Übelkeit und Erbrechen als evolutionäre Mechanismen der vielschichtigen Anpassungsreaktion an die Schwangerschaft

Abstract

Our new and previously existing data support the idea that NVP has been selected for by evolution, as a functional adaptation to vulnerable early pregnancy, which benefits mother and child. This assumption is supported by the correlation of NVP with a better foetal prognosis, the cross-culturally high prevalence and a favorable relation of low biological costs versus high effects. The benefit of NVP could be realised by nutritional change, increased social support, more passive and careful behaviour, earlier recognition of pregnancy and a positive influence on foetal development. To understand the functionality of NVP, one needs to consider the complex somato-psychoemotional interplay in the context of an environment of evolutionary adaptedness (EEA).

“… 8 It has also been suggested that, in evolutionary terms, NVP could have a protective effect in early pregnancy, realized by nutritional change, increased social support, more passive and careful behavior, earlier recognition of pregnancy and a positive influence on fetal development. 9 It may be no coincidence, therefore, that NVP is associated with fewer fetal deaths and higher birth weight. 10 , 11 …”
