Postpartum Lochia Lasting for Months: The Problem May Not Be "Failing to Properly Observe the Confinement Period"

Many people believe that postpartum lochia lasting for months is due to "not observing the confinement period properly," overexertion, or eating the wrong foods. In fact, this is not necessarily the case. From the perspective of Traditional Chinese Medicine (TCM), lochia is the residual blood and turbid fluid discharged during the process of uterine recovery after childbirth. Whether it is completely expelled and when it finishes are not merely reflections of "how well one has rested" — they are more fundamentally related to the state of qi and blood and the recovery of the Chong and Ren meridians. Clinically, it is not uncommon for lochia to persist for two to three months or even longer. The root of the problem often lies not in "insufficient rest," but in a disruption of the body's internal dynamic balance.

So what exactly does this "balance" refer to? Why do some people who are clearly very careful about resting still experience lingering lochia that refuses to stop?

1. Postpartum Persistent Lochia: First Distinguish Between "Incomplete Expulsion" and "Inability to Retain"

In TCM, lochia is understood through two major pathological directions: "blockage" (bù tōng) and "failure to contain" (bù shè). Blockage refers to blood stasis retention — the path that should be cleared is obstructed, manifesting as scanty, dripping discharge with dark color and clots, accompanied by stabbing pain in the lower abdomen. Failure to contain refers to qi deficiency with loss of containment — analogous to a riverbank that is too low or a sluice gate that cannot close tightly, manifesting as copious, pale, thin discharge with a pronounced bearing-down sensation in the lower abdomen. These two conditions require fundamentally opposite treatment approaches — one needs "dredging and unblocking," the other needs "consolidating and containing." If the primary and secondary aspects are not distinguished clinically, and hemostatic herbs are indiscriminately used for all cases of persistent lochia, one may actually "close the door and detain the culprit," trapping blood stasis inside.

According to traditional TCM theory, the production and discharge of lochia are closely related to the fullness of qi and blood in the Chong and Ren meridians. The Qing dynasty physician Zhang Jingyue (Zhang Jiebin) discussed this in his work Jingyue Quanshu · Gynecology Standards (Furen Gui):

"Postpartum persistent lochia may be due to blood heat, qi deficiency, or blood stasis... Blood heat should be cleared, qi deficiency should be supplemented, and blood stasis should be expelled."

This passage identifies three common causes of persistent lochia: blood heat disturbing the Chong and Ren, qi deficiency with failure to contain, and blood stasis causing obstruction. Blood heat can be further differentiated into excess heat and deficiency heat — excess heat is often related to excessive consumption of pungent, warm, and drying foods after childbirth, while deficiency heat typically stems from depletion of yin and blood. Clinically, among cases of postpartum lochia persisting for months, the most common pattern is qi deficiency with concurrent blood stasis, while pure blood heat accounts for a relatively smaller proportion. What does this indicate? It suggests that the core of this problem most often lies in the two characters: "qi" and "blood."

Since qi and blood are so crucial, why is the postpartum body particularly prone to "qi deficiency" and "blood stasis"?

This brings us to childbirth itself. Delivery consumes qi and damages blood, while birth trauma readily leaves behind stasis. Thus, the natural state of the postpartum body is one of "dual deficiency and dual stasis." As stated in the Jingui Yaolüe · Pulse Patterns and Treatment of Postpartum Diseases in Women (Furen Bing Mai Zheng Zhi):

"New mothers are susceptible to three ailments: the first is convulsions, the second is dizziness and blurred vision, and the third is constipation."

Although Zhang Zhongjing enumerated three different postpartum conditions, their root causes all point to the same core issue — loss of blood and damage to body fluids, with sudden deficiency of qi and blood. Consider this: qi is the driving force that propels blood circulation, and blood is the material foundation that nourishes the viscera. When both are deficient after childbirth, the propulsive force is insufficient, giving rise to the situation where "what should be expelled is not completely eliminated." The retained blood stasis, in turn, impedes the generation of new blood, creating a vicious cycle of "deficiency giving rise to stasis, and stasis aggravating deficiency."

