Some 70 percent of women experience nausea within the first two months of
pregnancy and about half experience vomiting. These symptoms generally begin
within four weeks after conception and subside by nine or ten weeks. Nausea and
vomiting last throughout pregnancy in 10 to 15 percent of women. Severe or
prolonged nausea and vomiting are not considered normal and should be checked
out by your health-care provider.
Women who experience nausea or nausea
and vomiting early in pregnancy are more than 60 percent less likely to miscarry
than women who do not experience either nausea or vomiting. Increasing hormone
levels that are thought to prompt nausea and vomiting may be responsible for the
reduced risk miscarriage.
It is preferable to "Eat through" your nausea
and vomiting rather than to lose weight.
