Unexpected Milk Production: Galactorrhea After Miscarriage

Galactorrhea without pregnancy?

I am 40 years old and have a 10-year-old child who was born vaginally.
I had a miscarriage about 40 days into my pregnancy last August.
My menstrual cycle is usually very regular.
During ovulation, I experience breast tenderness.
Yesterday, for no particular reason, when I squeezed my breasts, I noticed that there was milk coming out.
I was able to express about 2ml of milk from both breasts, and the skin appearance on both sides is normal, with no indentation or lumps, just as it has always been.
Currently, I am in my ovulation period, and my last menstrual period was from June 29 to July 4.
Additionally, I have been feeling more fatigued lately and have had insufficient sleep.
I am unsure if this could have an impact.
I would appreciate your help in addressing my concerns.
Thank you.

The response suggests that there may be a hormonal imbalance in the body, specifically an excessive secretion of a hormone called prolactin.
It is advisable to visit a hospital for a blood test.

More Info

Galactorrhea, or the unexpected production of milk, can occur for various reasons, and it can be particularly concerning when it arises after a miscarriage. In your case, given your recent history of miscarriage and the fact that you are experiencing this milk production during your ovulation period, there are several factors to consider.

Firstly, hormonal fluctuations are a common cause of galactorrhea. After a miscarriage, your body undergoes significant hormonal changes as it attempts to return to its pre-pregnancy state. The hormone prolactin, which is responsible for milk production, can sometimes remain elevated for a period following pregnancy loss. Stress, fatigue, and lack of sleep, which you mentioned experiencing, can also contribute to hormonal imbalances, potentially leading to increased prolactin levels.

Additionally, certain medications, including those for mental health conditions or hormonal treatments, can cause galactorrhea as a side effect. If you are taking any medications, it would be wise to review these with your healthcare provider to rule out any potential links.

Another important consideration is the possibility of an underlying medical condition. Conditions such as hypothyroidism, pituitary tumors (prolactinomas), or other endocrine disorders can lead to abnormal milk production. If the galactorrhea persists or is accompanied by other symptoms, such as changes in your menstrual cycle, breast pain, or any unusual discharge, it is crucial to seek medical evaluation. A healthcare provider may recommend blood tests to check hormone levels, including prolactin, thyroid hormones, and others, to help determine the cause.

In your case, since you mentioned that the milk production is unilateral and that the breast tissue appears normal without any lumps or skin changes, this is a positive sign. However, it is still essential to monitor the situation closely. If you notice any changes, such as an increase in the volume of milk produced, changes in breast appearance, or any discomfort, it would be advisable to consult with a healthcare professional.

In summary, while galactorrhea can be a benign condition, especially in the context of recent hormonal changes following a miscarriage, it is essential to approach this symptom with caution. Factors such as stress, hormonal imbalances, and potential underlying medical conditions should be considered. If the symptom persists or worsens, a thorough evaluation by a healthcare provider is recommended to ensure that any underlying issues are addressed appropriately. Taking care of your overall health, including managing stress and ensuring adequate rest, can also help in regulating hormonal balance and improving your well-being.
