Search for: [Abstract = "Introduction\: Gestational diabetes mellitus \(GDM\) is a time\-limited disease that occurs during pregnancy. Unfortunately, the risk of shortand long\-term complications for both mother and child is high. Among the frequently reported in the literature health consequences of infant mothers with GDM are for example early childhood overweight, obesity and even early\-onset diabetes. The mechanism of metabolic changes during infancy and early childhood is not fully understood yet. Many scientific studies report that breastfeeding has a protective effect for both mothers with a history of GDM and their babies. However, there are studies that indicate a potential link between milk from diabetes mothers and increased body fat in infancy. The effect of GDM on the composition of the breast milk has not been thoroughly reported in the literature. The hypothesis for this study was that gestational diabetes mellitus significantly affects the mean total and true protein, carbohydrate, fat, and energy value of milk at 3rd, 7th, 14th, 21 st and 28th day of lactation. Methodology\: A total number of 145 mother\-infant dyads, \(74 women with GDM and 71 healthy women\), participated in this study. Participants were included in the study group after the delivery in the maternity and neonatal units at Department of Gynecology and Perinatology, Jagiellonian University and Gynaecological and Obstetrics H"]
