Hypertension: How just 1 alcohol drink a day may affect blood pressure

Anticlotting therapies are therefore the cornerstone of managing acute coronary syndromes. Not surprisingly, alcohol consumption has complex and varying effects on platelet function. On the other hand, significant daily alcohol consumption increases platelet aggregation and reactivity. Infection or other stressful events also can lead to immune-triggered platelet production, a condition called rebound thrombocytosis, which may occur immediately after withdrawal from both heavy and one-time heavy (binge) drinking (Numminen et al. 1996).

Where there is substantial and unexplained heterogeneity, we will pool data using the random‐effects model. Where trials compare more than one dose of alcohol, each comparison will be handled separately. Participants in the control group will be divided by the number of groups in order to avoid double counting.

  1. The blood alcohol level decreased over time, and 20‐HETE started to rise (Barden 2013).
  2. We did not consider the lack of blinding of participants as a downgrading factor for certainty of evidence because we do not think that it affected the outcomes of this systematic review.
  3. It is recommended that there should be at least 10 studies reporting each of the subgroups in question (Deeks 2011).
  4. Let’s face it, a hangover in your mid-40s doesn’t feel the same as one in your early 20s.
  5. Other researchers have used genetic approaches (i.e., transgenic animals) to prevent ethanol-induced oxidative stress.

Neurohormonal disruptions may mediate the mechanisms of harm in alcohol consumption. For example, sympathetic activation could underlie the observed BP elevation, as could the disruption of carotid baroreceptor responses that regulate BP. This disruption might be due to higher amounts of endorphins and histamine released by alcohol.

“The best ways to maintain good health and lower blood pressure is by maintaining a healthy weight, exercising regularly, and maintaining a good diet that is low in salt and predominantly made up of unprocessed foods,” Amin said. Alcohol also stimulates the release of adrenaline and puts the body in a fight-or-flight mode, leading to elevated blood pressure. Alcohol also causes damage to the liver over time, especially if you drink too much.

Some evidence suggests that reducing alcohol intake in heavy drinkers could help reduce BP, but much more research is required to validate these observations. Moreover, not only does drinking cause elevated blood pressure, but in excess, it can directly enhance the damage caused to cardiac and renal tissues by hypertension. Some scientists suggest a J-shaped curve between alcohol and CVD, but this remains a hypothesis. Cortisol, plasma renin activity (causing vasoconstriction and sodium and water retention), and impaired endothelial function (inhibiting vasodilatory responses and promoting oxidative stress) have also been reported in heavy drinkers.

Let’s face it, a hangover in your mid-40s doesn’t feel the same as one in your early 20s. While some people develop a tolerance to alcohol over time, this isn’t true for everyone — and this ability doesn’t last forever, Dr. Cho notes. It’s also important to know that the ways in which alcohol affects your heart will vary from person to person, depending on your age and other conditions you may have. But it may be worthwhile learning about what counts as binge drinking and whether or not you may be drinking too much and don’t even know it. And if you have a history of high blood pressure, it’s best to avoid alcohol completely or drink only occasionally, and in moderation.

The sample size in the meta‐analysis for low‐dose comparison was not adequate to assess the effects of low doses of alcohol on BP and HR; however, we believe that the direction of the change in BP and HR was correct. For medium doses and high doses of alcohol, participants represented a range in terms of age, sex, and health condition. Because the participant population comprised predominantly young and healthy normotensive men, the overall evidence generated in this review cannot be extrapolated to women and older populations with other comorbidities. We created a funnel plot using the mean difference (MD) from studies reporting effects of medium doses and high doses of alcohol on SBP, DBP, MAP, and HR against standard error (SE) of the MD to check for the existence of publication bias.

Different mechanisms may be in effect depending on the dose, duration, and pattern of alcohol consumption. More recently, Cosmi and colleagues (2015) examined the effects of daily wine consumption in subjects enrolled in an Italian trial of heart failure patients (mean age ~67), most of whom had reduced ejection-fraction heart failure. Different levels of daily wine consumption (i.e., sometimes, 1 to 2 glasses/day, an overview of outpatient and inpatient detoxification pmc and ≥3 glasses/day) had no effect on fatal or nonfatal outcomes (e.g., hospitalization for a CV event). Subjects who drank wine more often, however, were less likely to have symptoms of depression and more likely to have a better perception of health status. They also had lower levels of circulating inflammatory markers, such as C-terminal proendothelin-1 and pentraxin-3 (Cosmi et al. 2015).

Both the negative and positive effects of alcohol use on particular CV conditions are presented here. The review concludes by suggesting several promising avenues for future research related to alcohol use and CV disease. The magnitude and direction of the effects of alcohol on blood pressure depend on the time after alcohol consumption.

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. One common risk factor for CV disease is the composition of the lipids found in the blood, and the effects of alcohol consumption symptoms of alcohol withdrawal on lipid profiles have been extensively studied. Many researchers have found that alcohol intake increases HDL cholesterol (HDL-c) levels, HDL (“good cholesterol”) particle concentration, apolipoprotein A-I, and HDL-c subfractions (Gardner et al. 2000; Muth et al. 2010; Vu et al. 2016).

However, people who are dependent on alcohol or have been misusing alcohol for a long period of time may have difficulty quitting. Vijaya Musini (VM) contributed to data analysis, interpretation of the final result, and editing of the final draft of the review. James M Wright (JMW) johns hopkins scientists give psychedelics the serious treatment 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. We included adult (≥ 18) participants of both sexes without any restriction on their health condition.
