Familial emphysema is a lung problem that induces difficulties in breathing. The air sacs in the lungs are compromised in persons who have emphysema. The inner walls of the air sacs deteriorate and tear over time, resulting in bigger air gaps rather than numerous small ones. This decreases the surface of the lungs and, as a result, the number of oxygen that enters the blood.
When you exhale, the injured alveoli don’t function properly, trapping old air and preventing fresh, oxygen-rich air from entering. Chronic bronchitis affects the majority of patients with familial emphysema. Chronic bronchitis is a condition in which the passages that deliver air to your lungs become inflamed, resulting in chronic cough.
