This article reviews different aspects of maternal weight before and during pregnancy and @entity1017 in pregnancy, e.g. causes of undernourishment ( @entity7494 , @entity1278 ). Physiological @entity1017 during pregnancy is normally between 10 and 16 kg, representing 20% of the body weight before pregnancy. The increase in weight is usually lowest during the 1st trimester and greatest between the 17th and the 24th week of pregnancy. Low maternal weight at conception may cause low birthweight. Undernourishment may cause @entity3465 or low birthweight, or both. There is an increased risk of gestational @entity6 and @entity8455 , as well as @entity3152 and @entity101 in pregnant @entity1 who are overweight. There is also an increased risk of complications arising during general anaesthesia and operative delivery in severely overweight @entity1 . These @entity1 should be offered heparin or dextran as @entity715 prophylaxis where a caesarean section is to be performed. They should also be given antibiotic prophylaxis. A @entity1017 of between 7 and 12 kg reduces the risk of complications in overweight @entity1 .
