Understanding how your health may impact your milk

​

Your body is designed to produce milk, but certain medical conditions can influence how easily and how much milk is made. Your body is not failing you—sometimes it just needs the right support, at the right time. Many of these factors are connected to hormones, metabolism, nutrient status, or breast development, all of which play a role in milk production.

​

Some of the most common factors we see include:

• Thyroid disorders (hypo- or hyperthyroidism), PCOS, insulin resistance, diabetes, or a history of infertility

• Pregnancy-related conditions such as gestational hypertension, preeclampsia, or gestational diabetes

• Nutrient and blood-related concerns, including anemia, vitamin deficiencies (B12, vitamin D, iodine, iron), bariatric surgery, or conditions affecting absorption like celiac disease

• Breast and surgical history, including breast reduction, augmentation, lift, biopsy, insufficient glandular tissue (IGT), or fibrocystic breast changes

• Mental health factors such as mood disorders, chronic stress, anxiety or depression

 

Having one or more of these does not mean you can’t breastfeed. It simply means your body may need more individualized support and a thoughtful plan.

​

We take an individualized approach to lactation care, before and after delivery. Understanding your medical history during pregnancy allows us to identify potential challenges early and create a plan tailored to your body—so you’re not trying to figure things out after labor, exhaustion, pain, or unexpected complications.

 

If concerns arise postpartum, we move beyond guesswork with a comprehensive approach that may include:

​

• A full lactation assessment

• Detailed medical history review

• Targeted lab work, when clinically indicated, to assess for underlying causes

• A personalized plan to support your milk production

Your baby’s start can also influence how feeding begins.

 

Certain newborn or delivery-related factors may make early feeding more complex or delay the transition to full milk production.

 

These may include:

• Separation after birth, including NICU admission

• Prematurity or early term birth (before 38 weeks)

• Intrauterine growth restriction (IUGR) or low birth weight

• Larger birth size (LGA) or infants of diabetic mothers

• Meconium aspiration or need for respiratory support

• Phototherapy for jaundice

• Excessive early weight loss

• Missed or delayed feeding in the first hour after birth (“golden hour”)

 

These situations are common and often temporary, but they can impact early latch, feeding coordination, and the stimulation needed to establish milk supply. With the right support and a plan in place, many families go on to have successful breastfeeding experiences.
