Bronchiectasis is a disease that causes widening of parts of the airways in one's lungs. It is commonly caused by repeated respiratory infections, although there are genetic (cystic fibrosis) and other environmental causes as well. Common symptoms include chronic coughing, chest pain, and recurrent bouts of pneumonia. Treatment involves the use of antibiotics to curb infection and well as steroids to halt disease progression. There are other new treatments which have only recently been approved for use.
