This hormone would be at an increased level in a mother who is breast feeding:
Correct answer: B. Prolactin
- A. Thyroxine
- B. Prolactin
- C. Aldosterone
- D. Insulin
Explanation
Prolactin levels increase in breastfeeding mothers due to the hormone's role in milk production. Breastfeeding stimulates the release of prolactin from the pituitary gland, promoting milk synthesis in the mammary glands. Elevated prolactin levels support the continuous production of breast milk to meet the demands of nursing infants, ensuring adequate nutrition and sustenance for the newborn. This hormonal response is essential for successful lactation and the well-being of both mother and child.
