If a baby swallows a plum kernel, the first thing to know is the shape of the kernel. If the shape of the kernel is relatively round and smooth and not sharp, it may follow the food to be expelled from the body through the anus through the stool. However, if the plum nucleus is sharp or if you don’t know what shape it is, you can go to the hospital for examination and X-ray are able to understand. If conservative treatment, observe the child’s physical condition, if there is no abdominal pain, nausea, vomiting or diarrhea, etc., the main focus is to observe the stool every day, and if it is discharged from the body, no special treatment is needed. However, if it is not discharged for a long time and there is abdominal pain and other symptoms, it is necessary to understand where the plum nucleus is located, and if it remains in a certain location for a long time, it may be necessary to remove the plum nucleus by means of gastroscopy or colonoscopy.
