The narrative begins with the description of a grievous affliction caused by the corruption of the bodily channels that carry breath, water, and food. When the wind within becomes vitiated and settles in the chest, it disrupts the proper digestion of food in the stomach, resulting in breathlessness. Early signs of this disorder include pain in the heart and along the sides, irregular breathing, distension of the abdomen, and splitting pain in the temples. These symptoms worsen with exertion and overeating. The impure wind, both driven and driving, begins to move in a reverse direction, ascending through the channels and expelling phlegm. It seizes the head, neck, chest, and sides, causing cough, rattling sounds, fainting, loss of appetite, and severe nasal congestion. The breathlessness becomes intense and rapid, tormenting the life-breath; the patient may faint from its force, but finds brief relief after spitting. The afflicted person finds it difficult to lie down and breathes heavily; when seated, he feels somewhat better. His eyes become wide, his forehead sweats, and he is greatly troubled. His mouth grows dry, he breathes repeatedly, desires warmth, and trembles. The condition worsens with cold clouds, water, the east wind, and phlegmatic states. This chronic darkness type may be cured in a strong man, but in those suffering from fever, fainting, or coldness, it does not subside easily. The sufferer, much like those with cough and breathlessness, experiences pain from injury to vital spots, sweats, faints, has abdominal distension, burning in the bladder, and disturbed sleep. His gaze turns downward, his eyes sink, the whites of his eyes are tinged with red, his mouth is dry, he babbles incoherently, loses his complexion, and falls unconscious. He breathes with a great, deep, pitiable sound, snorting and gasping, agitated like a maddened bull, ceaselessly. His knowledge and discernment are lost, his eyes and face bewildered; he draws his eyes together, his urine and stool are retained, and his speech is broken. His throat repeatedly becomes dry, and he suffers severe pain in his ears, temples, and head; he breathes out long and upward, but cannot draw breath back down. His mouth and ears are blocked with phlegm, his sense of smell is disturbed; he looks upward, his eyes wandering, casting glances all around. When the vital spots are injured, he laments, his speech suppressed. These symptoms, though unmanifest at first, may become manifest, and certainly bring death. At this point, Dhanvantari addresses Suśruta, promising to explain the origin of the disease of hiccup. Hiccup, he says, has a single cause, its preliminary signs, types, and dependence on constitution. Hiccups arise from food and are classified as minor, paired, or great; there is also a deep type caused by improper, hurried, or excessive consumption. When one is afflicted by dry, sharp, rough, or excessive food and drink, the breath produces a mild hiccup, with a soft sound, usually following hunger. The hiccup that arises together with food and drink at twilight is called 'paired.' When wind is disturbed by exertion, it produces a minor hiccup. The hiccup that spreads from the root of the neck, moving slowly, increases with exertion and becomes mild immediately after eating. The hiccup that arises after a long time, with paired impulses, increases in the mouth as it progresses and grows with each episode. The type that causes trembling of the head and neck is identified as 'paired,' and is accompanied by delirium, vomiting, diarrhea, and rolling of the eyes. The paired, forceful hiccup, which comes with progression, causes the brows and temples to droop, and disturbs hearing and sight. It stiffens the body and speech, takes away memory and consciousness, strikes the vital channels, and causes pain along their course. When there is bending backward and trembling, the great hiccup arises, bringing severe pain, loud sound, great force, and immense strength. It may also arise from the stomach or navel, as previously described. This type produces great yawning and stretching of the jaw; with a deep cause, the deep hiccup is difficult to cure. In the first two types, one should avoid the others; the forceful type shows all symptoms, especially in those who are old or sexually active. For one whose body is weakened by disease and emaciated from lack of food, all other ailments may be cured, but not so for one who acts rashly. Just as hiccup and breathlessness, when established at the time of death, remain fixed. Dhanvantari then declares that he will explain the origin of the disease yakṣma, which is accompanied by many other ailments and is preceded by numerous disorders. This disease is known as rājayakṣmā, kṣaya, śoṣa, and the lord of diseases. In ancient times, this affliction befell the king among stars and the twice-born ones. Because both 'king' and 'yakṣma' are present, it is called rājayakṣmā; it is called kṣaya due to the wasting of the body and vital substances, and arises from that cause. It is called śoṣa because of the drying up of fluids and so forth; it is the lord of diseases, like a king. It arises from rash actions, suppression of natural urges, and the depletion of semen, strength, and unctuousness. Abandonment of proper rules regarding food and drink—these four are its causes; by them, wind is provoked, and pitta is disturbed everywhere in vain. Entering the joints of the body, these disturbed forces press upon the veins, block the channels, or cause excessive discharge. They produce pain in the middle, upper, lower, and transverse parts of the body, and in the heart; the symptoms that arise are severe nasal catarrh and fever. There is excessive salivation, sweetness in the mouth, softness, impairment of digestive fire, craving for food and drink, and seeing pure and impure things alike. Food and drink are often contaminated by flies, grass, hair, and the like; there is nausea, vomiting, loss of taste, and weakness even after bathing. The hands, thighs, chest, feet, mouth, abdomen, and eyes become excessively pale; there is whip-like pain in the arms, burning of the tongue, and a repulsive appearance of the body. Thus, the scriptures lay out the progression, symptoms, and causes of these formidable diseases, imparting their wisdom through vivid and compassionate detail.
