Alcohols Effects on the Cardiovascular System PMC


how does alcohol affect blood pressure

People over 40 years old or those with a higher risk of hypertension should have a doctor check their blood pressure at least once a year. In a study from 2021, researchers gave 500 mL of orange juice, around 2 cups, daily to people with prehypertension or stage 1 hypertension. A research review from 2022 analyzed studies that gave participants with hypertension 70–250 milliliters (mL) of beetroot juice per day for 3–60 days. Since the kidneys excrete a tenth of ingested alcohol, toxicity in these organs is expected, which could enhance inflammation and renal damage in hypertensive patients.

  • Heavy drinking can also lead to a host of health concerns, like brain damage, heart disease, cirrhosis of the liver and even certain kinds of cancer.
  • Both reviewers (ST and CT) rated the certainty of evidence independently by examining risk of bias, indirectness, inconsistency, imprecision, and publication bias.
  • Oxidative stress is an imbalance between production of free radicals and the body’s ability to detoxify or fight off their harmful effects through neutralization by antioxidants.
  • Anticlotting therapies are therefore the cornerstone of managing acute coronary syndromes.
  • Healthcare professionals may recommend people with hypertension decrease the amount of alcohol they consume.
  • Because alcohol and cholesterol medicine both are processed through your liver, they are, in a sense, competing for clearance.

Regularly consuming too many calories can lead to weight gain and therefore obesity, which is a risk factor for heart attack, stroke and type 2 diabetes. When you stop drinking, or reduce the amount you drink, you’ll see rapid improvement in your blood pressure (you should see a reduction within a few days). A person should speak to their doctor if they have concerns about their blood pressure or alcohol intake. A study from 2023 found that tea consumption could help reduce a person’s risk of hypertension by 10%. Researchers noted this effect varied depending on the type of tea a person drank.

Aren’t there some benefits to drinking alcohol?

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. Some people may be able to continue to drink alcohol in low amounts if they have high blood pressure. There is no singular recommended level of alcohol for people who have high blood pressure aside from reducing your intake as much as possible.

  • This systematic review searched only the MEDLINE database for relevant studies, hence it was not exhaustive.
  • According to a recent analysis by the American Heart Association (AHA), the more alcoholic drinks you have each day, the higher your systolic blood pressure tends to be.
  • A 2018 study, echoed by the World Health Organization (WHO), concluded that no amount of alcohol is safe for consumption, as alcohol leads to a loss of healthy life.
  • Because women could be affected differently by alcohol than men, future RCTs in women are needed.

The short-term effects of alcohol (headache, nausea, you know the rest) are easy to pinpoint. But there are ways that alcohol affects your body over time that are important to understand. One of the long-term effects of alcohol on your heart is alcoholic cardiomyopathy. This is when your heart-pumping function gets weaker and your heart gets larger due to changes from heavy alcohol use over a long period of time.

What are the age-related risk factors of alcohol on blood pressure?

High alcohol consumption also increased heart rate from 7 to 12 hours and after 13 hours. 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). We are aware of one systematic review on effects of alcohol on blood pressure that was published in 2005 (McFadden 2005). McFadden 2005 included both randomised and non‐randomised studies with a minimum of 24 hours of blood pressure observation after alcohol consumption. This systematic review searched only the MEDLINE database for relevant studies, hence it was not exhaustive.

Drinking frequently or binging on a large amount of alcohol in a small period of time can lead to health problems. “This complex interplay leads to elevated blood pressure and subsequent hypertension,” Ramnauth said. However, “since everyone has different physiology, many people may react to the same amount of alcohol in diverse ways,” he added. It is important to note that 2 out of 19 studies were single‐blinded (Agewall 2000; Karatzi 2013). Personnel were blinded instead of participants in Karatzi 2013, and neither personnel nor participants were blinded in Agewall 2000, so we assessed these studies as having high risk of bias. We contacted the study authors for missing or unclear information relevant to the review using contact information provided in their respective articles.

The magnitude of the effects of alcohol on blood pressure and heart rate varies, based possibly on genetic factors and on the amount of alcohol consumed. We classified nine studies as having high risk of bias (Agewall 2000; Bau 2011; Buckman 2015; Dumont 2010; Fazio 2004; Karatzi 2013; Maufrais 2017; Rossinen 1997; Van De Borne 1997). Agewall 2000 measured blood pressure upon participants’ arrival and did not measure blood pressure after the intervention. The aim of Bau 2011 was to determine the effects of alcohol on heart rate variability, so study authors did not measure and report DBP.

Nevertheless, there is much evidence that the moderate consumption of alcohol is beneficial for cardiovascular health, beginning from the “French Paradox” – the finding of reduced ischemic heart disease (IHD) among those who regularly drink red https://ecosoberhouse.com/ wine. You should never consider wine or any other alcohol as a way to lower your heart disease risk. And, in fact, the study also showed that drinking one or fewer drinks per day was related to the lowest likelihood of dying from a stroke.

  • Last, we attempted to explore the reason for heterogeneity by looking for clinical and methodological differences between trials.
  • The study author explained the blinding method in detail in an email, so we classified this study as having low risk of bias.
  • That’s partly why people who drink may find that although they’re consuming the same amount they always have, they feel the effects more quickly or strongly — that’s especially true for older women, according to the National Institute on Aging.

Various studies with animals and humans indicate that ethanol can increase the development of reactive oxygen species (ROS), leading to increases in redox-signaling pathways and decreases in protective antioxidant levels. Alcohol also can increase levels of co-enzymes or reducing equivalents (e.g., reduced nicotinamide adenine dinucleotide phosphate [NADPH]), which lead to increases in ROS formation and decreases in eNOS activity (Ceron et al. 2014). Several excellent reviews offer more detailed assessments of vascular cellular how does alcohol affect blood pressure mechanisms (Cahill and Redmond 2012; Husain et al. 2014; Marchi et al. 2014; Toda and Ayajiki 2010). Results from another meta-analysis of 12 cohort studies found a similar dose–response relationship between alcohol consumption and HTN for males. A J-shaped relationship for females showed protective effects at or below consumption levels of 15 g/day (Taylor et al. 2009). These data highlight how gender may be an important modifier of the alcohol threshold level and can shape the alcohol benefit–risk relationship.

When your liver finishes that process, alcohol gets turned into water and carbon dioxide. And that’s on top of the toll that alcohol use can take on relationships, not to mention the potential for financial strain and legal troubles.
