Alcohol: Does it affect blood pressure?

A dose of 14 grams of pure alcohol/ethanol or less was defined as a low dose of alcohol. We excluded 450 trials after reviewing the full‐text articles, and we recorded the reasons for exclusion (see table Characteristics of excluded studies table). The search was conducted up to March 2019 and resulted in 6869 citations. After de‐duplication and screening of titles and abstracts, we were left with 482 citations for further assessment. We retrieved full‐text articles for those citations and included 32 studies (Figure 1).

  • K Health offers affordable and convenient access to highly qualified doctors to treat and manage high blood pressure, as long as you are not having a hypertensive crisis.
  • Alcohol abuse refers to the excessive or problematic consumption of alcohol that interferes with a person’s daily life and health.
  • The elevation in blood pressure that alcohol creates generally occurs about 12 hours or more after drinking.
  • McFadden 2005 included both randomised and non‐randomised studies with a minimum of 24 hours of blood pressure observation after alcohol consumption.
  • Some scientists suggest a J-shaped curve between alcohol and CVD, but this remains a hypothesis.

Long-term alcohol use can cause a number of cardiovascular and mental health problems. People who drink heavily are at a higher risk for health problems compared to people who do not drink. If your systolic and diastolic blood pressure are over 130 and 80 mm Hg, respectively, you may have hypertension.

Can Someone With High Blood Pressure Drink Alcohol?

This is unfortunate, as we have reason to believe that the effects of alcohol on BP might be greater in women. In the case of registration at clinical, we considered only one study to have low risk of bias (Barden 2013). The trial was registered with the Australian New Zealand Clinical Trials Registry (ANZCTR). We classified the remaining studies as having high risk of bias because the protocol was not registered and the study identifier was not reported.

how does alcohol affect your blood pressure

Alcohol prevents the body’s baroreceptors from detecting a need to stretch the blood vessels and increase their diameter, causing an increase in blood pressure. When blood pressure decreases, these receptors help minimize how much the blood vessels stretch to increase blood pressure. Similarly, when blood pressure increases, these receptors increase the stretching of the blood vessel walls in order to decrease blood pressure. Alcohol increases blood levels of the hormone renin, which causes the blood vessels to constrict. Notably, studies have shown that alcohol dehydrogenase variants occur in different individuals and that categorization according to variant nullifies the protective effect of moderate alcohol intake.

Platelets also release proteins called clotting factors that form a plug to close the hole.

As planned, we conducted sensitivity analyses to see if there was any significant difference between effect estimates of outcomes given by the fixed‐effect model and the random‐effects model, when substantial heterogeneity was present. The result is presented in Table 6; there was no significant difference between results given by the two models. The Cochrane Hypertension Information Specialist searched the following databases without language, publication year, or publication status restrictions.

The sooner you can access treatment for addiction, the sooner you will be able to reverse any potential damage done to your body. A comprehensive treatment program will address your physical, mental, and emotional needs, helping you return to a healthy life free from substance abuse. You can get the appropriate medical care you need as well as the mental health care needed to live a long life in recovery. AHA describes cocaine, for example, as the “the perfect heart attack drug” due to common cardiovascular symptoms found in regular cocaine users and the typical sides effects of cocaine.

Moderate‐certainty evidence indicates an increase in heart rate after 7 to 12 hours and ≥ 13 hours after high‐dose alcohol consumption, low certainty of evidence was found for moderate dose of alcohol consumption. Hence, we conducted additional analyses to see if the very high dose of alcohol (≥ 60 g or ≥ 1 g/kg) had any dose‐related effects compared to lower high doses of alcohol (31 to 59 g of alcohol) (see Table 9). Results suggest that the decrease in BP with very high doses of alcohol is greater compared to lower high doses of alcohol. However, the result was heterogeneous; therefore, we are unable to make any implications from this.

Recreational users of cocaine are more likely to have high blood pressure, stiffer arteries, and thicker heart walls than non-users. These symptoms, combined with the cardiovascular effects of cocaine, are a recipe for an overdose. Experimenting with drugs that impact heart rate and blood pressure exposes you to the potential for overdose. The American Heart Association (AHA) warns that most recreational drugs have the potential for negative cardiovascular effects, the most severe of which is a fatal heart attack. More than two drinks per day, however, can damage your circulatory system. Too much alcohol can inhibit proper heart functioning and prevent blood from being effectively pumped throughout the body.

  • Conversely, moderate drinking has been repeatedly demonstrated to have potential benefits for patients with diabetes and abnormal lipoprotein profiles.
  • Moreover, not only does drinking cause elevated blood pressure, but in excess, it can directly enhance the damage caused to cardiac and renal tissues by hypertension.
  • If a person is already suffering from hypotension (low blood pressure), this could worsen the condition.
  • If we were not able to get SD from the study authors or calculate SD from the values mentioned above, we imputed SD using the following hierarchy (listed from highest to lowest) (Musini 2014).

The blood alcohol level decreased over time, and 20‐HETE started to rise (Barden 2013). The hypertensive effect of alcohol after 13 hours of consumption could be the result of the rise in vasoconstrictors and the homeostatic response to restore blood pressure. Plasma renin activity was reported to be increased in Kawano 2000 as a late effect of alcohol consumption. Two review authors (ST and CT) performed data extraction independently using a standard data collection form, followed by a cross‐check. In cases of disagreement, the third review authors (JMW) became involved to resolve the disagreement.

Taking both together could compound the anticoagulant effect and increase your risk of bleeding. But in people who drink heavily, there can be a rebound effect in which the bleeding risk increases, even after they’ve stopped drinking. Exceeding the recommended guidelines above is considered heavy drinking.

A stroke, aside from potentially being fatal, can cause disabilities in speech, movement, and other basic activities. Lastly, high blood pressure during middle age has been linked to poorer cognitive function and dementia later in life. You may have heard two numbers whenever you get a blood pressure reading. The first number indicates how much pressure is being exerted against the walls of your arteries when your heart beats and is referred to as systolic blood pressure.

Will Quitting Alcohol Lower My Blood Pressure?

Drinking excessive alcohol is considered one of the most common causes of raised blood pressure. We wanted to quantify the effects of a single dose of alcohol on blood pressure and heart rate within 24 hours of consumption. As soon as levels of alcohol consumption increase beyond a moderate amount, the risk of developing coronary heart disease, hypertension, stroke, and death increases significantly.
