Asthma is an inflammation of airways or breathing passages in your lungs.
The main symptoms of asthma are:
- Tightness in chest
There are other factors which can influence these symptoms.
Q. What is the difference between asthma and Chronic Obstructive Pulmonary Disease (COPD)?
COPD is characterised by airflow obstruction that is only partially reversible, or completely non-reversible. People with partial reversibility don’t usually experience the same level of improvement with medications as those with asthma. A person with COPD will always have a lung function result lower than normal, even when not sick with an episode / flare-up (exacerbation). As indicated by the name, COPD is a chronic disease. It is always there even when you’re feeling well and it does not go away.