Does this mean that simply supplementing qi and nourishing blood can solve the problem? The matter is probably not that simple.

2. Behind Lingering Lochia: A Deeper Imbalance of Visceral Function

When postpartum lochia persists for months, a deeper investigation at the visceral level reveals two most common patterns: "spleen qi deficiency with qi sinking" and "liver qi stagnation with blood heat." These two patterns precisely correspond to the two major categories of pathogenesis: "failure to contain" and "blockage."

2.1 Spleen Qi Deficiency with Qi Sinking: Qi Fails to Contain Blood, Chong and Ren Not Consolidated

The spleen governs transportation and transformation, serves as the source of qi and blood production, and also has the function of containing blood. After childbirth, if dietary habits are improper, if there is excessive anxiety and overthinking, or if one resumes strenuous activities too early, the transportation and transformation function of the spleen and stomach becomes impaired, and the containing capacity of qi declines. When qi fails to contain blood and the Chong and Ren are not consolidated, lochia will drip incessantly. Individuals with this pattern often present with a sallow complexion, mental fatigue, generalized weakness, shortness of breath upon exertion, lochia that is pale in color and thin in consistency, and a bearing-down sensation in the lower abdomen. Clinically, it is necessary to first determine whether qi deficiency or blood deficiency is dominant — if qi deficiency is prominent, treatment focuses on strengthening the spleen and supplementing qi; if blood deficiency is prominent, blood-nourishing approaches should also be incorporated. Although the two often coexist, the emphasis differs in each case.

2.2 Liver Qi Stagnation with Blood Heat: Heat Disturbs the Chong and Ren, Forcing Blood to Move Recklessly

Postpartum emotional volatility, depression and anger injuring the liver, or excessive consumption of pungent, warm, and tonifying foods can all cause heat to accumulate in the Liver Meridian. Heat pathogen disturbs the Chong and Ren, forcing blood to move recklessly, which can also lead to prolonged, unremitting lochia. Common manifestations in this pattern include lochia that is deep red or dark purple in color, thick in consistency, with an abnormal odor, accompanied by irritability, easy anger, dry mouth, bitter taste, and fullness in the chest and hypochondrium. The pathway of the Liver Meridian is quite interesting — it courses along the hypochondriac and rib regions, encircles the genitalia, reaches the lower abdomen, and intersects with the Chong and Ren meridians in the abdominal region. Therefore, when liver qi becomes depressed and transforms into heat, the heat pathogen can easily travel along the meridian to directly disrupt the uterus.

Interestingly, the spleen deficiency and liver qi stagnation patterns are often not isolated in clinical practice. The spleen corresponds to Earth and the liver to Wood, and Wood can overcome Earth — when postpartum overthinking damages the spleen first, spleen qi becomes deficient, and liver wood may take advantage of this weakness to attack spleen earth. Conversely, liver qi stagnation can also affect the transportation and transformation function of the spleen and stomach. The Huangdi Neijing · Suwen · Chapter on the Correspondence of Yin and Yang in the Natural World (Yinyang Yingxiang Da Lun) provides a vivid metaphor for this:

"Anger injures the liver, but sadness overcomes anger... Overthinking injures the spleen, but anger overcomes overthinking."

From the perspective of the five-element generation and control cycles, excessive anger injures the liver, yet anger can also restrain the damage that excessive rumination inflicts on the spleen. This reminds us that postpartum emotional regulation and the recovery of the spleen and stomach are inherently inseparable — when emotions are suppressed and unsettled, the function of the spleen and stomach often weakens accordingly, transportation and transformation become dysfunctional, the source of qi and blood production is depleted, and lochia will naturally be even more difficult to expel completely.

In light of such intricately intertwined conditions, how does TCM approach the direction of "regulation"?

