Medically Reviewed By Thomas Johnson, PA-C

Labored breathing can result from many conditions. Some causes, like physical exertion, are easily identifiable and treatable. Other causes, such as pneumonia or congestive heart failure, may be more severe. While “labored breathing” is not a medical term, it generally indicates breathing that requires more effort than usual.

Treatment for labored breathing varies depending on the cause. Some people may only need to avoid triggers, such as allergens. However, others may require more intensive medical treatment.

There are many causes of labored breathing. Some are short-lived, while others may be chronic heart and lung conditions. Identifying and managing the cause of your labored breathing will contribute to a positive quality of life.

  • Panic attack: A panic attack can create Trusted Source National Institute of Neurological Disorders and Stroke Governmental authority Go to source  feelings of being unable to breathe.
  • Asthma: People with asthma can experience narrowing and inflammation of the air passages. These symptoms increase airway resistance and make breathing more difficult.
  • Chronic obstructive pulmonary disease (COPD): COPD involves incurable and progressive lung deterioration, leading to breathing difficulties.
  • Pneumonia: Pneumonia causes fluid or pus to fill the air sacs in the lungs. This condition develops due to bacterial, viral, or fungal infections.
    • COVID-19: One consequence of COVID-19 is severe pneumonia that may require mechanical ventilation and high levels of oxygen support.
  • Congestive heart failure: In congestive heart failure, complex structural changes in the heart lead to Trusted Source PubMed Central Highly respected database from the National Institutes of Health Go to source an inability to pump effectively. Decreased pumping can stretch the heart walls and allow fluid to back up into the lungs, making breathing difficult.
  • Lung cancer: Lung cancer can cause breathing difficulties and other serious symptoms.

This initial exam will help your doctor determine any necessary testing to pinpoint the cause of your labored breathing.

  • spirometry, which assesses your lung capacity
  • diffusion capacity, which evaluates the effectiveness of gas exchange in the lungs
  • respiratory muscle pressure, which helps doctors assess how strong your breathing muscles are

More invasive tests may be necessary, including biopsy, bronchoscopy, and thoracentesis. Your doctor will discuss your testing and treatment plan details with you.

What are the treatments for labored breathing?

Treatment for labored breathing depends on your diagnostic test results. You may receive anti-inflammatory medications, oxygen therapy, or continuous positive airway pressure equipment to use at home.

Other treatments will be more specific to the underlying cause of your labored breathing. For example, lung cancer may require chemotherapy, radiation therapy, or surgery. People with asthma may need bronchodilator medication to help widen their airways.

In addition, your doctor may refer you to pulmonary rehabilitation services to improve your lung health. These programs provide interdisciplinary teams that include doctors, nurses, respiratory therapists, and nutritionists.


One of the most important things you can do to help your labored breathing is to avoid exposure to pollutants and tobacco smoke. If you smoke, quitting is essential.

If labored breathing occurs when lying flat, try sleeping in a semi-reclined position. You can use a recliner or a wedge pillow to achieve this position.

What is the outlook for people with labored breathing?

The outlook for people with labored breathing depends on the underlying cause. Some conditions that cause labored breathing are self-limiting or relatively minor, while others may be life threatening.

Seeking treatment from a medical professional and following your treatment plan can help improve your outlook.

When should you see a doctor about labored breathing?

If you develop labored breathing without an identifiable cause, contact your doctor. You may be developing a serious respiratory condition.

If labored breathing occurs with other severe symptoms, such as chest pain, pale lips, or pale nail beds, call 911 or seek immediate medical attention.
