Low Prolactin Levels and Vaginal Scar Tissue After Breastfeeding

Prolactin

Hello doctor, I would like to ask about a situation.
It has been 8 months since I stopped breastfeeding, but I can still express a small amount of yellowish milk from my left breast.
A visit to a breast surgeon showed no issues with cysts or tumors, so I had my prolactin levels tested, which came back at 3.88.
Could you please explain what problems might arise from low prolactin levels? Additionally, I have noticed a white, hard, round spot in the middle of my vagina that feels like a pimple.
I also went for a gynecological examination, and the doctor mentioned it might be a scar from the stitches after a natural delivery.
Can a vaginal scar appear as a white round spot like a pimple? I would appreciate your answers to these two questions.
Thank you.

The white spots need to be examined to determine the issue.
If there are any concerns, please consult a specialist for further evaluation.

Understanding low prolactin levels and vaginal scar tissue after breastfeeding involves addressing two distinct but interconnected issues: hormonal balance and physical changes post-delivery.

Firstly, regarding your low prolactin levels, a reading of 3.88 ng/mL is considered low, especially in the context of breastfeeding cessation. Prolactin is a hormone produced by the pituitary gland that plays a crucial role in milk production. After breastfeeding, prolactin levels typically decrease, but they should not drop to extremely low levels unless there is an underlying issue. Low prolactin can lead to several concerns, including:
1. Inadequate Milk Production: While you have already stopped breastfeeding, low prolactin levels can affect future lactation if you decide to breastfeed again.

2. Menstrual Irregularities: Prolactin is involved in regulating the menstrual cycle. Low levels may lead to irregular periods or amenorrhea (absence of menstruation).

3. Bone Health: Prolactin influences estrogen levels, which are vital for bone density. Low prolactin may contribute to decreased estrogen levels, potentially increasing the risk of osteoporosis over time.

4. Mood Changes: Hormonal imbalances can also affect mood and emotional well-being, leading to symptoms of anxiety or depression.

If you are experiencing symptoms related to low prolactin, it is advisable to consult with an endocrinologist or your primary care physician. They may recommend further testing to explore the underlying causes of your low prolactin levels, which could include pituitary gland function tests or imaging studies.

Now, addressing the second part of your question regarding the white, hard, round spot in your vaginal area, it is not uncommon for women to experience changes in their vaginal anatomy after childbirth. The presence of scar tissue from perineal stitches or vaginal tears can lead to various physical manifestations, including:
1. Scar Tissue Formation: After natural childbirth, especially if there were any lacerations that required stitching, scar tissue can form. This tissue may feel different from the surrounding areas and can sometimes present as small bumps or hard spots.

2. Hygroma or Cyst: While your doctor suggested it might be scar tissue, it is also possible for benign cysts or other growths to develop in the vaginal area. These can sometimes feel like small, hard bumps.

3. Infection or Other Conditions: If the area is painful, swollen, or shows signs of infection (such as redness or discharge), it is essential to seek medical advice.
4. Normal Variation: Some women may have natural variations in their anatomy that become more noticeable after childbirth.

It is crucial to maintain open communication with your healthcare provider regarding any changes you notice in your body, especially after significant events like childbirth. If the spot is concerning or if you experience discomfort, further evaluation may be warranted.
In summary, both low prolactin levels and vaginal scar tissue can have implications for your health and well-being. It is essential to monitor your symptoms and consult with healthcare professionals who can provide personalized advice and treatment options based on your specific situation. Regular follow-ups can help ensure that any hormonal imbalances or physical changes are appropriately managed.
