Being pregnant inevitably means you will gain weight. However, how much weight you gain varies from woman to woman. Whilst it often becomes a source of concern for many pregnant women many caregivers have become less inclined to regularly weigh expectant mums as part of their routine care. Frequent weighing can often only create anxiety for women about 'not putting on enough' or 'putting on too much' weight.
It is fairly common for caregivers to ask you to weigh yourself as part of your first pregnancy visit. This is aimed at having a 'baseline' weight in case the doctor needs to prescribe drug dosages calculated on your average weight at some stage. However, beyond this weighing during pregnancy becomes a little irrelevant. Even so, some caregivers still continue to weigh women as part of their routine antenatal visits.
About weight gain
Whatever your weight was before your pregnancy, and regardless of how much weight you are (or are not) putting on, it is important to have a well-balanced diet with plenty of carbohydrates, protein and fresh fruits and vegetables, with not too many fatty and sugary foods. Pregnancy is not an appropriate time to diet, nor is it an excuse to 'eat for two'! If you have a special diet, or any health conditions that require diet modification (such as diabetes), you should consult with a dietician about planning your weekly meals.
Many information sources and pregnancy books will try to provide guides about the 'recommended weight gain' during pregnancy. These are usually along the lines of 'putting on 2- 3 kg in the first 20 weeks, then ½ a kilo per week until the baby is due, averaging 12-14 kg in total. While this may be true for some in women, in practise this is rarely the case.
