2 Now at their commencements, it is easy to recognize at once what is an acute disease, and what a chronic one, not only as regards those which take a uniform course, but also when the course is variable. For when severe paroxysms and pains are causing distress without intermission, the disease is acute: it becomes evident that the future course will be prolonged when there are but slight pains and fever, and when there are long intervals between the paroxysms, and there are in addition the signs which have been described in the preceding book. It is also to be noted whether the disease is increasing, or stationary, or lessening, because some remedies are suitable for increasing, more for declining maladies; and when an acute fever is increasing in urgency, remedies which are suitable in decreasing affections are to be tried rather during the remissions. A disease is increasing in urgency when pains and paroxysms occur with more severity, and when they both recur at shorter intervals, and desist later than before. And, in chronic diseases too, even if they do not present such characteristic signs, it may be recognized that the affection is increasing: if sleep is irregular; if digestion deteriorates; if the stools become more foul; the sense duller; the mind more sluggish; if a feeling of cold, or of heat, runs through the body, if the body becomes more pale. But opposite signs mark a decline in the disease. . . . In acute diseases, moreover, the patient is to be given food after more delay, and not until the paroxysm is already declining so that its force may be broken primarily by the withholding of nutriment; in chronic diseases, earlier, so that it may support the patient for the duration of his coming illness. But if sometimes, not the whole body, but a part only, is affected, still the support of the strength of the whole body rather than the curing by itself of the part diseased is of more importance. It makes a great difference also whether from the commencement the patient has been treated correctly or incorrectly, because treatment has less advantage in those cases in which a course has been persisted in without effort. If a patient lives through indiscreet treatment with his strength unimpaired, an appropriate treatment may restore him forthwith.
