Pseudo-cyesis, also known as false pregnancy, is a psychological condition in which a woman believes she is pregnant but is not actually carrying a baby. There are many synonyms for pseudo-cyesis, including pseudopregnancy, phantom pregnancy, hysterical pregnancy, and spurious pregnancy. These terms all refer to the same condition and can be used interchangeably. False pregnancy can be caused by a variety of factors, such as anxiety, stress, and hormonal imbalances. Although it is a rare condition, it can have a significant impact on a woman's life. Treatment often involves psychological therapy and support from healthcare professionals.
