Does Alcohol Lower Blood Pressure
Can alcohol lower blood pressure? This may seem unlikely but, it has been confirmed that moderate intake is deemed beneficial. Does alcohol lower blood pressure temporarily? It is possible to lower pressure by 2 to 4mm Hg, but this means low quantities.
The key is the term moderate:
- Men under retirement age two drinks per day
- Men over retirement age one drink per day
- Women irrespective of age one drink per day
Research indicates that the risk of coronary heart disease lessens when moderate levels of drink are consumed. An individual with hypertension can rapidly reverse the condition through stopping drinking. Alcoholism plays a factor in this. Consider the impact of alcohol withdrawal and blood pressure and the results are encouraging. By gradually withdrawing from this addictive substance, hypertension may be helped.
Just 1 Drink A Day May Increase High Blood Pressure Risk
Moderate alcohol consumption is thought to be heart healthy, but a new study suggests that the truth is more complicated.
Drinking alcohol, even in moderation, may increase your risk of developing high blood pressure, say researchers.
Yes, this is the same moderate that weve been told many times before is heart healthy.
While earlier research has suggested that light and moderate alcohol consumption reduces the risk of dying from cardiovascular disease, a new study has a different finding.
This study certainly adds a twist to the notion that moderate alcohol consumption is beneficial for cardiovascular health, said Dr. Gregory Marcus, director of clinical research, Division of Cardiology, at the University of California, San Francisco, who was not involved in the study.
National Health and Nutrition Examination Survey between 1988 and 1994.
People in the study reported their drinking behavior on several questionnaires. Study staff also measured participants blood pressure at home or at a mobile examination center.
Researchers studied over 17,000 people and found those who consumed 7 to 13 drinks of alcohol per week were 53 percent more likely to have stage 1 hypertension, compared to nondrinkers.
Heavy drinkers more than 14 drinks per week were 69 percent more likely to have stage 1 hypertension than nondrinkers. One standard drink contains about 0.6 fluid ounces of pure alcohol.
Guidelines For Drinking Alcohol If You Have High Blood Pressure Or Are At Risk Of Developing It
If you have high blood pressure or are at risk of developing it, it would be best to avoid alcohol entirely or drink it in very moderate amounts. For healthy people, moderate translates to one or two drinks a day, no matter the type of alcohol.
There are different definitions of excessive drinking that can help you understand various types of alcohol consumption:
-
Binge-drinking: having four or more drinks for women and five or more drinks for men in a single occasion
-
Moderate drinking: less than or up to two drinks a day for men and one drink for women
-
Heavy drinking: more than 15 drinks per week for men and eight drinks per week for women
According to a large-scale study with more than 17,000 participants, those categorized as moderate or heavy drinkers were at a higher risk for high blood pressure than those who didnt drink alcohol.
In another study, binge drinking was more likely to increase systolic blood pressure.
If you take high blood pressure medication, you should be especially cautious of consuming alcohol. Certain types of hypertension medication, such as alpha-blockers, beta-blockers, and nitrates, can have dangerous interactions with alcohol.

Data Collection And Analysis
Two review authors independently extracted data and assessed the quality of included studies. We also contacted trial authors for missing or unclear information. Mean difference from placebo with 95% confidence interval was the outcome measure, and a fixedeffect model was used to combine effect sizes across studies.
How Alcohol Affects Blood Pressure
There are many ways alcohol is known to indirectly affect blood pressure. These include:
- Nervous system changes: Medical scientists do not fully understand how alcohols effect on the nervous system influences blood pressure. However, alcohol is known to affect the nervous system, and the nervous system plays a role in controlling blood pressure.
- Changes in pressure receptors: Receptors in the body called baroreceptors sense blood pressure levels and make any needed adjustments. Alcohol affects these receptors, making blood pressure higher.
- Increased cortisol: Cortisol is a stress hormone that raises blood pressure. Alcohol increases the amount of cortisol, increasing blood pressure.
- Increased calcium levels: Alcohol increases the amount of calcium in the muscles that line arteries. This causes arteries to become more constricted, elevating blood pressure.
- Increase in vasoconstrictor hormones: There are a number of hormones that cause arteries to constrict. Scientists have found that alcohol interacts with these hormones to increase blood pressure by constricting arteries and retaining fluid filtered in the kidneys.
- Weight effects: Being overweight is known to increase blood pressure. The empty calories in alcohol lead to weight gain over the long term, further increasing blood pressure.
There is no single factor that makes blood pressure increase from alcohol use. Rather, it is a combination of factors that work together to create high blood pressure.

Overall Completeness And Applicability Of Evidence
The evidence synthesised in this review was collected from 32 RCTs in 767 participants. Of the 32 studies, two studied lowdose alcohol, 12 studied mediumdose alcohol, and 19 studied highdose alcohol. studied both medium and high doses of alcohol. The sample size in the metaanalysis for lowdose 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.

