Welcome to HCM,
Thanks for the query.
Your father might have COPD
This limits airflow to and from the lungs, causing shortness of breath
). , this limitation is poorly reversible and usually gets progressively worse over time.
The diagnosis of COPD is dyspnea, chronic cough
or sputum production, and a history of exposure to risk factors for the disease such as regular tobacco smoking
No single symptom or sign can adequately confirm or exclude the diagnosis of COPD.You should go for X-rays and other pulmonary tests your physician suggests and get medication accordingly.
Good luck for him and feel free for any suggestion.
