Part 107

The integrity of intestinal digestion depends upon the normal performance of all the preceding stages of digestion. Perfect insalivation, mastication, and gastric digestion are necessary to a proper action of the intestinal juices. The first rule of treatment in the chronic form is to examine into the condition of the mouth and teeth--to insist upon a slow and thorough mastication of food, especially of starchy food. Mastication is under the control of the individual, and he refuses to exercise this salutary means of prevention and cure at his own risk. The habit of chewing on both sides should be cultivated. All habits which waste and weaken the saliva should be given up, as smoking, chewing, and needless expectoration. Where the teeth are imperfect they should be attended to; false teeth should replace absent ones. All means should be used for improving gastric digestion: complete solution of food here means easier work for the intestine, and sometimes the cure of intestinal indigestion by removal of its cause. The rules which more directly bear upon the subject of intestinal dyspepsia are these: All the causes which have acted to bring about the disease should be removed. A change from a hot climate to a cooler and dry one will sometimes have an immediate good effect. Especially is this the case if travel is combined with change of scene. The substitution of exercise for inertia, of fresh for confined air, and the abandoning of occupations and habits of dress which hinder the freedom of movement of the abdominal muscles are of the highest importance. The patient should be made to cultivate pleasure instead of work if his mind has been overtaxed in his profession or business. Relaxation of the strained energies is indispensable to recovery. This rule is as applicable to school-children as it is to the overworked adult, man or woman. The benefits of travel, with change of scene and air, cannot be overestimated. Pedestrian tours in the mountains for young men, a trip to Europe for men and women in middle life, will secure the best results. For men who work much with their brains nothing is more conducive to aiding intestinal digestion than manual labor in the garden or workshop as a recreation. Exercise on horseback is pleasurable and improves a sluggish abdominal circulation. Rowing is good for younger men if it is confined to the field of pleasure, and is not made a task. For very feeble persons, especially for women, massage serves the purpose of exercise. The Swedish movement cure expands the thorax and abdomen, hastens the circulation, and quickens all the functions of nutrition and secretion.

A course of treatment would be incomplete without suggestions as to bathing. Life at the seashore would be of little service without the daily plunge in the surf. Still salt-water bathing is better for children and {633} delicate women. The reaction should be thorough to secure the best results. It is much to be regretted that hydrotherapy is not available and is not made use of more generally. A well-managed establishment where appropriate regimen and good and sufficient food could be combined with the renewal of the tissues by bathing would be of great advantage in all forms of indigestion. Nearly all of the benefit derived from the Hot Springs of Arkansas in chronic cachectic diseases follows upon the immediate improvement of the digestion and nutrition. The Warm and Hot Springs of Virginia have an equally good effect upon torpid abdominal functions. The Russian bath, the very hot bath, the cold plunge, the cold douche to the back or abdomen, and the cold pack to the abdomen, are means which may be employed at home for inducing a revolution ending in reform in the state of the digestive organs.

Irregularity in the hours of eating is of so much injury that rules must be given to enforce uniform habits. Instead of the light breakfast and heavy dinner, a good breakfast, a midday dinner, and a light tea are to be preferred. It is of much value to regulate the appetite according to the needs of the body and to avoid excess in everything. In this disease eating too little or starvation to a moderate degree gives that rest to the intestine which is necessary to its restoration to health.

The selection of the food should not be left to the patient; the dietary should be chosen for him with a view to lessening intestinal labor. In general terms, this should consist of a moderate amount of albuminoid food of the most digestible kind, and of farinaceous food and fats in an acceptable and digestible form. In other words, as the intestine digests proteids, starch, and fats, no exclusive diet can be devised which will secure a perfect result. In each case the examination of the stools and experience with different articles of diet must be made the means for determining upon a suitable regimen.

