5 Warning Signs You Don’t Have Enough Oxygen In Your Blood

“Oxygen is one of the most abundant elements in the universe. It’s a bit ironic, then, that people with breathing problems can’t seem to get enough of it.” – Deborah Leader RN, BSN, PHN

Breathing is an involuntary action that our bodies do whether or not we’re conscious of doing it. That means that we have to actively force ourselves not to breathe, rather than the other way around. Our bodies need oxygen to survive, not only to keep us breathing, but to circulate oxygen through our blood, which then circulates oxygen to all of our vital organs, our cells, and the tissue in our bodies.

When our blood doesn’t have enough oxygen, it’s called hypoxemia.

“Hypoxemia can be acute, occurring suddenly because of an emergency situation, or chronic, taking place over time because of a long-term health condition like COPD,” adds Deborah Leader RN, BSN, PHN.

Whether or not a low level of oxygen in the blood is causing extreme problems, there are still ways to tell when your blood isn’t getting the level of oxygen that it needs.

HERE ARE FIVE SIGNS YOUR BLOOD DOES NOT HAVE ENOUGH OXYGEN

1. WEAKNESS OR DIZZINESS

A common sign of having low oxygen levels in your blood is getting weak or dizzy more quickly than normal. Most people have experienced standing up too quickly and getting dizzy or their vision blacking for a short moment. However, people who don’t have enough oxygen in their blood often find that this happens on a daily basis, during any level of light or strenuous activity.

Family physician Dr. D. Love states, “The muscle can burn fuel without oxygen for a limited period of time, but it cannot be maintained indefinitely. Therefore, chronically low oxygen levels will cause muscle weakness. It would be unusual that a low oxygen level will cause muscle weakness as a sole symptom; it would be expected that there would also be shortness of breath.”

Since your blood carries oxygen all throughout your body, getting weak or dizzy quickly is a sign that your blood isn’t carrying enough oxygen to all the places that it needs to go.

2. FATIGUE

Chronic fatigue is a major sign that your body isn’t getting the oxygen that it needs in its blood. There are different types of feeling tired, but fatigue that is associated with hypoxemia is chronic and never-ending.

According to an article on Healthline, medically reviewed by Dr. Graham Rogers, “Without the proper exchange of gases, your body can’t get the oxygen it needs. Over time, you will develop low blood oxygen levels, a condition called hypoxemia. When your body is low on oxygen, you feel tired. Fatigue comes more quickly when your lungs can’t properly inhale and exhale air.”

People often report feeling exhausted halfway through the day, and no amount of sleep seems to be helping. Getting tired more quickly than others, or more quickly than you used to, is also a sign that your blood isn’t getting enough oxygen.

3. POUNDING OR RACING HEART

Feelings of anxiety are often categorized by a racing or fast-beating heart. This is a sign that your heart is working hard to get oxygen to all the places that it needs to go inside of your body because there isn’t enough of it. If you’ve never experienced anxiety symptoms before and your body has started to exhibit a racing heart without other anxiety symptoms, it might be due to a low level of oxygen in the blood.

4. SHORTNESS OF BREATH

Of course, lack of oxygen means that you’re going to have trouble breathing. When you have trouble breathing and pulling in oxygen, you’re going to have trouble getting enough oxygen into your blood as a result. People who have a lack of oxygen in their blood also report being short of breath whether or not they’re performing a strenuous activity.

5. HEADACHE AND CONFUSION

Ever get a pounding head after holding your breath? Many people experience headaches, and they can vary in severity. By themselves, headaches aren’t a worrying sign of lack of oxygen in the blood. But paired with confusion, dizziness and lack of coordination, headaches can be a sign that your body isn’t circulating the amount of oxygen that it needs.

“Your brain needs a certain amount of blood flow and oxygen to run efficiently and for us to feel healthy, and if that mechanism is damaged, your brain knows other ways to generate the pressure that it needs,” says Dr. Dr. Patrick M. Nemechek

When your blood lacks oxygen, it can be difficult to concentrate and coordinate your body, leading to headaches and confusion.

“Without enough oxygen in the lungs, the organs cannot function properly. As a result, toxins accumulate in the bloodstream and vascular headaches ensue. This happens because low oxygen levels initiate the widening of blood vessels and bring on migraines,” says Dr. Mark Wiley.

A lack of oxygen in the blood can be cause of concern, because it’s often the cause, or caused by, other diseases or illnesses. Fortunately, going to the doctor will help figure out how best to treat the issue.
