How does alcohol affect blood vessels?
Many people think that alcohol has beneficial effects on human blood vessels. It is a delusion. There is indeed a positive effect after drinking, but it is short-lived. Next we will talk about the effects of alcohol on blood vessels and explain whether it can be used as a remedy.
Alcohol narrows or dilates blood vessels
Initially, alcohol dilates the blood vessels, but it increases the number of contractions of the heart muscle, which leads to an increase in blood volume that is ejected. Such an act affects a person's condition.
After a few minutes, ethanol enters the bloodstream and remains there for about seven hours. This leads to an increase in heart rate, circulatory disorders and metabolic processes.
Many hormones are released into the blood - norepinephrine and adrenaline, which often leads to mental disorders and stress.
Influence of spirits
no matter what alcohol you drink - strong or weak, the effects of alcohol depend on such factors:
- Volume taken on the chest (larger amount increases blood pressure).
- Age. Over the years, the body weakens, alcoholic beverages cause disorders of the kidneys, liver.
- Regularity of the use of alcohol.
The complete elimination of hot drinks is recommended for people with vegetative dystonia, neuroses and endocrine diseases.
Effects on the brain
People who consume alcohol six times more often suffer from pathologies of the vessels of the brain. You will be diagnosed with a number of ailments:
- Encephalopathy is a disease that is accompanied by destruction of brain cells in the head under the influence of alcohol.
- Ischemic stroke - acute circulatory disorder, accompanied by necrosis of the brain area.
- Vascular atherosclerosis is the damage to blood vessels as a result of the deposition of lipids on their internal surface.
- VSD is a disease underlying the violation of the regulation of the vascular tone of the autonomic nervous system.
All pathologies take place in severe form and are accompanied by mental disorders. It can take more than three years to return to normal.
Under the influence of alcoholic beverages, the permeability of the vessels of the head increases, which is often the cause of swelling.
Erythrocytes are destroyed when hunger of a brain is provoked as insufficient volume of oxygen and nutrients arrives to it. This, in turn, leads to the death of nerve cells, affects the cortex of the brain.
Lawsuit alcohol principle
dilated or narrowed blood vessels, alcohol can be understood by the effects of alcohol on their walls:
- Immediately after drinking alcoholic beverages, vessels widen, the person gets better. Arterial pressure decreases, the vessels relax, the blood moves slightly, the number of contractions of the heart increases.
- Then there is a sharp narrowing of the vessels, the pressure increases, metabolic processes are violated, which affects the cells and tissues.
- These states alternate, the frequency of the shift depends on the amount of alcohol consumed.
- Violation of the cardiovascular system, increased the load on the heart.
This condition lasts until the complete release of alcohol from the blood, because the body struggles with toxic ethanol. The withdrawal of toxins occurs through the liver.
How alcohol affects the blood vessels of people with high cholesterol, atherosclerosis
Alcohol affects cholesterol in small amounts which is beneficial. Atherosclerosis significantly affects the arteries against the background of the accumulation of salts on their walls. The latter become denser, their elasticity deteriorates, the diameter decreases, there is a high risk of blood clots.
With increasing pressure, the risk of vascular ruptures or narrowing increases significantly. Often this causes a cerebral infarction with the death of tissues, a stroke. It is not excluded the development of a heart attack of the liver, spleen, intestines, heart.
Why can alcohol cause vasospasm?
With headaches, alcohol gives considerable relief. This is due to the fact that the spasms of the vessels are eliminated, their lumen increases. The effect is short-lived. When the effects of alcohol weaken, the pain syndrome returns, and often the condition worsens.
Some people repeatedly use alcohol, which is strictly prohibited. Eliminate the headache can be used through the use of analgesics without alcohol.
Harm to alcohol for blood vessels
The harm from alcohol is obvious. It causes injury to the heart and blood vessels because of the excess of adrenaline and noradrenaline when it is used. With an increased number of contractions of the heart muscle, clumping of erythrocytes is observed, which can clog the lumen (a characteristic grid is visible on the skin).
