[Gastrointestinal diseases in pregnancy].

Abdominal complaints during pregnancy are frequent. In most instances, nausea and vomiting are a consequence of pregnancy and are considered indicators of a well-developing pregnancy. The growing uterus and hormonal changes during pregnancy often lead to gastroesophageal reflux and constipation. Serious gastrointestinal diseases such as intestinal obstruction or the exacerbation of a chronic inflammatory bowel disease during pregnancy are rare, but if suspected, often warrant immediate confirmation and aggressive therapy. Unnecessary delays are associated with an increasing mortality and morbidity.
