CHAPTER XI THE FEEDING OF ADULTS IN DISEASES OF THE GASTRO-INTESTINAL TRACT ACUTE AND CHRONIC GASTRITIS ~Predisposing Factors.~--The majority of diseases affecting the stomach have as their predisposing factors, and owe their development to, one or all of the following conditions: (1) errors in diet; (2) disturbed secretory processes; (3) disturbed motility and tone. It is probable that in the beginning the first factor was the chief offender in the case, bringing about the development of one or both of the other conditions. The other factors to be considered in this respect are heredity, occupation, poverty, and diseases which involve to a greater or lesser degree the digestion of the stomach and intestines. A child may inherit a weakened organism through excesses or disease on the part of the parent. If this weakness is not overcome while the child is growing, the probabilities are that the digestion steadily declines until in adult life it becomes a pathological condition. Lack of fresh air, poor and dirty food, unwholesome surroundings, crowded and badly ventilated sleeping rooms, insufficient water, and overwork, all act in making the digestion bad. These must be overcome if permanent good is to result. ~Errors in Diet.~--Errors in diet arise more often through ignorance than from any other cause. A child may be allowed to eat any and all kinds of unwholesome and unsuitable food. When the stomach rebels, showing the serious danger signals of nature, medicines are given but the diet is unheeded, until the time comes when even the medicines fail to give temporary relief, and the organs of digestion are in some instances permanently impaired. ~Disturbed Secretory Processes.~--Consensus of opinion goes to show that the majority of cases of acute and chronic gastritis (catarrhal) and gastric ulceration are due primarily to a disturbance of the secretory processes, while the impaired motility and lack of tone in the stomach probably influence their development and aggravate the disease already present.
