The forms of the complaint thus vary: In the one instance, there is a deficiency of the animal matter of the urine, namely, the urea, and in the other, a superabundance of it. In the former instance the urine is of a pale color, and transparent, and sometimes like clear water, with a very faint slight odor; whereas, in the latter it is generally of a higher color, and now and then so thick as to resemble brewer’s porter: it is decidedly a disease of great debility. The symptoms are, a wearisomeness and languor of the whole frame, a dry and crimpled state of the skin, a sinking, gnawing pain at the pit of the stomach, the bowels are obstinately bound, while a great thirst always prevails. The body wastes to a mere skeleton, the discharge of urine being almost constant, at least every hour, accompanied with a call that must be immediately obeyed: the leading feature in the composition of the urine, in addition to the varied presence of the urea, is the saccharine matter contained therein. It rarely attacks others than those who have led an irregular life, or else have suffered much from other kinds of sickness. Diabetes is supposed to depend upon a perverted action of the kidneys; but there is little dispute of its being a malady involving the whole process of animal economization. The quantity of urine got rid of in a day has been known to amount to ten quarts; as the disease continues, the patient becomes much emaciated, the feet swell, and he sinks into a state of low hectic fever; the urine discharged continuing all this time to exceed nearly double the amount of nourishment, liquid or solid, that is taken, has given rise to the idea, that water is absorbed from the atmosphere through the body. The disorder is generally lingering, and, unless conquered, at last fatal. The treatment embraces many remedies—bleeding, emetics, diaphoretics, and sedatives, are mostly employed. It being a complaint involving the necessity of constant professional watchfulness, a more lengthened dissertation upon its peculiarities will but little serve the patient. My own opinion is, that the invalid must look for recovery—presuming the initiatory symptoms have been duly attacked and subdued—to careful diet, fresh air, varied scenery, and cheerful society. Bathing, either vapor or warm, is immensely useful; and, among the cases that have travelled across my path (for patients laboring under diabetes, like any other chronic ailment, generally take the round of the profession), I have seen much and great good achieved by the frequent employment of the bath.
