What causes morning sickness?
Believe it or not, no one knows for sure. But symptoms are thought to be due to:
- High levels of pregnancy hormones
- Fluctuations in blood pressure
- Altered metabolism of carbohydrates
- Enormous physical and chemical changes triggered by pregnancy
0: The lucky few
It's possible to experience no morning sickness at all, but a 2010 medical study found that women who had no nausea or vomiting during their first trimester were three times as likely to miscarry than women who did. But if you're not feeling sick, don't panic. For one in ten women, this is the norm.
Mild morning sickness is a lot like a hangover. Nothing a steak 'n' cheese pie can't fix. Certain smells or foods can trigger nausea, but you'll stop short of vomiting. By week 13, the hangover vanishes and you can spend the rest of the pregnancy eating kale chips.
Sufferers experience constant nausea and occasional vomiting but thankfully, symptoms are mostly gone by the second trimester. You'll wake up starving and ill. Keep crackers by the bed so you can eat before you get up, and stock up on remedies containing ginger.
Spewing through the entire pregnancy - but not enough to be hospitalised - is the curse of those in the strong grip of morning sickness. Bad enough to put many women off a second pregnancy.