The exclusive milk diet is the best starting-point in feeding a patient suffering from acute or chronic indigestion. In addition to the fact that milk has all the elements of a perfect food, it contains sugar and fat in the most favorable condition for absorption; the casein of milk alone requires transformation into peptone. The pancreatic juice has the greatest activity in its effect upon milk, as is easily demonstrated by the artificial digestion of milk by pancreatic extract. In milk, therefore, we find a most easily digestible and most highly nutritious food for such cases. Instead of milk with cream, skimmed milk will be found sometimes to serve better the purpose of an exclusive diet, because it has less fat and because larger quantities can be taken without distaste or a sense of repletion. Koumiss may be added to the milk diet; it is digestible, palatable, and nutritious.

The peculiar and very active diastatic ferment of pancreatic juice converts starch into sugar very readily. Farinaceous articles of diet can be added to milk with advantage. Digestion takes place more slowly and more thoroughly in consequence, and an additional article of nutriment is obtained. Thus, milk can be diluted with a thick gruel of barley or oatmeal, or some of the best of the various artificial foods can be stirred in. To the milk diet may be added animal broths or soups prepared with vegetables, animal jellies, or some of the ready-prepared beef-essences. They may not in themselves be highly nutritious, but they contain at least {634} the salts of meat, and act as stimulants to the appetite and to the secreting glands.

Such a rigid diet cannot be kept up for a very long time without change; the appetite craves variety. Therefore solid albuminoid food in small quantity may be added to milk and farinaceous diet. Sweetbread boiled in milk, without dressing of any kind, is well suited for a beginning of animal diet. Oysters for some palates make an agreeable variety without putting much strain upon the digestive powers. They should be eaten uncooked, as cooking in any way renders them less digestible, and for greater precaution the hard part, or the adductor muscle which serves to keep the two shells together, should be removed. Fish boiled or plainly cooked and eaten without sauce is very easily digested. White-fleshed fish which has but little fat incorporated with the muscle-fibre is to be preferred. The patient may have eggs uncooked or slightly boiled, but one to two daily will be as much as he can well digest. The meat of poultry and game, especially that from the wings and breast, may be given even in a very feeble state of the digestive organs. When a more solid or satisfying diet is craved the patient may have beef or mutton cooked rare. Tripe and rabbit are suitable to some cases.

Bread, one day old and made light and porous, need not be denied the patient. Toast disagrees with some. To many, well-made biscuits or crackers are agreeable.

Vegetables should be given in small quantities, as the intestine is almost solely the seat of their digestion, and excess will tax too much a function which should be allowed as much rest as possible. The green vegetables contain less starch, and are therefore to be preferred. Lettuce, cabbage, kale, spinach, and celery come under this class, but even these are to be given to patients under treatment in moderation, with the intention of pleasing the palate rather than for purposes of nutrition. Macaroni and rice are easily digested.

Fruit contains very little nitrogenous matter and much water, and therefore has but little nutritive value, but it may be given to relieve the tedium of a restricted diet of milk or broths. Grapes, oranges, figs, strawberries, blackberries, raspberries, and peaches are the most digestible. But fruit should never be given as food. Fruit-juices, especially if acid and fresh, are unobjectionable. Coffee should not be allowed; its effect upon the nervous system is sufficient objection to its use. Tea can be given diluted largely with milk; cocoa, racahout, and broma are nutrient and make pleasant drinks. Sugar need not be excluded if used sparingly, and butter and oil in moderation may be permitted.

If the stomach is not disturbed thereby, wine may be taken with food to excite appetite. But except in the case of those who have always taken it, and cannot do without it, it is better to dispense with alcohol altogether. A red wine well diluted with water is a pleasant addition to the meal. Old wine is to be preferred to new, as being softer and less alcoholic. Good pure American wine from California or Virginia will answer the purpose when reliable French wine cannot be secured.

The value of mineral waters in the treatment of indigestion is great, but without proper dietetic regimen they can accomplish but little. The good results following a visit to Saratoga, Bedford, or other watering-place are due to other causes than the waters. In combination, however, {635} with the advantages of change of scene, air, good hours, and a simple diet the mineral waters aid in bringing about a cure. They are especially useful in men who drink too little water at home, in gouty and plethoric subjects, and in states of acid stomach digestion and chronic constipation. The alkaline and saline waters are the best, the former containing a notable proportion of the carbonate or bicarbonate of sodium, potassium, or lithium--the latter having neutral salts in considerable quantity.

