Can hormone imbalance cause low milk supply?

Understanding Hormone Imbalance and Low Milk Supply
Hormone imbalance can significantly impact a woman’s ability to produce breast milk, a concern that affects approximately 10% to 15% of mothers. The intricate relationship between hormones and lactation is crucial for understanding why some women experience low milk supply (LMS).
The Role of Key Hormones
Milk production is primarily regulated by two hormones: prolactin and oxytocin. Prolactin is responsible for milk synthesis, while oxytocin facilitates the milk ejection reflex. However, various hormonal conditions can disrupt this delicate balance. For instance, low thyroid hormone levels can interfere with both prolactin and oxytocin, leading to reduced milk production and impaired milk ejection. This is particularly concerning because standard laboratory ranges for thyroid function may not adequately reflect optimal levels for breastfeeding mothers.
Additionally, conditions such as polycystic ovarian syndrome (PCOS) and insulin dysregulation have been linked to chronic low milk supply. These conditions can alter hormonal levels in ways that negatively affect lactation.
Estrogens and Progesterone
Estrogens and progesterone also play significant roles in lactation. During pregnancy, these hormones prepare the breasts for milk production. However, after childbirth, their levels drop, allowing prolactin to take precedence. If there is an imbalance in these hormones, it can lead to insufficient milk supply.
External Factors and Hormonal Influence
Beyond intrinsic hormonal issues, external factors such as stress, inadequate breastfeeding techniques, and even certain medications can exacerbate hormonal imbalances, further complicating the situation. Stress, for example, can elevate cortisol levels, which may inhibit prolactin secretion and disrupt the breastfeeding process.
Conclusion
In summary, hormone imbalance is a significant factor that can lead to low milk supply in breastfeeding mothers. Understanding the roles of prolactin, oxytocin, thyroid hormones, and other related hormones is essential for addressing lactation challenges. For mothers experiencing low milk supply, consulting healthcare providers to evaluate hormonal levels and explore potential underlying conditions is crucial for finding effective solutions.

How to tell if breast milk is drying up?

The following are signs your baby isn’t getting enough milk:

1. Poor weight gain. It’s normal for newborns to lose 5% to 7% of their birth weight in the first few days – some lose up to 10%.
2. Insufficient, wet or dirty nappies.
3. Dehydration.

What deficiency causes low milk supply?

Deficiencies in certain key nutrients can also play a role in low milk supply. Many in the United States are low in iron, putting breastfeeding parents at risk for exhaustion and depression. Low iron levels are also a risk factor. Mothers may be low in other important nutrients as well: vitamins D and B12.

Can hormone imbalance affect milk supply?

A: There are a number of hormonal conditions that are known to be related to chronic low milk supply — among them are thyroid dysfunction, polycystic ovarian syndrome and insulin dysregulation/metabolic syndrome.

How long does it take for hormones to balance postpartum?

The return to pre-pregnancy hormone levels can vary greatly, but generally hormones will normalize within three to six months. If you are breastfeeding, as you wean from it, your prolactin and oxytocin levels will drop—potentially leaving you feeling sad, anxious or irritable.

Why is nothing increasing my milk supply?

The key to increasing your milk supply is frequent stimulation and emptying of the breasts. This may take some time and it is important that you seek advice and support from a lactation consultant, your maternal and child health nurse or other health care professional skilled in breastfeeding management.

Do soft breasts mean no milk?

Your breasts feel softer
This happens as your milk supply adjusts to your baby’s needs. The initial breast fullness reduces in the first few weeks. At around 6 weeks, breast fullness is completely gone and your breasts may feel soft. This is completely normal and has no effect on your milk supply.

What hormone causes lack of milk production?

In particular, chronic stress and severe anxiety can significantly contribute to dwindling breast milk supplies. The intricate relationship between stress and reduced lactation occurs because cortisol, the stress hormone, can interfere with the production of prolactin, a hormone vital for milk production.

What causes a drastic drop in milk supply?

A decrease in milk supply can be caused by a variety of different factors. A very common (and solvable) problem is not pumping or feeding enough. Because milk production works on a supply and demand basis, not pumping on a frequent schedule will signal to your body that it does not need to produce milk.

What negatively affects breast milk supply?

Supplementing with formula
However, supplementing with formula for multiple feedings every day (such as while the baby is at daycare) or releasing breast milk only when the baby wants to nurse tells your body that it doesn’t need to produce as much milk. Consequently, your supply will begin to decrease.

What are the symptoms of hormonal imbalance while breastfeeding?

Estrogen and Progesterone
For some individuals, this sudden drop in hormones can cause emotional symptoms like sadness, irritability, or stress. For many people, these emotional symptoms, which are frequently called the “baby blues,” only last a few weeks postpartum and resolve without any additional support.
