Low Blood Oxygen and How it Affects the Body

One of the many challenges of living with a chronic lung disease is low blood-oxygen levels. When the organs, cells and tissues of the body do not receive enough oxygen, hypoxia can occur. Having a chronic lung disease can increase your risk of developing hypoxia. We’re here to help you better understand low blood oxygen and how it affects the body.

What is hypoxia and why is it dangerous?

Hypoxia, sometimes referred to as hypoxemia, is a below-normal level of oxygen in the blood, often experienced by people with breathing or circulation problems. To measure hypoxia, a blood sample measuring the arterial blood gas may be performed, or it can be estimated by measuring oxygen saturation in the blood using a pulse oximeter.

What are the signs and symptoms of hypoxia or low blood oxygen levels?

  • Wheezing
  • Frequent cough
  • Choking sensation
  • Waking up out of breath
  • Bluish discoloration of the skin
  • Shortness of breath while resting
  • Severe shortness of breath after physical activity

Low blood oxygen levels and lung disease

Low Blood Oxygen and How it Affects the BodyChronic lung diseases, such as COPD, emphysema and chronic bronchitis, cause breathing difficulty and are characterized by the restriction of airflow. Restricted airflow increases the risk of developing hypoxia.

What are the complications of hypoxia or low blood oxygen?

Although hypoxia induced by chronic lung disease hinders breathing, it affects more than the lungs. If you find it difficult to inhale, or to receive adequate amounts of oxygen, your blood becomes oxygen deprived—a serious situation. All organs, tissues and cells in the body need oxygen, so taking action to ensure adequate oxygen intake is important.

What is oxygen therapy?

Low Blood Oxygen and How it Affects the BodyMany doctors prescribe supplemental oxygen or oxygen therapy for people with lung diseases who aren’t getting enough oxygen. The goal of oxygen therapy is to help you receive enough oxygen.

What is a normal blood oxygen level, and how can I improve my oxygen levels?

Normal blood oxygen levels are greater than 95 percent, and oxygen levels below 90 percent are considered low blood oxygen, suggesting hypoxemia.

There are many ways to help you improve your oxygen levels. You could try adding plants such as the areca palm, snake plant, money plant or gerbera daisy to your home to naturally increase oxygen, or try natural air purifiers, such as salt lamps, peace lilies and bamboo charcoal.

Staying calm and practicing deep breathing exercises can lower stress levels and improve oxygen levels. When you’re relaxed, it’s easier to breathe, so consider giving meditation, yoga, writing in a journal or positive thinking exercises a try.

Exercise is important for everyone, especially for people with lung diseases. Even gentle forms of exercise such as Tai Chi and walking can improve your oxygen levels and boost your exercise tolerance.

Low Blood Oxygen and How it Affects the BodyDrinking enough water is a simple way to increase your blood oxygen levels. Water hydrates the body, thereby helping to increase the volume of blood available for the lungs to oxygenate.

A healthy diet can also improve your oxygen levels. Using herbs instead of salt can reduce bloating while still giving your food flavor. You can also try eating fresh, steamed vegetables such as spinach, potatoes, green beans and carrots. Remember to eat plenty of lean protein, too. Before trying a new diet, exercise or treatment plan, always discuss it with your doctor.

    Dear Dianna,

    Thanks for your question. Like you, many people with COPD have trouble with fatigue and energy levels. In conjunction with your deep breathing exercises, you could consider trying gentle stretches that you can do from a seated position. You could also try relaxation techniques such as writing in a journal and listening to gentle music. When you incorporate these techniques into your daily routine, you may notice more energy. Of course, it’s important to remember that increasing your energy levels takes time. It’s also important to talk with your doctor about your questions and concerns about your energy levels and what techniques would work best for you. We wish you the best.

    Best Regards,

    The Lung Institute

Because your doctor knows you and your health situation well, he or she will be able to best guide you.

    my right lung was damaged by 30 radiation after a lumpectomy in 2010.I cough a lot but the doctors save my lungs sound good. But I don’t feel like they are working right. I cough up lots of yellow mucus especially in arising and after meals or just any time. Use nebuliser 4 times a day.
    Albuterol 4s.Ipatropium 2s, & Budesonide 2s times a day.

    Hello, Jacques.
    I can answer one of your questions here in this forum–the Lung Institute does not yet operate a clinic in Canada.
    We don’t know whether the treatment would be covered by the Canadian health system. It seems that the best way to learn that is to contact a Canadian health system representative, and ask if, 1. they cover stem cell therapy and, 2., if they cover the therapy here in the United States.
    As for any questions about medications or exercise, we suggest you ask your doctor. No one knows your personal situation better than you and your physician, and we have no way of making those type of judgements in this forum.
    Our treatments require three consecutive days, after which you can return home. There is no need to return, unless you choose to have a booster treatment.
    If you would like more detailed information, please call our patient coordinators here in Tampa, Florida, at 1-(855) 313-1149. They’ll be happy to answer all of your questions much more effectively than I can.

    Best of Luck, and thanks for contacting us.

    I am Canadian, are you aware if the Canadian health system is paying at least a portion of the stem cells treatment. Also do you have a clinic in Canada ?
    What is the cost of a complete stem cells treatment for obtaining enough healthy efficient stem cells to not taking Spiriva medicine or any lungs medicine anymore ? Another question is do I will be able to breathing good enough to jog at moderate speed for one hour ?
    How long do I will have to stay at hotels before complete positive treatment and not come back to the clinic ?

    I appreciate the info. I’m really bad at raising money for stem cell treatment, but can manage my savings of about $2,000. Is there a treatment payment plan available for the balance?

    Dear Victor,

    Thank you for your question. In this article, we wanted to discuss how low blood oxygen affects the body. For people with a chronic lung disease, such as pulmonary fibrosis or COPD, low blood oxygen can be a challenge. However, we have written in-depth articles on pulmonary fibrosis as well. You can read more about pulmonary fibrosis by clicking here. We hope this is helpful for you, and we wish you the best.

    Kind Regards,
