Chronic kidney weakness often leads to premature births, death of the child in the womb or a deficient birth. Complications for the mother may include bleeding, coagulation disorders, high blood pressure. However, the risk varies from one individual to another. Pregnant women with kidney disease must therefore be intensively cared for by experienced doctors.
If the creatinine level in the blood is significantly increased, a viable child is rarely born. With normal creatinine, pregnancy is all the more problematic the higher the protein level in the urine. In about 5-10% of first-time mothers, the urine protein is elevated towards the end of pregnancy. A combination of increased urine protein, increased blood pressure and water retention in the tissue (edema) is called gestosis.
Water retention can occur in any pregnancy. This explains much of the weight gain. After delivery, this fluid is excreted again and the mother loses the extra body weight. Sometimes, however, stronger oedemas accumulate. These are bothersome but not dangerous as long as there is no protein in the urine and the blood pressure remains normal. In this case, the doctor can treat the water retention with elevated leg positioning, less salt consumption and support stockings. Diuretic drugs, on the other hand, should not be given during pregnancy as they can slow down the blood flow to the placenta.
