O12: Gestational [pregnancy-induced] oedema and proteinuria without hypertension

O12.2: Gestational oedema with proteinuria

The body changes in pregnancy. Among other things, the body excretes fewer minerals and less fluid in pregnancy. As a result, an increased amount of fluid may build up in the tissue. This can cause the legs, hands or face, for example, to swell up.

The kidneys filter blood and create urine. Normally very little protein gets into the urine via the kidneys. During pregnancy, the kidneys work harder and are also slightly more permeable to proteins. This means that more protein is passed from the blood into the urine. However, in your case, you have too much protein in your urine. If too much protein is excreted, more fluid can get stored in the tissue.