The brain's capillaries fail to withstand the stress and are destroyed, causing the micro-shock that is often mistaken for a hangover. Cells in the brain that are under the normal influence of alcohol begin to die, making a person's condition worse.
What pathology alcohol
Repeated exposure to ethanol can lead to a number of vascular diseases:
- hypertensive crisis developed.
- Kidney diseases are chronic in nature.
- Pressure amplification.
- Coronary artery insufficiency in acute form.
- Cardiac disorder.
Alcoholic drinks increase mortality among young people and cause strokes and heart attacks, ischemic diseases.
Alcoholism and the Myth of Healing the Vessels
Many people mistakenly believe that drinking alcohol in small doses is beneficial. It is a delusion. What's really going on here:
- Alcohol relaxes the body, but in the morning the person suffers from hangover syndrome, accompanied by pain in the head.
- Ethanol helps relieve pain, but after a period of time the symptom manifests itself with a double force.
- Alcohol lowers high blood pressure, but leads to vascular deterioration, diseases of the blood vessel system.
People who drink alcohol say that it has a beneficial effect on vascular disease. However, it should be remembered that a change in the constriction and expansion of the vessels leads to a disruption of the speed of movement of blood.
As a result there are constant jumps in pressure, later there are regular headaches, tinnitus. Acute effects of alcohol
Ethyl alcohol, contained in intoxicating drinks, is absorbed into the digestive tract and enters the blood vessel wall by relaxing it. This is observed against the background of the fact that alcohol inhibits the production of neurotransmitters in the nerves of blood vessels.
a short time after this case:
- partial paralysis of the vessel walls, increasing their diameter.
- Decrease in the resistance of blood vessels.
- Reduced blood pressure.
This state does not last long, then the reverse action begins.
Effect of frequent drinking of
After a few minutes of relief after drinking, the smooth muscles of the vessels are restored, the pressure increases. Each dose of alcohol relaxes the blood vessel walls, and the body tries to restore the changes. Such a struggle leads to fatigue in the person, the intoxication begins.
During metabolism of ethanol it produces acetaldehyde, which is more toxic but drunk feels weakness until the substance is completely dissolved. Prolonged use of alcohol
provokes a thinning of the vessel walls, their permeability increases, whereby the plasma exits into the surrounding tissue. As a result, on the background of swelling, there is dehydration, there is no water deficit.
Acetaldehyde is toxic to the liver and pancreas. The amount of cholesterol increases, it accumulates on the walls of the vessels in the form of atherosclerotic plaques. This becomes the cause of the fragility of the walls of blood vessels, they lose elasticity, their performance is impaired.
With prolonged abuse of alcohol, cirrhosis of the liver develops, the tissues of the organ become deformed. The portal vein is depressed, the blood stagnates, which leads to a stretching of the vein walls. As a result, ascites is formed.
Are there any positive effects of alcohol consumption?
All cells, organs and tissues receive nutrients and oxygen due to the circulatory system. With the narrowing and widening of the vessels, the work of the entire organism deteriorates. The most negative situation occurs when there are too few vitamins and nutrients in the body.
Many doctors prove that alcohol in small doses is useful for a person and has a beneficial effect on the condition of blood vessels.
Minimally reduces blood pressure under the influence of ethanol. As a result, the vessels become less elastic and expand, the blood reaches all organs without problems.
When you drink alcohol, it becomes easier for a person, but this phenomenon has the opposite effect.
Regular drinking of alcohol in large quantities often causes serious complications. Negative consequences can be attributed to a number of factors.
Above all, it is about side effects on the cardiovascular system. After the penetration of alcohol into the blood vessels, they alternately contract and expand until acetaldehyde is completely released from the body. As a result, they wear out quickly.
In the event of alcohol abuse, the containers cannot withstand constant pressure interruptions and breaks at any time. This is the cause of the development of strokes, heart attacks, bleeding. Arrhythmia, thrombosis and varicose veins can be observed.
Alcoholics often receive alcohol accompanied by a sedentary lifestyle and the abuse of tobacco products. In this situation, the heart and blood vessels suffer twice as much.
