Introduction

If you are navigating the journey of breastfeeding while living with Polycystic Ovary Syndrome (PCOS), you may feel like you are facing an uphill battle. It can be incredibly frustrating when the process that is supposed to be "natural" feels like a constant struggle. You might find yourself searching for answers, wondering why your supply isn't meeting your expectations or why your body seems to be working against you. Please know that you are not alone, and your feelings are completely valid.

At Milky Mama, we understand that breastfeeding challenges are often rooted in complex hormonal patterns rather than a lack of effort. Our founder, Krystal Duhaney, RN, BSN, IBCLC, created this community to ensure every parent has access to professional, compassionate lactation support. If you want personalized guidance, our Certified Lactation Consultant Breastfeeding Help page is a helpful place to start. This article will explore the specific ways PCOS impacts lactation and provide evidence-based strategies to help you boost your supply. By understanding the connection between your hormones and your milk production, you can take actionable steps to reach your feeding goals.

Understanding the PCOS and Lactation Connection

Polycystic Ovary Syndrome is more than just a reproductive issue. It is a complex endocrine disorder that affects how your body processes hormones and insulin. These same hormones play a vital role in how your breasts develop and how they produce milk. For many people with PCOS, the challenges with milk supply often stem from three main areas: breast tissue development, insulin resistance, and hormonal imbalances.

Breast Tissue Development

During puberty and pregnancy, the body relies on a delicate balance of estrogen and progesterone to grow milk-making tissue, also known as glandular tissue. Some people with PCOS may have "Insufficient Glandular Tissue" (IGT). This means the breasts may not have developed enough of the specialized cells needed to produce a full milk supply. While this can be a hurdle, it does not always mean you cannot breastfeed. Many parents with lower amounts of glandular tissue still find success through a combination of strategies.

The Role of Insulin Resistance

Insulin is a hormone that helps your body turn sugar into energy. Many individuals with PCOS experience insulin resistance, where the body's cells do not respond effectively to insulin. Fun fact: the breasts are actually a target organ for insulin. This hormone is necessary for "lactogenesis," which is the fancy word for the beginning of milk production. If your body cannot use insulin properly, it may struggle to "turn on" the milk-making process or maintain a consistent supply.

Hormonal Dominance

PCOS is often characterized by higher levels of androgens (male-pattern hormones) and sometimes an imbalance in estrogen and progesterone. High levels of testosterone can potentially interfere with prolactin, the hormone responsible for telling your body to make milk. Additionally, if progesterone levels do not drop appropriately after birth, it can delay the arrival of your mature milk.

Key Takeaway: PCOS affects milk supply through physical tissue development and metabolic hurdles like insulin resistance. Identifying these factors early allows you to customize your breastfeeding plan.

Stabilizing Blood Sugar to Support Supply

Because insulin plays such a critical role in milk synthesis, managing your blood sugar is one of the most effective ways to support your supply when you have PCOS. When your blood sugar is stable, your body is under less metabolic stress, which allows your hormones to function more effectively.

Focus on High Protein and Fiber

A diet rich in protein and fiber can help prevent the "spikes and crashes" in blood sugar that often plague those with PCOS. Aim to include a protein source with every meal and snack. This helps slow down the absorption of sugar into your bloodstream.

Protein sources: Boiled eggs, Greek yogurt, nuts, seeds, lean meats, and legumes.
Fiber sources: Berries, avocados, leafy greens, and whole grains like oats.

Choosing Low Glycemic Index (GI) Foods

The Glycemic Index measures how quickly a food raises your blood sugar. Choosing low-GI foods can improve your insulin sensitivity over time. Instead of white bread or sugary cereals, look for complex carbohydrates like brown rice, quinoa, and chickpeas. These foods provide a steady stream of energy, which is essential for an exhausted new parent.

Hydration and Lactation Drinks

Staying hydrated is essential for all breastfeeding parents, but for those with PCOS, choosing the right drinks matters. Many "sports drinks" are loaded with simple sugars that can trigger insulin spikes. We recommend looking for options that prioritize hydration without the sugar overload. Our Pumpin' Punch™ drink mix is a great way to stay hydrated while incorporating lactation-supporting ingredients.

What to do next:

Swap sugary snacks for a handful of almonds or a hard-boiled egg.
Incorporate one serving of complex carbohydrates into your lunch.
Track your water intake to ensure you are drinking enough to support your metabolic needs.

