When something interferes with the ability to take in air, breathing can become labored. For example, a choking incident can cause the airways to block up partially.
A foreign object inhaled into the lungs may also cause heavy breathing. If a foreign object in the airway is a possibility, people should seek emergency medical care, even if they are still able to breathe.
Other symptoms that may accompany a respiratory system obstruction include:
* A rattling sensation in the chest or throat
* Burning in the throat or chest
* Feeling as if something is scraping the throat or back of the mouth
