Foreign bodies swallowed
Sometimes when you try to swallow, the swallowed substance "goes down the wrong way" and gets inhaled into your windpipe or lungs (aspirated). This occurs most often in children who are younger than 3 years and in adults who are older than age 50. When you do inhale a substance, coughing is a normal reaction of the body to clear the throat and windpipe. The cough is helpful and may clear up the problem. Inhaling a substance into your lungs can cause a lung inflammation and infection (aspiration pneumonia).
