Can Low Blood Pressure Cause Erectile Dysfunction

Can Low Blood Pressure Cause Erectile Dysfunction?

Erectile dysfunction is a problem that is very common in men. It can strike any man no matter what age, with the frequency increasing as they get older. This becomes a problem in sexual intercourse leading to dissatisfaction for men and their partners.

It is becoming so frequent and commonplace that this dysfunction may affect over 300 million men by 2025, with additional risk factors linked with it. 

Apart from age, there are many other factors that contribute to this dysfunction. In this article, we’ll examine whether or not low blood pressure or hypotension is among the factors that can cause it. 

How do Erections work?

Before we dive in, it is important to understand the underlying mechanism of the erection. How do erections work? What goes on in men’s bodies to make it happen? 

The Primary Players

Well, the erection of a penis all starts in the shaft. Within this shaft are side-by-side chambers identified as corpora cavernosa, translated into “cave-like body”. This cave is made up of spongy tissue and is the primary driver of erection. 

Within the cavernosa are arteries, veins, and muscle fibres that are smooth. 

The stage has been set. The players have been identified. Let’s see what happens in men’s bodies to make erections happen.

How does It happen?

When an erection is taking place, signals from the brain travel south to the nerve endings found in the penis. Once the message is received, the smooth muscles in the cave-like chamber begin to relax. 

This relaxation allows for the arteries in the area to dilate and widen. With all that extra space in the arteries, more blood begins to flow in, filling the new space created. 

Due to the pressure of the blood flow, the tissue within the chamber starts to constrict around the veins. This allows for blood to be trapped within the penis. The more blood that comes in, the more the penis enlarges and becomes stiff. 

Thus, an erection takes place and is maintained. 

Can Low Blood Pressure Result in Erectile Dysfunction? 

Now that we understand how erections take place, we can better surmise the potential effects that blood pressure, specifically low hypotension, has on it. 

On Low Pressure As a Cause

The simple answer to the question is a resounding no. Hypotension does not cause any dysfunction for the erections. In fact, it isn’t hypotension that is the potential culprit, but hypertension. 

The True Culprit: Hypertension

It may seem counterintuitive for hypertension to be a cause. As stated previously, more blood flow to the penis makes it larger and stiffer. 

The problem with having high blood pressure though is that the increased pressure damages blood vessels within the body. This includes the crucial vessels within the penis. If damaged enough, they become too narrow to let any blood in. 

Additionally, this pressure also makes it so that the muscles in the penis cannot relax. This means that less space is made for the blood to come rushing in. 

Further Complications

Hypertension also brings with it several other factors that serve to complicate the erection. Apart from the flow of blood, hypertensive males tend to have low testosterone. This hormone plays a big factor in arousal and subsequently an erection.

Ironically, certain medicines that help treat hypertension also contribute to the dysfunction of erections.

For instance, diuretics decrease the flow of blood to the penis. At the same time, taking this pill decreases the amount of zinc in the body, a vitamin that is needed to create testosterone. 

Another one is beta-blockers. They weaken how bodies respond to impulses from the nerves. 

How to Treat Erection Problems?

Discuss Your Medications

The first thing you should do if you think your hypertension is causing ED is to talk to your doctor. Many times, they can change the dosage or type of medicine you’re taking. There are also other medications available that don’t have sexual side effects.

The important thing here is that you become honest with your physician. Be open about your concerns regarding this dysfunction and see what possible solutions you can come up with.

Meet Your Doctor

Even if you’re not currently experiencing problems with erections, it’s important to monitor your blood pressure. This is because hypertension often has no symptoms until serious damage has been done. Meeting with a doctor regularly will help make sure that your blood pressure stays at a healthy level.

Check for Other Causes

Erection problems can also be caused by other health conditions.


Diabetes can damage blood vessels and nerves similar to hypertension. This makes it difficult for signals to be sent from the brain to the penis. As a result, blood flow is reduced and an erection cannot be achieved.

Heart Disease

Heart disease can also restrict blood flow to the penis. This is because the heart is not able to pump as much blood when it is diseased. Atherosclerosis, or the hardening of arteries, is especially dangerous as it narrows the arteries and limits blood flow even further.

Thyroid Problems

Thyroid problems can also lead to sexual dysfunction as this gland regulates hormones in the body. When it isn’t functioning properly, testosterone levels can drop, leading to a loss of libido and erectile problems.

Improve Overall Health

Making lifestyle changes is essential to keeping hypertension and erection problems under control. This includes eating a healthy diet, exercising regularly, and activities like smoking..


According to a recent study, physical activity and exercise are important in battling dysfunction. The best types of exercise are aerobic in nature, with it being done at least four times every week. 

These sessions should last at least 40 minutes. This routine should be taken for at least half a year in order to see any relevant changes. 


There is a specific diet that can help address hypertension, and subsequently, erectile problems. This is called “DASH” or Dietary Approaches to Stop Hypertension. 

This type of diet puts things like vegetables, fruits, and whole grains into the spotlight. At the same time, it also aims to take away as much salt, sugar, and fat as possible.

In just two weeks, it can improve a person’s blood pressure levels. 


Additionally, quitting smoking is a very critical factor. Just like the other causes, smoking hampers the blood vessels in parts of the body, one of them being the penis.

Smoking’s effect on reproduction is so widespread that it can affect smokers who are as young as 20 years old.

Make a Change For the Better

Erectile dysfunction caused by low blood pressure is a myth that we have debunked. Now, we understand that the true culprit is high blood pressure, which is a serious condition in its own right.

Note though that both high and low levels of blood pressure are dangerous, but in terms of sexual performance, the former is more serious.

Thankfully, hypertension is easily spotted in people. In addition, there are many ways to treat it. These include discussing your medications with your doctor, making lifestyle changes, and checking for other causes. With the right treatment, you can enjoy healthy and active sex life. You can make a change for the better with the right decisions.

Apart from reproductive issues including erection problems, hypertension brings along a whole host of health problems that should also be worried about and treated.

If you or a loved one are living with hypertension, it may be in your best interest to learn about the right first aid practices. The various problems it brings are dangerous and can often result in fatal situations.

Understanding first aid practices can not only help you identify the signs of symptoms these problems bring, but also how to administer care.
