Most pregnant women experience morning sickness during the first 20 weeks of pregnancy. Often, the symptoms are mild, but recurring, nausea and vomiting; but the condition can also lead to dehydration, weight loss, electrolyte imbalance and blood volume depletion, and many women with more severe forms of the condition present to emergency departments.
