    What is (are) Choking ?
    ### Response:
    Food or small objects can cause choking if they get caught in your throat and block your airway. This keeps oxygen from getting to your lungs and brain. If your brain goes without oxygen for more than four minutes, you could have brain damage or die.    Young children are at an especially high risk of choking.
