COPD is a group of lung diseases that make it difficult to breathe out air from the lungs due to narrow airways. The two main types are chronic bronchitis, which involves long-term coughing, and emphysema, which damages the lungs over time. COPD progresses through four stages from mild to very severe. Symptoms include shortness of breath, chronic cough, and sputum production that varies daily. The primary cause is tobacco smoking, but other irritants like secondhand smoke or air pollution can also lead to COPD. Diagnosis involves consideration of risk factors like smoking history and exposure to lung irritants. Pathology shows the evolution of harmful changes in lung function starting with airway and sac damage

and even fumes from gas burned for cooking in poorly
ventilated bulidings can also lead to COPD discover more
COPD trigger her.
Diagnosis;
*You are a smoker or have smoked in the past.
*You are exposed to Lung irritants on the job.
*You are exposed to a lot of secondhand smoke.
*You have a family history of COPD.

8. *You have asthma or other respiratory conditions.
*You take over the counter or prescription medications.
Pathology;
*Pathophysiology is the evolution of adverse Functional
changes associated with a disease. For people with COPD
this starts with demage to the airways and tiny air sacs in
the lungs symptoms progress from a cough with mucus to
difficulty breathing.
