From the abstract: " Phenylketonuria (PKU) is a metabolic condition that requires treatment for life. There is increasing evidence that chronic illnesses put strain on relationships and marriages. However, no studies have examined the unique factors that metabolic conditions have on affected individuals and their relationship satisfaction. We surveyed a population of adult patients with PKU and assessed how management, treatment, and lifestyle factors impact their relationship satisfaction." https://phgkb.cdc.gov/PHGKB/phgHome.action?query=Phenylketonuria&action=search&Mysubmit=Search
