What Are The Symptoms Of High Blood Pressure
You can’t usually feel or notice high blood pressure. In fact, many people may not know they have it. This is because high blood pressure very rarely causes any obvious symptoms until a serious acute event such as a heart attack or stroke.
The best way of knowing if theres a problem is to have your blood pressure measured. You can have this done at your GP surgery, some local pharmacies, at your NHS Health Check or you can buy a reliable blood pressure monitor from the pharmacist.
Effects Of Alcohol On Blood Pressure
Alcohol-related hypertension, or high blood pressure, impacts about 16% of the population. About half of U.S. adults have some form of high blood pressure or take blood pressure medications, the CDC says.
A study in The Journal of Clinical Hypertension says that just one drink may raise blood pressure for at least 2 hours. If you regularly have more than two drinks, you could be at risk for long-term high blood pressure.
âRepeated alcohol consumption can lead to long-term blood pressure abnormalities, which can present health risks that need to be medically monitored managed,â Ashley McGee, RN, Vice President of Nursing at Mountainside Alcohol and Drug Treatment Center in Connecticut, tells WebMD Connect to Care.
Early hypertension usually doesnât bring on noticeable symptoms, but it can slowly damage your arteries, kidney, brain, and heart. Untreated hypertension can eventually lead to heart attack and stroke.
Men are more likely than women to have high blood pressure, the CDC says. In fact, even small amounts of alcohol can increase hypertension risk in men. As for binge drinking, younger men are more likely to experience high blood pressure from excess alcohol use than younger women.
But stroke risk can increase in men and women of all ages who binge drink regularly. The CDC defines binge drinking as four drinks in 2 hours for women and five drinks in 2 hours for men.

Symptoms And Complications Of Alcohol
All long-term heavy drinkers run the risk of developing a specific form of high BP called portal hypertension. This condition occurs when pressure levels increase in a vessel called the portal vein, which channels blood to the liver from the gastrointestinal tract and the gallbladder, pancreas, and spleen. Portal hypertension does not produce any direct symptoms.
However, Its Effects Can Lead to Complications that Include:
- A distended abdomen
- Varicose veins in the upper GI tract
- Potentially heavy bleeding from damaged varicose veins in the upper GI tract
The underlying cause of portal hypertension in most chronic heavy drinkers is an advanced form of liver disease called cirrhosis. This condition occurs when scar tissue begins to replace the livers healthy cells. It typically appears after a decade or more of severe ethanol abuse.
System-wide hypertension can also lead to various severe and long-term health problems in anyone affected by alcoholism. Many of these problems appear in the cardiovascular system. For example, people with chronic high BP have increased chances of experiencing a coronary artery blockage followed by a heart attack. They also have increased chances of experiencing heart failure, a condition that occurs when the heart can no longer pump with enough force to meet the bodys requirements for oxygen-bearing blood.
Other Cardiovascular Conditions Linked to Hypertension Include:
How Much Alcohol Is Safe For Hypertension Patients
Alcohol has been well studied in relation to high blood pressure, and while some clinical studies suggest that moderate consumption can be used to lower blood pressure, most experts recommend refraining from any alcohol use to maintain good overall health.
In addition to an increased risk for cardiovascular issues, consuming more than three alcoholic drinks daily can increase the risk for high blood pressure by 70%.
Cutting down on alcohol can be challenging for heavy drinkers, whereas those who drink socially may be able to avoid alcohol more easily.
Hypertension patients who need to limit their alcohol should do so at a slow and steady pace. Reduce drinks over several weeks as blood pressure could rise significantly if heavy drinkers stop use abruptly.
High blood pressure patients who do consume alcohol are advised to limit drinks in accordance to age and existing health condition.
Moderation is key and can be defined as two alcoholic drinks daily for males under 65 years of age and one daily glass for older men. Women are advised to limit alcohol beverages to one per day at any age.
One drink may be a 12-oz. glass of beer, a 5-oz. glass of wine, or a 1.5-oz. glass of spirits.

