Heterophilic

Hookworm duodenitis syndrome is also known as Griesinger syndrome. First discovered by Italian scholar Dabin in 1843. Since then, it has been reported all over the world, mainly distributed in temperate regions (between 35 ° north latitude and 30 ° south latitude). China is also one of the most frequent regions. The first symptoms are increased gastric appetite and weight loss, upper abdominal discomfort and pain, abdominal distension after eating. Loss of appetite in the later stages may be nausea, vomiting, constipation, or diarrhea, and heteroacidophilia.
