What Tests Should Be Done for Shortness of Breath? Dyspnea

Shortness of breath is usually mild and temporary. However, sometimes it indicates an underlying chronic condition that can cause health complications. In such cases, early diagnosis is important. 

Consult a doctor for shortness of breath if the condition:

• Interferes with daily activities
• Worsens or does not go away
• Occurs even when at rest
• Is accompanied by fever, chest pain, excessive sweating, or cough
• Leads to bluish or grayish discoloration of the skin, nails, or lips

Symptoms that may accompany shortness of breath include:

• Labored breathing
• Shallow or rapid breathing
• Tightness in the chest
• Wheezing or coughing
• Heart palpitations
• Feeling of being suffocated

Shortness of breath has many causes, depending on whether it is acute or chronic. Acute dyspnea occurs over hours or days, whereas chronic dyspnea occurs over weeks or months.

Acute causes:

• Allergies
• Anxiety
• Extreme temperatures
• Chest injury
• Infection
• Choking
• Heart attack
• Pulmonary embolism (blood clotting in one or more arteries in the lungs) 
• Side effect of a medications (such as statins or beta-blockers)

Chronic causes:

• Asthma
• Obesity
• Chronic kidney disease
• Lung disease (chronic obstructive pulmonary disease and damage to lung tissues due to smoking, tumors, or  lung cancer)
• Poor cardiovascular health (due to poor circulation, fluids get accumulated in the lungs, making it difficult to breathe)
• Sedentary lifestyle

Triggers such as environmental pollutants can play a role in shortness of breath. Exposure to the following can trigger frequent episodes of dyspnea:

• Chemicals
• Dust
• Tobacco smoke
• Fumes
• Allergens such as mold or pollen

People who are at a higher risk of dyspnea include:

• Pregnant women: Pregnancy tends to alter the breathing capacity of women, causing about 20% decrease in lung volume.
• Elderly and those with chronic diseases: Older people and people with chronic health conditions or at advanced stages of diseases are at a higher risk of developing the symptom.
• Infants: Pediatric emergencies such as upper respiratory system conditions can lead to dyspnea. Inflammation of the epiglottis, inhaling foreign objects, and croup are also common causes of shortness of breath in infants.

Treatment of shortness of breath depends on the cause of the condition. Shortness of breath can be treated at home in some cases. However, because the condition can cause serious complications such as organ damage and cognitive impairment if not treated properly, it is important to consult a medical professional for proper diagnosis and treatment.

Medical treatment

In serious cases, your doctor may recommend:

• Oxygen therapy: Receiving extra oxygen through the nostrils to ease breathing
• Medications: Drugs called bronchodilators can help relax the airways and alleviate symptoms of asthma and COPD

Home remedies

Home remedies can help alleviate symptoms if the condition is not caused by a medical emergency:

• Pursed lip breathing: This breathing technique helps control shortness of breath caused by chronic obstructive pulmonary disease (COPD), hyperventilation, or panic attacks. Relax your shoulders and neck muscles and breathe in through your nose. Hold your breath for 2 seconds. Purse your lips as if you are about to whistle and then exhale slowly.
• Diaphragmatic breathing: Diaphragmatic breathing can help you manage shortness of breath caused by COPD. Sit on a chair with your shoulders, neck, and head muscles completely relaxed. Place a hand on your belly and inhale slowly through your nose. Tighten your stomach muscles and exhale through pursed lips. Continue for 5 minutes.
• Sitting position: Sitting forward in certain positions help relax your body and make breathing easier by creating more space in the chest cavity. Sit on a chair and lean your chest forward slightly. Relax your neck and shoulder muscles and inhale and exhale slowly. Supporting yourself with a pillow can make the breathing process more comfortable.
• Sleeping position: Lay on your side with a pillow between your legs and keep your head elevated. This position helps relax the airways, making breathing easier.

Lifestyle changes

Lifestyle changes can help you manage symptoms of dyspnea and prevent them from recurring: 

• Eat a balanced diet
• Maintain a healthy weight
• Quit smoking and avoid passive smoke
• Avoid environmental triggers
• Build endurance for intense workout sessions
• Make adjustment when traveling to high altitude regions
