why do we feel hiccup or chcking sensation while eating food ?
Normally when we eat, a tiny flap present in our wind pipe closes and prevents the food from entering the respiratory pathway but when we eat in a hurry the flap gets lesser time to close the windpipe. Consequently, some of the food particles enters the wind pipe. This creates a hindrance in the movement of air in windpipe and results in coughing, hiccups or choking sensation.
