Fabricated or induced illness. Fabricated or induced illness (FII) is a rare form of child abuse. It occurs when a parent or carer, usually the child's biological mother, exaggerates or deliberately causes symptoms of illness in the child. FII is also known as 'Munchausen's syndrome by proxy' (not to be confused with Munchausen's syndrome, where a person pretends to be ill or causes illness or injury to themselves).
In rare cases, a woman (or even a man) believes she is pregnant, only to find out that her symptoms were caused not by pregnancy, but by something else entirely. False pregnancy, clinically termed pseudocyesis, is the belief that you are expecting a baby when you are not really carrying a child. People with pseudocyesis have many, if not all, symptoms of pregnancy -- with the exception of an actual fetus.
