Most frequently it will be found that there is nothing serious the matter. The vomiting ceases or, at least, it becomes less troublesome as soon as the diet has been more carefully arranged, constipation has been corrected, or other hygienic details, such as outdoor recreation and mental diversion, have received the attention requisite for good health. In a much smaller group of cases the restoration of the womb to a proper position or the treatment of some other local condition, which can generally be remedied without difficulty, is all that is necessary. But finally, in extremely rare instances, the vomiting of pregnancy is due to a definite disease whose existence may be recognized by special methods of analyzing the urine. In any case, if the physician is given an opportunity to make the necessary observations and thus determine the variety of the vomiting, no time will be lost in beginning effective treatment. In an overwhelming majority of the cases, as I have said, nothing serious will be found; and then the control of the vomiting will lie within the power of the patient herself. Since nausea is usually experienced in the morning on rising from the recumbent to the upright posture, measures to prevent an attack should be begun even before the patient raises her head from the pillow. In the first place something to eat should be taken as soon as she awakens. The most satisfactory results follow eating two or three pieces of crisp toast or a Bent's cracker (sold by grocers), either of which should be thoroughly chewed and swallowed without taking anything to drink. Good results are also obtained, though less uniformly, from eating other food, such as fruit, oatmeal, or eggs. The benefit secured from this procedure is explained, perhaps, by the activity of the digestive organs and the effect of that activity upon the circulation of the blood. The food eaten before rising is not intended to take the place of breakfast, which ordinarily will be eaten later. Furthermore, it is essential to remain in bed until half an hour after the food was taken; and not to rise then unless perfectly comfortable. Anyone who is inclined to be nauseated should get up slowly and dress leisurely, sitting down as much as possible while putting on the clothes. If breakfast is not desired at once, it should not be forced, but some food should be eaten between early morning and noon. It is an exceedingly good rule to bend every effort toward escaping the initial attack of nausea, for in this way one soon gains confidence, and overcomes the depressing habit of being continually on the watch for the symptom, lest she be taken unawares. Exceptionally, however, patients feel more comfortable if they vomit in the morning; this may be helpful, for example, if a large meal has been eaten just before retiring the previous night.
