### 3. Why it Causes Continuous Vomiting
In mild cases, people have no symptoms. However, in heavy infestations—especially in children, whose intestines are very narrow—a massive cluster of worms can knot together.
This creates a literal **intestinal obstruction** (a complete physical blockage). Because food and fluids cannot pass normally through the digestive tract, the body’s natural reflex is to violently reject everything, leading to the severe, continuous vomiting and acute abdominal pain described in stories like the one in **1000029637.jpg**.
### 4. Treatment and Prevention
* **Medication:** In most standard cases, a simple oral course of anti-parasitic medications (like Albendazole or Mebendazole) quickly kills the worms, which are then passed naturally out of the body.
* **Surgery:** Surgery, like the one implied by the surgical tray in **1000029637.jpg**, is only reserved for emergency situations where the bowel is completely blocked, perforated, or at risk of rupturing.
* **Prevention:** The best defense is simple hygiene: thorough handwashing with soap, washing and peeling raw fruits and vegetables, and ensuring access to clean, treated drinking water.
