RESUMEN
Nausea and vomiting are common experiences in pregnancy, affecting 70% to 80% of all pregnant women. Various metabolic and neuromuscular factors have been implicated in the pathogenesis of nausea and vomiting of pregnancy (NVP) and hyperemesis gravidarum (HG), an entity distinct from NVP. However, their exact cause is unknown. Consequently, treatment of NVP and HG can be difficult, as neither the optimal targets for treatment nor the full effects of potential treatments on the developing fetus are known. This article reviews the epidemiology, pathology, diagnosis, outcomes, and treatment of NVP and HG.

Capsule endoscopy (CE) has evolved in a few short years to become a first-line, noninvasive diagnostic technique for the small bowel. CE is now being utilized worldwide to assess patients for obscure gastrointestinal bleeding, possible Crohn's disease, celiac disease and small bowel tumors. The device is now used in tandem with balloon enteroscopy to direct therapeutic interventions. Alterations and improvements in CE have also led to the evaluation of both the esophagus and colon. It can be anticipated that in the near future pan CE of the entire GI tract will be performed, as well as possible tissue acquisition, drug delivery and therapeutic interventions.

Liver diseases in pregnancy may be categorized into liver disorders that occur only in the setting of pregnancy and liver diseases that occur coincidentally with pregnancy. Hyperemesis gravidarum, preeclampsia/eclampsia, syndrome of hemolysis, elevated liver tests and low platelets (HELLP), acute fatty liver of pregnancy, and intrahepatic cholestasis of pregnancy are pregnancy-specific disorders that may cause elevations in liver tests and hepatic dysfunction. Chronic liver diseases, including cholestatic liver disease, autoimmune hepatitis, Wilson disease, and viral hepatitis may also be seen in pregnancy. Management of liver disease in pregnancy requires collaboration between obstetricians and gastroenterologists/hepatologists. Treatment of pregnancy-specific liver disorders usually involves delivery of the fetus and supportive care, whereas management of chronic liver disease in pregnancy is directed toward optimizing control of the liver disorder. Cirrhosis in the setting of pregnancy is less commonly observed but offers unique challenges for patients and practitioners. This article reviews the epidemiology, pathophysiology, diagnosis, and management of liver diseases seen in pregnancy.