Targeted Galactagogues for PCOS

A galactagogue is a substance—usually a herb or food—that may help increase milk production. However, not all galactagogues are created equal, especially for someone with PCOS. Some herbs that work for the general population might not be the best fit for you. It is important to choose ingredients that also support blood sugar regulation.

Moringa (Malunggay)

Moringa is often called a "superfood" for a reason. It is packed with vitamins and minerals and has been used for generations to support milk supply. For moms with PCOS, moringa is particularly beneficial because it may help improve insulin sensitivity while naturally boosting prolactin levels. Many of our Milky Mama supplements, like Lady Leche™, utilize moringa as a primary ingredient for this very reason.

Goat's Rue

Goat’s rue is one of the most highly recommended herbs for those with PCOS or IGT. It is actually chemically related to metformin, a common medication used to treat insulin resistance. Goat's rue may help stimulate the growth of breast tissue and improve the way your body utilizes insulin. This makes it a powerful tool for those who suspect their supply issues are related to tissue development.

Milk Thistle and Nettle

Both of these herbs are known for their ability to support the liver and provide essential nutrients. Nettle is high in iron and chlorophyll, which can help with the fatigue that often accompanies PCOS. Milk thistle may help support the hormonal balance needed for a healthy let-down reflex (the process of milk moving from the back of the breast to the nipple).

Clinical Interventions and Supplements

When lifestyle changes and herbs aren't enough, you may want to speak with your healthcare provider about clinical options. Because PCOS is a medical condition, treating the underlying hormonal issues can often result in an improved milk supply.

Considering Metformin

Metformin is a medication commonly prescribed to help manage insulin resistance. Some studies and many anecdotal reports suggest that continuing metformin during the postpartum period may help breastfeeding parents with PCOS maintain a higher milk supply. It works by making your cells more sensitive to insulin, which allows the milk-making cells in your breasts to do their job more effectively.

Myo-Inositol

Myo-inositol is a naturally occurring substance that is often used as a supplement to help balance hormones in people with PCOS. It may help reduce androgen levels and improve insulin function. While more research is specifically needed on its impact on lactation, many lactation consultants recommend it as a safe and effective way to support metabolic health while breastfeeding.

Managing Testosterone

If your androgen levels remain high after birth, they can suppress your milk supply. In some cases, working with an endocrinologist to safely balance these hormones can make a significant difference. Some parents have found that herbs like Saw Palmetto may help, but these should always be discussed with a professional first.

Key Takeaway: Medical management of PCOS symptoms is often the "missing piece" in increasing milk supply. Always partner with a provider who understands both PCOS and lactation.

Maximizing Milk Removal and Stimulation

While hormones are the foundation, "supply and demand" is the engine that keeps milk production moving. The more milk you remove from your breasts, the more milk your body will try to create. For those with PCOS, extra stimulation is often necessary to overcome hormonal hurdles.

Frequent Feeding and Pumping

Aim to remove milk at least 8 to 12 times in a 24-hour period. If your baby is not latching well or is not transferring milk efficiently, you may need to use a high-quality breast pump to ensure your breasts are being emptied. If you are exclusively pumping, the How to Up My Milk Supply Exclusively Pumping guide may be especially useful.

The Power of Skin-to-Skin

Spending time skin-to-skin with your baby releases oxytocin, which is often called the "love hormone." Oxytocin is responsible for the let-down reflex. For parents with PCOS who may be dealing with higher stress levels or hormonal interference, frequent skin-to-skin contact can help "reset" the system and encourage milk flow.

Breast Massage and Compression

Using your hands to gently massage your breasts while nursing or pumping can help move more milk out. Think of it like squeezing a sponge—the more "dry" you can get the sponge, the more it will soak up when you put it back in water. This extra removal tells your body that the current supply isn't enough and it needs to ramp up production.

Tips for Effective Milk Removal:

Practice "hands-on pumping" by massaging your breasts while the pump is running.
Try a "babymoon" where you spend 24 to 48 hours mostly in bed with your baby, focusing only on skin-to-skin and nursing.
Ensure your pump flanges are the correct size; an improper fit can leave milk behind and signal your body to slow down production.

Supporting Glandular Tissue Growth

If you have Insufficient Glandular Tissue (IGT), your approach might look a little different. While you may not be able to grow new tissue overnight, you can maximize the function of the tissue you do have.

