O99.0: Anaemia complicating pregnancy, childbirth and the puerperium

Blood is made up of a liquid part and different blood cells, among other things. The blood cells include the red blood cells, the white blood cells and the platelets. The red blood cells carry oxygen from the lungs throughout the body.

Red blood cells contain the red hemoglobin that gives blood its color. This pigment is important for carrying oxygen in the blood. Haemoglobin needs various nutrients to be formed. These nutrients include, for example, various proteins, vitamins and iron. You can have too little hemoglobin if, for example, you do not consume enough nutrients or after heavy bleeding.

The lack of hemoglobin makes your pregnancy, the birth or childbed more difficult. You may also already have had too little hemoglobin before your pregnancy. This lack of hemoglobin can then also have got worse as a result of your pregnancy, the birth or childbed.

If you don’t have enough haemoglobin, then the body can no longer transport as much oxygen. This can mean you’re exhausted more quickly or you have difficulty breathing.
