Overview

Shortness of breath is typically the result of very strenuous exercise, obesity, extreme temperatures, and higher altitudes. Outside of these situations, shortness of breath is most likely a medical problem.

If you experience shortness of breath, especially when it is sudden or severe, you must see your doctor right away. 

Some individuals with problems in the respiratory system can feel shortness of breath just by performing normal activities such as walking to another room or simply getting out of a chair. You should see your doctor if you experience shortness of breath that is accompanied by:

  • Difficulty breathing when lying flat
  • Swelling in the ankles and feet
  • Cough, chills, and high fever
  • Turning blue of lips or fingertips
  • Wheezing, which is the abnormal whistling type of sound when breathing in or out
  • Stridor, which is a high pitched noise when breathing
  • Worsening of pre-existing shortness of breath after using inhalers
  • Breathlessness that will not go away even after 30 minutes of rest.

A healthy adult breathes in and out about 20 times a minute, which is about 30,000 breaths each day. After a vigorous workout or when experiencing a common cold, you might experience shortness of breath from time to time, but generally, you should never feel short of breath. 

If you experience sudden and severe trouble catching your breath, you should immediately call the emergency medical service, especially when it is accompanied by nausea or chest pain.

Shortness of breath is quite a common symptom. While it could be related to a serious illness, it also may be the result of being physically out of shape.

Shortness of breath may be associated with the following serious conditions:

  • Chronic obstructive pulmonary disease or COPD
  • Asthma
  • Anemia
  • Heart diseases such as heart attack or heart failure
  • Pulmonary embolism or blood clots in the lungs.

Shortness of breath is the inability of getting enough air to breathe. It can come slowly or suddenly over weeks or months. The condition may occur when:

Causes of Shortness of Breath

  • Heart failure
  • Pneumothorax or collapsed lung
  • Pneumonia and other pulmonary infections
  • A blood clot in an artery in the lung or pulmonary embolism
  • Obstruction in the upper airway
  • Sudden loss of blood

In the case of chronic shortness of breath, one that has lasted for weeks or longer, the condition is usually caused by:

  • Asthma
  • Chronic obstructive pulmonary disease or COPD worsening of symptoms
  • Heart dysfunction
  • Deconditioning
  • Obesity
  • Interstitial lung disease
  • Accumulation of fluid around the lungs or pleural effusion

Several health conditions can also make it difficult to get enough air, including:

Lung problems

  • Croup, which is common in young children
  • Inflammation of the membrane surrounding the lungs or pleurisy
  • Lung cancer
  • Excess fluid in the lungs or pulmonary edema
  • Scarred and damaged lungs or pulmonary fibrosis
  • High blood pressure within the blood vessels in the lungs or pulmonary hypertension
  • Collections of inflammatory cells in the body or sarcoidosis
  • Tuberculosis

Heart problems

  • Problem with the heart muscle or cardiomyopathy
  • Heart failure
  • Inflammation of the tissue around the heart or pericarditis

Other problems

  • Anemia
  • Broken ribs
  • Anxiety disorders
  • Choking
  • Swelling of the lid of the windpipe or epiglottitis

Diagnosis and Treatment of Shortness of Breath

When you complain of shortness of breath, the doctor will examine you. Part of the examination is listening to your lungs. The doctor might ask you to have a lung function test, or spirometry, to determine how air you can blow in and out of your lungs, as well as how fast you can do it. This test will help diagnose if you have asthma or COPD. 

The doctor might conduct other tests, including:

  • Pulse oximetry – The doctor clips a device to your finger or ear lobe to measure the amount of oxygen in your blood.
  • Blood tests – These tests will show if you an infection or anemia. It can also check for a blood clot or fluid in your lungs.
  • Electrocardiogram – This test measures the electric signals from your heart. This checks if you have a heart attack and also to find out how fast your heart beats and if there is a healthy rhythm.
  • Chest X-ray or a CT scan – These tests can see if you have pneumonia, a blood clot in your lungs, or other lung diseases. A CT scan puts together several X-rays from various angles to make a complete picture.

If you have asthma, the doctor may prescribe that you use an inhaler during a flare. Fluid in the lungs needs to be drained by the doctor.
