The article presents the provisions currently in force in Polish legislation regarding legal termination of pregnancy. In particular, it refers to the premise of a psychiatrist’s decision that the health of a pregnant woman is at risk. Under Polish law, termination of pregnancy is generally prohibited and penalized. However, there are two exceptions to this prohibition. Such a procedure is permitted if: the pregnancy poses a threat to the life or health of the pregnant woman, or if there is a reasonable suspicion that the pregnancy was the result of a prohibited act. The text presents an overview of the relevant regulations and tips on their interpretation and application in everyday medical practice. This issue is particularly important for psychiatrists consulting maternity wards. In addition, the most important mental disorders related to pregnancy and childbirth are described. The clinical features and prevalence of perinatal mood disorders and psychoses are presented. The issue of suicide among pregnant and postpartum patients was also discussed. A sample certificate template was proposed, and guidelines were discussed as to what information and conclusions should be included in the opinion of a psychiatrist.
