Pedro Bial says he has emphysema linked to past smoking

Brazilian journalist and presenter Pedro Bial, 68, has revealed that he has emphysema, which he links to his years of smoking.

He has said he quit smoking 18 years ago and is receiving treatment.

Emphysema is a form of chronic obstructive pulmonary disease, or COPD, that permanently damages tiny air sacs in the lungs.

These air sacs help move oxygen into the blood and remove carbon dioxide, so damage can make breathing harder.

Symptoms can include shortness of breath, a persistent cough, phlegm and tiredness, and they may worsen over time.

There is no cure, but treatment can ease symptoms and help slow the disease; options can include inhaled medicines and, in some cases, respiratory physiotherapy or supplemental oxygen.

Stopping smoking and getting an early diagnosis can help limit further damage, and doctors may use breathing tests and scans to assess the condition.
