I have been studying attachment theory and doing some research on how childhood attachment affects the health of people as they grow older. There is evidence that a poor childhood attachment leads to all kinds of problems and especially poor health. While I am not an expert on this subject, I have read some and can relate to it because I have had 3 autoimmune disease and I often wondered if they were somehow connected to being a parentified child.
Every adult I have talked to who admits to being parentified (or abused in some manner) as a child reports digestive and thyroid problems or autoimmune disease. At first, I thought this was very odd because I was sure I was the only one. But the more women I talked to who were parentified, the more I began to see the pattern. Parentification does lead to health problems, at least anecdotally and as reported by adults who were parentified children, and although my "research" on this is not scientific, it seems important to me. Parentification not only steals a childhood. It steals good health that we should be experiencing in adulthood.
