Staying healthy during your pregnancy

​​​​Food, drink and vitamin supplements

You should try to drink approximately three to four pints of liquid a day.


Drinking alcohol while you're pregnant can seriously harm your baby's development. 

There's no way of knowing what level of drinking could be harmful to your baby, but to be on the safe side, it's best to avoid alcohol altogether during pregnancy.​


Coffee contains caffeine which can act as a stimulant to your urinary tract and is therefore best avoided. 

You should not have more than 300mg of caffeine a day, the equivalent of:

  • 3 mugs of coffee
  • 6 mugs of tea
  • 8 cans of coke
  • 8 bars of chocolate


You should only drink pasteurised or UHT milk.

Foods to avoid

Foods to try to avoid are:

  • pâtés of all sorts
  • liver or liver products
  • raw or partially cooked eggs
  • uncooked or cured meats eg salami
  • unpasteurised soft cheeses
  • raw shellfish eg oysters
  • shark
  • marlin
  • swordfish

Don't have more than two portions of oily fish a week. 

Vitamin supplements

You should take a 400 microgram tablet of folic acid every day until you are at least 12 weeks pregnant. 

Vitamin supplements can be used but you should always consult your pharmacist first as some vitamins, eg vitamin a, can be harmful to your baby.

Smoking and medication

Smoking in pregnancy increases the risk of cot death, miscarriage, stillbirth and premature babies. 

When it comes to pills and medication, you should assume all are dangerous to your baby until a doctor or pharmacist tells you they are safe. 

​Weight gain

Most women gain between 22 to 28lbs during pregnancy. 

Weight gain varies a great deal and depends on your weight before pregnancy. 

If you gain too much weight, this can affect your health and increase your blood pressure.


There is no need to stop exercise when you become pregnant, although extreme and high impact sports will need to be modified. 

Your GP or midwife can give you advice.

Exercise and pregnancy on NHS Choices website


In a normal pregnancy, if you feel like having sex, you will not cause any harm to the baby. 

Some women experience a reduced sex drive during pregnancy, which is normal and you should not be concerned. You should talk to your partner about how you feel.  

In certain circumstances, eg if your placenta is low sited or you have a history of miscarriage, you may be advised to avoid intercourse. Your doctor or midwife will advise you.​
