High‐dose alcohol decreased SBP by 3.49 mmHg within the first six hours, and by 3.77 mmHg between 7 and 12 hours after consumption. After 13 hours, high doses of alcohol increased SBP by 3.7 mmHg compared to placebo. DBP was not significantly affected up to 12 hours after drinking a high dose of alcohol, but there was a statistically significant increase in DBP during the ≥ 13 hour time interval after alcohol consumption.

What effects does alcohol have on mental health?
Alcohol stimulates the release of endothelin 1 and 2 from vascular endothelium in a dose dependent manner[81]. Alcohol also increases the angiotensin II levels does alcohol affect bp in the blood and vessels[62,63]. Endothelin 1 and 2 as well as angiotensin II are known to be potent vasoconstrictors of the blood vessels[63,81].
- A doctor may recommend a person with hypertension not to consume energy drinks.
- Furthermore, we contacted authors of included studies to obtain all relevant data when information was insufficient or missing.
- Alcohol also increases the angiotensin II levels in the blood and vessels[62,63].
- There were risks for misclassifications, and it is possible that some participants changed alcohol consumption amounts during the follow-up time.
For the purposes of this review, if I² was greater than 50%, it was considered to show a substantial level of heterogeneity. Furthermore, we visually inspected the forest plot to check whether there were any non‐overlapping confidence intervals indicating heterogeneity. Last, we attempted to explore the reason for heterogeneity by looking for clinical and methodological differences between trials. All outcomes of interest in the review (BP and HR) produced continuous data. We calculated and reported mean difference (MD), with corresponding 95% confidence interval (95% CI). Discuss your alcohol intake with your healthcare provider and make lifestyle changes as recommended.
Tuomilehto 1984 published data only
Common findings in alcohol studies from the 1970s and early 1980s included decreases in mitochondrial indices that reflected mitochondrial state III respiration, or ADP-stimulated respiration (Pachinger et al. 1973; Segel et al. 1981; Williams and Li 1977). In cardiomyocyte mitochondria as well as other mitochondrial types, such imbalances could lead to further decreases in cellular respiration and oxidative phosphorylation. Evidence of oxidative stress is found after short periods of alcohol consumption (2 to 18 weeks), at least in animal models.
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. 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 in our systematic review, we included only studies in which participants consumed alcohol for a short period.
Reduce your risk of hypertension
However, further research indicates alcohol can actually cause hypertension. For example, some people who are on cholesterol-lowering medicines may experience muscle aches when they drink alcohol. Because alcohol and cholesterol medicine both are processed through your liver, they are, in a sense, competing for clearance. So, it’s important to think about your overall health and talk to a healthcare provider about your personal risk factors. 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.
- Also, multiple studies have found associations between consumption of alcoholic beverages and specific cancers (Kushi 2012; Seitz 2007).
- If you drink alcohol, limit consumption to no more than two drinks per day for men and one drink per day for women.
- The short-term effects of alcohol (headache, nausea, you know the rest) are easy to pinpoint.
- 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).
- Both ST and CT independently assessed studies for inclusion or exclusion and assessed the risk of bias of all included studies.
Although some of those effects can occur without alcohol consumption, avoiding alcohol helps decrease the risks. Recent data suggest that moderate and heavy drinking contributes to high blood pressure in men and women. This combination of higher fluid levels in the body and smaller blood vessels increases blood pressure.
