Pulmonology
Cystic Fibrosis
A genetic disease causing thick, sticky mucus buildup in the lungs and digestive tract, leading to life-threatening respiratory infections and malnutrition.
Pulmonary Tuberculosis
An airborne bacterial infection caused by M. tuberculosis that primarily affects the lungs, leading to granulomatous inflammation, cavitary lesions, and chronic respiratory symptoms.
Small Cell Lung Cancer
A very fast-growing, aggressive lung cancer strongly linked to heavy smoking, presenting centrally in the chest and often spreading early to the brain and other organs.
Bronchiectasis
Permanent structural dilation of airways due to chronic inflammation and recurrent infections.
Pulmonary Embolism
A life-threatening blood clot in the lungs that blocks blood flow, causing sudden shortness of breath and chest pain.
Sarcoidosis
An inflammatory disease where tiny collections of immune cells (granulomas) grow in the lungs, lymph nodes, and other organs, causing coughing and shortness of breath.
Idiopathic Pulmonary Fibrosis
A fatal disease where the lungs become progressively scarred and stiff for unknown reasons, making breathing extremely difficult.
Asthma
A chronic lung disease causing episodes of airway narrowing and mucus production, leading to wheezing and shortness of breath. Controlled with daily inhaled steroids.
Pleural Effusion
Buildup of fluid between the layers of tissue that line the lungs and chest cavity, commonly causing shortness of breath and chest pain.
Obstructive Sleep Apnea
A condition where the airway repeatedly collapses during sleep, stopping breathing and causing severe snoring, poor sleep, and daytime sleepiness.
Pneumothorax
Air trapped in the chest cavity outside the lung, causing the lung to partially or completely collapse, resulting in sudden chest pain and breathlessness.
Pulmonary Arterial Hypertension
A progressive disease causing severe narrowing of the lung arteries, leading to high pressure in the lungs and ultimately right-sided heart failure.
