Other studies reported an expansion of the extracellular fluid after alcohol consumption which has been shown to elevate the systolic blood pressure in rats60,61. It has been reported that a significant increase in plasma renin activity in patients consuming heavy alcohol compared to mild or moderate alcohol consumption55,57,58. Several studies reported increased sympathetic nervous system activation and discharge of sympathetic amines after alcohol consumption43,48,49. When undetected or left untreated, AFib can lead to serious health complications such as blood clots, cognitive impairment/dementia, heart failure, stroke, and cardiac arrest.13 Some evidence suggests that heavy drinking increases the risk of sudden cardiac death, and fatal arrhythmias such as AFib are the most likely cause.14 The relationship between alcohol intake and blood pressure is dose-dependent, meaning that as alcohol consumption increases, so does the likelihood of elevated blood pressure.
According to at least one study, chronic heavy drinkers have at least twice the risk of bleeding in the brain compared to nondrinkers.4 The increased risk is likely linked to alcohol-related AFib and cardiomyopathy, which can both predispose people to the formation of blood clots or the spread, growth, or transmission of existing clots. The connection between alcohol and ischemic stroke occurs mostly in relation to other cardiovascular problems, such as hypertension, arrhythmias, coronary artery disease, and alcoholic cardiomyopathy.4 In addition to heart attacks, CAD can lead to various complications, such as a weakened heart muscle and heart failure (i.e., when the heart can’t effectively pump enough blood to the rest of the body).16
We included any type of alcoholic beverage as the intervention arm. However, they excluded studies for which the duration of BP observation was less than 24 hours and articles published in non‐English languages. In contrast, women eliminate alcohol from the body a little faster than men (Thomasson 2000). Alcohol has been reported to diminish baroreceptor sensitivity, which is a key factor in regulating blood pressure (Abdel‐Rahman 1985; Rupp 1996). The molecular mechanisms through which alcohol raises blood pressure are unclear. Although alcohol metabolism by the liver is well characterised, its metabolism in other parts of the body is not well defined.
Routinely drinking alcohol may raise blood pressure even in adults without hypertension
No matter how much you drink, damage begins from the first drop you drink. The World Health Organization warns that alcohol is a toxin and no amount is safe. Having four or more drinks weekly significantly raises your risk of cardiovascular disease, cancer, and mortality. Alcohol’s potential health benefits are increasingly being questioned. This may partly be due to alcohol’s blood-thinning ability, but it primarily occurs for other reasons. You need to take a precise dose of an effective Genetics and alcoholism medication to stay healthy.
Moderate alcohol consumption, defined as one drink a day for women and up to two drinks a day for men, may have minimal effects on blood pressure alcohol. But excessive drinking can have negative effects on the body, including the heart. Lowering alcohol consumption will reduce the chances of high blood pressure-related side effects.
- People who have pre-hypertension are at higher risk of developing high blood pressure.
- Also, multiple studies have found associations between consumption of alcoholic beverages and specific cancers (Seitz 2007; Kushi 2012).
- Low‐dose alcohol increased heart rate (HR) within six hours, suggesting that even one glass of wine increases HR.
- Alcohol is high in calories and sugar and may contribute to an increase in body weight and obesity; which can further elevate the risk of high blood pressure on a long-term basis.3,9,11
- Where there is substantial and unexplained heterogeneity, we will pool data using the random‐effects model.
- That’s the same as 6 pints of beer or 6 small glasses of wine.

Although anyone can develop high blood pressure, there are certain factors known to increase a person’s risk, such as consuming alcohol.3 High blood pressure, or hypertension, is when a person’s blood pressure stays elevated longer than normal.4 When it stays high over time, it causes the heart to consistently pump harder.3 “Alcohol is certainly not the sole driver of increases in blood pressure; however, our findings confirm it contributes in a meaningful way,” Vinceti said. Diastolic blood pressure rose 1.14 mmHg over the study period in men who drank an average 12 grams of alcohol per day and 3.1 mmHg in men who drank an average 48 grams of alcohol per day. In people who drank an average of 48 grams of alcohol per day, systolic blood pressure rose 4.9 mmHg over the study period.
Effects of Alcohol on the Cardiovascular System
This sustained high blood pressure, known as hypertension, can lead to heart disease over time. For those with already high blood pressure, the avoidance of alcohol or moderation in its consumption is advised . According to the Mayo Clinic, alcohol can increase blood pressure by up to 5 mmHg. Moderate drinking may help maintain your good cholesterol levels, but drinking can also increase levels of bad cholesterol and triglycerides. Alcohol can increase blood pressure, damage your heart, cause strokes, and has an unpredictable blood-thinning effect that you can’t rely on.
- There is no singular recommended level of alcohol for people who have high blood pressure aside from reducing your intake as much as possible.
- Even though Dumont 2010 mentioned blinding of outcome assessors, it is not clear whether blinding of outcome assessment was maintained in the case of blood pressure and heart rate measurements.
