The action of the heart is disturbed as in stomach indigestion. Irritability of the heart and palpitation are in part due to anæmia and in part to mechanical pressure and reflex influences. The nervous, anæmic, thin dyspeptic has among his chief troubles a throbbing heart, which keeps him awake at night and fixes his attention upon this organ as the seat of his disease. The general circulation is languid; cold hands and feet and cold sweats testify to this, and the irregularity or suppression of catamenia follows upon the irregular blood-supply.
The urine is usually high-colored, has an abnormally high density, is acid, and on cooling deposits lithates, uric acid, and oxalate-of-lime crystals. The urine is most heavily loaded with sediment when digestion has been recently completed. Therefore, the morning urine after a heavy dinner of the night before contains the largest amount of lithates. Albuminuria is occasionally a symptom of indigestion in the bowel. The eating of cheese or pastry in excess may cause it.13 Seminal emissions at night frequently occur. The action and reaction upon each other of this perversion of the sexual function, the indigestion, and the mental disorder, reduce the poor sufferer to a most pitiable condition of despondency and prostration.14

14 The writer has observed cases in which an exaggeration of the sexual instinct in men of middle age was associated with intestinal indigestion.
Anæmia is one of the earliest indications of impaired nutrition. It precedes loss of flesh and the wrinkled and dry condition of the skin which may be a marked symptom in cases of long standing. Various eruptions appear on the skin. In the strumous dyspepsia of children the white, almost waxy, skin is covered with dry scales, which may be seen over the whole body from head to foot. No symptom is more characteristic of intestinal indigestion and of imperfect fat digestion and absorption than this. Eczema and psoriasis, pityriasis, impetigo, and porrigo decalvans are forms of skin eruption seen.
Closely allied to the symptoms caused by indigestion in the intestine are those due to functional disorder of the liver. The liver completes the work which the intestine has begun. It receives directly from the intestine blood laden with the products of digestion, and further transforms them into substances to be used in the economy. The symptoms which result from disturbances in the performance of these functions are, as has been said, closely connected with the symptoms of intestinal indigestion. This association is shown by the tendency among older writers to trace all such symptoms to the liver, the terms bilious and biliousness including all the phenomena of derangement of the function of digestion in the intestine, as well of the function of the liver. Later writers excluded the part of the liver to a great extent in giving rise to the so-called bilious symptoms. Recent physiological study has shown how closely the intestine and the liver are associated in health and in disease. When the liver is implicated in indigestion the symptoms which follow are due either to a deficiency of the secretion of bile, and the resultant disturbance of digestion in the intestine, or to a derangement in the transformation in the liver of the products of albuminoid digestion. When the disorganization of the peptones is imperfectly performed in the liver, instead of urea there is a production of lithates and lithic acid, constituting the condition called lithæmia. The lithates pass into the urine and are deposited. The occurrence of this urinary sediment after excesses and imprudences in diet is well known. The continuance of lithæmia leads to the development of symptoms more or less characteristic. These are a loss of appetite and coated tongue, flatulence, oppression after eating, and constipation. The nervous system is soon disturbed, and often to a marked extent. Vertigo, headache, disturbances of the special senses, sleeplessness at night, drowsiness during the day, annoy the patient and induce extreme hypochondria. He is worried, moreover, with numbness and tingling in one or both arms or in the legs, and hence spring fears of paralysis. The heart is disturbed in action, and is irregular and feeble. Emaciation in previously corpulent persons is not unfrequent.
COURSE, TERMINATION, AND SEQUELÆ.—Acute dyspepsia in the bowel lasts from a few hours to a day or two, and ends in leaving the patient as well as before. A diarrhoea of indefinite duration may follow.
Chronic intestinal indigestion in infants and young children often continues until the diet is changed to one suited to the powers of digestion. In adults interference with so important a function cannot but have the most serious results. While the progress is slow, lasting many years, there is a steady march from bad to worse.
