What Causes Low Blood Pressure?

What Causes Low Blood Pressure?

So, what causes your blood pressure to fall so low? Is it really that dangerous? Similar to high blood pressure, which is also known as hypertension, low blood pressure may have several causes. Let’s start with the first cause.

Heart Problems

What Causes Low Blood Pressure

Sometimes heart-related issues may lower your blood pressure. This can affect your blood circulation and may lower your blood pressure. Similarly, other heart conditions such as heart failure, heart attacks or issues in the heart valves might lower your blood pressure.

This is why it is important to have a healthy heart, which will pump blood at a proper rate, thus regulating the blood pressure and keeping your body functional. Please keep in mind one thing though, your heart also lowers your blood pressure when you are taking a rest after an exhausting activity.

So, if you are heading straight to the doctor’s clinic after a tiring day at the office then your blood pressure will read lower. This is temporary and doesn’t mean that you have low blood pressure. So, why would your heart be so “heartless”? Simple, to maintain proper body temperature.

Dehydration

What Causes Low Blood Pressure

Can we imagine life without water? Probably not, and this is exactly why you should consume an average of 3 liters of water every day.

Failing to do so may cause dehydration, a condition that lowers your blood pressure and forces the heart to pump blood at a faster rate than it is used to. Unfortunately, though, this is not where things stop. In fact, here they get worse.

The longer you stay without water, the effects of dehydration increases. This can lead to fatigue, nausea, fever and more. Dehydration may even cause a person to faint or feel very weak. So, the next time your doctor asks you to drink 3 liters of water every day, follow that advice without a second thought.

Loss of Blood

Admit it, you saw this one coming. Whether it is through internal bleeding or a severe injury, losing a lot of blood can lower your blood pressure. Imagine you are riding a bike on a freeway. It is a cloudy day and there is a little bit of a drizzle but nothing major.

All of a sudden it starts raining heavily, your tires start skidding and before you know it, you’ve just had an accident. Your injuries may be both external and internal. In both cases, there will be blood loss. As we mentioned earlier, a lower heart rate may lead to low blood pressure. In this case, if the loss of blood is less than 15% then there will be a small change in your heart rate.

On the other hand, if the blood loss is more than 15%, your heart rate will increase. This will happen in response to the fall in arterial and pulse pressure. Now, the heart needs to pump blood, but there is not enough blood to pump. So, what does the heart do?

It lowers your blood pressure and continues to do it a job. Now you might be thinking, “Does this mean both lower and higher heart rate may lead to low blood pressure?” not really.

A low heart rate means that the blood is being circulated slowly. Yes, it may lead to low blood pressure, but it’s not for sure. Whereas, if the heart rate has increased in response to blood loss then it is more likely that your blood pressure will lower.

Pregnancy

What Causes Low Blood Pressure

This is more of a temporary thing than a long term one. During pregnancy, a woman’s body is trying to make room for another individual or in some cases more than one.

This causes the tissues and muscles to expand so that the body can adapt. The circulatory system also expands rapidly during this time and lowers the blood pressure. Thankfully though, it usually shifts back to normal once a woman has given birth. In case it doesn’t, we suggest that you go to a doctor who can help you with this.

Septicemia

You may be aware of several bacterial infections that can harm your body. These infections usually affect your lungs, skin or other vital body organs, but sometimes they can enter your bloodstream. This type of infection is known as Septicemia.

How dangerous is this?

Imagine a bacterial infection that has access to your bloodstream, the bacteria, and its toxins will start spreading. If left untreated it may lead to sepsis, a complication that can cause inflammation throughout your body.

It doesn’t stop there though, it may cause blood clots and stop the blood supply to many of your vital organs, resulting in organ failure. Septicemia also lowers a person’s blood pressure drastically. If someone already has low blood pressure then this infection may cause septic shock, which can lead to respiratory failure, heart attacks, and even strokes. So yes, it is pretty dangerous.

Vitamin B12 Deficiency

What Causes Low Blood Pressure

Vitamin B12 is a water-soluble nutrient and this means that the body can’t store it in large amounts. As a result, it is important that you keep getting this nutrient through regular dosages, either through supplements or through your diet. Deficiency of this nutrient can lead to,

  • loss of memory
  • vision problems
  • weakness in muscles
  • fatigue
  • irrational mood swings
  • Low Blood Pressure.

This is one of those issues that can be controlled though. Just try to maintain a diet with a moderate amount of red meat, clams, fish, milk, cheese, and eggs.

This should help you keep your Vitamin B12 levels from dropping too low. Try to avoid overeating as it might have harmful effects on your body. Always have a variety of things in your diet but in moderation. Now that we know the causes and effects, there is just one question that is left to be answered.

Is it really that dangerous?

It depends, as we have already discussed in this article low blood pressure can be temporary like when women have it during pregnancy. Sometimes the blood pressure may fall because of loss of blood or heart problems. These scenarios can be dangerous depending on the severity of the case.

Even lack of nutrients may cause this problem, but it truly becomes life-threatening when it is accompanied by an infection like Septicemia. Low blood pressure can be kept in check with proper meals, proper sleep, and consumption of sufficient fluids in a day.

In case things get too intense, we would suggest going to your nearest doctor. So, we leave it to you. Do you think it is dangerous?
