Chronic obstructive pulmonary disease (COPD) is a progressive lung disease that makes breathing difficult. It is characterized by long-term damage to the airways (bronchitis) and the air sacs (emphysema), leading to restricted airflow.
read more about chronic obstructive pulmonary disease ...The cause is long-term exposure to lung irritants, with cigarette smoking being the greatest risk factor. The irritants cause inflammation and permanent damage to the airways and the delicate lung tissue.
Symptoms include chronic coughing with mucus production, shortness of breath, and wheezing. These symptoms worsen during exertion and can progress over time. Fatigue, chest tightness, and frequent respiratory infections are common. In advanced cases, lips or fingertips may turn bluish due to low oxygen levels. Flare-ups can be triggered by air pollution, smoke, or respiratory infections, leading to sudden worsening of breathing difficulty.
COPD can impact eye health due to chronic coughing. The forceful, repetitive action of severe coughing can increase pressure in the head, leading to ruptured small blood vessels on the eye's surface (subconjunctival hemorrhage), which causes noticeable redness.
Treatment focuses on managing symptoms and slowing progression. Strategies include bronchodilator medications (to open airways), inhaled steroids (to reduce inflammation), oxygen therapy, and pulmonary rehabilitation (exercise and education).
Smoking cessation is the single most effective way to slow the progression of COPD. Quitting smoking stops the inflammation and ongoing damage to the lung tissue.
No, the damage to the lungs is permanent, but treatment can control symptoms and slow the disease's progression.
Chronic bronchitis is a specific form of airway damage that is a component of the broader term COPD.
COPD incidence in women is rising, and women may be more susceptible to the disease's effects at lower lifetime smoking levels.
Seek urgent care if you experience a sudden "exacerbation", increased shortness of breath or a change in the color of your phlegm. For patients with COPD, supplemental oxygen may be prescribed based on pulse oximetry or arterial blood gas tests to protect your heart and brain.