The articles of food to be avoided are pastry, cheese, much butter or fat, meat richly dressed or over-cooked, pork, veal, lobsters, crabs, vegetable matter in excess, very cold or very hot fluids or solids.

All of the methods so far described are designed to accelerate the circulation in the abdominal organs and in the tissues generally, to quicken the secretory and nutritive processes, and to give to the intestinal secretions the foods which they can most readily digest. In the event of such means failing to accomplish the desired end, is there any direct stimulus which can be brought to bear on the intestinal glands concerned in digestion? The pancreas being the most active and most important of these, it would be desirable to have some agent which could excite its gland-structure to greater activity. Sulphuric ether has been found to have this effect; it may be given before meals. The salivary secretion begins pancreatic digestion (the digestion of starch), and therefore its outflow should be stimulated at the same time; but thorough mastication does this usually without need of further aid.

When all plans fail to secure a thorough digestion in the intestine, and unaltered food and fat are passed, while the patient grows thinner and feebler daily, artificially-digested food may be given. The intestine is thus relieved of labor, and time is given for a restoration of activity by rest and an improved tone of all the tissues and organs. Rice, bread, baked flour, potatoes, or barley may be given in combination with malt extract, which converts starch into grape-sugar and dextrin.

As pancreatic juice acts both upon proteids and starch, an extract of the pancreas has a more general application than an extract of the stomach--pepsin. Roberts of Manchester has given full directions for the method of digesting food by pancreatic extract. Beef, milk, and the farinacea may be digested, the albuminoid substances being changed into peptones, the starchy matters into dextrin and sugar, capable of being absorbed readily with but little or no further alteration in the digestive tract. Pancreatic emulsion (Dobell) is another method of giving fat emulsified.

A less successful way of gaining the same object is by administering the pancreatic extract internally. The difficulty lies in conveying the extract (the ferment of which is destroyed by the acid gastric juice) through the stomach in safety. This chemical danger is thought to be obviated by giving the extract one to two hours after eating with a {636} protecting guard of an alkali, the bicarbonate of sodium; but the mechanical difficulty of securing direct transit through the stomach to the intestine early enough and in quantity enough to digest the duodenal contents is as great as the chemical obstacle. It is very doubtful whether this method of use can be of any real service.

In those cases in which the form of indigestion is due to, or is associated with, a deficient hepatic secretion--a condition indicated by offensive and light-colored stools and other symptoms--it is advisable to stimulate the liver to increased secretion. It is probable that the same remedies which excite a flow of bile do at the same time stimulate the pancreas. The best of these are euonymin, sanguinarin, iridin, ipecacuanha, colocynth, jalap, podophyllin, sodium sulphate, and potassium sulphate. Sodium benzoate, ammonium benzoate, and the salicylate of sodium are also powerful hepatic stimulants. As one of the purposes of the bile is to create the alkaline medium necessary for pancreatic digestion, the administration of an alkaline solution in full doses, as in the form of mineral water, when gastric digestion is finished, may make amends for the lack of bile. A combination of an antiseptic and the alkali may to some extent supply the deficiency still better, as the bile is the antiseptic of the intestinal canal.

Atony of the intestinal wall leads to flatulence, colics, and constipation, and would be a cause of indigestion if none other existed. It is to be treated by the general rules already given, by electrical stimulation of the abdominal muscles with the faradic current, or by the effort to stimulate the intestinal wall more effectively with the galvanic current. Strychnia in small doses should be given for some time. In women of relaxed muscular fibre with enlarged abdomens an elastic belt may be worn with advantage.

After the special aids to the parts concerned in digestion, tonics are called for to combat the general want of tone and anæmia. The saccharated iron, the carbonate, potassio-tartrate, lactate, pyrophosphate, or the ferrum redactum may be given. The syrup of the iodide of iron is the best form for children. The bitter tonics are inadvisable except for loss of appetite in cases where the stomach is not disordered. Quinia is available in a large number of cases in which malarial influence plays a part. Strychnia is a good general tonic, and may be prescribed combined with mineral acids, particularly with the dilute hydrochloric acid.

