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. Based on nine studies, McFadden 2005 reported that the mean increase in SBP was 2.7 mmHg and in DBP was 1.4 mmHg.
Effects of alcohol withdrawal on blood pressure in hypertensive heavy drinkers
Given its spectrum of manifestations from mild to severe and potentially fatal, all healthcare team members must recognize the signs and symptoms of this condition. Timely assessment and accurate treatment are vital to preventing disease progression. Comprehensive patient care entails acute management and outpatient support in the hospital setting. In the inpatient setting, nurses perform frequent assessments that inform the treatment plan. We planned on conducting sensitivity analyses on studies based on their level of risk of bias (high‐risk studies versus low‐risk studies). Most of the included studies had similar risk of bias across all domains except for performance bias and detection bias, for which risk arises from blinding of participants, personnel, and outcome assessors.

Still, if you’re experiencing withdrawal symptoms, it’s essential to get evaluated by a healthcare professional. Depending on the severity of your symptoms, your doctor may recommend monitoring a medical setting or at home. A doctor may also prescribe a sedative drug, such as a benzodiazepine, to help reduce withdrawal symptoms such as restlessness or agitation. Benzodiazepines like Librium (chlordiazepoxide) and Ativan (lorazepam) may also help to prevent minor withdrawal symptoms from becoming more severe. Other drugs a healthcare provider might prescribe include anxiolytics , vitamins, and suboxone. In addition to experiencing Stage 2 symptoms, those with severe alcohol withdrawal experience severe anxiety and moderate to severe tremors.
Description of studies
Additionally, although all types of available studies are included in the review, there is unfortunately a paucity of data from randomized controlled clinical trials on this topic. According to the published protocol, we intended to include only double‐blind RCTs in this review. Because https://ecosoberhouse.com/ higher doses of alcohol exert specific pharmacological effects on drinkers, we had a few double‐blind RCTs after the first screening. Considering the difficulty of masking in these types of studies, we decided to also include single‐blind and open‐label studies in the review.
- There are many resources available for anyone who is ready to stop drinking for good, or who wants to reduce the harm alcohol is causing in their life by cutting down.
- Accordingly, we considered up to 14 g of alcohol as a low dose of alcohol.
- They will be able to monitor your vital signs and help you through the process in the safest way possible.
- But if you drink alone, or down multiple drinks a day, it could turn into an unhealthy habit.
- Previous studies reported that women are affected more than men after drinking the same amount of alcohol because of their lower body weight and higher body fat.
At the same time, endogenous GABA is downregulated.[3] Thus, when alcohol is withdrawn, a relative deficit of GABA may occur and simultaneous excess in glutamate, resulting in the excitatory symptoms seen in alcohol withdrawal syndrome. The alcohol withdrawal timeline varies, but the worst of the symptoms typically wear off after 72 hours. People who are daily or heavy drinkers may need medical support to quit.
Second, lack of representation of the female population was notable in the included studies. Only four studies included almost equal numbers of male and female participants (Buckman 2015; Foppa 2002; Maufrais 2017; Zeichner 1985). Moreover, none of the studies reported male and female data separately.

This syndrome can further progress to severe manifestations, such as alcohol withdrawal delirium, which poses significant diagnostic and management challenges. Mild symptoms may progress to alcohol hallucinosis, characterized by visual or auditory hallucinations that usually subside within 48 hours after alcohol cessation. Withdrawal seizures can occur in patients within just a few hours of alcohol cessation. For this reason, there have been many attempts to classify symptoms of AWS either by severity or time of onset to facilitate prediction and outcome. In early stages, symptoms usually are restricted to autonomic presentations, tremor, hyperactivity, insomnia, and headache. In minor withdrawal, patients always have intact orientation and are fully conscious.
- Keep in mind that alcohol contains calories and may cause weight gain.
- The blood alcohol level decreased over time, and 20‐HETE started to rise (Barden 2013).
- This is unfortunate, as we have reason to believe that the effects of alcohol on BP might be greater in women.
- So, treatment may also include electrolyte corrections and multivitamin fluids.
Does drinking alcohol affect blood pressure?
- Karatzi 2005 mentioned the method of blinding of participants, but it is not clear whether involved personnel were blinded as well.
- The I² statistic was used to interpret the level of heterogeneity (Higgins 2011).
- We classified seven studies as having high risk of bias (Agewall 2000; Bau 2011; Dumont 2010; Fazio 2004; Karatzi 2013; Maufrais 2017; Van De Borne 1997).
- James M Wright (JMW) formulated the idea, developed the basis of the protocol, and contributed to data analysis, interpretation of the final result, and editing of the final draft of the review.
- Withdrawal is different for everyone; there really is no “normal” and it can be hard to predict an individual person’s experience.
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. The inclusion of non‐randomised studies in McFadden 2005, which are known to be at higher risk of bias, is likely the reason for the discrepancy in the magnitude of BP effects. While it is unclear why some people experience greater withdrawal symptoms than others, there is evidence for genetic predisposition.3 A key vital sign often affected in alcohol withdrawal is blood pressure. An elevation in blood pressure can also worsen to the level of hypertensive urgency or emergency.
- It’s important first to get evaluated by a medical professional and to reach out to a support system if you’re able.
- Others experiencing more severe symptoms may require hospitalization to avoid life threatening conditions.
- When using any dosing technique, it is important to recognize the symptoms of benzodiazepine toxicity that can include respiratory depression, excessive sedation, ataxia, confusion, memory impairment, and delirium, which may be difficult to differentiate from DT .
- Delirium tremens can last up to 5 days, with a mortality rate of up to 37%.
Screening and assessment tools do not allow physicians to predict with confidence who will or will not experience life-threatening symptoms. Those experiencing mild alcohol withdrawal symptoms or who are concerned about experiencing withdrawal symptoms will benefit from the advice of a physician or clinician trained to can alcohol lower blood pressure assess and treat patients in alcohol withdrawal. Moderate drinking is officially defined as 1 drink or less per day for women and 2 drinks or less per day for men. However, if a person already has alcohol use disorder, they can help prevent some of the withdrawal symptoms by speaking to a doctor about safe withdrawal.

Hypertensive emergency describes a significantly elevated blood pressure with signs or symptoms of acute, ongoing target organ damage. Given concern that an excessive hypotensive response could lead to ischemic complications, in those who are asymptomatic, slower reductions in blood pressure may be achieved with one of the oral agents described previously, such as clonidine. 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.