2.3 Mixed Deficiency and Excess: Dispersing Stasis and Generating New Blood in Parallel

Clinically, in cases of postpartum persistent lochia, neither pure qi deficiency nor pure blood heat is particularly common. More frequently seen is a mixture of deficiency and excess — with both the aspect of qi deficiency failing to contain and the aspect of blood stasis causing internal obstruction. This is consistent with the postpartum physiological characteristic of "dual deficiency and dual stasis." Therefore, TCM treatment emphasizes "simultaneous attack and supplementation" — neither blindly applying heavy tonics (which may cause stagnation and exacerbate heat), nor recklessly using aggressive dispersing agents (which may damage healthy qi). As stated in the Fu Qingzhu's Gynecology · Postpartum Section (Fu Qingzhu Nüke):

"For postpartum persistent lochia... one must not hastily use astringent and consolidating herbs, for fear that if blood stasis has not been completely cleared, it may instead be retained and cause stagnation."

The principle is "if blood stasis is not removed, new blood cannot be generated." However, if one only focuses on eliminating stasis while neglecting to supplement deficiency, healthy qi will be further depleted and transportation and transformation will become weakened, which is equally detrimental to recovery. Therefore, the therapeutic rhythm emphasizes "first unblock, then supplement; supplement with unblocking incorporated." As for the specific degree and scale, these must be determined by a licensed TCM practitioner based on individual constitution and pattern differentiation.

At a deeper level, whether lochia is completely expelled within a reasonable timeframe reflects the process of uterine involution. For the uterus to recover, it relies on the propulsion of qi and the nourishment of blood. If qi is insufficient, there is no force to propel; if blood is insufficient, there is no substance to nourish. Thus, genuine TCM treatment does not focus on "lochia" itself, but rather on the smoothness of qi and blood circulation behind it. This is analogous to a river with poor flow — the crux of the problem may lie in insufficient water source, sediment accumulation in the channel, or a section that is too narrow. The outward manifestation is the same — "water not flowing" — yet the treatment approaches differ considerably.

From clinical patterns, postpartum lochia persisting for months is more commonly seen in individuals who experience chronic sleep deprivation, heavy mental rumination, or who resume a hectic work schedule too early after childbirth. Such individuals often concurrently present with fatigue, lethargy, light and fragmented sleep, and irritability. Additionally, improper postpartum diet — such as blindly consuming warming and drying foods — may also promote heat and move blood, causing lochia to "drag on." Traditional Chinese medicine has always attached great importance to postpartum dietary precautions, but what specifically suits or should be avoided by an individual must be determined in light of their constitution. The more prudent approach is: before lochia has completely resolved, avoid overly warming, drying, and pungent foods, allowing the body to naturally complete its cleansing process.

There is another layer that is easily overlooked: "cold." After childbirth, the body is deficient. If daily living is not attended to carefully, cold pathogen may take advantage of the deficiency to invade. Cold is contracting and congealing in nature, which can impede the smooth discharge of blood stasis. This is precisely the opposite direction from the blood heat that forces blood to move recklessly described earlier — one is congealing due to cold, the other is moving due to heat. Therefore, clinical pattern differentiation must employ the four diagnostic methods in an integrated manner, carefully discerning the color, consistency, and odor of the lochia, as well as whether the lower abdomen prefers pressure or rejects it, in order to identify the true pivotal issue.

Returning to the misconception at the beginning — postpartum lochia lingering for months is truly not as simple as "not observing the confinement period properly." It is more like a letter from within the body, reminding you: qi and blood need replenishment, stasis needs to be cleared, and visceral functions need to rediscover their rhythm. Have you ever considered that lochia that refuses to stop may not merely indicate that the uterus "has not recovered well"? It may also be your body telling you — during this period, you have been too exhausted, your qi and blood cannot keep up, and you need to pause and listen carefully to what your body is truly saying.
