In the UK news this week is a story about morning sickness costing the NHS £60 million per year.
The article suggests that four out of five women in the UK suffer from nausea and many of them will seek medical advice. In fact, there may be as many as 80 ambulance callouts per day, related to nausea and vomiting in pregnancy.
Of course as the article suggests many women are reluctant to take medicines during pregnancy, including anti-sickness medication. But, as the article goes on it suggests that reluctance to seek help in the early stages may be a factor in becoming so poorly that it may be too hard to get symptoms under control even with medication.
