Most of the plastic fragments can be excreted by themselves, while some cannot be excreted by themselves. If the plastic fragments are small, most of them can be discharged through gastrointestinal peristalsis, along with the feces. However, some of the larger fragments are likely to be blocked in the digestive tract, which may lead to obstruction of the digestive tract in severe cases, and need to be discharged through enemas or even surgery. If the plastic fragments are small, you can eat more vegetables and fruits, increase exercise, promote gastrointestinal motility, and facilitate the discharge of the fragments. Plastic contains substances that are harmful to the human body, so you need to pay attention to your diet to avoid accidental ingestion. If the fragments are large, or abdominal pain, nausea, vomiting and other discomforts need to consult a doctor in a timely manner, under the guidance of the doctor to actively treat.
