Disease Groups and Suggestion.--Labeling groups of ailments with a single term gives rise to many unfortunate conclusions and dreads with regard to what a particular condition really is. The word "indigestion" is commonly used for any stomach discomfort or disturbance, especially that occurring after eating, from the slight distress because too much has been eaten, or the uncomfortable feeling of fullness because too much liquid has been taken, or the discomfort due to an unsuitable mixture of food materials, to such serious conditions as develop when there is motor insufficiency of the stomach, followed by dilatation, with delay of the food for long periods and with consequent fermentation, distress and bad breath. Whenever the word "indigestion" is mentioned, the patient may think of the worst cases that he has seen or heard of with this label, and concludes that while his ailment may not be very serious just now, it is only a question of time until it becomes so, and that unless he can get rid of his uncomfortable feeling he is destined to have one of the forms of "indigestion" that are productive of such serious discomfort, with probably ever increasing torment, until some fatal complication develops. The initial symptoms of gastric ulcer and cancer have been labeled indigestion, and people, often recalling the serious consequences that followed in such cases, fear for themselves. _Fearing the Worst_.--This looseness of terms is noted with regard to many other forms of disease. Rheumatism calls up the picture of advanced arthritis deformans, with the awful deformed joints and bed-riddenness, which should not bear the term rheumatism at all, but which the patient has heard called so. Catarrh is the simplest of inflammatory processes, meaning merely an increase of secretion, functional in character and without any serious disturbance of an organic character beneath it, but many people have heard the foul-smelling ozena called catarrh, at least popularly, and so the mental picture of such a repulsive progressive process as beginning in them is suggested. It is important, therefore, when using words that have such wide connotation as these, to explain exactly what is meant, and perhaps, better still, not to use the words, but to employ some more specific term that does not carry a cloud of dreads with it. Indigestion can be a very simple passing set of symptoms, but once certain people get the notion that they are troubled with indigestion, their minds dwell on it to such an extent that they are likely to limit their eating more than they should, and to disturb digestive processes by thinking about them and using up in worry nervous energy that should be allowed to flow down to actuate digestion.
