What three factors primarily influence milk secretion?

There is no established concept stating that milk secretion is primarily influenced by three specific factors. Milk production is mainly affected by hormone levels, breastfeeding frequency, nutritional intake, emotional state, and breast stimulation. These factors interact with each other to collectively determine the quantity and quality of breast milk. If there is severe insufficient milk supply, breast pain, or abnormal discharge, it is recommended to seek medical attention promptly.

1. Hormone levels: Prolactin is the key hormone promoting milk synthesis. Infant suckling and postpartum hormonal changes regulate its secretion. Conditions such as thyroid dysfunction or polycystic ovary syndrome may disrupt hormonal balance and thereby inhibit milk production.

2. Breastfeeding frequency: Frequent and effective infant suckling stimulates nerves in the breast, promoting prolactin release and increasing milk production. Prolonged intervals between feedings can lead to milk accumulation, triggering a feedback mechanism that reduces secretion and may even cause lactation to cease.

3. Nutritional intake: Adequate protein, high-quality fats, vitamins, and fluid intake are essential during lactation. Poor nutrition directly affects milk synthesis; for example, protein deficiency may result in watery milk and reduced volume. A balanced diet is crucial to ensure sufficient nutrient supply.

4. Emotional state: Negative emotions such as anxiety, depression, and excessive stress can impair hypothalamic-pituitary function, suppress prolactin secretion, and reduce milk production. Maintaining a positive and relaxed mood helps stabilize hormone levels and supports normal lactation.

5. Breast stimulation: In addition to infant suckling, proper breast massage and timely emptying of milk help maintain lactation function. Issues such as blocked ducts or nipple damage can reduce the effectiveness of suckling and indirectly affect milk production.

During lactation, breastfeeding should be done regularly, ensuring the baby fully empties one breast before switching to the other. The diet should include nutritious foods such as fish soup, eggs, and vegetables, along with adequate hydration. Avoid excessive fatigue and manage stress through activities like listening to music or talking with others to support healthy milk production.
