Breastfeeding During Menstruation: Does Breast Milk Decrease?
Menstruation is one of the topics that breastfeeding mothers are most curious about. There are many mothers who worry that their breast milk will decrease with menstruation or that the baby will not be fed enough. So, does menstruation really affect milk production?
The most important of these is the following question:
“I've got my period, will my milk supply decrease?”
The number of mothers who are worried about this issue is quite high. However, menstruation often does not mean that breastfeeding has ended or that the baby will be deprived of breast milk.
When Does a Breastfeeding Mother Menstruate?
During breastfeeding, prolactin hormone is found at high levels in the body. The hormone prolactin is responsible for breast milk production and can also suppress ovulation.
Especially in babies who are exclusively breastfed in the first months, menstruation may be delayed because the prolactin level remains high.
But over time;
- Baby's growth,
- Decrease in breastfeeding frequency,
- Starting supplementary food,
- Decrease in night sucking,
For reasons such as this, changes in prolactin levels occur and ovulation may begin again.
Therefore, it is completely normal for breastfeeding mothers to menstruate.
Does Menstruation Mean That Milk Has Stopped?
Absolutely not.
Menstruation does not mean that breast milk has completely stopped or breastfeeding has ended.
Because the prolactin hormone continues to work actively not only after birth but throughout the breastfeeding process.
As you breastfeed your baby:
- Prolactin hormone is secreted,
- Oxytocin hormone comes into play,
- Breast milk production and milk flow continue.
Therefore, menstruation is not an obstacle to breastfeeding.
Can Breast Milk Decrease During Menstruation?
Yes, some mothers may experience a temporary and slight decrease in milk production during their menstrual period.
This condition is caused by hormonal changes and is usually short-term.
Some mothers before or during their period:
- Decreased feeling of fullness in the breasts,
- The baby wants to breastfeed more often,
- Slight changes in the amount of milk,
can make a difference.
However, this situation is often temporary.
Does the Baby Go Hungry During Menstruation?
No.
Slight milk changes during menstruation are generally not at a level that will negatively affect the baby's nutrition.
As the baby continues to breastfeed, milk production continues.
When the temporary hormonal changes caused by menstruation end, milk production usually returns to its previous pattern.
Should Breastfeeding Be Continued During Menstruation?
Absolutely yes.
Menstruation is not a situation that requires a break from breastfeeding.
On the contrary, regular breastfeeding:
- Supports the continuation of milk production,
- Increases prolactin levels,
- It helps the breast milk production mechanism to remain active.
What Can Be Done to Support Milk During Menstruation?
In this period:
- Frequently breastfeeding the baby,
- Consuming enough fluids,
- Eating a balanced diet,
- Taking care to rest,
- Staying away from stress as much as possible,
may help support breast milk production.
Does the Taste of Breast Milk Change During Menstruation?
Some mothers may notice that the taste of breast milk changes during menstruation or that their babies suckle the breast more reluctantly. This is because hormonal changes can cause temporary differences in some mineral contents of breast milk, such as sodium and chloride.
However, these changes are usually mild and return to normal in a short time. Most babies continue to breastfeed without any problems.
Does the Quality of Breast Milk Deteriorate During Menstruation?
No.
Menstruation does not significantly change the nutritional value of breast milk.
Breast milk;
- protein,
- oil,
- carbohydrate,
- vitamin,
- mineral,
- antibody
continues to preserve its content.
Therefore, breastfeeding can be continued safely during menstrual periods.
In what cases should a doctor be consulted?
It is recommended that you consult an obstetrician or gynecologist or a healthcare professional experienced in breastfeeding if:
- A significant decrease in the amount of milk that lasts for a long time
- Baby not gaining enough weight
- Severe pain or redness in the breast
- Fever and mastitis symptoms
- Unbearable pain during breastfeeding
- Persistence of menstrual irregularity for a long time

Result
Although there may be temporary and slight changes in breast milk production during menstruation, this does not mean that breast milk has stopped or that the baby cannot be fed enough. As breastfeeding continues, prolactin and oxytocin hormones continue to work and milk production continues. When the menstrual period ends, milk production usually returns to its previous pattern.
