Alcohols Effects on the Heart
There are many different reasons why alcohol raises your blood pressure – it releases various hormones, like cortisol and renin, that cause your blood vessels to constrict and blood pressure to increase. Alcoholic beverages are often high in sugar and calories, which can also contribute to high blood pressure by causing weight gain. While becoming sober helps normalize a person’s blood pressure in the long term, people who want to stop drinking should know about alcohol withdrawal and blood pressure. It can cause symptoms like anxiety, shaking, nausea, sweating and trouble sleeping. Someone who is detoxing from alcohol usually has elevated blood pressure. This problem is worse in people who drink heavily or have been drinking for longer time periods.
This measurement takes into account the systolic blood pressure and the diastolic blood pressure. Some evidence suggests that reducing alcohol intake in heavy drinkers could help reduce BP, but much more research is required to validate these observations. 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. Some scientists suggest a J-shaped curve between alcohol and CVD, but this remains a hypothesis. In fact, over the long term, Blacks appear more prone to BP elevations than Whites or Asians. In one study, the risk for high BP among men increased by a fifth with 1-2 drinks but by half and three-fourths with 3-4 and 5 or more drinks a day.
Health benefits of avoiding alcohol
Rosito 1999 tested the effects of 15 g, 30 g, and 60 g of alcohol on 40 young medical students. The decrease in SBP was greater with 30 g of alcohol seven hours after consumption compared to placebo and 15 g and 60 g alcohol‐consuming groups. In this study, alcohol had no significant effect on DBP in the four groups.
How much does alcohol raise your blood pressure?
The magnitude of the increase in blood pressure in heavy drinkers averages about 5 to 10 mmHg, with systolic increases nearly always greater than diastolic increases. Similar changes in blood pressure were also reported in preclinical studies[19-22].
High blood pressure (or hypertension) is a major health issue in the United States, but when combined with alcohol, it can become an even more serious issue. Below we highlight the effects alcohol can have on your blood pressure, as well as the negative consequences that having high blood pressure can have on your health. Individuals who drink alcohol in excess can help improve their overall health by stopping drinking.

Alcohol can thin your blood, because it prevents blood cells from sticking together and forming clots. This may lower your risk for the type of strokes caused by blockages in blood vessels.
- The Joint Commission for the Accreditation of Healthcare Organizations evaluates quality of care provided by healthcare organizations.
- Over time, however, chronic high blood pressure can take its toll on your arteries, heart, brain, and kidney, eventually leading to heart attack or stroke if left untreated.
- There is some evidence that moderate amounts of alcohol in particular red wine might help to slightly raise levels of good cholesterol, however physical activity can also boost your HDL cholesterol without the need for a glass of wine.
- Alcohol has been reported to diminish baroreceptor sensitivity, which is a key factor in regulating blood pressure (Abdel‐Rahman 1985; Rupp 1996).
- If you think you or someone you know is experiencing any symptoms of an overdose, it is imperative that you get emergency medical help right away.
- Alcoholic beverages are often high in sugar and calories, which can also contribute to high blood pressure by causing weight gain.
A population‐based study showed that the incidence of hypertension is higher in African descendants (36%) than in Caucasians (21%) (Willey 2014). Proper management of hypertension can lead to reduction in cardiovascular complications and mortality (Kostis 1997; SHEP 1991; Staessen 1999). Another reason behind the heterogeneity was probably the variation in alcohol intake duration and in the timing of measurement of outcomes across the included studies.
Potential biases in the review process
Above 14 drinks a week, heart failure risk is higher, with hypertensive patients who drink more being more likely to show subclinical features of heart damage affecting the heart’s diastolic function. This is a dose-dependent association, as is that with left ventricular hypertrophy. Elevated uric acid levels could mediate this due to alcohol consumption. A recent study shows the least mortality at 100 g/week or less of alcohol, with a dose-dependent relationship between alcohol and stroke, IHD, fatal hypertensive disease, heart failure, and fatal aortic aneurysm. Notably, the heart attack risk was in inverse relation to alcohol consumption levels.
Anyone concerned about high blood pressure should cut back on their drinking and speak to their doctor about how alcohol use may be affecting their health. With moderate doses of alcohol, blood pressure (BP) went up for up to seven hours but normalized after that. A biphasic response was observed with high doses of alcohol, with an initial decrease in both systolic and diastolic blood pressure (SBP and DBP, respectively) for up to 12 hours, increasing at more than 13 hours from consumption.
Get Help for Alcohol Use and High Blood Pressure
One study that was published in Alcohol and Alcoholism analyzed 147 detoxing patients for 18 days. While blood pressure increased in 55% of the patients on day one of the detoxes, by the last day, only 21% showed signs of elevated blood pressure. In summary, the evidence suggests that as long as you give your body a period of time to recover, blood pressure should decrease. Light to moderate amounts of alcohol use may not have a meaningful impact on blood pressure; however, heavy drinking can. The elevation in blood pressure that alcohol creates generally occurs about 12 hours or more after drinking.
- Like any other dietary or lifestyle choice, it’s a matter of moderation.
- Hypertension, or high blood pressure, is a very common condition worldwide.
- Both reviewers (ST and CT) rated the certainty of evidence independently by examining risk of bias, indirectness, inconsistency, imprecision, and publication bias.
- Only four studies included almost equal numbers of male and female participants (Buckman 2015; Foppa 2002; Maufrais 2017; Zeichner 1985).
- Low‐dose alcohol increased heart rate (HR) within six hours, suggesting that even one glass of wine increases HR.
- Mean difference (MD) from placebo with 95% confidence interval (CI) was the outcome measure, and a fixed‐effect model was used to combine effect sizes across studies.
