The important rule with regard to the mental attitude of the patient toward uncomfortable feelings due to digestion must be, first to correct all other possible sources of the trouble, and only after these have been proved not to be factors in the case, should there be any question of modification of diet. This is just the opposite rule from that which obtains, and by which patients begin to meddle with their diet at the slightest symptom, or supposed symptom, of indigestion. My custom is to tell patients at once that there is probably something else besides their diet at fault. It is not that they eat too much, nor too great a variety, but that perhaps they eat too rapidly. Without reducing their diet, and above all without eliminating supposedly indigestible things from it, there should be formed a habit of eating more slowly. This will usually result in the reduction of the quantity eaten, but the variety of food should be the same, and the patient should not be permitted to limit his diet to a few supposedly bland, unirritating materials. In that event, constipation will assert itself, particularly if there is limitation of the amount of fluid taken.

Longevity of Dyspeptics.—There is one consolation that may be given to nervous dyspeptics, though in the midst of their worst symptoms they may not be sure whether it is a genuine consolation or not. It has been noted that many of those who live to extreme age tell the story of having suffered from nervous dyspepsia in middle-life. Their solicitude about themselves makes them safe against over-indulgences of many kinds in food or drink that might prove hurtful to them. Much of their discomfort is indeed due to the fact that they do not eat quite enough. If they succeed in avoiding the {260} pitfalls of the infectious diseases, and especially tuberculosis during their earlier years, and most of them are likely to because of the great care they take of themselves, they often live to old age. Certainly of two men, one of whom eats very heartily and the other very sparingly, the latter is much the more likely to attain old age. There are those who declare that the valetudinarian life, "half dead and alive," which even Plato satirized nearly 2,500 years ago, ever renews the question as to whether life is worth living or not. It is particularly dyspeptics who seriously discuss this question—yet with all their complaints, they actually do live longer lives.

Pharmaceutic Remedies.—This insistence on the importance of mind in the treatment of indigestion does not imply that tonic remedies, and especially such substances as strychnin, which stimulate appetite and add tone to the muscles of the stomach, should not be used when duly indicated. They are always helpful. Alone, these remedies give but temporary relief and after a short time the system becomes accustomed to them. If prescribed in connection with changes in the patient's habits, and especially such as divert his attention from his digestive tract, and from wrong persuasions as to food taking, the good they accomplish will be lasting. Nervous people usually have an increase of acidity. They are liable to overdo everything, and even the stomach overdoes its acid forming function. For this, alkaline remedies such as rhubarb and soda will do good. But, just as with strychnin, the benefit is but temporary unless the patient's habits and attitude of mind are modified so as to eliminate their solicitude as a constantly disturbing factor.

Circumstantial Suggestions.—There are many changes of habits that are of great value in the treatment of nervous and allied forms of indigestion. These changes often make a great difference in the general health of the patient and thus help to improve digestion. Besides their influence as alteratives, they are valuable from the mental influence which they exercise. It requires a definite exertion of will many times, perhaps, each day to bring about the omission or performance of certain actions, and this act of the will is accompanied by the repeated suggestion that this will cause improvement in the digestion. Many of the cures effected by special diet. Habits of exercise, health resort regimes and the like, owe their efficacy to this accompanying repeated suggestion of acts for the formation of new habits or the breaking of old ones.

Physiological Measures.—There are, of course, certain details with regard to digestion in which the patient's mental attitude needs to be changed by instruction rather than persuasion, by knowledge of physiology rather than by psychology. In the taking of food itself, chewing is, of course, the most important consideration after its good preparation by the cook. If patients are told to chew their food carefully, however, without further directions than this, it will usually be found that they begin to chew their meat a great deal and their vegetables scarcely more than before. It is, however, vegetables that must be chewed particularly. The meat-eating animals bolt their food. They have only cutting and tearing teeth. Their instinct is correct, for the saliva has nothing to do with the digestion of meat, and therefore no chewing is necessary. On the other hand, the vegetable-eating, and especially the grain-eating animals, chew carefully. Most of them are ruminants, that is, after a preliminary thorough chewing of their food, they swallow it, and then {261} afterwards at their leisure bring it up once more into the mouth and chew it again.

