Complications
By Mayo Clinic staffTypical cases of morning sickness don't pose risks for mother or baby. However, if you're underweight before pregnancy and morning sickness prevents you from gaining a healthy amount of weight during pregnancy, your baby may be born underweight. Rarely, frequent vomiting may lead to tears in the tube that connects the mouth to the stomach (esophagus).
