- Epidemiology
- Women's Health
Background:
- Nausea and vomiting are common in early pregnancy.
- The exact cause and prevalence require further investigation.
Purpose of the Study:
- To determine the prevalence of nausea and vomiting in early pregnancy.
- To explore potential etiological factors and impact on daily functioning.
Main Methods:
- An epidemiological survey was conducted.
- Data was collected from 500 consecutive antenatal patients.
Main Results:
- 76% of women experienced symptoms in the first trimester.
- Symptoms persisted beyond 12 weeks for 73% of affected women.
- Job efficiency was significantly impaired.