Mastication and the Stomach.—If food is not chewed well, and occurs in large masses in the stomach, not only is it not dissolved easily, but the work of passing it out to the intestine is delayed. The reflex which brings about the opening of the stomach and the ejection of food into the intestine is best brought about by the liquefaction of the stomach contents. During the mixing process all the food, as far as possible, becomes fluid and then is passed on. Large pieces of any kind are delayed, however, hamper the emptying of the stomach and interfere with stomach motility. The stomach is only a thin-walled membranous viscus which finds difficulty in dealing with food in lumps. It is different from the stomach of the hen, which, having no teeth, swallows grains of all kinds without chewing, but also by instinct swallows small stones which, in its thick-walled, muscular gizzard, are used for grinding up the food.

Exercise.—The taking of exercise is an important habit that needs to be changed in the case of dyspeptics. Many of those who live a sedentary life, and are much occupied with intellectual or business matters, are almost sure to take little or no exercise. If earlier in life they were accustomed to take much, the lack of it leads to serious disturbances of nutrition. They have formed certain habits as to the amount of food they eat, and these continue, so that they consume more heat-making material than they can use. In the process of dissipating it, there is likely to be much nervous energy wasted, usually to the discomfort of the patient. This is likely to be eventually reflected back to the stomach, with disturbance of appetite and digestion.

We now know that the motor function of the stomach is much more important than its secretory function. Its main purpose is to mix the food and pass it on in small quantities, at intervals, to the intestines. When patients have a sense of uncomfortable fullness in the gastric region after a hearty meal, or of discomfort after the taking of food, especially if much liquid is taken with it, they are prone to attribute these feelings to imperfect secretion not completing digestion as it should, and permitting fermentation with a production of gas and consequent stomach distention. The real reason for their discomfort is not secretory, but motor. It is due to a delay in passing on the food and to stomach distention because the gastric muscle is not in good tone.

People who have been used to taking exercises have their muscular system in good tonic condition. This includes the involuntary muscles, as well as the voluntary, and if they are neglecting air and exercise, the whole muscular system becomes flabby. Hence the uncomfortable sense of distention, because the stomach walls do not contract readily for the expulsion of food. A second important factor is also present—the muscles of the abdomen. Ordinarily they support the abdominal organs without any sense of effort. If by lack of exercise they have diminished in tone, however, when a hearty meal is eaten, the abdominal muscles have to support this additional weight since the stomach itself sags, and the consequence is a feeling of pressure on the left side of the abdomen about the level of the umbilicus. To relieve this feeling the tendency of the patient is almost always to lessen the amount eaten. If he is not distinctly overweight this will do harm rather than good. Instead he {262} needs to take sufficient exercise to tone abdominal muscles and reflexly also tone even involuntary muscles, and with them the gastric muscularis.

Air.—Almost more important than exercise is an abundance of fresh air, and without this muscles soon fail to respond to voluntary or involuntary impulses. If people do not spend two or three hours in the air every day, they are likely to develop an over-sensitive condition in which all nervous sensations are exaggerated. The reason men and women differ so markedly in their reaction to pains, aches and discomforts, is mainly that their habits of being out in the air differ correspondingly. Men are out much and, as a rule, stand discomfort better. Women are out little and are more sensitive to pains and aches. The more a man is out, the less is he likely to notice discomforts and aches that he would otherwise complain about.

Sleep.—Another important factor is the amount of sleep. Over and over again I have found that patients who were beginning to complain of discomfort, which they associated with the word indigestion, were taking too little sleep, and as soon as I persuaded them to add an hour or more to their sleep their gastric symptoms began to improve. It is easy in our large cities to acquire the habit of shortening the hours of rest. This is sometimes done so gradually that the individual scarcely realizes how much he has cut into his sleeping period. Some people who have to get up at seven or half-past seven in the morning go to bed about twelve, but really do not get settled for sleep until nearly one o'clock. Sometimes people read interesting books just before going to bed, or while in bed, and it is nearly two o'clock when they get to sleep.

Many people have the habit of reading themselves to sleep. This may be an excellent way to get rid of bothersome thoughts, provided the reading selected is not of too absorbing a character, and provided also as soon as sleepiness comes its call is heeded. Some write letters late at night. Writing always keeps one awake, though reading may be helpful for sleep. If this abbreviation of sleep becomes habitual, the first organs in the body to set up an objection is the digestive tract. It is one of the hardest worked systems in the body, having to dispose of its quantum of food three times every day, and if the organism does not receive due rest, the digestive tract suffers first. People who get insufficient sleep often have no appetite in the morning, and suffer from uncomfortable feelings in the gastric region. What they are too prone to do is to meddle with their diet, and this practice always does harm.
