~Lavage.~--When lavage is necessary the patient must be allowed to rest after the process before being given food, otherwise it is apt to be vomited. ~Instructions to Nurse.~--The treatment for gastric ulceration is thus seen to be strenuous. In the beginning the patient is placed on a liquid or semi-solid diet, or is not fed at all for a time. This is done that the diseased organ may have a chance to adjust itself as far as possible and to give the physician an opportunity of studying the changes taking place in that organ. During the course of the disease the general symptoms which develop from time to time, causing more or less pain and discomfort to the patient, are nervousness, which in some individuals amounts to melancholia, extreme anemia and an utter distaste for food, all of which require patience on the part of the physician, the nurse, and the patient herself to overcome. The nurse must see that the patient is not disturbed or made unhappy by having business or home cares talked over in her presence; she must be kept as cheerful and as comfortable as her condition permits and urged to use care in her diet. After the ulcer is healed, to prevent a return of the trouble she must be warned against eating too fast or when over-tired, and she must be advised against very hot and highly seasoned foods, for, in the observance of these simple common-sense precautions only is she even in a measure saved further attacks. ~Special Diets Used for Gastric and Duodenal Ulcer.~--There are several well-known diets used in these conditions. Among those that have been found most satisfactory may be mentioned the Sippi diet, the Lenhartz diet. All of these diets require the most careful adjustment as to regulation of intervals of feeding, type of food material used, and method of preparation and administration of food. The treatment is directed toward the reduction of the free hydrochloric acid in the stomach in order that the ulcer may have an opportunity for healing.
