痢疾出现肛门坠胀感时，不可单纯使用降气之法；便下脓血时，不可单纯使用行血之法。唯有调和气机、和营养血，并辅以导滞消积的药物，这才是治疗妊娠痢疾的关键法则。
腹部胀满且疼痛，伴有里急后重（腹痛窘迫，时时欲便，肛门重坠，便出不爽）。选用三黄解毒汤，加入木香、当归。（寒性方剂第20首）
腹部有沉重下坠感，是元气虚弱所致；胎动不安，是内热炽盛所致。选用补中益气汤，加入黄芩、白芍。（补益方剂第6首）
痢下黄色稀水，是脾气下陷所致。选用补中益气汤。（补益方剂第6首）

肠鸣、肛门坠胀，肛门疼痛。选用蒙姜黄连丸。（和解方剂第16首）

血液壅滞影响胎元，导致脾阴虚，不能运化水谷，从而发生泄泻；另外，胎元系于肾，胎儿窃取肾中之气，导致肾阳不足，寒气上蒸脾土，也会导致脾虚泄泻。即使偶尔有风、寒、暑、湿等外邪侵袭，也多半属于脾肾亏虚所致。
大便虚性急迫。这是脾土燥热、大肠涩滞所致。适宜调理脾胃与大肠，药用川黄连、干姜、木香、甘草。
呕吐、腹痛，手足逆冷。这是寒水反侮脾土所致。选用六君子汤（补益方剂第1首），去掉半夏，加入补骨脂、益智仁、煨鲜姜。

Post-tenesmus should not be treated solely by descending Qi; passage of pus and blood should not be treated solely by promoting blood circulation.

(Tonify category, No. 31) If Rougui (Cinnamomi Cortex) is considered detrimental to the fetus, it can be replaced with Roudoukou (Myristicae Semen) and Tusizi (Cuscutae Semen).

Weakness of the Stomach and Intestines with wind pathogens lodging within. Weifeng Tang (Stomach-Wind Decoction). (Disperse category, No. 15)

Blood stasis affecting the fetal root leads to Yin deficiency of the Spleen, resulting in the inability to transform and transport water and grain, causing diarrhea. Furthermore, the fetus is anchored to the Kidney; if the fetus steals Qi from the Kidney, Kidney Yang becomes insufficient, allowing cold to steam upward into Spleen Earth, also leading to Spleen-deficiency diarrhea. Even if there are occasional invasions by wind, cold, summerheat, or dampness, these are mostly attributable to deficiencies of the Spleen and Kidney.
Deficient urgency in defecation. This is due to dryness of Spleen Earth and涩 (obstruction/stagnation) of the Large Intestine.
