Why does my breastmilk smell eggy?

Understanding the Eggy Smell in Breast Milk
Experiencing an eggy smell in breast milk can be concerning for nursing mothers. This phenomenon is often linked to the presence of lipase, an enzyme naturally found in human milk. Lipase plays a crucial role in breaking down fats, making them easier for infants to digest. However, when breast milk is stored, particularly if it has been refrigerated or frozen, lipase can sometimes cause the milk to develop an unusual odor, including an eggy scent.
The Role of Lipase
Lipase activity can lead to oxidation of the milk fats, which may result in a smell that some mothers describe as soapy or even eggy. This change does not indicate that the milk is spoiled or unsafe for the baby; rather, it is a normal reaction that occurs in some women’s milk due to the enzyme’s action. While most mothers report that their milk smells sweet or neutral, variations can occur based on individual body chemistry and the specific composition of their milk.
Factors Influencing Milk Odor
Several factors can influence the smell of breast milk, including:
– Diet: What a mother eats can significantly affect the taste and smell of her milk. Foods like garlic, spices, and certain vegetables can impart distinct odors.
– Storage Conditions: The way milk is stored can also impact its smell. If milk is not stored properly, it may develop off odors.
– Milk Composition: Each mother’s milk is unique, and the balance of fats and proteins can vary, leading to different smells over time.
When to Be Concerned
While an eggy smell is typically harmless, mothers should be vigilant for signs that their milk may be spoiled. If the milk has a distinctly sour or rancid odor, it may indicate that it has soured and should not be given to the baby. In contrast, if the milk smells off but does not have a sour note, it is likely still safe for consumption.
Conclusion
In summary, an eggy smell in breast milk is often a result of lipase activity and is generally not a cause for alarm. Understanding the factors that influence breast milk’s odor can help mothers navigate their breastfeeding journey with confidence. If concerns persist, consulting with a healthcare provider or a lactation consultant can provide additional reassurance and guidance.

How to reduce lipase in breastmilk?

Scalding milk is believed to slow lipase’s action in the milk. Research shows that lipase is not responsible for the changes in smell. Removing lipase removes an important enzyme that helps the baby digest fats.

How to tell if breast milk has high lipase?

The longer milk is kept at room temperature or even in the refrigerator before being frozen, the more lipase activity it will have. Milk that has a high level of lipase can develop a soapy smell and taste, but is not harmful to the baby.

What happens if a baby drinks bad breast milk?

How do I lower lipase in my breast milk?

Scald your pumped milk.
