Introduction
In general, continued milk production two months after weaning may be caused by slow decline of prolactin levels, frequent breast stimulation, hyperprolactinemia, mammary gland hyperplasia, or pituitary microadenoma. If milk secretion persists or is accompanied by other discomforts, it is recommended to seek timely medical evaluation at a reputable hospital. In daily life, avoid breast stimulation and wear comfortable undergarments; maintain regular sleep patterns and reduce mental stress.

Under normal circumstances, continued milk production two months after weaning may be caused by slow decline of prolactin, frequent breast stimulation, hyperprolactinemia, mammary gland hyperplasia, pituitary microadenoma, or other reasons. If milk secretion persists or is accompanied by other discomforts, it is recommended to seek timely medical evaluation at a正规 hospital. Detailed analysis is as follows:

1. Slow Decline of Prolactin

After weaning, prolactin levels in the body need to gradually decrease. In some individuals with slower metabolism, the hormone remains elevated and continues to stimulate the mammary glands before returning to normal levels. Reducing fluid intake, avoiding breast compression, and allowing time for natural hormonal recovery usually lead to resolution within several months.

2. Frequent Breast Stimulation

Repeated massage, friction from clothing, or other stimuli can send lactation signals to the brain, prompting continuous milk production. Wearing loose-fitting cotton underwear and avoiding intentional touching or squeezing of the breasts helps reduce external stimulation.

3. Hyperprolactinemia

This condition involves abnormally elevated prolactin levels due to endocrine disorders, leading to persistent milk secretion, often accompanied by menstrual irregularities. Under medical guidance, medications such as bromocriptine mesylate tablets, vitamin B6 tablets, or cabergoline tablets may be prescribed. Maintaining regular sleep patterns and avoiding late nights are also important.

4. Mammary Gland Hyperplasia

Excessive proliferation of breast tissue affects glandular function and interferes with the normal cessation of milk production, possibly accompanied by breast tenderness. Under medical supervision, treatments such as Ruxiaoxiao tablets, Xiaoyao pills, or Xiaojin pills may be used. Emotional stability should be maintained, and spicy foods avoided.

5. Pituitary Microadenoma

A pituitary tumor that secretes excessive prolactin can cause persistent milk discharge, sometimes accompanied by headaches or blurred vision. Medications such as bromocriptine mesylate tablets, quinagolide tablets, or pergolide tablets may be prescribed under medical guidance. In severe cases, transsphenoidal resection of the pituitary microadenoma may be required.

In daily life, avoid breast stimulation and choose comfortable undergarments; maintain regular作息, reduce mental stress; follow a balanced diet and limit high-fat, high-sugar foods. Seek prompt medical evaluation if milk secretion persists or is associated with discomfort.
