Human milk is normally milky white, but sometimes other colors can occur, and here are possible reasons for the different colors of milk:
1. Milky white: This is the color of milk under normal circumstances, and the normal milk that babies eat contains protein, lactose, fat, antibodies and other main ingredients.
2. Clear or light yellow: Colostrum (the first milk produced in the first few days after giving birth) may appear transparent or yellowish, which contains more protein and immunoglobulins.
3. Blue or green: Occasionally milk may appear blue or green, perhaps because of high copper content in the milk or because bacteria in the mouth are mixed with the milk.
4. Brown or dark red: This may mean that there is blood in the milk. During pregnancy and breastfeeding, sometimes milk is mixed with blood when it is discharged due to blockage of the milk duct orifice or other reasons.
5. Pink: This may indicate a cracked or injured nipple, causing blood to mix into the milk. It may also be a manifestation of some serious conditions, such as breast malignancy, mastitis and other diseases.
In addition, it should be noted that if the mother produces only a small amount of breast milk for a period of time after giving birth, and it appears transparent or light yellow, this is a normal situation, also known as "colostrum". Colostrum is secreted in the first few days after giving birth, and it is rich in nutrients and antibodies, which is conducive to the healthy development of newborns. Colostrum is somewhat similar in color to honey and is usually clear or light yellow, which allows newborns to adapt better to the new environment and strengthen the body's immunity.
In addition, in the pre- and post-secretion of colostrum, the color of some nipple secretions may appear yellowish, brown or green, which is normal. However, if the color of the discharge is still bizarre or there are other abnormalities in the breast, such as redness, pain, lumps, etc., you need to see a doctor promptly.
In short, under normal circumstances, human milk should appear milky white or light yellow, rich in nutrients and antibodies, extremely important for the healthy development of infants. If other colors of milk or abnormal breasts appear, it is recommended to seek medical examination in time for timely detection and treatment.
