signs of hyperventilation

What is Hyperventilation? 

The signs of hyperventilation occur when someone breathes too quickly and deeply, exhaling far too much carbon dioxide for the body to replenish. When this happens, it leads to lower than normal carbon dioxide levels in the body, and more specifically the blood. The proper name for this is hypocapnia if you want to sound smart.   

Carbon dioxide is vital for regulating our respiration and blood pH levels, so when the amount of carbon dioxide in the body gets too low from overbreathing, the blood begins too alkaline.   

Highly alkaline blood can cause the blood vessels to tighten, restricting blood flow to the organs in the body, including to the brain, this is what causes the signs of hyperventilation to start to show.   


What Causes Hyperventilation? 

Some people may go their whole lives without experiencing signs of hyperventilation, whereas others will be more prone to having them due to a wide range of physical and mental health conditions, which we’ll get into.  

People who suffer from the signs of hyperventilation on a frequent basis might have a condition known as hyperventilation syndrome, which is usually diagnosed by their GP.  

Most of the time, hyperventilation is brought on by intense emotional states, this can be through mental health conditions like anxiety or depression, as well as extreme stress from work or in their private lives. The condition can be brought on by experiencing phobias, fears or from experiencing frightening events.   

Signs of hyperventilation can happen due to other lesser-known reasons. Some of the causes include: 

  • Being pregnant  
  • An overdose of legal or illegal drugs  
  • Diabetes  
  • Heart attack  
  • Asthma  
  • Too many stimulants  

The list goes on, and sometimes you might experience hyperventilation but have no idea what the root cause of it might be. You should consult a medical professional if you experience the condition, so they can help understand what might have caused it.

Is a Panic Attack the Same as Hyperventilation? 

Often misconstrued for one another, the signs of hyperventilation are often mistaken for a panic attack, though many of their symptoms overlap.  

Hyperventilation is the medical term given for the loss of carbon dioxide in the blood, whereas a panic attack is the process of experiencing intense fright, this can be from being jump scared in a movie, woken up in the night by a loud bang, or recalling a traumatic event from childhood.  

Panic attacks can cause you to hyperventilate, and vice versa, but they are not the exact same condition.  


The Signs of Hyperventilation 

So, let’s start getting into the signs of hyperventilation, which is probably the reason you clicked on this article in the first place. The signs can vary from person to person, but generally, they tend to be the same, or at least very similar for everyone who hyperventilates.   

Spotting the signs of hyperventilation early gives you the chance to get into a safe space and get the help you may need while you are experiencing the condition.   


1.Increased Heartrate  

During hyperventilation, the reduced carbon dioxide in the blood causes the blood vessels to constrict, which puts greater strain on the blood flow to the heart. This forces the heart to pump harder and faster to try to force the blood through the narrow blood vessels.   

Your heart rate starts to increase to try to compensate for the decreased blood flow to the brain and other organs. The side effects of a high or increased heart rate are dizziness, light headiness or shortness of breath. 



2. Dizziness, Light-headedness or Headaches 

Possibly one of the more common signs of hyperventilation is dizziness, light-headedness or acute headache. It will usually be the first thing that people notice, as their sense of perception will slightly shift, this is usually when they become overwhelmed through anxiety or stress. The lack of circulation in the body will often cause headaches, so it’s not surprising that hyperventilation can cause your head to be one of the first places you notice changes or pain.

3. Breathlessness

Shortness of breath or being unable to get a full deep breath can indicate someone may be experiencing hyperventilation. Rapid, deep breathing during hyperventilation actually expels too much carbon dioxide from the body.  

This leads to constricted airways and oxygen deprivation that creates a sensation of breathlessness, which for many can be frightening.  

The frequent and ineffective breaths that follow as a result often make the situation much worse.

4. Muscle Spasms  

Overbreathing during hyperventilation can cause calcium levels in your blood to drop drastically, resulting in muscle spasms throughout your body, but most commonly in the hands or feet. This is one of the signs of hyperventilation that can be the scariest, but it is quite normal to experience, so try not to get too overwhelmed as it should pass, and being afraid will only make the symptoms worse.  


5. Chest Pain 

During hyperventilation, chest pain can occur due to the stress that overbreathing causing your chest muscles and the rib cage to become tired. Chest pain will usually occur after the intense breathing that come during hyperventilation, so you might not notice it straight away.  

There are other factors that could play a part in you experiencing chest pain, this could be related to the heart and the stress its under when there is a lack of carbon dioxide in the blood.

6. Numbness or Tingling Sensation Around the Mouth  

Not many people know this, but people who hyperventilate can experience a tingling sensation around the mouth, lips, tongue or even feet, as well as the feeling of numbness. It’s believed that these areas of the body are responding to the lack of blood flow to them because of the lack of carbon dioxide in the blood, preventing it from reaching these areas.  

If you experience these signs of hyperventilation, it’s important you stay vigilant and inform someone close by that you might be having an attack.