The special symptoms which call for treatment are flatulence, abdominal pains, and constipation. All the remedies already described are directed toward their relief. But sometimes they appear in so exaggerated a form as to need immediate attention. The many remedies for colic and tympanitic distension which have the property of relieving spasm and absorbing gas find application in these conditions. Constipation is not to be treated by laxatives if it can be avoided. But the bitter waters, Friedrichshall, Pullna, Hunyadi Jânos, and Rakoczy, by exciting bile outflow, are sometimes of undoubted curative value.

The form of dyspepsia called strumous, as it occurs in children of anæmic appearance with dry skin covered with minute scales, and with bad breath and light ill-smelling stools, demands a very thorough and {637} persevering treatment. The advantages of climate must be sought--seashore in summer with bathing, dry and moderately warm air in winter. Outdoor life in the sun, with active exercise, is to be had at the expense of education within-doors. Study is not good for children of this class except when health is made paramount to it. Cod-liver oil, either pure, in phosphatic emulsion, or in the pancreatic emulsion, is a necessity. Malt extract with the hypophosphites is beneficial. The food must be carefully selected, and the child educated to a varied diet, including fats. The skin should be anointed daily with cocoanut oil, olive, cottonseed oil, or cod-liver oil.

CONSTIPATION.

BY W. W. JOHNSTON, M.D.

SYNONYMS.--Costiveness, Fecal retention, Fecal accumulation, Alvine obstruction, Obstipation. Ger. Koprostase, Stuhlverstopfung, Hartleibigkeit, Kothstanung. Fr. Constipation, Paresse du ventre, Échauffement. It. Constipazione. Older synonyms: Constipatio vel obstipatio alvi; Alvus tarda, dura, adstricta; Tarda alvi dejectio; Obstipatio alvarina; Stypsis; Coprostasis (Good).

NATURE AND DEFINITION.--The act of defecation is almost wholly due to the working of an involuntary mechanism which may be set in play by the will, and is in part dominated by it, but which is frequently independent and uncontrolled by volition. Deep inspiration, closure of the glottis, downward pressure of the diaphragm, and contraction of the abdominal muscles are accessory, but not essential, to the expulsion of feces from the rectum. In certain persons, and occasionally in all persons, especially in diseases where the fecal mass is in a semi-fluid or fluid form, the strongest effort of the will cannot resist the expulsive contractions of the rectal muscle. The sphincter is kept in a state of tonic contraction by a nervous centre situated in the lumbar portion of the spinal cord. The fecal mass, supported by the bladder and the rectum, does not at first touch the sphincter; the rectum is usually empty; but when the column has been well driven into the rectum peristaltic action is excited in the rectal walls and the sphincter is firmly pressed upon. The lumbar sphincter centre is now inhibited, and the ring of muscle opens, the accessory and voluntary muscles contract, and the expulsive act is completed. In the well-ordered and healthy individual the rectal walls and the sphincter do not receive the maximum of irritation from pressure of the advancing column but once in twenty-four hours. The habit of having one movement in each day is, it may be believed, in accordance with the natural and physiological demand, although both the number and the hours of evacuating are fixed to a great extent by education. The habit once established, the mechanism of expulsion recurs at the same hour and entirely without the direction of the will. If the desire be resisted, it will be most apt not to return until the same hour on the next day.

Defecation depends for its normal character upon the healthy functioning of the organism, but especially upon the normal processes of digestion. The character of the rectal contents as to composition and consistence, and the time of the arrival of the mass at the sphincter, are {639} regulated by the taking of food at stated hours and by its normal digestion and absorption. Unaltered or partly-changed remains of the ingesta pass down the bowel, mingling with the secretion from the intestinal glands and with mucus and epithelium. As this mass passes into and through the colon, being propelled by regular peristaltic waves, it acquires odor from the development of a substance which is a final product of the putrefaction of albumen. Gradually the more fluid elements are absorbed, and in the descending colon a less fluid or semi-solid consistence of the feces is reached. A healthy digestion and assimilation, with active and regular contractile movements of the muscular walls of the small and large intestines, are essential to normal defecation.
