Choking is characterized by coughing, difficulty in swallowing, difficulty in breathing, etc. It is recommended to eat slowly to avoid choking. 1. Coughing: Choking sometimes leads to partial obstruction of the airway, and the body will reflexively cough in order to clear the airway, so choking may show symptoms of coughing. 2. Difficulty in swallowing: when choking is slight, the choked food obstructs the esophagus, which is not conducive to food swallowing, therefore, the symptoms of dysphagia will be manifested after slight choking. 3. Difficulty in breathing: Severe choking may block most of the airways, resulting in the patient not being able to breathe normally, and even showing symptoms such as purple color and blurred consciousness. The symptoms of choking include coughing, difficulty in swallowing, difficulty in breathing, etc. If you have any problems, you need to go to the hospital in time and take different relief or first aid measures according to different symptoms.
