Does metformin affect milk supply?

Does Metformin Affect Milk Supply?
Metformin, a medication primarily used to manage type 2 diabetes, has garnered attention for its potential effects on lactation, particularly among mothers experiencing low milk supply. The relationship between metformin and milk production is complex and still under investigation, but emerging research provides some insights.
Understanding Metformin’s Role
Metformin works by improving insulin sensitivity, which can be beneficial for women who have insulin resistance—a condition that may contribute to low milk supply. Some studies suggest that metabolic factors, including insulin resistance, can negatively impact lactation. This has led to the hypothesis that metformin might help enhance milk production in certain populations of breastfeeding mothers.
Research Findings
A pilot randomized controlled trial aimed to explore the feasibility of using metformin to augment low milk supply. While the study’s primary focus was on the practicality of conducting a larger trial, it highlighted the potential for metformin to play a role in addressing low milk production linked to metabolic issues. However, definitive conclusions about its effectiveness in increasing milk supply remain elusive.
Metformin and Breast Milk
When it comes to breastfeeding, metformin does pass into breast milk, but the levels are relatively low. Research indicates that infants would receive less than 0.5% of their mother’s weight-adjusted dosage of metformin through breast milk. This low transfer rate suggests that while metformin is present in breast milk, it is unlikely to pose significant risks to breastfeeding infants.
Clinical Perspectives
Some healthcare providers have begun to consider metformin as a potential galactogogue—an agent that promotes lactation—especially for mothers with underlying insulin resistance or metabolic syndrome. However, it is crucial to note that there is currently no strong evidence supporting the effectiveness of metformin specifically for increasing milk supply. The existing studies primarily focus on its safety and the pharmacokinetics of the drug in lactating women.
Conclusion
In summary, while metformin may have a role in managing metabolic issues that could indirectly affect milk supply, its direct impact on lactation is still not well-established. Mothers considering metformin for low milk supply should consult with healthcare professionals to weigh the potential benefits and risks, especially given the complexities of individual health conditions and breastfeeding needs. As research continues, clearer guidelines may emerge regarding the use of metformin in breastfeeding mothers.

So please call us if you are breastfeeding and need clarification on the safety of a medication or to see if a medication you are taking may be affecting your milk supply while breastfeeding.

Why does diabetes cause low milk supply?

When our blood sugar levels are irregular, it stresses the body and can affect your hormonal balance. Hormones are crucial in milk production, and sometimes eating the right foods more often can make a big difference.

• some nasal decongestants that come as nose sprays or drops – check with a GP or pharmacist before using them.
• aspirin for pain relief.

How does metformin affect the baby?

Previous studies suggest fetal exposure to metformin may increase the risk of lower birth weight and adverse metabolic outcomes in offspring, as well as a higher risk of increased body weight, obesity and metabolic dysfunction in preadolescence.

How does metformin affect breast milk?

Metformin passes into breast milk in tiny amounts and has not been linked with side effects in any breastfed babies. Metformin would not be expected to cause side effects but contact your health visitor, midwife, pharmacist or doctor as soon as possible if your baby: is not feeding as well as usual.

What does a PCOS belly look like?

This may be due to bloating, excessive weight gain, or both. Women with PCOS will often find it difficult to lose belly fat.

What does metformin do for PCOS?

Many studies showed that metformin, when used to treat PCOS, significantly reduced serum androgen levels, improved insulin sensitivity, restored menstrual cyclicity, and was successful in triggering ovulation. As a result, metformin may be useful in treating PCOS-related infertility.
