O21: Excessive vomiting in pregnancy

O21.2: Late vomiting of pregnancy

Early on in their pregnancy, in particular, many pregnant women feel nauseous or occasionally need to vomit. But some may feel the need to vomit more frequently than normal. This can result in everyday limitations. However, in your case the frequent vomiting only began after the 20th week of your pregnancy.

This frequent vomiting may result in additional problems. For example, you might lose weight or have too little fluid in your body. You may also be taking in too few nutrients and your body’s metabolism may be disturbed.
