Difficulty in Breathing : Causes, Types, Treatment and Symptoms

Difficult breathing, often referred to as dyspnea or shortness of breath, is a subjective condition in which a person feels unable to take in enough air or struggles to breathe comfortably. This might range from moderate discomfort during physical exercise to severe shortness of breath that disrupts daily activities or happens even at rest. Difficulty breathing should always be evaluated promptly, especially if it is sudden, severe, or accompanied by chest pain, bluish discoloration of the skin, fainting, or confusion.

Most Common Breathing Difficulties Symptoms:

• Shortness of breath or “air hunger”
• Rapid or shallow breathing
• A whistling or squeaky sound while breathing
• Sensation of discomfort or squeezing in the chest
• Blue-tinged skin, lips, or fingertips, evidence of low oxygen levels in the blood
• Use of accessory muscles or tripod positions
• Increased effort to breathe and nasal flaring
• Interrupted or irregular breathing pattern
• Cough, fatigue, or exhaustion
• Fever, chills, or sweating
• Dizziness, fainting, or rarely, chest pain
• Difficulty lying flat
• Anxiety or panic attack
• Swelling of the legs, feet, or ankles

Common, Uncommon or Underlying Causes of Breathing Difficulties

Difficulty breathing, or dyspnea, can be caused by a wide range of common, unusual, and underlying medical disorders that are commonly classified as respiratory, cardiac, neuromuscular, psychogenic, and systemic disorders. Breathing problems can be acute, recurrent, or chronic, lasting weeks to months. This wide spectrum of reasons mentioned below explains why breathing trouble is a symptom rather than a separate diagnosis.

• Respiratory cause: Asthma, COPD, pulmonary embolism, lung infection, tuberculosis, interstitial lung disease, pneumothorax, or lung infections
• Cardiac cause: Heart failure, heart attack, heart arrhythmias, pulmonary edema, valvular heart disease, pericardial tamponade, or pulmonary hypertension
• Neuromuscular cause: Obesity, spinal deformities, CNS or spinal cord dysfunction 
• Psychogenic cause: Hyperventilation syndrome, anxiety, or panic attack, vocal cord dysfunction
• Other systemic causes: Anemia, acute kidney failure, metabolic disorders, thyroid disorders, liver cirrhosis, severe allergic reaction, or sepsis
• Sudden causes: Choking, blood loss, carbon monoxide poisoning, or drug overdose
• Environmental causes: Pollutants like smoke from passive smoking, chemical inhalation, or living or working in dusty/moldy places

When to Seek a Specialist for Your Breathing Difficulty?

Under specific cases, it is critical to see a professional right away if you are having difficulty breathing in order to receive a fast diagnosis and treatment. If you have an experience, you should consult with an expert. Depending on the underlying reason, you may be directed to a pulmonologist (lung specialist), cardiologist (heart specialist), allergist, or neurologist. Early consultation can assist in minimizing problems and improving results by addressing significant illnesses such as asthma, COPD, heart failure, pulmonary embolism, and infections.

Visit your specialist if these difficulty breathing symptoms are present:

• Sudden, severe, or worsening difficulty in breathing
• When accompanied by chest pain, tightness, or pressure.
• Blue or grey lips, face, or fingertips
• Recurring shortness of breath
• A wheezing noise that does not go away
• Severe coughing spells accompanied by blood
• Palpitation or fainting spells
• Rapid or irregular heartbeat
• Making it difficult to speak in complete sentences
• Causes confusion, drowsiness, or fatigue
• Constantly waking up at night due to persistent or severe breathlessness
• Swelling of the face, tongue, or throat
• Recurring episodes of anxiety or panic attacks
• Rarely, after a long period of inactivity, an indication of a blood clot in the lung

Diagnostic Approach for Difficulty Breathing

The specialist-approved diagnostic strategy for trouble breathing (dyspnea) usually involves a systematic process that includes clinical evaluation, initial testing, and, if necessary, more expert investigations. Management is dependent on the underlying cause discovered throughout this thorough review. This organized diagnostic technique aids in the proper diagnosis and treatment of people with breathing difficulties.

