History

Early symptoms of ascariasis, during the initial lung migration, include cough, dyspnea, wheezing, and chest pain. This may be seasonal after rains in some countries, such as Saudi Arabia.

Abdominal pain, distension, colic, nausea, anorexia, and intermittent diarrhea may be manifestations of partial or complete intestinal obstruction by adult worms.

Jaundice, nausea, vomiting, fever, and severe or radiating abdominal pain may suggest cholangitis, pancreatitis, or appendicitis.

Physical

Rales, wheezes, and tachypnea may develop during pulmonary migration, particularly in persons with a high worm burden. Urticaria and fever may also develop late in the migratory phase.

Abdominal distension is nonspecific but is common in children with ascariasis.

Abdominal tenderness, especially in the right upper quadrant, hypogastrium, or right lower quadrant, may suggest complications of ascariasis.

Evidence for nutritional deficiency due to ascariasis is strongest for vitamins A and C, as well as for protein, as indicated by albumin and growth studies in children observed prospectively. Some studies have not confirmed nutritional or developmental delay due to ascariasis.
