influenza (flu) complications

possible problems from the flu include:
- pneumonia, which is an infection of the lungs. it rarely causes death in young, healthy people. but it can often be life-threatening in older adults, people who have other diseases, and pregnant women.
- bronchiolitis. this is an inflammation of the small air passages. it affects infants and is the leading cause of serious lower respiratory illness.
- sinusitis. this means the mucous membranes that line the inside of the nose and facial sinuses become infected and inflamed.
- croup. croup is a swelling or blockage in the windpipe. it causes hoarseness, a barking cough, a high-pitched sound when breathing in, and trouble breathing.
- chronic obstructive pulmonary disease (copd) symptoms may get worse.
- inflammation of the heart muscle, the sac around the heart, or other muscles.
