The treatment in chronic gastritis is very like that in the more acute form; that is, it must be combated by removing the cause. Lack of fresh air and exercise have much to do with the development of chronic gastritis, but even they combined with a judicious amount of rest would be wasted without a proper adjustment of the diet to cover the main points of the disturbance. As has already been mentioned, the cause may be a lack of gastric juice or it may be an excess of it; it may be intensified by an ~atonic~ condition of the organ or from the food passing too quickly into the duodenum. ~Test Meals.~--As a rule it is not safe to make a snap diagnosis as to the cause of this disorder. Since in many instances the more serious disorders may be traced to a disregard for nature's danger signals, the physician as a rule advises a test meal, this meal consisting of a glass and a half of water or a cup or two of tea without cream or sugar and from one to two slices of toast or water rolls. In from three-fourths to one hour or longer this is removed from the stomach by means of a stomach pump and analyzed, the result of the chemical and bacterial analyses forming the basis for diagnosis. This meal is generally given in the morning before any other food has been eaten.[92] ~Dietetic Treatment.~--The foods constituting the diet in chronic gastritis must be of the simplest character and prepared in the simplest manner. No fried foods are permissible. Pastries, griddle cakes, rich puddings and sauces, candies, and alcoholic beverages must be omitted from the diet as well as the following articles of food: pork, veal, shellfish except oysters, sardines, canned meats and canned fish, highly seasoned and spiced dishes, twice-cooked meats, vinegar, pickles, olives, cold slaw, pickled beets, catsup, mustard, coarse fibered vegetables such as cabbage, old onions, old turnips, and cucumbers, strong tea, coffee, or chocolate, rich cream or dishes made entirely of cream. In cases of excessive acidity due to a hypersecretion of HCl the extractives of meat are contraindicated, hence all gravies and outside parts of roasted meat must be omitted or limited in the diet.
