You may have several accompanying symptoms with dyspnea. These additional symptoms can help you and your doctor diagnose its underlying cause. If you experience a cough, the dyspnea may be caused by a condition in your lungs. If you feel the symptom as chest pains, the doctor may test for heart conditions.

  • weight loss
  • crackling in the lungs
  • wheezing
  • night sweats
  • swollen feet and ankles
  • labored breathing when lying flat
  • high fever

Treatments

How is dyspnea treated?

Dyspnea can usually be treated by identifying and treating the condition that is causing it. During the time it takes for your doctor to diagnose the condition, you may receive interventions like oxygen and ventilation assistance to relive the symptom.

Treatments for dyspnea may include:

  • removing the airway blockage
  • eliminating mucus
  • reducing airway inflammation
  • alleviating the body’s hunger for air

Your doctor may prescribe medications to relieve symptoms. These may include steroids for asthma, antibiotics for pneumonia, or another medication related to your underlying condition. You may also need supplemental oxygen. In some cases, surgical intervention may be necessary to alleviate dyspnea.

There are additional treatments for dyspnea that go beyond medical interventions. Your doctor may recommend that you try breathing exercises. These can strengthen your lung functioning as well as help you combat dyspnea when it arises in your daily life.

If you experience dyspnea chronically, you should discuss lifestyle modifications that may alleviate it. These changes may reduce the occurrence of dyspnea and include:

  • losing weight
  • treating medical conditions
  • quitting smoking
  • avoiding environmental triggers like allergens and toxic air
  • staying in low-elevation areas (lower than 5,000 feet)
  • monitoring any equipment or medications you may be using
