How Does Alcohol Affect Blood Pressure?

High blood pressure is prevalent worldwide. This can increase your risk of various health complications such as heart failure, stroke, and heart attack. Many factors may contribute to the increase in your blood pressure. Do you know that alcohol and high blood pressure are linked together?

Alcohol And High Blood Pressure

High blood pressure, also known as hypertension, occurs when there is an increase in your blood pressure to unhealthy levels. Alcohol abuse is one of the causes of high blood pressure.

Your blood pressure will most likely increase if you drink three or more alcoholic drinks in one sitting. Being a heavy drinker will make you at risk of long-term high blood pressure. It was shown that heavy drinking could harden and narrow your arteries, thereby leading to a stroke or heart attack. Moreover, alcohol is rich in sugar and calories. This will further make you prone to high blood pressure. Aside from hypertension, obesity is also linked to high blood pressure.

If you already have high blood pressure, you can drink alcohol but only in moderation. But to be safe, it is best to avoid drinking.

But if you are a woman, you can have one drink a day, and it applies to all age groups.

Anyway, one drink is equivalent to 5 ounces of wine, 12 ounces of beer, or 1.5 ounces of 80-proof distilled spirits. Although heavy drinkers are required to reduce their alcohol intake to improve their blood pressure levels, it should be done slowly. The sudden stop may make your blood pressure more serious.

Alcohol And Low Blood Pressure

Low blood pressure may mean that your blood pressure is less than normal which is 120/80. Although it is good in most cases, this can make you feel dizzy and tired. This may also be an indication of an underlying health condition.

Although alcohol consumption is not popularly linked to low blood pressure, instead of high blood pressure, it also affects lowering your blood pressure. Several studies have shown that moderate drinking can provide health benefits for your heart, as well as lower your blood pressure.