Are There Any Blood Pressure Medications That Are Not Affected By Alcohol
Its important to remember alcohol has both direct and indirect effects on medications. Most blood pressure medications are not directly affected by alcohol. This means the alcohol does not change the physical properties of the medication. Alpha blockers, nondihydropyridine CCBs, and beta blockers are three classes of antihypertensives that can be directly affected by alcohol, which is why its dangerous to drink while taking them.
The bigger concern is alcohols indirect effects when it comes to hypertension and medications that treat it. Alcohol is known to raise blood pressure when consumed regularly and will make it harder for your medication to treat your condition. Over time, this puts you at a higher risk for heart attacks and strokes.
Because of alcohols indirect effects, there are no blood pressure medications that are risk-free when mixed with alcohol. Its important to discuss with your provider if theres a safe amount you can drink while taking your medications.
With Blood Pressure In Mind Is There A Safe Amount Of Alcohol To Drink
According to the American Heart Association , women should stick to no more than 1 drink per day and men should stick to no more than 2 drinks per day. If youre wondering whats considered 1 drink, here are the guidelines:
12 oz beer
1.5 oz of 80-proof alcohol
1 oz of 100-proof alcohol
If you struggle with alcohol abuse or addiction, you can find helpful resources through the American Addiction Centers.

Stretching And Drooping Of The Heart Muscle
Long-term heavy drinking can cause the heart muscles to weaken. This is called alcoholic cardiomyopathy.
If your heart muscle is droopy and stretched it cant pump blood around your body very well. If the blood flow to other parts of your body is not enough, it can damage organs and tissues.
It can also cause symptoms like:
- breathing difficulties
Alcohol And Blood Pressure: What Are The Effects
Disclaimer: Results are not guaranteed*** and may vary from person to person***.
The relationship between the long-term use of alcohol and blood pressure levels is a major medical concern as alcoholic drinks are commonly consumed by most cultures in the world, and one in eight American adults suffer from alcohol abuse.
Chronic alcohol consumption can have damaging effects on the liver, digestive tract, and vascular system, which leads to elevated blood pressure levels. This increases the risk for serious cardiovascular issues, like heart attack and stroke.
The link between alcohol and blood pressure levels was first documented in the early 1900s. Dozens of studies since then have worked to establish the physiological mechanism behind the relationship, and research is still ongoing.

Why Does Alcohol Cause Hypertension
Alcoholic beverages are regular drinks in most parts of the world. If consumed in little to moderate amounts, alcohol can be healthy for most individuals. However, drinking too much alcohol can create many problems including an increase in blood pressure. Having more than three drinks back-to-back can increase your blood pressure temporarily, but if you keep doing it frequently, you may develop a long-term condition called hypertension .
- Damage to the endothelium
- Effect on the nervous system
- Changes in sensations of blood pressure receptors in the body
- Increase in cortisol
- Increased calcium levels in the walls of the arteries
- Effect on hormones that constrict and relax the arteries
Heavy alcohol drinking increases blood pressure by about 5 to 10 mmHg and the increase in systolic pressure is more than that in diastolic blood pressure.
How Does Alcohol Affect High Blood Pressure
Although anyone can develop high blood pressure, there are certain factors known to increase a persons risk, such as consuming alcohol.3
When an individual has a single alcoholic drink, it leads to an acute rise in blood pressure however, this typically resolves within 2 hours.6
To better prevent high blood pressure, the American Heart Association suggests limiting alcohol intake to no more than 2 drinks per day for men and no more than 1 drink per day for women.7

Criteria For Considering Studies For This Review
Types of studies
All randomised controlled trials that compared alcohol to placebo or similar tasting nonalcoholic beverages were included in this systematic review.
Types of participants
We included adult participants of both sexes without any restriction on their health condition.
Types of interventions
Low dose .
Medium dose .
High dose .
Types of outcome measures
Change in resting seated systolic and diastolic blood pressures at three different time periods after alcohol intake: early intermediate and late
Change in resting heart rate at the same time periods as blood pressure outcomes above
Change in resting mean arterial pressure at the same time periods as blood pressure outcomes above
Why It Is Important To Do This Review
Several systematic reviews based on cohort studies have concluded that alcohol intake has a considerable effect on blood pressure and on risk of hypertension . It has also been shown that heavy alcohol consumption causes hypertension and leads to left ventricular dysfunction and dilated cardiomyopathy. On the other hand, abundant epidemiological and clinical evidence shows that light to moderate drinking is associated with reduced risk of coronary heart disease , incidence of stroke, and total mortality among middleaged and elderly men and women .
All these conclusions are based on findings of observational studies. Several RCTs have reported the magnitude of effect of alcohol on blood pressure, but because those trials are small, their findings are not sufficient to justify a strong conclusion. In 2005, McFadden and colleagues conducted a systematic review of RCTs, which investigated the haemodynamic effects of daily consumption of alcohol . Based on nine RCTs in which participants consumed alcohol repeatedly over days, these review authors reported that alcohol increases SBP by 2.7 mmHg and DBP by 1.4 mmHg. However, they excluded studies for which the duration of BP observation was less than 24 hours and articles published in nonEnglish languages. We believe that inclusion of those studies will provide useful information about the doserelated magnitude and timecourse effect of alcohol on blood pressure in people with both normal and elevated blood pressure.

