Here’s a breakdown of alcohol’s effects on your internal organs and body processes. These effects might not last very long, but that doesn’t make them insignificant. Impulsiveness, loss of coordination, and changes in mood can affect your judgment and behavior and contribute to more far-reaching effects, including accidents, injuries, and decisions you later regret. Dehydration-related effects, like nausea, headache, and dizziness, might not appear for a few hours, and they can also depend on what you drink, how much you drink, and if you also drink water.
- Despite the progress in standardizing measurement of alcohol, studies still vary in how they define the different levels of drinking, such as low-risk or moderate and heavy drinking.
- Alcohol consumption is categorized into different levels based on the amount consumed.
- Over time, drinking can also damage your frontal lobe, the part of the brain responsible for executive functions, like abstract reasoning, decision making, social behavior, and performance.
- In cases of disagreement, the third review authors (JMW) became involved to resolve the disagreement.
- Alcohol can cause both short-term effects, such as lowered inhibitions, and long-term effects, including a weakened immune system.
- One area of interest is how the consumption of alcohol impacts blood pressure.

The studies included participants from the United States, Japan, and South Korea. Completely refraining from consuming alcohol lowers the risk of some of the health risks listed above. Although some of those effects can occur without alcohol consumption, avoiding alcohol helps decrease the risks. Recent data suggest that how does alcohol affect blood pressure moderate and heavy drinking contributes to high blood pressure in men and women. Having higher levels of catecholamines causes the body to excrete less fluid through urine. The Centers for Disease Control and Prevention (CDC) reports a correlation between alcohol consumption and various short- and long-term health risks.

We conducted a standard Chi² test through Review Manager Software 5.3 to test for heterogeneity (Review Manager (RevMan)). A P value of 0.1 or less was considered to show statistically significant heterogeneity. The I² statistic was used to interpret the level of heterogeneity (Higgins 2011). 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.

And if you have a history of high blood pressure, it’s best to avoid alcohol completely or drink only occasionally, and in moderation. According to a 2020 literature review, clinicians are not completely sure why alcohol raises blood pressure. It’s important to note that some studies examined only looked at small numbers of females compared to males.
For example, in one study, the ejection fraction decreased by 4 percent after alcohol consumption (Delgado et al. 1975). Most likely, the decrease in contractility was offset by corresponding decreases in afterload (end-systolic wall stress), systemic vascular resistance, and aortic peak pressure, which maintained cardiac output. Researchers were unable to study in-depth the relationship between age, blood pressure, and alcohol intake. There were risks for misclassifications, and it is possible that some participants changed alcohol consumption amounts during the follow-up time. The study also didn’t look at how different types of alcohol influenced blood pressure. Some data relied on self-reporting; further data could include more diverse samples.
How does alcohol affect my heart?
That’s because alcohol can weaken your immune system, slow healing and make your body more susceptible to infection. But there’s plenty of research to back up the notion that alcohol does lead to weight gain in general. The current paper, which appears in the journal https://ecosoberhouse.com/ Nutrients, aimed to review all current studies dealing with the association between alcohol and blood pressure. Dr. Cho also warns that if you have liver dysfunction or take other medicines that are processed through the liver, your risks might be different.
Proper management of hypertension can lead to reduction in cardiovascular complications and mortality (Kostis 1997; SHEP 1991; Staessen 1999). Investigators have used a variety of noninvasive tests to evaluate the acute effects of alcohol consumption on myocardial function and hemodynamics in healthy humans. As with isolated animal heart experiments, some investigators have found that acute alcohol exposure (blood alcohol levels 40 to 110 mg%) depresses myocardial systolic function in humans (Delgado et al. 1975; Lang et al. 1985; Timmis et al. 1975).
- In Barden 2013, treatment allocation was performed by a statistician who was not involved in the trial.
- Steatotic liver disease develops in about 90% of people who drink more than 1.5 to 2 ounces of alcohol per day.
- When your liver finishes that process, alcohol gets turned into water and carbon dioxide.
- Also, multiple studies have found associations between consumption of alcoholic beverages and specific cancers (Kushi 2012; Seitz 2007).
