Breast Milk not Flowing (and Acute Mastitis)

CHAPTER 53 Breast Milk not Flowing (and Acute Mastitis)



This condition consists of scanty or absent breast milk after childbirth. I have preferred the term ‘Breast Milk not Flowing’ to ‘Insufficient Lactation’ or ‘Agalactia’ because the last two terms both imply a deficiency, a lack of a vital substance; lack of breast milk, however, may be due not to a deficiency of milk but to an obstruction or stagnation that prevents the flow of milk.




Pathology


The pathology of insufficient or absent lactation can be clearly differentiated between deficiency and excess: breast milk may be deficient because its source, Blood, is deficient; or there may be enough milk but it does not flow properly due to stagnation of Qi in the breast. Fu Qing Zhu places a special emphasis on distinguishing between the two main causes of insufficient lactation: a deficiency of Qi and Blood; or stagnation of Qi in the breast. He also places special emphasis on the role of Qi in lactation.


To transform breast milk from Blood needs Qi’s action and to express it needs Qi’s power. This situation could be compared with that of water being pumped out of a reservoir: there may be plenty of water (breast milk) in the reservoir, but if the pump (Qi) is inefficient, the water will not flow.


Fu Qing Zhu says:



Breast milk is a product deriving from the transformation of menstrual Blood by the Directing and Penetrating Vessels (Ren and Chong Mai): these two vessels are the source of menstrual blood below, and of breast milk above. Zhang Jing Yue says in his Complete Works of Jing Yue (1624):



The Stomach channel also plays a role in lactation as it controls the breast as a whole, while the Liver channel controls the nipple. Fu Qing Zhu says: “Breast milk is transformed from Yang Ming [channel] which pertains to Earth.3


While the main Empty cause of insufficient lactation is deficiency of Qi and Blood, the main Full cause of insufficient lactation is stagnation of Liver-Qi. As mentioned above, the Liver controls the nipple and it easily overacts on the Bright-Yang Channels (Wood overacting on Earth). Lactation relies on the power of Qi to transform Blood into milk and to express the milk properly. When Liver-Qi stagnates, it may hinder the flow of Stomach-Qi in the breast and create stagnation there with symptoms of distension, pain and milk not flowing.


Fu Qing Zhu emphasizes the role of stagnant Liver-Qi in hindering Stomach-Qi in the breast and it is significant that Dr Fu mentions “stagnation in the Bright Yang [Yang Ming]” rather than Liver-Qi stagnation. He says:



Thus, Fu Qing Zhu clearly identifies emotional problems as the chief cause of stagnation of Liver-Qi. The Literati’s Care of their Parents (Ru Men Shi Qin) by Zhang Zi He (1156–1228) also says: “Crying, weeping, sadness, anger, depression, may all cause the breast vessels not to flow.5


Thus, we can also see the pathology of Breast Milk not Flowing in terms of Qi and Blood, with the former either deficient or stagnant and the latter only deficient (see Figure 53.1).



In terms of differential diagnosis, Breast Milk not Flowing should be distinguished from Breast Carbuncle (Ru Yong) which is also characterized by insufficient lactation but, in addition, by systemic signs such as shivers, fever, joint pain and a feeling of oppression of the chest: Breast Carbuncle corresponds to acute mastitis in Western medicine.
