We did not identify enough studies to construct a funnel plot for the outcomes under low doses of alcohol. 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 classified six studies as having low risk of is alcoholism considered a disease performance bias (Dai 2002; Narkiewicz 2000; Nishiwaki 2017; Potter 1986; Rosito 1999; Van De Borne 1997). In this study, all test drinks were poured into paper cups to achieve blinding of participants. We contacted the author of Rosito 1999 to request additional information regarding the method of blinding used.
As for the applicability of the available evidence, the full body of data comes from a single study. The behavioural nature of the alcohol intervention necessitated an unmasked study design for the participant and the interventionist in the PATHS 1998 study. Furthermore, participants randomised to the control group were scheduled for data collection visits only. Therefore, despite the efforts to maintain blindness to blood pressure and laboratory data among participants and interventionists, this trial was assessed as having high risk of performance bias.
- The Association has strict policies to prevent these relationships from influencing the science content.
- They may recommend you adjust your dose or switch medications altogether.
- However, current recommendations like those from the Centers for Disease Control and Prevention (CDC) focus on limiting alcohol to one drink a day for women and two drinks a day for men.
- He adds that low blood pressure accompanied by symptoms of shock is considered a medical emergency that requires immediate medical attention.
- The only exception is avoiding circumstances or actions that can lead to it, such as taking recreational drugs or supplements/herbal remedies that can lower your blood pressure.
High blood pressure constitutes one of the leading causes of mortality and morbidity all over the world. At the same time, heavy drinking increases the risk for developing cardiovascular diseases, the honest truth about being sober that no one talks about medium including cardiomyopathy, hypertension, atrial arrhythmias, or stroke. Several studies have already assessed specifically the relationship between alcohol intake and hypertension.
We included one trial (PATHS 1998), where trial participants were randomised to either a cognitive‐behavioural intervention to reduce alcohol intake or no intervention. The specific efficacy and safety of the alcohol dependence treatments is beyond the scope of this systematic review. In this review, we focussed primarily on assessing the potential collateral effects of these interventions linked to a decrease in blood pressure. However, alcohol consumption has been strongly linked to human diseases, including dementia, liver cirrhosis, and neurological conditions. A recent research paper examined whether drinking was related to hypertension, the root factor in morbidity and mortality caused by cardiovascular disease (CVD).
We also contacted Hering 2011, but the study author did not explicitly mention in the email the method of allocation concealment used. Even though these studies reported that participants were randomised to receive alcohol or placebo, the method of randomisation was not mentioned. Although three studies did not report the method of randomisation (Barden 2013; Buckman 2015; Dai 2002), their reported baseline characteristics were well matched.
deLorenzo 1988 published data only
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. For Buckman 2015, blood pressure was recorded beat to beat continuously, but DBP was not reported. Dumont 2010 measured blood pressure during the RCT, but study authors did not provide the before and after measurement of DBP. The aim of Fazio 2004 was to determine effects of alcohol on blood flow volume and velocity. Study authors mentioned that acute ethanol administration caused transitory increase in BP at 20 minutes.
Kelbaek 1987 published data only
This review included only short‐term randomised controlled trials (RCTs) investigating the effects of alcohol on blood pressure and heart rate. Acute alcohol consumption mimics the pattern of social drinking, and evidence indicates that even one glass of an alcoholic drink can increase heart rate. 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.
This assistance is especially beneficial for those who experience low blood pressure due to inactivity or standing up quickly, as well as older adults, says Dr. Stewart. All review authors participated in writing of the Discussion and Conclusions section. Although the original protocol did not state the following rule explicitly, in order to be eligible for inclusion, all studies needed to report data on at least one primary outcome measure.

You might be given a drug that helps your doctor figure out what’s going on. In healthy people, low blood pressure without any symptoms isn’t usually a concern and doesn’t require treatment. But low blood pressure can be a sign of an underlying problem — especially in older people — and could reduce blood flow to the heart, brain, and other vital organs.
On the other hand, Fantin 2016 allowed participants to continue drinking during the period of outcome measurement. These differences in alcohol consumption duration and in outcome measurement times probably contributed to the wide variation in blood pressure in these studies and affected overall results of the meta‐analysis. Hypertension can be genetic or may be due to environmental factors such as poor diet, obesity, tobacco use, excessive alcohol consumption, and sedentary lifestyle (Weber 2014; WHO 2013). A population‐based study showed that the incidence of hypertension is higher in African descendants (36%) than in Caucasians (21%) (Willey 2014). Proper management of hypertension can lead to reduction in cardiovascular complications and mortality (Kostis 1997; SHEP 1991; Staessen 1999).
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. We reviewed available evidence about the short‐term effects of different doses of alcoholic drinks compared to non‐alcoholic drinks on blood pressure and heart rate in adults (≥ ۱۸ years) with both normal and raised blood pressure. The impact of both pharmacological and psychosocial interventions on treating alcohol dependence and withdrawal has been addressed in previous Cochrane systematic reviews and protocols.
What Are the Symptoms of Low Blood Pressure?
He co-founded the Committee on Technology with the California Chapter of the American College of Cardiology, the first state-level chapter of a medical specialty organization with a committee of this type. Dr. Tadwalkar is an emerging voice in his field, cited in a variety of leading health care media. He has been elected to the Super Doctors “Rising Stars” list annually since 2020, an honor bestowed to approximately 2.5% of physicians in a particular state or region. Your health and wellness is unique to you, and the products and services we review may not be right for your circumstances. If you suspect your medication is contributing to your low blood pressure readings, speak with your health care provider before making any changes.
Alcohol and organ damage/CVD
Your doctor might prescribe ACE inhibitors and beta-blockers to help lower your blood pressure. If your heart is severely damaged, your doctor may recommend an implantable defibrillator or pacemaker to help your heart work. They commonly include explainer: what would japanese intervention to boost the weak yen look like fatigue, shortness of breath, and swelling of the legs and feet. 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.
How does alcohol affect blood pressure?
The blood alcohol level decreased over time, and 20‐HETE started to rise (Barden 2013). The hypertensive effect of alcohol after 13 hours of consumption could be the result of the rise in vasoconstrictors and the homeostatic response to restore blood pressure. Plasma renin activity was reported to be increased in Kawano 2000 as a late effect of alcohol consumption. Decreasing or eliminating your alcohol intake can lower your chances of developing high blood pressure. It’s important to have regular physical exams, since hypertension is painless and many people don’t even know they have it. Talk to your healthcare provider to discuss your risk factors and if it is safe for you to drink alcohol, even in moderation.