So What Effect Does Alcohol Have On Blood Pressure
One of the primary ways you can help prevent the negative health impacts of hypertension is by understanding the way common substances like alcohol affect your blood pressure. You read that correctly consuming alcohol can increase your blood pressure.
How do you minimize the risk of hypertension without cutting out alcohol entirely? If you drink alcohol, such as red wine, do so in moderation.
Per the American Heart Association, heavy and regular use of alcohol can increase blood pressure which can produce irregular heartbeats and lead to heart failure.
Too much alcohol can also contribute to high triglycerides which cause fatty buildup in the artery walls, increasing your risk of a heart attack and stroke.
If thats not enough reason to consider limiting alcohol consumption to recommended intake levels, consuming higher amounts of alcohol can also lead to cancer, obesity, alcoholism, suicide and accidents.

Alcohol And Blood Pressure
A 2018 study, echoed by the World Health Organization , concluded that no amount of alcohol is safe for consumption, as alcohol leads to a loss of healthy life. Drinking frequently or binging on a large amount of alcohol in a small period of time can lead to health problems.
Drinking alcohol may also increase blood pressure for a short amount of time even in healthy people. If you drink too much over time, chronic hypertension can develop.
Hypertension leads to an increased risk of other health problems, including stroke, heart attack, and heart disease.
How Alcohol Interacts With Ccbs Like Amlodipine And Verapamil
Calcium channel blockers are another group of antihypertensives. They are split into two sub-groups: dihydropyridines and nondihydropyridines. Dihydropyridine CCBs are more commonly used and include medications like . Nondihydropyridine CCBs, such as and , are usually prescribed if you have both high blood pressure and heart rhythm problems.
Alcohols effects on dihydropyridine CCBs havent been studied too much when it comes to treating high blood pressure. Most of the research available discusses whether these medications can be used when treating alcohol withdrawals, but none are conclusive. Its best to limit your drinking while taking medications like amlodipine to prevent possible dizziness and passing out.
Nondihydropyridine CCBs, on the other hand, are known to have a direct interaction with alcohol. If you drink while taking either verapamil or diltiazem, your body takes longer to digest and remove the alcohol from your bloodstream. This means each drink has a more potent effect than it would for people not taking these medications. You are likely to feel drunk longer and may potentially be at a higher risk for alcohol poisoning.

How Does Alcohol Affect My Blood Pressure
Though scientists are still learning exactly how it happens, we do know that alcohol can raise your blood pressure directly and indirectly.
The direct effects of alcohol on blood pressure are related to the way alcohol is processed through your body. Having more than 3 drinks at once can temporarily raise your blood pressure, but once the alcohol is processed out of your body, blood pressure usually returns to normal. Similarly, binge drinkinghaving 5 or more drinks in 2 hours for men and 4 or more drinks in 2 hours for womencan cause a temporary spike in blood pressure. But if binge drinking turns into long-term excess, it may lead to chronic hypertension .
What about the indirect effects of alcohol on blood pressure? Alcohol contains lots of calories and sugars which contribute to increased body fat, weight gain, and poor diet. All of these factors can lead to high blood pressure.
Heavy drinkersbinge drinking at least 5 days in one monthare more likely to experience the direct and indirect effects of alcohol on blood pressure compared to moderate drinkers. To improve blood pressure, its worthwhile for heavy drinkers to gradually reduce their intake by 1 to 2 servings of alcohol per day until they are drinking no more than 1 to 2 servings total per day. This would be considered moderate drinking.
Heart Diseases That Can Result From Alcohol Abuse
The heart conditions discussed in the above section can all increase a persons risk of a number of different heart diseases. Regular alcohol abuse can significantly increase the risk of high blood pressure, irregular heartbeat, and weakened heart muscles, all of which can lead to heart disease.
Heart diseases that may develop as a result of alcohol abuse include:
- Heart Attack Regular alcohol consumption can increase fat levels in the blood. This, in turn, can result in high levels of bad cholesterol. Excess levels of bad cholesterol can clog the arteries of the heart, which may eventually result in clots that can cause a heart attack.
- Stroke Alcohol abuse can increase a persons risk of both ischemic stroke and hemorrhagic stroke. Ischemic stroke occurs when the artery that supplies blood to the brain becomes blocked. A hemorrhagic stroke happens when the artery that supplies blood to the brain tissues bleeds or tears. Both types of stroke can occur as a direct result of alcohol abuse.
- Heart Failure Studies have shown that excessive alcohol consumption is linked to an increased risk of heart failure. Individuals who have 14 or more drinks a week are up to 10 percent more likely to experience heart failure, while people who have 21 or more drinks per week experience heart failure up 48 percent more than nondrinkers.

