“Starvation,” or “inanition,” may be considered as being acute or chronic according as the requisite food has been suddenly and completely or gradually withheld.
ACUTE STARVATION.
The complete deprivation of food induces a series of modifications of the functions of the body, differing somewhat from those developed by a partial and prolonged deprivation. The length of time during which complete absence of food can be endured varies with circumstances. In absolute stoppage of the food supply the acute sensations of hunger pass away after the first one or two days, and are succeeded by profound functional disturbances with weakness and depressing sensations over the epigastric region, accompanied by distressing thirst.[953] The mouth is dry and the tongue heavily coated; the breath is fetid; the skin is harsh, dry, and exhales a disagreeable odor; the feces become more and more scanty until the latter days of life, when diarrhœa usually supervenes; the face and extremities become rapidly emaciated; the person walks with a weak and tottering gait;[954] the urine is small in quantity and very acid; muscular feebleness gradually reaches complete inability to move; ringing in the ears, insomnia and, in some cases, hallucinations[955] with delirium and convulsions precede death, though these latter symptoms are not uniformly observed.[956]
“CHRONIC STARVATION,” “CHRONIC INANITION.”
This form of starvation, met with most extensively during the prevalence of famine, also occurs in conditions demanding legal investigation.
The symptoms are sufficiently constant and characteristic. Emaciation becomes extreme, the skin dry and rough, exhaling a disagreeable odor and often covered with a coating not entirely attributable to filth; the breath is fetid and offensive. With some exceptions, the victim retains his consciousness and ability to move about, muscular efforts becoming more and more feeble; the voice becomes faint; the evacuations infrequent, dry and dark; the urine scanty and high-colored, death occurring suddenly at the end, with delirium in some cases.
The length of time during which these symptoms are developed and their intensity depend mainly upon the amount and character of the aliment actually supplied during the period before death.
Upon the PULSE and CIRCULATION the effects of starvation are manifest in increased frequency and feebleness of the cardiac contractions and lessened force of the cardiac impulse; this is more and more marked as the anæmic condition becomes profound. In some cases the pulse is greatly reduced in frequency, as well as in force, dropping as low as thirty-seven beats in the minute,[957] and auscultation reveals the existence of cardiac bruits.
In connection with enfeeblement of the circulation, a tendency to hemorrhagic conditions is common, with purpuric and petechial eruptions in some cases.
Temperature.—A subnormal temperature is frequently noted in the progress of chronic wasting disease. In inanition, which in some respects induces a similarly profound disturbance of the functions of nutrition, an analogous lowering of the body temperature occurs. Chossat clearly shows in his experiments the influence of starvation in depressing the body temperature. This abasement of temperature does not remain constant, but daily oscillations appear, differing from those occurring in conditions of normal alimentation.
