华佗云∶病患卧，遗屎不觉者死。
【大】产后出现大小便不通的情况，是因为产妇的肠胃原本就挟带有热邪，加上分娩时血液和津液同时流失，导致体内津液干枯枯竭，肠胃气机痞塞涩滞，热气结聚在肠胃之中，所以导致大小便无法排出。
【薛】曾经治疗一位产妇大小便不通，服用各种药物都没有效果，病情危急。让她饮用牛乳，一天后症状稍有好转并得以通畅，三天后痊愈。用人乳效果更好。

【心】治疗妇人产后，突然小腹胀大如蛊状，大小便不通。取气海穴、足三里穴、关元穴、三阴交穴、阴谷穴主治。
【薛】产后遗屎（大便失禁），如果是脾肾虚弱所致，使用还少丹，仍以补中益气汤为主方。若兼有虚寒症状，加用肉豆蔻、补骨脂，或者使用四神丸。若是脾肾虚寒，使用八味丸兼服四神丸，同时辅助以前提到的两个方剂。
按语：产后遗屎，是由于肾气不固所致，适宜用五味子丸主治。（参见杂病泄泻章节。）
有一位产妇大便不成形，饮食减少且没有食欲，有时清晨遗屎，这是中气虚寒，脾肾不足，使用补中益气汤送服四神丸而痊愈。
有一位产妇小便中排出粪便，名为大小肠交。这是由于气血俱虚，失去正常的运行规律，先用六君子汤两剂，又用五苓散两剂而痊愈。寻常的肠交症也可以使用此法。

华佗说：病人卧床，遗屎而不自知者，预后不良，主死。
[Da] Postpartum obstruction of both urination and defecation occurs because the intestines and stomach originally harbor heat pathogens. Due to the loss of blood and body fluids during childbirth, the body fluids become dry and exhausted. This leads to qi stagnation and涩 (astringency/stagnation) in the intestines and stomach, with heat qi knotting within them, thus causing the obstruction of both urination and defecation.
[Xue] I once treated a postpartum woman suffering from obstruction of both urination and defecation. Various medicines failed to produce any effect, and her condition was critical. I instructed her to drink cow's milk. After one day, her condition slightly improved and passage was restored; after three days, she recovered completely. Human breast milk is even more effective.
Taohua San (Peach Blossom Powder): Treats constipation of both urination and defecation caused by qi stagnation and blood stasis in the Bladder.
Tao Ren (Peach Seed), Kui Zi (Okra Seed), Hua Shi (Talcum), Bing Lang (Areca Seed) (equal parts).
Grind the above ingredients into a fine powder. Take 2 qian per dose, mixed with Scallion White Decoction on an empty stomach.
Treats postpartum difficulty in urination and defecation, accompanied by bleeding from the lower orifice.
Che Qian Zi (Plantago Seed), Huang Qin (Scutellaria Root), Pu Huang (Typha Pollen), Mu Li (Oyster Shell), Sheng Di Huang (Rehmannia Root), Shao Yao (Peony Root) (each 1 liang 5 qian).
Grind the above ingredients into a fine powder. Take a "fang cun bi" (a measure equivalent to a square inch spoonful) mixed with Rice Drink on an empty stomach. Avoid wheat products and garlic.
Tongqi San (Qi-Regulating Powder): Treats postpartum obstruction of both urination and defecation. The Umbilical Sealing Method can also be used. (See the section on Constipation in Miscellaneous Diseases.)
[Xin] Treats postpartum women who suddenly experience abdominal distension resembling a water belly (ascites/gu syndrome), with obstruction of both urination and defecation. Points Qihai (CV6), Zusanli (ST36), Guanyuan (CV4), Sanyinjiao (SP6), and YinGu (KI10) are indicated.
[Xue] Postpartum fecal incontinence due to Spleen and Kidney deficiency should be treated with Huanshao Dan (Return to Youth Pill), primarily using Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction). If there is deficiency-cold, add Rou Dou Kou (Nutmeg) and Bu Gu Zhi (Psoralea Fruit), or use Sishen Wan (Four Spirits Pill). If there is Spleen-Kidney deficiency-cold, use Bawei Wan (Eight-Ingredient Pill) combined with Sishen Wan, supplemented by the aforementioned two formulas.
Note: Postpartum fecal incontinence is caused by insecurity of Kidney Qi; Wuweizi Wan (Schisandra Berry Pill) is appropriate. (See Miscellaneous Diseases: Diarrhea.)
One postpartum patient had loose stools, poor appetite, and occasional morning fecal incontinence. This was due to deficiency-cold of the Middle Qi and insufficiency of the Spleen and Kidney. She recovered after taking Buzhong Yiqi Tang administered with Sishen Wan.
One postpartum patient excreted feces through the urethra, a condition named Da Xiao Chang Jiao (Intercourse of Large and Small Intestines). This resulted from joint deficiency of Qi and Blood and deviation from normal pathways. She first took Liujunzi Tang (Six Gentlemen Decoction) for two doses, followed by Wuling San (Five-Ingredient Powder with Poria) for two doses, and recovered. This method can also be applied to ordinary cases of intestinal crossing.
The Guangji text records a formula for treating postpartum fecal incontinence.
Take grass from old swallow nests, burn it to ash, mix with wine, and take half a cup. It can also treat men.
The Jiyan Fang records a treatment for postpartum fecal incontinence. It also treats men.
Fan Shi (Alumen, calcined), Mu Li (Oyster Shell, calcined) (equal parts).
Grind into powder. Take a fang cun bi mixed with wine, three times daily.
The Buyi text records a formula for treating postpartum fecal incontinence without awareness of its occurrence.
Bai Lian (Akebia Rhizome), Shao Yao (Peony Root) (equal parts, ground into powder). Take a fang cun bi mixed with wine.
The Buyi text states that for postpartum fecal incontinence without sensation, Guchang Wan (Intestine-Securing Pill) can be taken. (Formula see Miscellaneous Diseases: Diarrhea section.)
Hua Tuo said: If a patient lies in bed and has fecal incontinence without awareness, it indicates death.
