Choking is a medical emergency that occurs when an object, such as food, becomes lodged in the throat, blocking the airway and making it difficult or impossible to breathe. Choking can be a life-threatening situation if not treated immediately.

Common causes of choking include eating too quickly or not chewing food properly, drinking alcohol before or during meals, eating while talking or laughing, and swallowing objects that are not meant to be eaten. Choking can also be caused by medical conditions that affect the throat or esophagus, such as gastroesophageal reflux disease (GERD) or tumors.

If you or someone you know is choking, the first step is to call for emergency medical assistance immediately. While waiting for help to arrive, you can try to help the person by performing the Heimlich maneuver or back blows.

To perform the Heimlich maneuver, stand behind the choking person and wrap your arms around their waist. Make a fist with one hand and place it just above their navel, with your other hand over your fist. Then, press sharply inward and upward with your hands, repeating until the object is dislodged.

To perform back blows, stand behind the choking person and place the heel of your hand between their shoulder blades. Then, give five sharp blows to the back, followed by five abdominal thrusts. Repeat until the object is dislodged.

It is important to note that if the person is unconscious, the first step is to begin CPR (cardiopulmonary resuscitation) and follow the steps recommended by emergency services until medical professionals arrive.
