Weight gain in pregnancy

Yes, you are eating for two, but unfortunately this does not mean eating twice as much as usual. So how much should you consume when you are pregnant and how much weight can you expect to gain?

How much weight will I gain?
Every woman is different. Some women can feel like they are putting on pounds from day one, but if you suffer from morning sickness you may actually lose weight to start with through nausea and vomiting. Unless you become dehydrated this is nothing to worry about, but speak to your midwife if you are at all concerned. As a general rule of thumb you can expect to gain anywhere between 1.5 to 3kg, about 3 to 6lb, in the first trimester and around 0.5kg, or 1lb, a week from then on.

Over the whole pregnancy, an average-sized woman will gain around 10 to 12kg or 22 to 28lb. But this figure will depend on how heavy you were at the start of your pregnancy and if you are expecting more than one baby. Talk to your midwife, who will be able to advise you on what is healthy for your circumstances.

Do I need to eat more than usual?
It is only during the third trimester, when your baby's weight will triple, that you need to increase the amount you consume. But even then the Department of Health recommends just 200 calories a day more than usual. This is roughly equivalent to two pieces of bread.

Pregnancy need not mean denying yourself the occasional treat though. The odd scoop of ice cream or chocolate bar is fine occasionally.

Is dieting OK in pregnancy?
Too much weight can affect your health and increase your blood pressure, but dieting is not recommended either. It can leave you low in iron and folic acid, harming both you and your unborn baby. The key to managing your weight is to make every calorie count, so limit high fat or sugar-laden food and snacks. They are full of empty calories, which means they come with few or no nutrients. If you are worried about any aspect of your weight gain speak to your midwife or GP.
