•     BRONCHITIS
•     Bronchitis is an infection of the main airways of the lungs (bronchi), causing them to become irritated and inflamed.

• Emphysema is a type of chronic obstructive pulmonary disease. The air sacs in the lungs become damaged and stretched. This results in a chronic cough and difficulty breathing. Smoking is the most common cause, but emphysema can also be genetic.

• The cause of emphysema is usually long-term exposure to irritants that damage your lungs and the airways. In the United States, cigarette smoke is the main cause. Pipe, cigar, and other types of tobacco smoke can also cause emphysema, especially if you inhale them.

• symptoms arise:

• Shortness of breath, especially during light exercise or climbing steps
• Ongoing feeling of not being able to get enough air
• Long-term cough or “smoker’s cough”
• Wheezing
• Long-term mucus production
• Ongoing fatigue

• PNEUMONIA

• Pneumonia is an infection in one or both lungs. Bacteria, viruses, and fungi cause it. The infection causes inflammation in the air sacs in your lungs, which are called alveoli. The alveoli fill with fluid or pus, making it difficult to breathe.Aug 20, 2019