Advice For Healthy People
The Australian Guidelines say: To reduce the risk of harm from alcohol-related disease or injury, healthy men and women should have no more than 10 standard drinks a week and no more than 4 standard drinks on any one day.
The less you drink, the lower your risk of harm from alcohol.
The Guidelines are for healthy people. Talk with your doctor about what is safe for you.
Does Alcohol Protect Against Heart Problems
Some studies have shown an association between moderate alcohol intake and a lower risk of dying from heart disease.
But its hard to determine cause and effect from those studies, says McEvoy. Perhaps people who sip red wine have higher incomes, which tend to be associated with more education and greater access to healthier foods. Similarly, red wine drinkers might be more likely to eat a heart-healthy diet.
There is some evidence that moderate amounts of alcohol might help to slightly raise levels of good HDL cholesterol. Researchers have also suggested that red wine, in particular, might protect the heart, thanks to the antioxidants it contains.
But you dont have to pop a cork to reap those benefits. Exercise can also boost HDL cholesterol levels, and antioxidants can be found in other foods, such as fruits, vegetables and grape juice

How Does Alcohol Cause Hypertension
Alcohol increases blood levels of the hormone renin, which causes the blood vessels to constrict. This means that they get smaller in diameter. Renin also decreases how much fluid the body eliminates as urine. This combination of higher fluid levels in the body and smaller blood vessels increases blood pressure .
Wine And Blood Pressure
While red wine has been touted to have many heart health benefits, lowering blood pressure is not one of them. Treat red and white wine equaling when it comes to blood pressure. If you have high blood pressure, consume wine in moderation.
If your blood pressure is not in control, I recommend you eliminate alcohol completely until your blood pressure is well-managed.
Researchers in Spain did find high blood pressure benefits were connected to drinking non-alcoholic red wine. Extra emphasis on the NON-ALCOHOLIC part.

With High Blood Pressure Light To Moderate Drinking May Protect Heart
By Kathryn Doyle, Reuters Health

NEW YORK Drinking alcohol has been tied in the past to a higher risk of high blood pressure, but in a new analysis of past studies, researchers found that a drink or two a day seemed to protect even those with hypertension from heart disease and death.
People with high blood pressure who have never been drinkers shouldnt start now based on the evidence from studies like these, said senior author Qi-Qiang He of the School of Public Health/Global Health Institute at Wuhan University in China.
Observational studies only include data on what people do in their lives and what happens to them, and cant say for sure that one action, like drinking alcohol, causes a particular result.
The new meta-analysis combines the data from nine previous studies involving a total of nearly 400,000 people with high blood pressure. In all of the studies, alcohol consumption, including wine, beer and spirits, was recorded, as were cases of heart disease, stroke, heart failure and death from any cause.
The researchers divided the participants into four groups: occasional or never drinkers, those who drank about 10 grams of ethanol – pure alcohol – per day, and those who drank 20 or 30 grams of ethanol per day.
In the U.S., a five-ounce glass of wine, a 12-ounce bottle of beer and a 1.5-ounce shot of liquor each contain about 14 grams of alcohol.
This was firstly found true in people with normal blood pressure, He told Reuters Health by email.
It Remains Somewhat Of A Mystery
The National Institute on Alcohol Abuse and Alcoholism indicate a couple of feasible triggers for the link between alcohol consumption and high blood pressure.
To begin with, the existence of alcohol in the bloodstream might result in the production of fight/flight hormones. These chemicals make your blood vessels constricted or tighten. Conversely, the existence of alcohol might overstimulate the small tendons that line blood vessel walls and assist to preserve the regular healthy flow.

I Have High Blood Pressure Can I Still Drink Wine
Q: I have high blood pressure. Can I still drink wine?
A: High blood pressure, or hypertension, refers to a condition in which blood is pumped through the circulatory system at a force that could potentially damage the heart. Because several different factors, from genetics to lifestyle habits, can cause high blood pressure, you should consult a physician before making any change in your diet and alcohol consumption.
Having said that, researchers at the School of Public Health at Wuhan University in China recently conducted a meta-analysis of nine previous studies that address the relationship between alcohol and high blood pressure. Their analysis looked at data from more than 400,000 individuals, categorizing them into four groups based on their volume of alcohol consumption. Overall, the risk for heart problems was lower for those who drank more alcohol. The authors of that paper concluded that among those who have hypertension, drinking low-to-moderate amounts of alcohol seems to reduce the risk of developing cardiovascular disease or of all-cause mortality.
Other studies, however, have found that alcohol consumption, especially binge drinking, raises blood pressure temporarily, and chronic binge drinking may lead to longterm problems with hypertension. Much of this research, however, has not distinguished wine from other forms of alcohol wine is likely cardioprotective in some ways that other types of alcoholic beverages are not.

Is It Safe To Drink Alcohol While Taking Blood Pressure Medications
With blood pressure medications, there are certain classes like beta blockers that are riskier to mix with alcohol than others, as well discuss below.
Its important to be honest with your provider about how much you drink regularly, as this might make a difference in which medication they prescribe for you. Its also possible that they may ask you to hold off starting a blood pressure medication until you cut down the amount you are drinking per day to prevent more serious complications.
