How does enterobius vermicularis cause anorexia?
I don't know if it causes anorexia itself, because anorexia is a mental disorder. It is characterized by the refusal of maintaining a healthy weight, and the person usually has low self-esteem. Enterobius vermicularis causes itching, abdominal pain, etc. It might have anorectic properties, which means it can cause loss of appetite, but that doesn't necessarily cause anorexia. I'm not a professional, so I can't tell you for sure, but the articles I found on Google about this worm defined anorexia as "loss of appetite" (but there's more about anorexia, as I said above.)
most infections with enterobius vermicularis aka pinworms is usually asymptomatic (without symptoms) the most common symptom you'll see with this infection is itching around the anus. occasionally the amount of worms in the body can be so great that you may get abdominal pain, nausea, and vomiting. when that is the case, you won't feel like eating (anorexia). to add on to Arnascar's comment, anorexia is a term used for loss of apetite. anorexia nervosa is used to denote the mental disorder which has anorexia as a symptom among other things.
