

Another criterion relating to the question of how adrenaline differs from norepinephrine is the ability to cause euphoria. Epinephrine is a substance that can lead to such a state, but norepinephrine never causes it. Moreover, norepinephrine has a pronounced cosmetic effect, which can not be said about adrenaline. So, under its influence there is a blush on the cheeks, and fine mimic wrinkles are smoothed.

Functions of hormonal elements

How does adrenaline affect the body, what are its main tasks and role? It should be immediately noted that the functional characteristics of this substance and norepinephrine are similar to each other, so there is no need to consider them separately.

So, what are the functions of adrenaline are:

  • narrowing of blood vessels;
  • increased heart rate;
  • accelerated breathing;
  • high blood pressure;
  • tremor in the upper and lower extremities;
  • accelerating intestinal motility.

In addition, the effect of adrenaline and norepinephrine on the body is manifested:

  • delivery to the cells and tissues of the body a large amount of oxygen;
  • increase in blood glucose;
  • acceleration of lipid and protein metabolism.

Therefore, if we talk about what adrenaline is in the blood, we conclude that it is a hormone that protects the human body from the dangerous effects of stress and shock states. However, its overabundance can lead to serious violations, so it is necessary to fight with such a condition!

Analysis of adrenaline, symptoms of its excess and methods of normalization of

If serious disturbances occur in a person's condition, he is prescribed an analysis of the adrenaline content in blood. An endocrinologist, a therapist or a cardiologist may refer a patient to a study. It all depends on what kind of symptoms there are complaints.

The absolute indications for the test include:

  • infarction or preinfarction state;
  • manic-depressive syndrome;
  • presence of tumors prone to rapid growth;
  • diabetes.

For research on noradrenaline and epinephrine, the biomaterial is taken exclusively from a vein. It is better to take blood in the morning - so the test will give more accurate results.

Before the examination, the patient should be thoroughly prepared, following the following rules:

  • 72-86 hours before the test, chocolate, citrus fruits, bananas, coffee should be excluded from the diet;
  • on the day of the study and the day before it is better to refuse to take Aspirin;
  • analysis is postponed to another day if the patient suffered stress before or on the day of the study.

It is also better to give up smoking a few days before taking the biomaterial. Nicotine leads to an intense release of adrenaline and noradrenaline into the bloodstream, which can distort the test data.

Signs of an increase in adrenaline

What symptoms are characteristic of an excess of adrenaline in the human body? This deviation occurs:

  • anxiety;
  • shortness of breath;
  • tachycardia;
  • arrhythmia;
  • with an attack of hypertension;
  • unreasonable bouts of aggression;
  • muscle weakness;
  • hypersensitivity to pain.

With prolonged exposure to adrenaline on the body, there is an overrun of energy, which is released under the influence of glucose. As a result, exhaustion occurs - emotional and physical. The person begins to complain of fatigue and atony of the muscles, he becomes lethargic and apathetic.

Normalization of the level of the hormone

How to increase adrenaline? First of all, remember that you can’t do this on your own by any means - this can lead to serious complications!

You can compensate for the lack of hormonal substances with the help of special medications based on adrenaline. The selection and appointment of the dosage is carried out by the attending physician.

If the hormone deficiency is a consequence of pathological processes occurring in the body, first of all, it is necessary to eliminate the cause of the indisposition. When tumors are prescribed chemotherapy, radiation therapy, or surgery is carried out. Only then, if necessary, the doctor wonders how to increase norepinephrine and adrenaline in the patient's body.

Kidney or nervous system diseases can be treated by conservative methods. In any case, the attending physician selects a suitable therapeutic technique on the basis of the data obtained during the diagnosis.

Increase adrenaline without drugs

How to develop adrenaline yourself without resorting to medication, and is it possible to do it? Yes, it is quite real. And this can be done with the help of:

  • practicing extreme sports: skydiving, car racing, skiing, etc.;
  • martial arts;
  • intense physical exertion;
  • riding rides.

Yes, even ordinary sexual intercourse can trigger the release of a large amount of adrenaline into the blood. However, it should be borne in mind that all of the above methods only temporarily put the problem into the background, but in no case do not solve it. Therefore, if a low level of adrenaline is associated with diseases, especially severe( oncological) diseases, it will be impossible to eliminate the ailment without medical intervention.

Only a thorough diagnosis and professional, individual approach to each patient is the key to successful treatment, and increases the patient's chances for recovery. Do not neglect going to the doctor. It is better to let the anxieties be in vain, and you will find yourself completely healthy, than you will suffer the consequences of an ill-treated disease that will not take long to wait!
