Binge Drinking and Blood Pressure

Binge Drinking and Blood Pressure

If you’re under the age of 65, high blood pressure probably isn’t the biggest of your concerns. But… should it be?Turns out, that depends. A whole variety of factors can play into it, but a massive one is increasingly prevalent for Millenials and Gen-Z. It’s alcohol consumption. If you’re drinking more than a little bit (and doing that regularly), there’s a good chance your blood pressure is elevated beyond what’s considered healthy.

Here’s the thing: alcohol consumption is a widespread practice among humans worldwide. From celebrating special occasions to unwinding after a long day, most people enjoy indulging in an alcoholic beverage. However, it’s important to recognize the potential health risks associated with regular alcohol use and most especially binge drinking, particularly its impact on blood pressure. High blood pressure, (or hypertension), is a prevalent condition that can lead to serious cardiovascular issues. In this article, we’ll explore the relationship between alcohol and blood pressure, the short-term and long-term effects of alcohol consumption, the mechanisms behind alcohol-induced hypertension, and the potential benefits of reducing or quitting alcohol consumption.

Binge Drinking and High Blood Pressure: An Overview

Blood pressure is a measurement of the force exerted by circulating blood against the walls of blood vessels. High blood pressure can strain the blood vessels and organs, increasing the risk of kidney disease, heart attack, and stroke. Studies have shown that binge drinking can lead to chronically high blood pressure, a condition known as hypertension. While moderate alcohol consumption has been linked to potential cardiovascular *benefits (*don’t get too excited), the long-term effects of binge drinking significantly outweigh any potential advantages.

Short-Term Effects of Binge-Drinking on Blood Pressure

The immediate impact of alcohol on blood pressure varies depending on the amount and frequency of alcohol consumption. Low doses of alcohol typically do not affect blood pressure in the short term. However, binge drinking, defined as consuming five or more drinks for men and four or more drinks for women within a two-hour period, can cause a temporary spike in blood pressure. It is essential to note that these blood pressure changes are transient and normalize within a few hours after alcohol consumption

Long-Term Effects of Binge Drinking on Blood Pressure

While low to moderate alcohol consumption may not have a significant impact on blood pressure in the long term, binge drinking can lead to the development of chronic hypertension. Individuals who consume more than 30 grams of alcohol per day are at a higher risk of developing high blood pressure. Chronic blood pressure elevation can persist even when an individual is not actively drinking, making it crucial to address alcohol consumption as a contributing factor to hypertension. Basically, even when you’ve long left your college campus, this issue’s going to follow you around.

Mechanisms Behind Alcohol-Induced Hypertension

Ok, a lot of medical terminology incoming. Alcohol affects blood pressure through various mechanisms within the body. These include increased renin levels, which promote fluid retention and constrict blood vessels, changes in baroreceptor sensitivity, elevated cortisol levels, alterations in the sympathetic nervous system, and increased calcium levels that promote arterial constriction. These physiological changes contribute to the elevation of blood pressure and the development of hypertension in those who tend to binge drink.

Alcohol and Medication Interactions

I can already see your thinking. You’ll just run out, see a doctor, grab some blood pressure meds, and carry on your merry way. It’s like a get out of hypertension free card, right? Wrong. Super wrong. Alcohol can interact with blood pressure medications, potentially amplifying their effects and leading to adverse reactions. The liver metabolizes alcohol, diverting its resources from processing medications. This can result in slower medication clearance from the body, prolonging their effects and increasing the risk of side effects. Combining alcohol with blood pressure medications can also cause a sudden drop in blood pressure, leading to dizziness or fainting. You’re trying to quit passing out on friend’s sofas, and mixing alcohol with your meds certainly won’t be doing you any favors.


Health Risks of Binge-Induced Hypertension

So I drink a little bit (a lot) and now have high blood pressure. So what? I’ll be fine. Well, alcohol-induced hypertension poses more than a few significant health risks, including an increased likelihood of developing cardiovascular diseases. Excessive alcohol consumption can exacerbate the damage caused by hypertension to the heart and kidneys. Studies have shown a dose-dependent relationship between alcohol consumption and the risk of stroke, ischemic heart disease, hypertensive disease, heart failure, and aortic aneurysm. Binge drinking can also lead to left ventricular diastolic dysfunction and subclinical heart damage, particularly in individuals with pre-existing hypertension. If you aren’t a doctor and have no idea what I’m on about, just copy and paste these things into google. You’re about to gain a whole different appreciation for your aging parents.

Ok… What About Red Wine?

At this point, you’re probably getting ready to argue with me because you’ve seen like 8 TikToks today about how good for you red wine is. And to an extent, those videos are accurate. There is a common belief that red wine can have cardiovascular benefits due to its high polyphenol content. Polyphenols possess antioxidant and anti-inflammatory properties that may contribute to heart health. However, it is important to note that the potential benefits of red wine consumption are likely attributed to other factors, such as lifestyle choices or the Mediterranean diet, rather than the alcohol itself. So if you’re considering filling the shot glass with Cabernet, realize that that alone is not going to help you quite as much as you’d like.

The Benefits of Reducing Alcohol Consumption

Reducing or quitting alcohol consumption can have significant positive effects on blood pressure and overall health. Studies have shown that decreasing alcohol intake can lead to a decrease in blood pressure readings, particularly among individuals who tend to binge drink. Limiting alcohol consumption to moderate levels, as recommended by healthcare guidelines, can help individuals achieve better blood pressure control. Additionally, quitting alcohol can lead to improvements in endothelial function and a reduction in the risk of cardiovascular diseases associated with high blood pressure.

Lifestyle Factors and Hypertension

In addition to alcohol consumption, several lifestyle factors contribute to the development and management of hypertension. These include maintaining a healthy weight, engaging in regular physical activity, adopting a balanced diet low in sodium and high in potassium-rich foods, quitting smoking, and managing stress levels. Implementing these lifestyle modifications can complement the effects of reducing alcohol consumption and contribute to better blood pressure control.


Understanding the relationship between alcohol and blood pressure is crucial for maintaining cardiovascular health. While moderate alcohol consumption may have potential benefits, heavy and binge alcohol use can lead to chronic hypertension and increase the risk of cardiovascular diseases. Quitting or reducing alcohol consumption, in combination with adopting a healthy lifestyle, can help you achieve better blood pressure control and improve their overall well-being.
