RELATION BETWEEN HELICOBACTER PYLORI SEROPOSITIVITY AND HYPEREMESIS•GRAVIDARUM

Abstract

Nausea and vomiting of pregnancy, commonly known as" morning sickness " affects approximately 50% to 90% of all pregnant women in the first trimester. The typical onset is between 4-8 weeks of gestation, with symptoms continuing until .14-16 weeks. The exact cause of hyperemesis gravidarum is unknown however many theories have been propounded. H. Pylori is curved or spiral shaped, Gram negative, non­ capsulated non spore-forming bacillus. The organism measures (o.5-1) urn. in width and (2.5-5.0) urn. in length. Helicobacter pylorus plays a major role in abdominal symptoms and gastro-duodenal pathology. An association between infection with H. pylori and hyperemesis gravidarum may be present.
