The Effect of Alcohol on Blood Pressure and Hypertension

Alcohol has been shown to slow down parasympathetic nervous activity and to stimulate sympathetic nervous activity. Hering 2011, Carter 2011, and Spaak 2008 reported an increase in muscle sympathetic nervous activity (MSNA), which persists for at least 10 hours after consumption. The vagus nerve is a component of the parasympathetic nervous system and is largely responsible for regulation of the heart rate at rest. Rossinen 1997 and Van De Borne 1997 reported withdrawal of vagal tone and reduced heart rate variability within an hour after alcohol consumption; this explains the increased heart rate. Buckman 2015, Van De Borne 1997, and Fazio 2001 also reported reduced baroreflex sensitivity following alcohol consumption. Impairment of baroreflex sensitivity results in failure to sense the increase in heart rate and maintenance of cardiovascular homeostasis.

• They mentioned only that change in blood pressure was not significant.
• Although these values can be helpful, there is some variation in alcohol content.
• However, drinking too much alcohol can create many problems including an increase in blood pressure.
• It’s also important to know that the ways in which alcohol affects your heart will vary from person to person, depending on your age and other conditions you may have.

Your healthcare provider may recommend a blood pressure medication as well. If you continue to drink, alcohol may reduce the effectiveness of these medications or even cause a serious medical interaction. If you have been diagnosed with high blood pressure, you will need to work with your physician to develop a plan to manage it.

How Does Alcohol Impact Blood Pressure?

But your heart is an important organ that should also be cared for, so be sure to drink in moderation, learn about binge drinking and know what your body can (and can’t) tolerate before opening that tab. The study, published Monday in the American Heart Association journal Hypertension, found people who routinely drank even small amounts of alcohol saw blood pressure measurements rise more than those who drank none at all. The analysis examined data from seven studies in the U.S., Korea and Japan. High blood pressure is a common health issue in the U.S. that, if not controlled, can increase the risk of serious medical conditions such as heart attacks, stroke, and heart failure. Light-moderate drinking (defined as up to two drinks a day for men, one for women) has shown a subtle drop in blood pressure in some cases. In small amounts, it has been shown to lower blood pressure by 2 to 4 mm Hg (millimeters of mercury) in women.

• For example, some beers — especially craft beers — can contain about twice as much alcohol as above.
• Individuals who drink alcohol in excess can help improve their overall health by stopping drinking.
• Having higher levels of catecholamines causes the body to excrete less fluid through urine.
• In the case of registration at clinical trials.gov, we considered only one study to have low risk of bias (Barden 2013).
• The current paper, which appears in the journal Nutrients, aimed to review all current studies dealing with the association between alcohol and blood pressure.
• It’s also important to consider why does alcohol raise blood pressure?

Kawano 2000 reported a reduction in plasma potassium levels after alcohol consumption, which might provide another reason for the increase in heart rate. Hypertension can be genetic or may be due to environmental factors such as poor diet, obesity, tobacco use, excessive alcohol consumption, and sedentary lifestyle (Weber 2014; WHO 2013). A population‐based study showed that the incidence of hypertension is higher in African descendants (36%) than in Caucasians (21%) (Willey 2014).

Most of the evidence from this review is relevant to healthy males, as these trials included small numbers of women (126 females compared to 638 males). This systematic review provides us with a better understanding of the time‐course of alcohol’s acute effects on blood pressure and heart rate. This how does alcohol affect blood pressure review included only short‐term randomised controlled trials (RCTs) investigating the effects of alcohol on blood pressure and heart rate. Acute alcohol consumption mimics the pattern of social drinking, and evidence indicates that even one glass of an alcoholic drink can increase heart rate.

But it’s important to make sure those nights of overindulgence are the exception and not the rule. If you’re not sure, make a note to tune into how much you’re having over the course of the next month or so. If it’s more than recommended, try to consciously pace your drinking to help reduce the spike in your blood pressure that excessive alcohol causes. American Heart Association News covers heart disease, stroke and related health issues.

Your doctor can advise you about what makes the most sense for your situation. But that’s not the only reason why your doctor may suggest regularly tracking your blood pressure at home. For example, high blood pressure is one of the risk factors for gout. Cortisol, plasma renin activity (causing vasoconstriction and sodium and water retention), and impaired endothelial function (inhibiting vasodilatory responses and promoting oxidative stress) have also been reported in heavy drinkers. A cardiologist explains how alcohol affects your heart and why moderation is key, especially if you live with other health conditions. Dr. Cho also warns that if you have liver dysfunction or take other medicines that are processed through the liver, your risks might be different.

Excessive alcohol consumption can increase the risk of several metabolic conditions, including high blood pressure. Caffeine and nicotine constrict blood vessels and boost your heart rate, which can raise blood pressure. It makes sense to reduce common risk-factors of alcohol and blood pressure and to try to break the addictive hold of alcoholism. Note that the elevated blood pressure may also be one of the alcohol allergy symptoms. It is okay to have drinks in moderation if you are a healthy individual. The findings of this review support the current recommendations to avoid alcohol.

For anyone suffering from alcoholism, it’s important to know that whether it is a wine addiction or, a dependency on spirits, the risks are the same. Can alcohol raise blood pressure and does alcohol raise blood pressure the next day? Certainly, large quantities of drink or, where alcoholism is present, the risks for hypertension increase. The effects of alcohol on the heart can also lead to a stroke – this should by seriously.

But alcohol can lead to your heart rate temporarily jumping up in speed, and if it goes over 100 beats per minute, it can cause a condition called tachycardia. Too many episodes of tachycardia could lead to more serious issues like heart failure or going into irregular rhythms, which can cause heart attack and stroke. High blood pressure due to alcohol use can be reversible by reducing your intake and following your treatment plan. However, long-term or severe hypertension can have other complications that may last for longer. One of the most appropriate ways to reduce alcohol-induced high blood pressure is to reduce your alcohol intake as much as possible.