Too Much Of A Good Thing
Your age and other risk factors linked to heart and blood pressure health will ultimately aid your decision with your doctor about drinking. But don’t expect any âall clearsâ for anything beyond light-moderate drinking.
Having more than two drinks in a day may raise your blood pressure. Drinking more than one or two drinks in a sitting has been directly linked to a rapid rise in blood pressure, which in someone with very high levels of hypertension can lead to stroke.
âIt doesnât matter what beverage if you have a high risk, itâs all about the amount,â Klatsky says. âThereâs plenty of research that shows heavy beer drinkers, heavy wine drinkers, it doesnât matter, they are all at risk of increasing high blood pressure when drinking in excess.â
Klatsky says his biggest concern is that patients keep an open dialogue with their doctors about their lifestyle to achieve an authentic diagnosis.
âOne rule doesnât fit everyone,â he says, âso talk to your doctor about how your high blood pressure — and the rest of you — can determine your consumption choices.â
Differences Between Protocol And Review
According to the published protocol, we intended to include only doubleblind RCTs in this review. Because higher doses of alcohol exert specific pharmacological effects on drinkers, we had a few doubleblind RCTs after the first screening. Considering the difficulty of masking in these types of studies, we decided to also include singleblind and openlabel studies in the review.

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.
How Does Alcohol Affect People With Hypertension
You may have heard that 1 or 2 drinks per day particularly red wine is good for your heart. Unfortunately, this isnt necessarily true. While there have been studies that showed people who drank a moderate amount of red wine every day had better heart health, these people also did other things that are known to lower your risk for heart disease, like eating a healthy diet.
When youre drinking, alcohol temporarily raises your blood pressure if you have 3 or more drinks at a time. But those temporary rises in blood pressure may turn into chronic hypertension if you regularly engage in binge drinking long-term .
Drinking alcohol also can indirectly lead to chronic high blood pressure. Alcoholic beverages can have a lot of calories and sugars, which can cause weight gain over time. People with overweight or obesity have a higher risk for developing hypertension.
Drinking alcohol in moderation regardless of what you are drinking continues to be the best advice.

Can You Drink Alcohol With Blood Pressure Medicine
Most prescription and over-the-counter medications come with a label warning against alcohol use. But how does alcohol affect blood pressure medication in particular?
First, it is important to know that each hypertension drug works to lower levels in a unique way.
- Angiotensin-converting enzyme inhibitors regulate blood pressure hormones.
- Angiotensin II receptor blockers, or ARBs, control blood pressure-related hormones, similarly to ACE inhibitors.
- Calcium channel blockers help the lining of the blood vessel walls expand, which sees a drop in blood pressure levels.
- Thiazide diuretics remove excess fluid to regulate the flow of blood.
Certain high blood pressure cases may require a regimen of more than one of these medications. The use of alcohol may hinder the effectiveness of the drugs.
Alcohol combined with the chemical properties of blood pressure medication may cause severe drowsiness, dizziness, headaches, and muscle weakness.
The Connection Between Hypertension And Alcohol
Hypertension, also known as high blood pressure, affects nearly half of the U.S. adult population and can be a result of many factorsone of them being alcohol consumption.
Many Americans drink alcohol at least occasionally and for most, moderate drinking is relatively safe, but when drinking heavily over time becomes part of a persons lifestyle, they can greatly increase their risk for hypertension and other harmful conditions.

Will Quitting Alcohol Lower Blood Pressure
A study has reported that heavy drinkers who completely stopped drinking for a month managed to lower their systolic pressure by about 7.2 mm Hg and their diastolic pressure by 6.6mm Hg.
Almost 72% of these participants, who were initially categorized as hypertensive, were no longer considered so after giving up alcohol for a month.
The results showed that excessive consumption of alcohol played a critical role in increasing blood pressure. So, drinking in moderation or quitting altogether is recommended as part of the treatment for high blood pressure in people who regularly consume high amounts of alcohol.
Moderate consumption or abstinence
Moderating or abstaining from alcohol consumption is the best non-medical option available for lowering alcohol-induced high blood pressure. These behaviors can also help prevent the development of high blood pressure among healthy adults.
Try to gradually reduce consumption to one or two drinks per day then, try to stop drinking altogether. If you have problems moderating or limiting alcohol consumption, there are many options available for support, such as rehab and counseling.
Lack of exercise and an inactive lifestyle can contribute to the development of high blood pressure, and studies have shown that physical activity helps control blood pressure.
There are some pharmacological medications available to help lower alcohol-related hypertension.