Here are the specialist-approved diagnostic steps:

• Detailed medical history: Including onset, duration, triggers, associated symptoms (chest pain, cough, fever), past medical history (lung and heart diseases), smoking status, and risk factors.
• Physical examination: Check for abnormal breath sounds, heart murmurs, leg swelling, cyanosis, respiratory effort, and oxygen saturation.
• Chest X-ray: To identify lung infections, masses, pneumonia, pneumothorax, and fluid around the lungs or heart.
• Electrocardiogram (ECG): To assess heart rhythm, ischemia, or infarction.
• Blood tests: Full blood count, thyroid function, brain natriuretic peptide (BNP) for heart failure, and D-dimer for clot suspicion.
• Spirometry: Measures lung function and airflow obstruction/reversibility and helps diagnose asthma and COPD.
• Pulse oximetry: Non-invasive oxygen saturation monitoring.
• CT scan of the chest: For detailed imaging of lungs and chest structures, detecting embolism, interstitial lung disease, and tumors.
• Echocardiography: To evaluate heart function, valve disease, and heart failure.
• Ambulatory ECG monitoring: For arrhythmias contributing to breathlessness.
• Cardiopulmonary exercise testing: To assess exercise limitation.
• Additional tests: Bronchoscopy, allergy testing, and sleep studies based on clinical suspicion.

Types of Difficulty Breathing

Some common types of difficulty breathing include:

• Dyspnea: General sensation of difficulty breathing.
• Orthopnea: Trouble when sitting flat, and relief occurs when sitting or standing up.
• Paroxysmal nocturnal dyspnea: Sudden severe breathlessness at night.
• Trepopnea: Worsening of dyspnea in the side-lying position
• Platypnea: Shortness of breath occurring in the upright position and relieved when lying down.
• Tachypnea: An abnormally rapid breathing rate may indicate an underlying heart, lung, or metabolic illness.
• Bradypnea: An abnormally slow breathing rate may indicate neurological or drug-induced problems.
• Hyperventilation: Breathing faster or deeper than necessary, often leading to dizziness, tingling, or faintness.
• Breathing pattern disorders: Includes hyperventilation syndrome, thoracic breathing, forced abdominal expiration, and other issues.
• Apical or mouth breathing: Primarily mouth breathing, rather than normal diaphragmatic breathing,

How to Treat the Symptoms of Breathing Difficulty?

In order to prevent the recurrence or progression of the underlying issue, diagnosis and management of the root cause must always be combined with symptom management to address respiratory difficulties. This treatment involves measures to improve comfort and oxygenation and reduce distress.

For underlying causes, treatments & rehabilitative strategies include:

• Oxygen therapy: Provides supportive oxygen when oxygen levels are low to relieve hypoxia.
• Positioning: Making you sit upright or in a tripod position helps reduce the breathing load.
• Bronchodilators: Inhalers or nebulizers relax airway muscles in asthma or COPD.
• Anxiety management: Suggest calm reassurances and controlled breathing techniques if anxiety exacerbates dyspnea.
• Treating airway obstruction: Clearing foreign bodies or secretions in case of severe airway narrowing occurring.
• Non-invasive ventilation: Machines to support your breathing in cardiac or lung conditions.
• Certain medications: May be suggested for heart failure, inflammatory conditions, infections, or pulmonary embolism.
• Long-term oxygen therapy: For chronic lung disease with persistent low oxygen.
• Pulmonary rehabilitation: Educating about respiratory conditions and exercise training.
• Lifestyle modification: Avoid triggers, smoking cessation, and weight management.
• Treatment adherence: Controlling underlying disease with prescribed medication.
• Psychosocial support: Counseling or therapy when anxiety or panic disorder continues.

What if Difficulty Breathing is Left Untreated?

Early diagnosis and treatment are crucial for better outcomes and symptom control, as untreated difficulty breathing can lead to severe symptoms like chest pain, cyanosis, confusion, or fainting, requiring immediate medical attention to avoid serious complications and impact quality of life.

Some possible complications of an untreated difficulty breathing include:

• Reduces physical activity and social isolation: Leads to avoidance of activities and causes muscle weakness and conditioning.
• Progression to respiratory failure: Inadequate oxygen delivery and carbon dioxide removal leading to respiratory failure
• Cardiac complications: High risk of heart attack or stroke.
• Chronic hypoxia: Cognitive decline or organ failure due to low oxygen levels.
• Anxiety and panic disorders: Worsening psychological distress.
• Increased risk of infections: Increased susceptibility to pneumonia and other lung infections.
• Potentially fatal outcomes: Severe, untreated conditions such as pneumonia, pulmonary embolism, acute asthma, or respiratory depression may lead to life-threatening situations.
