_Indigestion_, however, with undue formation of acids proper, or acids unnatural, to the stomach, is a much more annoying affliction than slow digestion. The sufferer from indigestion may be debilitated, anemic, may have a general want of tone; or he may be a more or less vigorous and plethoric person. In some cases flatulence is very troublesome. But the most usual symptoms are heartburn, acid eructations that produce burning sensations, sour taste at intervals or constantly in the mouth, setting the teeth on edge. In the more vigorous or plethoric sufferers a gouty diathesis may exist, which may result in a tendency to inflammation, bringing on neuralgia, rheumatism, gout, etc. Tongue more or less foul; uric acid in the system; confusion in the mind; headaches; pains in the loins, legs and feet; in fact, more or less shifting pains everywhere: these are the common exhibits of indigestion. On the whole, the sufferer is a victim to an irritable body and a fretful mind, necessitating the cultivation by him of patience and the effort to be agreeable. Besides the symptoms mentioned, indigestion may also be accompanied by gastric pain or by uneasiness at the pit of the stomach. It may be a sense of fulness or tightness, or a feeling of distention or weight, or again, a feeling of emptiness, goneness or sinking. Now and then there are burning, tearing, gnawing, dragging sensations under the breast-bone; and there is a general complaint of a capricious appetite, heartburn, vomiting, nervous headache, neuralgia and cold extremities. Other symptoms are pain from lack of food at the proper hour, or from food taken at the improper time; both of which practices may be followed by flatulency, occasioning a swollen, drum-like condition of the stomach and abdomen; the body of the tongue will be coated white, while the edges will present a redder appearance than in health. _Impaired digestion_ with nervous symptoms--in which the morbid sensibility of the mind is apparently the greatest--is called _hypochondria_. This class of sufferers, whose bodily and mental ills and morbid fears are so chaotically interwoven, are deserving of much consideration. So numerous are their fears and so fertile are their reasons for the many changes they arbitrarily make in their efforts to get well or keep from getting worse, so obstinately sure are they of being always right--that we can but give them our sincerest pity. In some cases the functional troubles of the stomach and mind are aggravated by disease of the pelvic organs, which adds to the depression of the mind through nervous sympathy with the abdominal organs. Dr. Cullen says on this point:--
