Can you reduce your risk of high blood pressure by avoiding or limiting alcohol? The answer is yes. If you have high blood pressure, reducing alcohol may be an important part of your treatment.

Drinking alcohol raises your blood pressure, even if you are not a heavy drinker. [1,2] Having an occasional three drinks during a meal or at a party could cause a temporary increase in blood pressure. [3] However, if you are a regular drinker – you drink two drinks or more every day – you could increase your risk for long-term hypertension. [1]

Hypertension is something you definitely want to avoid. It has been called the silent killer. Even when it is not causing any symptoms, it is increasing your risk for a deadly heart attack or stroke. It can also cause loss of vision, and heart or kidney failure. Avoiding alcohol can reduce your risk of hypertension. Reducing alcohol can help you treat hypertension. [3]

What Does the Research Say?

A 2019 study in the Journal of the American College of Cardiology, JACC, reviewed alcohol drinking and high blood pressure in over 17,000 Americans. They found that people who drank just 7 to 13 drinks per week significantly increased their risk of hypertension compared to people who did not drink alcohol. In fact, there was up to double the risk for these drinkers. [1]

In 2017, the medical journal Lancet Public Health reviewed 36 trials on lowering blood pressure by reducing alcohol. The review found that people who drank more than two drinks per day could reduce their systolic blood pressure (the upper number) by about five points if they reduced alcohol down to two or fewer drinks per day. They concluded that avoiding alcohol  could be as effective for treating high blood pressure as exercise and weight loss. [2]

Limit Alcohol to Prevent Hypertension

According to the American Heart Association (AHA), you can reduce your risk of hypertension by limiting the amount of alcohol you drink. This is called only drinking alcohol in moderation. That means no more than one drink per day for a woman, and no more than two drinks for a man. [5] If you are a man age 65 or older, you should drop down to just one drink per day. [4] This is the definition of one drink:

  • 12 ounces of beer
  • 4 to 5 ounces of wine
  • 5 ounces of 80-proof hard alcohol like whisky or rum [4,5]

AHA adds that red wine is not a heart-healthy miracle. The belief that red wine is good for your heart is mostly myth, so don’t use that as an excuse to drink more than the limit. [5] Alcohol also has empty calories that can contribute to weight gain, which is another risk factor for hypertension. [4]

The Centers for Disease Control and Prevention (CDC) includes drinking alcohol only in moderation as one of six healthy lifestyle choices that reduce your risk for hypertension. The others are:

  • A diet high in fruits and vegetables and low in salt and saturated fats
  • Losing weight or maintaining a healthy weight
  • Being physically active
  • Not smoking
  • Getting enough sleep [6]

Limit Alcohol to Treat Hypertension

If you have already been diagnosed with hypertension, you should talk to your doctor about how much alcohol you can drink. Your doctor may advise avoiding alcohol or drinking only in moderation. Another danger for people with hypertension is that alcohol can interfere with blood pressure medications and increase side effects of medications. [4]

Studies show that heavy drinkers benefit the most from reducing alcohol or abstaining from alcohol. For many heavy drinkers, quitting or cutting back can be difficult. If you are struggling with your alcohol use talk to your doctor. If you drink three or more drinks every day, it is a good idea to reduce alcohol gradually over one to two weeks. Stopping suddenly can cause a severe rise in blood pressure that could be dangerous. [4]

  • This was very informative, and it’s great to know the effects are reversible. Only one thing bothered me at the end of it… the statement “try cutting back or abstaining altogether”… I did read elsewhere that suddenly abstaining can cause a spike in blood pressure for days, so for heavy drinkers it is best to wean off of the alcohol. Just wanted to point that out.

  • I NOTICED THIS! We had a blood pressure machine in our lunchroom at work. I picked up the nasty habit of binge drinking in college and every weekend for nearly 20 years would down a good ten drinks. Had two bottles of red wine on a Saturday and was still feeling nasty on Monday. Decided to try out the BP thing that day and was shocked to see 158/105 as I obstainded from Alcohol during the week I kept checking. Teus was 140s/90s then 130s/lower 90s and returned to 120/80 on Friday. Drank less the next weekend but noticed it was still elevated again on Monday but not as bad and returned to normal quicker this time. My Dads side has a history of Hypertension, also most are heavy drinkers on his side as well. As much as I love my red wine I decided to quit four months ago and feel much healthier.

  • Why I have no explanation for it, I recently began drinking vodka and fruit juice in the evening and my blood pressure has come down so much that I have been able to eliminate one of the 2 BP drugs that I was on. Beer on the other hand will cause a temporary drop in me, but my BP always spikes the next day.

  • Wonderful goods from you, man. I’ve remember your stuff previous to and you are
    just extremely fantastic. I really like what you’ve acquired right here, really
    like what you are saying and the way by which you say it.
    You’re making it entertaining and you continue to care for to stay it
    smart. I can not wait to learn much more from you. That is really a wonderful website.

  • Thank you very much. I just checked my BP. It is 160/105. I got scared. I am on medication and my BP has been Normal. I have been drinking in the last month one liter of whisky every five days. So I am not going to drink any more. And today I doubled my medication (diovan) from 80mg to 160.
    Thank you again

  • I’ve been reading and reading and reading! And I think we all know that unless you drink less than 2 drinks a day you are gona always be at some risk! Checking myself into rehab. I wana live. If not for myself… then my kids who need me the most! ❤️

  • I have to say Im very skeptical of this side of the study. I suffer from hypertension and I used to drink 8 beers every Friday and Saturday night. I gave up because of this information and although my blood pressure came down about a week or 2 after I gave up drinking altogether, it then began to rise again a couple of weeks later until it was actually worse than before I gave up drinking. And it is still worse than before I gave up drinking, so there you go. From personal experience, I’m not sold on alcohol in moderation being bad for blood pressure.

  • My bp rises 150/100 when I drink but comes back to normal
    120/80 whenn I dont. I am not under medication. Why is this or is it normal?
