Is alcohol withdrawal good for high blood pressure?

The US study found that in 5,000 people aged 30-59 years, the amount of alcohol consumed was positively correlated with blood pressure levels, which means that the more alcohol they drink, the higher their blood pressure levels.

Our country’s research found that the average daily drinking of white wine 30ml, its systolic blood pressure can be increased by 4mmHg, diastolic blood pressure can be increased by 2mmHg, the prevalence of hypertension is 50%; while daily drinking of white wine 60ml, systolic blood pressure can be increased by 6mmHg, diastolic blood pressure It can be increased by 2 to 4 mmHg, and the prevalence of hypertension is 100%.

Therefore, China’s guidelines for prevention and treatment of hypertension clearly indicate that excessive drinking is a risk factor for hypertension, and the prevalence of hypertension in the population will increase with the increase in alcohol consumption.

In addition, the effect of drinking on high blood pressure is not related to the type of alcohol, but to the amount of alcohol consumed, that is, whether it is red wine, white wine, beer, or wine, as long as the alcohol intake is excessive, it will increase the blood pressure. Risk of illness.

Excessive drinking leads to high blood pressure

  1. Related to the harmfulness of acetaldehyde

The main component of alcohol is ethanol. Ethanol is metabolized into acetaldehyde by the action of alcohol dehydrogenase in the body. Acetaldehyde is metabolized into acetic acid and water by the action of acetaldehyde dehydrogenase. Ethanol and acetic acid have no activity on the human body, but acetaldehyde is not. Many people have symptoms such as red face, rapid heartbeat, headache, dizziness, nausea and vomiting, and lethargy and coma after drinking. All of them are acetaldehyde, because acetaldehyde can cause The blood vessels contract and the heart rate increases, so it causes an increase in blood pressure.

In addition, acetaldehyde can activate the sympathetic nervous system, leading to the release of adrenaline, which activates the renin-angiotensin-aldosterone system, leading to the release of angiotensin II, which can cause elevated blood pressure. .

Therefore, whether or not you can drink alcohol depends on the amount of acetaldehyde dehydrogenase in the body. People who can’t drink alcohol have very low levels of acetaldehyde dehydrogenase. The acetaldehyde produced after drinking can’t be metabolized in time and accumulate in the body, which brings various “drunk” symptoms. People who can drink alcohol have high levels of acetaldehyde dehydrogenase, and acetaldehyde can be quickly metabolized into water and acetic acid, so they can continue to “combat.”

  1. It is related to the increase in intake of sodium salt.

Most people drink a lot of food at the same time, resulting in a significant increase in sodium intake, while also ingesting high levels of protein and fat. The high-salt diet is also a major cause of high blood pressure.

Excessive drinking can increase the mortality rate of hypertension

A controlled study found that hypertensive patients who consumed 50 ml of white wine had higher mortality than those who did not drink, and most of the causes of death were related to alcohol.

Limiting alcohol consumption can reduce the risk of high blood pressure

Several large randomized controlled clinical trials have observed that if hypertensive patients reduce their alcohol consumption, they can reduce systolic blood pressure by 5 to 8 mmHg and diastolic blood pressure by 2 to 3 mmHg.

China’s guidelines for the prevention and treatment of hypertension clearly state that if the daily drinking amount is up to standard (ie, the daily alcohol intake is <25g for men and <15g for women), the blood pressure can be lowered by 2~4mmHg. Therefore, people with high blood pressure are not recommended to drink alcohol. If you want to drink alcohol, you should have a small amount (corresponding to liquor, wine or rice wine, beer, <50ml, 100ml, 300ml respectively).

In summary, long-term heavy drinking can lead to increased blood pressure and increase mortality in hypertensive patients, while reducing alcohol consumption or abstinence can lower blood pressure.

Therefore, abstinence is definitely good for high blood pressure.

For patients who have already developed alcohol dependence, they can’t tough alcohol, otherwise they will easily lead to withdrawal, leading to convulsions, elevated blood pressure and even death. Therefore, alcohol dependent patients should gradually stop drinking under the guidance of a professional doctor.
