Differential Diagnosis for Squicky Noise While Breathing

  • Single most likely diagnosis
    • Asthma: A squicky noise while breathing can be indicative of wheezing, a common symptom of asthma. This condition is characterized by inflammation and constriction of the airways, leading to difficulty breathing and wheezing sounds.
  • Other Likely diagnoses
    • Chronic Obstructive Pulmonary Disease (COPD): Similar to asthma, COPD can cause wheezing and breathing difficulties due to the obstruction of airflow in the lungs.
    • Bronchitis: Inflammation of the bronchial tubes can lead to wheezing and a squicky noise while breathing, especially if the condition is chronic.
    • Pneumonia: In some cases, pneumonia can cause wheezing and breathing difficulties, particularly if the infection is severe or affects the airways.
  • Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
    • Foreign Body Aspiration: If a foreign object is lodged in the airway, it can cause a squicky noise while breathing and is a medical emergency that requires immediate attention.
    • Epiglottitis: Inflammation of the epiglottis can cause severe respiratory distress and a squicky noise while breathing, and is a life-threatening condition if not treated promptly.
    • Pulmonary Embolism: Although less common, a pulmonary embolism can cause sudden onset of wheezing and breathing difficulties, and is a potentially fatal condition if not diagnosed and treated promptly.
  • Rare diagnoses
    • Cystic Fibrosis: A genetic disorder that affects the respiratory and digestive systems, cystic fibrosis can cause wheezing and breathing difficulties due to the buildup of thick mucus in the lungs.
    • Bronchiectasis: A condition characterized by the permanent enlargement of parts of the airways, bronchiectasis can cause wheezing and breathing difficulties, as well as a squicky noise while breathing.
    • Tracheomalacia: A rare condition where the trachea is soft and floppy, tracheomalacia can cause a squicky noise while breathing due to the collapse of the airway.
