What's the differance in bronchiectasis vs asthma copd emphasima. what there similarities between the other disease's. i can't stop coughing at night?

Complicated: Bronchiectasis is due to chronic infection damaging the ends of bronchioles and creating a haven for chronic infection. Asthma is due to reactive airway disease making it difficult to get air out. COPD is a complex process and can involve emphysema and brochiectasis. See your doctor to figure out why you are coughing. Without more info cannot diagnose this.

That's a long answer: COPD is chronic obstructive pulmonary disease and is a clinical diagnosis. Emphysema is the destruction of alveoli, the small lung sacs. Asthma is narrowing of the bronchioles often with mucus production. Therefore, asthma and emphysema can be included in the diagnosis of copd. Bronchiectasis is abnormal dialation of the bronchioloes usually due to chronic or repeated infections.
