霍乱吐下，利止后，更发热。伤寒其脉微涩，本是霍乱，今是伤寒，却四五日，至阴经

病后邪气未散，阴阳尚虚，因为劳事，致二气交争，阴胜则发寒，阳胜则发热，故寒热
往来，有时休作，而成疟也。
此谓大渴饮水，而小便多也。其人先患劳损，大病之后，肾气虚则热，热乘之则肾燥，
肾燥则渴，渴则引水，肾虚则不能制水，故饮水数升，小便亦数升，名曰渴利也。
大发汗后，因复下之，则亡津液，而小便反利者，此为上虚不能制于下也。虚邪中于肺

这就是所说的风毒湿气，停滞在肾经。肾主管腰部和脚部，现在肾脏受湿邪影响，所以脚部软弱无力且浮肿。如果此人小肠有积热，就会导致小便排泄不畅，气机上逆；脚弱同时伴有气上逆，这就构成了香港脚（一种以足胫肿重、软弱无力为主要表现的疾病）。
霍乱出现呕吐和腹泻，在利止之后，又出现发热。伤寒脉象微涩，原本属于霍乱，现在是伤寒病，过了四五日，病邪传入阴经，转入阴经应当出现下利。如果病人平素就有呕吐和下利的症状，则预后不良（难治）。如果病人感觉想要大便，却反而只是排气而不能排便，这是病邪归属于阳明经的表现，大便必然干硬，经过二十二天会痊愈。之所以这样，是因为经气运行完毕的缘故。下利之后应当大便干硬，大便干硬如果能进食的就会痊愈。现在反而不能进食，等到下一个经气周期中稍微能进食了，再过一个经气周期能进食，超过这一天应当痊愈。如果不能痊愈，说明病邪不属于阳明经。恶寒、脉浮而后出现下利，下利停止后必定导致亡血（阴血亏虚）。
疾病之后邪气尚未消散，阴阳两虚，因为从事劳累之事，导致阴阳二气相互争斗，阴胜则发冷，阳胜则发热，所以寒热往来，有时发作有时休止，从而形成疟疾。
这就是所说的极度口渴饮水，而小便量多的情况。此人先前患有劳损，大病之后，肾气虚弱产生虚热，热邪乘袭导致肾燥，肾燥则口渴，口渴则引水饮用，肾虚则不能制约水液，所以饮水数升，小便也排出数升，这种病症称为渴利（消渴类疾病）。
大发汗之后，又使用攻下法，导致津液亏损，而小便反而通利，这是因为上焦虚损不能制约下焦所致。虚邪侵袭肺部，导致肺痿病。想咳嗽却咳不出，吐出浑浊的涎沫，这是肺痿病的表现。
This refers to wind-toxin and dampness stagnating in the Kidney Meridian (Shen Jing). The Kidneys govern the waist and feet; now that the Kidneys are affected by dampness, the feet become weak and swollen. If this person has excess heat in the Small Intestine, it leads to difficult urination, causing Qi to ascend upward. With foot weakness accompanied by ascending Qi, this constitutes Hongjiao Jiao (Hongjiao Jiao, a disease characterized by swelling and weakness of the lower legs and feet).
After vomiting and diarrhea from Huoluan (Cholera-like disorder), fever recurs after the diarrhea stops. In Shanghan (Cold Damage), if the pulse is faint and choppy, it originally belonged to Huoluan, but now it is Shanghan. After four or five days, when the pathogen enters the Yin meridians and transitions into Yin, diarrhea should occur. If the patient habitually suffers from vomiting and diarrhea, the prognosis is poor (intractable). If the patient feels the urge to defecate but instead only passes flatus without stool, this indicates the pathogen belongs to the Yangming stage, where stool will likely be hard. Recovery occurs after twenty-two days. This is because the meridian cycle has completed its course. After diarrhea, there should be hard stool; if the patient can eat with hard stool, they will recover. If they cannot eat now, but can slightly eat during the next meridian cycle, and can eat fully after passing one more cycle, they should recover on the day following that. If they do not recover, the pathogen does not belong to Yangming. Chills, floating pulse followed by diarrhea, and cessation of diarrhea lead to loss of blood (deficiency of Yin blood).
After an illness, pathogenic factors have not dissipated, and both Yin and Yang remain deficient. Engaging in labor causes the two Qi (Yin and Yang) to contend. When Yin prevails, chills occur; when Yang prevails, fever occurs. Thus, alternating chills and fever appear, occurring at intervals, forming Nuojue (Malaria).
This describes extreme thirst with drinking water, yet frequent urination. The patient previously suffered from Lao Sun (consumptive disease). After a major illness, deficiency of Kidney Qi generates heat; heat attacks causing Kidney dryness; Kidney dryness causes thirst; thirst leads to drinking water. Due to Kidney deficiency, water cannot be controlled; thus, drinking several sheng of water results in excreting several sheng of urine. This condition is named Kelii (Thirst-Diabetes).
After severe sweating, followed by purgation, body fluids are depleted, yet urination becomes surprisingly free. This is due to Upper Jiao deficiency failing to control the Lower Jiao. Deficient pathogens attack the Lungs, resulting in Fei Wei (Lung萎/Flaccidity Disease). The desire to cough but inability to do so, while spitting turbid saliva and foam, indicates Fei Wei disease.
Pathogens lodge in the Lungs. The Lungs govern voice and connect with Qi. Now, external pathogens struggle with True Qi. Since True Qi is deficient and pathogens are excessive, voice becomes obstructed.
Pathogenic heat attacks the Kidneys, causing Yin Qi deficiency. Yin Qi deficiency leads to dreams of sexual intercourse. The Kidneys store Essence (Jing). Now, Kidney deficiency fails to secure Essence, leading to seminal emission during dreams.
