As Dhanvantari, the divine physician, addressed Sushruta, he began to explain the profound and intricate causes of abdominal diseases. “Listen carefully, O Sushruta,” he said, “for all diseases, and especially those of the abdomen, arise when the digestive fire, the very force that governs transformation in the body, becomes weak. When this fire falters, impurities accumulate within, and the vital airs—prāṇa and apāna—become obstructed. These winds, when unable to move freely, become agitated and flow irregularly, corrupting the very breath of life. When these vital breaths are disturbed, they affect the joints of the flesh, causing swelling in the belly and abdomen. Such swelling may manifest in eight distinct forms, depending on the humors involved—whether alone or in combination, or mixed with fluids arising from the spleen, groin, or wounds. Those afflicted become parched in palate and lips, and swelling extends not only through the abdomen but to all limbs. Movement, strength, and appetite are lost; the belly distends with wind, and the person becomes ghost-like in appearance—these are unmistakable signs. Hunger fades, and an aversion to all food arises. A burning pain torments the sufferer, who can no longer distinguish between digested and undigested food, and thus consumes what is unwholesome. The body’s strength wanes; breathing grows shallow; activity becomes minimal. The mind turns away from the joys of the senses, and sorrow and wasting set in. Pain persists in the bladder and joints, even when one eats only lightly. In this disease, old age and indigestion hasten the loss of strength. Lethargy and laziness descend, and drowsiness comes unbidden. Excretion becomes scant, and the digestive fire grows weaker still. Burning, swelling, and bloating plague the body, especially when water accumulates. In all watery places, death is near, and lamentation there can bring no relief. The abdomen, veined like a window’s mesh, gurgles with strange sounds. The navel becomes obstructed and pressured, eventually destroyed. Wind brings pain to the heart, waist, navel, anus, and groin. The wind escapes noisily, but urine is scant; there is no excessive craving, and the mouth becomes tasteless. In abdominal diseases caused by wind, swelling appears in the hands, feet, face, and belly. Pain arises in the groin, sides, abdomen, waist, back, and joints. A dry cough develops, along with body ache, heaviness below, and an accumulation of impurities. The skin darkens or takes on a reddish hue, and the mouth loses its sense of taste. When pain splits the abdomen, blue-black veins spread and become visible; the bloated belly produces strange noises. Here, the wind moves in all directions, causing pain and sound. When bile is the cause, fever, fainting, burning, and bitterness in the mouth appear. Dizziness and diarrhea follow, the skin and other parts turn yellow, and the veins become yellow or coppery. Sweating and heat intensify, and the person feels perpetual burning. The skin takes on a smoky look, feels soft to the touch, and decay advances quickly. When phlegm is at fault, heaviness, sweating, and swelling dominate. Sleepiness and discomfort come, appetite is lost, breath is short, cough arises, and the skin turns pale. The abdomen looks cloudy and oily, covered with white and black veins. With excessive phlegm, the abdomen becomes hard, cold, heavy, and firm; all three doṣas—wind, bile, and phlegm—are provoked, and impurities from each taint the body. All these corrupt impurities, mixed with blood, gather in the abdomen. There, they transform, causing wasting, fainting, and dizziness. Thus arise threefold types of abdominal disease—each severe, maturing swiftly, and worsening especially in cold and windy conditions. Overeating, agitation, improper food and drink, unsuitable beverages, and the strain from vomiting or other illnesses all contribute to these disorders. The spleen, situated on the left side, may enlarge from its place, especially when increased by blood or other fluids, causing pain. It becomes hard as stone, excessively firm, rising up like the back of a tortoise, and gradually spreads across the abdomen. Shortness of breath, cough, thirst, bad taste in the mouth, bloating, fever, pallor, fainting, vomiting, burning sensation, and confusion accompany it. The afflicted spleen may appear reddish or variegated, tinged with blue and yellow; upward movement of wind, nausea, fainting, intense thirst, and persistent fever follow. Heaviness, loss of appetite, hardness, obstruction, and dizziness may even cause the spleen to shift from the left to the right side. When the liver is affected, and feces are retained in the rectum, distressing symptoms arise, some with difficult names, others simply as painful upward movements. When the downward wind in the abdomen is aggravated, it binds the stool, bile, and phlegm, causing fever and pain. Cough, breathlessness, chest pain, headache, pain in the navel and sides, constipation, loss of appetite, and vomiting—all these are caused by the disturbed abdominal wind. The abdomen becomes covered with firm, blue, and red veins; above the navel, a shape resembling a cow’s tail may appear. If the abdomen is pierced by bone fragments or other foreign bodies, the liver and other organs begin to decay, and fluid seeps out through these openings. If there is rawness or burning in the rectum, the fecal matter becomes scant, foul-smelling, slimy, yellow, and bloody. The remaining matter fills the abdomen, causing severe distress; it increases below the navel and quickly becomes watery. When the doṣas are greatly increased and pervade the body, along with breathlessness, thirst, and dizziness, this is called ‘perforated abdomen’—others call it ‘leakage.’ In those who suddenly indulge in unwholesome foods after consuming oily substances, who drink excessive water, have weak digestion, or are emaciated and very thin, the wind is obstructed from its natural path, and phlegm thickens with water. That very water increases, and from its essence, a drop forms and accumulates. This disturbance gives rise to swelling of the abdomen, accompanied by thirst, the flow of mucus, pain, cough, breathlessness, loss of appetite, and veins of various colors spreading across the body. Thus did Dhanvantari reveal, with clarity and compassion, the many forms and signs of abdominal disease, so that Sushruta and all who follow the healing path might recognize and understand them.
