What are the dangers of alcohol and what are the dangers of alcohol

1.Effects on the brain, ethanol that enters the human body cannot be digested and absorbed, and will enter the brain with the bloodstream. In the brain, ethanol disrupts neuronal cell membranes and binds indiscriminately to many neuronal receptors.

Alcohol weakens the central nervous system and causes brain activity to be delayed by activating inhibitory neurogens (gamma aminobutyric acid) and inhibiting activating neurogens (glutamate, nicotine). Disorders of gamma aminobutyric acid neurogen and the secretion of opioids (anxiolytic, anti-pain) in the body lead to a sharp secretion of dopamine. Opioids in the body are also involved in the autoregulation of dopamine secretion.

Alcohol can have an effect on memory, decision-making, and bodily reflexes, and can lead to drunkenness, lethargy, and sometimes nausea. Drinking too much alcohol can lead to alcohol-toxic coma.

2.Tolerability and dependence, with the effect of hepatic degradation of ethanol becoming more pronounced over time (shortened duration of drunkenness). The brain adjusts the number and sensitivity of neurogen receptors in response to this condition to shorten the duration of sedation and enhance the effects of drunkenness.

The autoregulation of dopamine secretion is disrupted, making rewards and bribes extremely sensitive. The neuronal cell membrane becomes stiff and its permeability is weakened. To return to a drunken state, it is necessary to increase the amount of alcohol consumed (tolerance), but at the same time the effect of alcohol will be stronger (sensitization).

3.Harmful alcohol can cause excessive calcium levels in neurons, stiffen neuronal cell membranes, and disrupt the exchange of substances between nerve cells and their surroundings. A large number of nerve cells will die as a result.

Various cognitive functions are also affected by this (especially memory, analytical ability, and attention). Drinkers experience psychological problems, anxiety, and depression. Exactly the overall toxicity can lead to cardiovascular disease, damage to nerve and muscle fibers, liver disease, cancer of the digestive tract.

Alcohol can also hinder the normal development of the fetus.

For patients who are accustomed to using alcohol to disinfect their fingers, the results of blood glucose measurement at home are often very skewed.

Because alcohol is disinfected and the alcohol is not dry, the alcohol may mix with the blood droplets, thereby reducing the glucose concentration in the blood being measured, so the blood glucose value is low.

At present, the diabetes test strip commonly used in the family, a substance in the test strip reacts with glucose in the blood to produce another colored compound, and the blood glucose concentration value is read out through this color reaction. But alcohol is able to destroy the substance in the test strip, which weakens the color reaction, giving you the illusion that your blood sugar levels are low. In addition to causing inaccurate measurements, alcohol can also dry out, and as a result, those close to the nails are prone to chapping.

If the needle is inserted before the alcohol has completely evaporated, it can cause pain after the alcohol is immersed in the eye of the needle.

Acute alcohol intoxication caused by heavy alcohol consumption can be fatal. Even small amounts of alcohol can cause chronic poisoning. It also makes the heart limp, contractile weakness, heart swelling, and hardening of the arteries.

Drinking alcohol often is also bad for the lungs, and it is easy to get tracheitis, emphysema, pneumonia and tuberculosis. Drinking alcohol is more likely to cause stomach problems and stomach cancer. Alcohol, in particular, can damage the liver and make it susceptible to cirrhosis.

In addition, young people are developing and growing, such as regular drinking, in addition to the above harmful effects, it can also cause brain and memory loss, muscle weakness, precocious sexual development and premature aging.

Anyone who drinks alcohol will have alcoholic liver, which can develop into a virus, usually hepatitis B and hepatitis C. Then there is cirrhosis, liver cancer.

Drink more and make mistakes, and moderate moderation is best. It is beneficial to activate the body and speed up metabolism.

Alcohol is obviously harmful to the human body, and patients often consume alcoholic beverages for a long time or in large quantities, which will cause harm to the digestive system, circulatory system, and nervous system.

Alcohol has many harms to the human body, the most important thing is that it affects the nervous system of the human body, resulting in the body's cognitive ability, reaction ability, memory ability, etc. Long-term alcohol consumption can lead to impaired liver function and even cirrhosis, which can lead to liver cell death and may lead to liver cancer. Alcohol can also affect the function of the gastrointestinal tract, leading to excessive secretion of gastric acid, causing indigestion and even developing chronic gastritis.

In addition, alcohol can affect the cardiovascular system, leading to constriction of blood vessels, increased blood pressure, heart attacks, and even death. Alcohol can also affect the nervous system and cause mental illnesses such as depression, anxiety, etc. In addition, alcohol can affect the reproductive system, leading to sexual dysfunction and even infertility.

In conclusion, alcohol has a lot of harm to the human body, so you should avoid drinking heavy alcohol for a long time to protect your health.
