Complications

Mild cases of ascariasis usually don't cause complications. If you have a heavy infestation, potentially dangerous complications may include:

• Slowed growth. Loss of appetite and poor absorption of digested foods put children with ascariasis at risk of not getting enough nutrition, which can slow growth.
• Intestinal blockage and perforation. In heavy ascariasis infestation, a mass of worms can block a portion of your intestine. This can cause severe abdominal cramping and vomiting. The blockage can even make a hole in the intestinal wall or appendix, causing internal bleeding (hemorrhage) or appendicitis.
• Duct blockages. In some cases, worms may block the narrow ducts of your liver or pancreas, causing severe pain.
