Because women are becoming pregnant at a later age, hypertension is more commonly encountered in pregnancy. In addition, with increasing numbers of young women living with renal transplants and kidney disease, it is important for physicians to be aware of the effects of pregnancy on these diseases. A multidisciplinary approach is essential to assess and care for pregnant women with kidney disease. Pre-pregnancy counselling should be offered to all women with chronic kidney disease. A review of medication to avoid teratogenicity and optimise the disease prior to conception is the ideal. Pregnancy may be the first medical review for a young woman, who may present with a previously undiagnosed renal problem.
