Hormonal causes of low milk supply are, in my mind, the final frontier of our understanding of milk supply problems. We know a lot about the normal course of lactation in women without hormonal or metabolic imbalances, and how to protect and rebuild milk supply when one of many Booby Traps drives things off course. But for those who do have hormonal imbalances and suffer milk supply problems, we know too little and have too few solutions to offer. So I was very interested to see a new study published this year by a Norwegian research team investigating the effect of metformin use in pregnancy on breastfeeding outcomes among women with Polycystic Ovary Syndrome (PCOS). PCOS, a hormonal imbalance affecting as many as 15% of all women, has for some time been implicated in milk supply problems. But it’s a slippery issue – some women with PCOS have dramatic milk supply problems, some don’t, and some even have an oversupply. The theory of its effect on lactation is that – in some cases – it may cause the underdevelopment of the breast during pregnancy (and possibly even in puberty), making less glandular tissue available for milk production and resulting in low milk supply. metformin work Many moms with PCOS have no problems with breastfeeding, but recent research is showing that mothers with PCOS are at greater risk for insufficient milk supply. On the other hand, about one-third of women with PCOS report problems with oversupply (perhaps this is connected with the hyperprolactinemia – elevated prolactin levels – that occurs in about 20% of moms with PCOS).

In every pregnancy, a woman starts out with a 3-5% chance of having a baby with a birth defect. This sheet talks about whether exposure to metformin may increase the risk for birth defects over that background risk. This information should not take the place of medical care and advice from your health care provider. Metformin is an oral medication used to treat type 2 diabetes (once known as adult-onset or noninsulin-dependent diabetes). It is also used to treat insulin resistance in polycystic ovarian syndrome (PCOS). Other names for this medication include Glucophage®, Diformin®, Glumetza®, FORTAMET If you become pregnant while using metformin, you should not stop your medication without first talking to your health care provider. High blood sugar levels before and during pregnancy increase the chance of birth defects and other complications. Insulin is usually the medication of choice in pregnancy because it can usually control blood sugar levels better than oral medications. Polycystic ovarian syndrome (PCOS) is a complex hormonal condition that affects 5% to 10% of women of reproductive age. Features of PCOS can include fertility problems, acne, obesity, excess body hair growth and an increased risk of developing type 2 diabetes. PCOS and milk supply Little research has been done on PCOS in relation to breastfeeding. A possible connection between PCOS and a low milk supply was initially presented in a case study in 2000 of 3 mothers with PCOS who also had low milk supply. of 36 mothers with PCOS and 99 mothers without PCOS concluded that mothers with PCOS appear to have a reduced breastfeeding rate in the early postnatal period as compared to mothers without PCOS. By 3 months however, breastfeeding rates were equal between mothers with and without PCOS. The researchers in this study also found a possible negative link between ‘pre-androgen’ hormone levels in PCOS mothers and breastfeeding rates.
