Loss of Appetite

When a pinworm infection is substantial with many threadworms in the intestine, it can cause loss of appetite, which is medically known as anorexia. People may have little interest in eating, which can lead to weight loss.

Lack of appetite may be caused by associated feelings of nausea. Some research suggests that appetite and weight loss could be a bodily response to parasites in the gut, as the body tries to fight the parasitic infection.6Worthington, John J., et al. ‘Adaptive Immunity Alters Distinct Host Feeding Pathways during Nematode Induced Inflammation, a Novel Mechanism in Parasite Expulsion.’ PLoS Pathogens, vol. 9, no. 1, 17 Jan. 2013, p. e1003122
