Morning sickness
Morning sickness is a relatively common pregnancy discomfort, affecting between half and two thirds of women at some stage during their pregnancy. Morning sickness is most common during the first trimester and is often at its worst during the early part of the day, although it can be present at any time of the day or night. Typical symptoms include nausea and vomiting with varying degrees of severity.
Morning sickness will most often resolve itself within the first 12-14 weeks of pregnancy, however some women will experience symptoms into the second and even the third trimester. Usually morning sickness is not a danger to the mother or baby, however, severe morning sickness may result in weight loss or dehydration for the mother. In this instance it is important to seek medical attention immediately.
