All studies included an independent individual who was blinded to control and test groups to evaluate and analyse the data. One study ‐ Nishiwaki 2017 (a single‐blinded study) ‐ ensured participant blinding but not blinding of outcome assessors. Karatzi 2005, Mahmud 2002, Maule 1993, and Potter 1986 did not mention the method of blinding of outcome assessors. 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. For low doses of alcohol, we found that one glass of alcohol had little to no effect on blood pressure and increased heart rate within six hours of drinking. High blood sugar and high levels of “bad” non-HDL cholesterol raise the risk of heart disease.
Drinks to avoid with high blood pressure
Most experts agree, though, that does not show a significant enough drop to advise drinking for an entire population. In the U.S., about 75 million adults have high blood pressure (or 1 in every 3 Americans) and it accounts for an estimated 54% of all strokes and 47% of all ischemic (reduced blood flow) heart disease events.1,2 Alcohol use can contribute to high blood pressure. In humans, endothelial function is assessed by measuring the widening (i.e., dilation) of the brachial artery under different conditions.
- The Centers for Disease Control and Prevention (CDC) notes that if a person has hypertension, they may have a higher risk of conditions such as heart attack, stroke, and heart disease.
- It also discusses treatment and some frequently asked questions about alcohol and high blood pressure.
- This is because your age plays a factor in how well you tolerate alcohol.

Routinely drinking alcohol may raise blood pressure even in adults without hypertension
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. Review authors included nine studies involving a total of 119 participants, and the duration of these studies was between four and seven days. Participants in those studies consumed alcohol regularly during the study period, whereas https://ecosoberhouse.com/ in our systematic review, we included only studies in which participants consumed alcohol for a short period. Based on nine studies, McFadden 2005 reported that the mean increase in SBP was 2.7 mmHg and in DBP was 1.4 mmHg. Only three of these studies measured BP at various time points and found that alcohol has a hypotensive effect lasting up to five hours after alcohol consumption and a hypertensive effect 20 hours after alcohol consumption that lasts until the next day.
What are the age-related risk factors of alcohol on blood pressure?
Whelton is also the chair of the American Heart Association’s 2017 Hypertension Practice Guidelines and a member of the writing committee for the Association’s 2021 Scientific Statement on Management of Stage 1 Hypertension in Adults. Other researchers have used genetic approaches (i.e., transgenic animals) to prevent ethanol-induced oxidative stress. One approach included overexpression of proteins such as insulin-like growth factor (IGF-1), which stimulates growth and cell proliferation and has antiapoptotic effects (see Zhang et al. 2014). In contrast to control mice, the IGF-1–expressing animals exhibited no evidence of changes in expression of antioxidant enzymes (i.e., superoxide dismutase-1) or any decreases in contractile function after 16 weeks of ethanol consumption. The findings suggest a protective effect of overexpression of IGF-1 in the transgenic animals (Zhang et al. 2014). Some investigators have suggested that drinking wine may offer more protection against CV disease because it contains polyphenols, such as resveratrol and flavonoids, which are micronutrients with antioxidant activity (Tangney and Rasmussen 2013).
Characteristics of studies
It’s important to keep exercising to keep blood pressure from rising again. As a general goal, aim for at least 30 minutes of moderate physical activity every day. Carrying too much weight around the waist can raise the risk of high blood pressure. If you’re overweight or have obesity, losing even a small amount of weight can help lower blood pressure.
To Drink or Not to Drink: High Blood Pressure and Alcohol
Dysfunctional mitochondria are less efficient, can become a source of ROS, and are more likely to initiate apoptosis (Marzetti et al. 2013). Alcohol consumption increases the amount of calcium that binds to the blood vessels. This increases the sensitivity of the blood vessels to compounds that constrict them.
Treating Alcohol-Related Hypertension
- Data from animal models and human beings with a history of long-term drinking suggest that oxidative stress may be an early and initiating mechanism.
- When the SNS gets activated by alcohol, it can increase heart rates and constrict blood vessels.
- The women’s metabolic measurements were then taken over the next 6 hours.
- The Cochrane Hypertension Information Specialist searched the following databases without language, publication year, or publication status restrictions.
Your doctor will often advise you when it’s safe to start drinking alcohol again, from a medical perspective. Psychologically, however, many people feel low in mood after they’re discharged home, especially following open heart how does alcohol affect high blood pressure surgery. In hospital, your medications are adjusted to control your blood pressure, but you aren’t drinking alcohol at that time.
Moreover, none of the studies reported male and female data separately. As a result, we were not able to quantify the magnitude of the effects of alcohol on men and women separately. This is unfortunate, as we have reason to believe that the effects of alcohol on BP might be greater in women. We are moderately certain that medium‐dose alcohol decreased blood pressure and increased heart rate within six hours of consumption. We did not see any significant change in blood pressure or heart rate after that, but the evidence was limited. Drinking excessive alcohol is considered one of the most common causes of raised blood pressure.
Can I still drink alcohol with high blood pressure?
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. When necessary, we contacted the authors of studies for information about unclear study design. All extracted data were entered and double‐checked in RevMan 5.3 software (Review Manager (RevMan)). Several clinical trials in humans and studies conducted in animal models have reported stimulation of the sympathetic nervous system and increased noradrenaline after consumption of alcohol (Barden 2013; Grassi 1989; Randin 1995; Russ 1991; Zhang 1989).
Internal sources
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. If the dose of a study was not reported in the article and the study author did not respond to our request, we excluded that study. Heavy alcohol users who cut back to average drinking can lower their top number in a blood pressure reading by about 5.5 millimeters of mercury (mm Hg) and their bottom number by about 4 mm Hg.