Antenatal Expression

If you are currently pregnant and know you have PCOS, you might talk to your provider about antenatal expression. This involves gently hand-expressing colostrum (your first milk) starting around 37 or 38 weeks of pregnancy. This early stimulation can "wake up" the breast tissue and may help your mature milk come in more quickly after birth.

Focus on Every Drop

When you have PCOS, it is easy to get discouraged by small pump volumes. However, we always say that "every drop counts." Even if you are not producing 100% of your baby's needs, the milk you are producing is full of antibodies, hormones, and nutrients that are specifically designed for your baby. If you want a deeper dive into supply concerns, the Understanding and Managing Low Milk Supply article is a great next step.

Pumping for Comfort and Supply

If you find that your supply is lower in the evenings, consider a "power pumping" session. This involves pumping for 20 minutes, resting for 10, pumping for 10, resting for 10, and pumping for 10. This mimics the "cluster feeding" a baby does during a growth spurt and can signal your body to increase its output over several days. Our Pumping Queen™ supplement is a popular choice for those looking to support their output during these intensive pumping periods.

Lifestyle Shifts for Lactation Success

Your physical health is deeply connected to your emotional well-being. Living with PCOS and a newborn can be incredibly taxing, so prioritizing self-care is not a luxury—it is a necessity for your milk supply.

Stress Management

High levels of cortisol (the stress hormone) can actively inhibit the let-down reflex. While it is impossible to eliminate stress as a new parent, finding small ways to manage it can help. This might look like five minutes of deep breathing, a warm shower, or asking a partner to handle the household chores so you can focus on your baby.

Gentle Movement

While intense exercise can sometimes be a stressor, gentle movement like walking or restorative yoga can improve insulin sensitivity. Improved insulin function leads to a better environment for milk production. Listen to your body and don't push yourself too hard, especially in the early weeks of recovery.

Nourishing Treats

Sometimes, you just need a snack that makes you feel good and supports your goals. Our Emergency Lactation Brownies are a fan favorite for a reason. They are packed with oats and flaxseed, which provide healthy fats and fiber to keep you satisfied and support your supply. Plus, they are a delicious way to reward yourself for all the hard work you are doing.

What to do next:

Identify one person in your support system you can ask for help with a non-feeding task today.
Dedicate 10 minutes to a relaxing activity that has nothing to do with baby care.
Keep a stash of high-protein, lactation-supporting snacks nearby your nursing station.

When to Seek Professional Support

PCOS presents unique challenges that are best managed with a team. You don't have to figure this out on your own. If you are struggling with low supply, pain, or frustration, reaching out for professional help is a sign of strength.

Work with an IBCLC

An International Board Certified Lactation Consultant (IBCLC) is the gold standard in breastfeeding support. They can help you assess your baby's latch, check for signs of IGT, and help you create a customized plan that accounts for your PCOS symptoms. If you want structured education alongside live support, the Breastfeeding 101 course is a natural next step.

Consult Your Endocrinologist

Since PCOS is a hormonal disorder, your endocrinologist or OBGYN can play a huge role in your breastfeeding success. They can monitor your blood sugar and hormone levels to ensure your body is in the best possible state to produce milk.

Mental Health Support

The link between PCOS and mood disorders like postpartum depression or anxiety is well-documented. If you find yourself feeling overwhelmed or hopeless, please speak with a mental health professional. Your well-being matters just as much as your milk supply.

Key Takeaway: A collaborative approach involving a lactation expert and your medical provider offers the best chance for navigating PCOS-related supply issues.

FAQ

Can I produce a full milk supply if I have PCOS?

Many people with PCOS are able to produce a full supply, especially with early intervention and proper hormonal management. However, some may experience a partial supply due to insufficient glandular tissue or insulin resistance. In these cases, many parents find a "combo-feeding" routine that includes both breastfeeding and supplementation to be a sustainable and happy balance.

Does Metformin help increase milk supply for moms with PCOS?

Metformin may help increase milk supply by improving insulin sensitivity, which is crucial for the milk-making cells in the breasts to function. While some studies show mixed results, many parents and lactation consultants report a noticeable improvement in supply when insulin resistance is medically managed. Always discuss the risks and benefits of any medication with your healthcare provider.

Why does PCOS cause low milk supply?

PCOS can cause low supply due to hormonal imbalances, such as high testosterone or low progesterone, which interfere with milk-making hormones like prolactin. Additionally, insulin resistance can hinder the metabolic processes needed for milk synthesis, and some individuals may have less milk-making (glandular) tissue. Understanding these underlying causes is the first step in finding the right solutions.
