RT Journal Article SR Electronic T1 Diagnosis and Management of Breast Milk Oversupply JF The Journal of the American Board of Family Medicine JO J Am Board Fam Med FD American Board of Family Medicine SP 139 OP 142 DO 10.3122/jabfm.2016.01.150164 VO 29 IS 1 A1 Lauren Trimeloni A1 Jeanne Spencer YR 2016 UL http://www.jabfm.org/content/29/1/139.abstract AB Managing breastfeeding problems is an essential part of newborn care. While much is written on breast milk undersupply, little is written on oversupply, sometimes known as hyperlactation or hypergalactia. Infants of mothers with oversupply may have increased or decreased weight gain. Some may have large, frothy stools. They may develop a disordered latch. Mothers may report overly full, leaking breasts. Thyroid function should be assessed. Treatment is mostly anecdotal and includes methods to maintain breast fullness, such as block feedings. Pseudoephedrine and oral contraceptive pills may decrease the supply. Dopamine agonists such as carbergoline can be used as a last resort.