- Alcohol stimulates the secretion of corticotrophin releasing hormone in rats69,70 leading to stimulation of cortisol secretion, sympathetic stimulation and hypertension in rats.
- You should never assume that even a small amount of alcohol is safe until you have first talked to your physician.
- 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.
- Alcohol has been reported to diminish baroreceptor sensitivity, which is a key factor in regulating blood pressure (Abdel‐Rahman 1985; Rupp 1996).
- Our professionals have put together a 7-step process to cut back on drinking.
The American Heart Association recommends that men consume no more than two alcoholic drinks per day and that women consume no more than one per day. Doctors consider your blood pressure to be at a healthy level if your systolic blood pressure is less than 120 and your diastolic blood pressure is less than 80. In the short term, a small amount of alcohol may not affect your blood pressure, but a large amount can raise it. Interestingly, high-dose alcohol has a how long does molly stay in your blood biphasic effect on blood pressure. A drink is defined as 12 ounces (355 milliliters) of beer, 5 ounces (148 milliliters) of wine, or 1.5 ounces (44 milliliters) of 80-proof distilled spirits. For healthy adults, this means up to one drink a day for women and up to two drinks a day for men.
Consulting with a healthcare professional can provide more personalized guidance based on individual health conditions and lifestyle factors. Alcohol, particularly when consumed in excess, can have a substantial impact on blood pressure. Ultimately, you must consider your unique health and risk factors.
It’s important to remember that while moderate alcohol consumption can be a part of a healthy lifestyle, excessive drinking can lead to serious health issues, including hypertension and heart disease. Regular moderate alcohol use of 30 g per day can significantly increase your risk of hypertension, and drinking alcohol regularly can have other negative effects on your heart. While moderate alcohol consumption may have a small impact on reducing the risk of heart disease, heavy drinking can result in high blood pressure .

One immediate effect is the stimulation of the sympathetic nervous system, which can constrict blood vessels and increase heart rate. Below, we explore how alcohol can raise or lower blood pressure, who might be at risk, and steps you can take to protect your heart. Understanding how alcohol influences blood pressure is essential for anyone interested in maintaining or improving cardiovascular health.
For the planned subgroup analysis based on sex, no studies reported male and female participant data separately. We noted some overlap of data points in some funnel plots, indicating reasons to attend aa meetings and how often to go that some of the included studies were of similar size. We interpreted only funnel plots that were constructed based on studies reporting outcomes under medium dose and high dose of alcohol versus placebo comparisons.
We are also moderately certain that high‐dose alcohol decreased blood pressure within six hours, and the effect lasted up to 12 hours. Although these trials included adults from 18 to 96 years of age with various health conditions, most study participants were young healthy males. High‐dose alcohol increases HR at all times up to 24 hours. To determine short‐term dose‐related effects of alcohol versus placebo on systolic blood pressure and diastolic blood pressure in healthy and hypertensive adults over 18 years of age. The type of alcohol you drink—whether beer, wine, or spirits—does not significantly impact how alcohol raises blood pressure.
Unless your doctor detects your high blood pressure during several visits to their office, you likely won’t know you suffer from this condition. This is why high blood pressure has been referred to as the “silent killer”. Mild hypertension doesn’t present itself with symptoms. You can find more thorough lists of what constitutes a drink if your drink of choice isn’t listed here. Men younger than 65 can drink two drinks a day; men older than 65 can have one drink a day; women of any age can have one drink a day. For primary or essential hypertension, no definite cause can be listed.
In some cases, the healthcare professional might prescribe certain medications to help manage alcohol cessation or hypertension. By implementing these strategies, an individual can manage alcohol consumption. Withdrawal of alcohol reduces blood pressure which leads to weight loss, this also controls hypertension.
While the heart propels oxygen-rich blood, the vessels help to regulate blood pressure and provide pathways for this blood to travel throughout the body.2 If SDs are missing for the change in blood pressure, we will impute the SD, based on information in the same study or from other studies that also have been using ethanol as an intervention to test blood pressure. Change in resting heart rate at the same time intervals as blood pressure outcomes above. Change in early (1 to 6 hours after consumption), intermediate (6 to 12 hours after consumption) and late (13 hours to 26 hours after consumption) resting seated systolic and diastolic blood pressure.
Different types of alcoholic beverages including red wine, white wine, beer, and vodka were used among 32 studies. Stott 1991 included relatively old participants (mean age 81, range 70 to 96 years) compared to the other studies. To assess risk of bias across studies, we rated the evidence as having no limitations, serious limitations, or very serious limitations while taking into account the extent that each trial contributes towards the magnitude of effect (weight) as based on its study sample size and mean difference.
Excessive consumption of alcohol leads to high blood pressure. Cutting off alcohol helps reduce pressure on the heart and permits the blood pressure regulation processes to recover. Different studies show that preventing alcohol improves blood pressure levels. This constriction increases blood pressure. On the other hand, when blood pressure increases, baroreceptors relax the blood vessels to decrease blood pressure.
