What it is

Pregnancy raises requirements for a handful of nutrients — folate, iron, iodine and calcium in particular — well before it meaningfully raises calorie needs. Folic acid ideally starts before conception, because the neural tube forms in the first weeks. Food safety matters too, since a few infections carry more risk during pregnancy.

What to look for

Nausea in the first trimester is common and usually settles by around week 14

Heartburn and constipation are common later on

Concerning: vomiting that prevents keeping any fluid down

Sensible things to do at home

  • Take the prenatal supplement your doctor recommends, daily
  • Small frequent meals and dry starches help early nausea
  • Avoid unpasteurised dairy, raw or undercooked meat and eggs, and high-mercury fish
  • Increase fibre and fluid for constipation
  • Wash fruit and vegetables well, especially if home-grown

When to see us

  • You are planning a pregnancy — start folic acid before conception
  • You cannot keep fluids down, or are losing weight
