Emphysema is a chronic lung disease that causes shortness of breath and difficulty breathing. It is characterized by damage to the air sacs in the lungs, which leads to the lungs becoming less elastic and making it harder to breathe. Emphysema is often caused by smoking or long-term exposure to air pollution or chemical fumes. Symptoms of emphysema include coughing, wheezing, and chest tightness. Treatment typically involves quitting smoking, using inhalers or medications to help with breathing, and in severe cases, oxygen therapy or surgery may be necessary.

Emphysema is a chronic respiratory disease that causes shortness of breath. It is a type of Chronic Obstructive Pulmonary Disease (COPD).
Definition:
Emphysema is a condition characterized by the destruction of the alveoli, the small air sacs in the lungs where gas exchange occurs. As the alveoli are damaged, they lose their elasticity and become enlarged. This reduces the surface area available for gas exchange, making it difficult for oxygen to enter the bloodstream and for carbon dioxide to be removed.
Causes:
The most common cause of emphysema is smoking, which releases harmful chemicals that damage the alveoli. Other risk factors include:
- Air pollution
- Exposure to dust and chemicals
- Certain genetic conditions
- Aging
Symptoms:
Emphysema typically develops gradually, and symptoms may not be noticeable until significant lung damage has occurred. Common symptoms include:
- Shortness of breath, especially during exertion
- Wheezing
- Coughing
- Fatigue
- Weight loss
- Bluish discoloration of the skin or lips (cyanosis)
Diagnosis:
Emphysema is diagnosed through a combination of symptoms, medical history, and tests such as:
- Pulmonary function tests
- Chest X-ray
- CT scan
- Bronchoscopy
Treatment:
There is no cure for emphysema, but treatment can help manage symptoms and slow disease progression. Treatments may include:
- Quitting smoking
- Medications (bronchodilators, inhaled steroids, antibiotics)
- Oxygen therapy
- Pulmonary rehabilitation
- Surgery (in severe cases)
Complications:
Untreated emphysema can lead to several complications, including:
- Respiratory failure
- Heart failure
- Pneumothorax (collapsed lung)
- Infections
- Death
