For comparison purposes, participants who had received medical information that at some point in their life they had hypertension were excluded. The results found were similar to those found in the present study, with a small reduction in power due to the sample size, mainly in the most frequent consumption categories. Odds ratio for high systemic blood pressure according to the pattern of alcohol consumption. Odds ratio for elevated systemic blood pressure according to alcohol consumption.
The frequency of binge drinking in this study (25,3%) was close to values estimated by WHO (22%) . However, it was higher than the values found in the National Survey of Health 2013 (13.7%) and in a Brazilian survey obtained by phone calls (VIGITEL 2014;16.5%) . This fact may be due to the differences between the survey methodologies.
Will Quitting Alcohol Lower Blood Pressure?
We conducted a standard Chi² test through Review Manager Software 5.3 to test for heterogeneity (Review Manager ). A P value of 0.1 or less was considered to show statistically significant heterogeneity. For the purposes of this review, if how does alcohol affect your blood pressure 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.
This effect, combined with the increased effects of blood pressure medicine, can lead to drops in blood pressure that can cause dizziness or even make you pass out. Alcohol is difficult for the body to process and adds stress to the liver. The liver must divert its resources to metabolizing alcohol, making it process other medicines more slowly.

Participants reported their drinking behavior on several questionnaires administered by mail and in person.
Brown 1981 published data only
We classified the remaining 33 studies as having low risk of bias because heart rate was measured and reported. We classified seven studies as having unclear risk of performance bias (Bau 2005; Bau 2011; Cheyne 2004; Dumont 2010; Karatzi 2005; Mahmud 2002; Maule 1993). Bau 2005 and Bau 2011 mentioned only that investigators and volunteers were blinded to the content of the drink but did not mention the method of blinding used in these studies.
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. In the case of performance bias, we classified six studies as having low risk of bias, 19 studies as having high risk of bias, and seven studies as having unclear risk of https://ecosoberhouse.com/ bias. We calculated and reported mean difference , with corresponding 95% confidence interval (95% CI). This article is an update of “Effect of alcohol on blood pressure” in volume 2017, CD012787. The current paper, which appears in the journal Nutrients, aimed to review all current studies dealing with the association between alcohol and blood pressure.
