Nausea and vomiting in early pregnancy

The majority of women suffer some form of sickness in early pregnancy. Although the theories relating to this condition and the remedies which have been tried are many and varied, there is still little known about the real causes of this disorder. Many therapeutic regimes recommend a high carbohydrate diet and it would seem appropriate to investigate further the possible role of nutritional factors in the aetiology as well as in the treatment of pregnancy sickness.
