Sugar stuck in the esophagus can usually be melted away, but care needs to be taken not to eat or drink heavily for a short period of time after getting stuck to avoid vomiting due to esophageal blockage. In addition, if the sugar lump is large, it is recommended to seek medical attention and remove it with the help of a doctor. Generally small pieces of sugar will not get stuck in the esophagus because most sugar products are smoother and can pass through the esophagus smoothly. If the individual sugar lump itself is larger, directly swallowed and stuck in the esophagus, but because sugar is a water-soluble food, oral saliva and esophageal secretions contain a lot of water, sugar will gradually dissolve under the action of both, and after the volume is reduced to a certain extent, it will enter the stomach from the esophagus. However, sometimes the sharp side of sugar will damage the mucous membrane of esophagus and cause discomfort to the patient. At this time, it is better not to eat, and then eat semi-liquid food after the discomfort is relieved, but foods with higher temperature should be avoided. In addition, if the sugar is large and stuck for a long time, or even causes the patient to cough and have difficulty breathing, it is recommended to seek medical attention and have it removed with the help of a doctor. Sugar stuck in the esophagus is mostly caused by talking or being frightened while eating sugar, resulting in the sugar contained in the mouth suddenly slipping into the esophagus, especially children have a narrow esophagus and are more likely to get stuck when eating sugar. Therefore, it is recommended to try to stay calm while eating and not to eat sugar cubes of excessive size to avoid the situation of getting stuck in the esophagus.
