It is produced most frequently by errors in diet. It may be caused by an unnatural position of the womb or uterus, by nervousness, constipation, or by too much exercise or too little exercise. The physician should be consulted as soon as it is observed to be a regular occurrence. He will eliminate by examination any anatomical condition which might cause it; or will successfully correct any defect found. When the cause is defined his instructions will help you to avoid any error of diet, constipation, or exercise. Many cases will respond to a simple remedy,--a cup of coffee, without milk, taken in bed as soon as awake will often cure the nausea. The coffee must be taken while still lying down,--before you sit up in bed. If coffee is not agreeable any hot liquid, tea, beef tea, clam bouillon, or chicken broth, or hot water may answer the purpose, though black coffee, made fresh, seems to be the most successful. Ten drops of adrenalin three times daily is a very certain remedy in some cases, though this should be taken with your physician's permission only. If the nausea occurs during the day and is accompanied with a feeling of faintness, take twenty drops of aromatic spirits of ammonia in a half glass of plain water or Vichy water. Sometimes the nausea is caused by the gradual increase of the [81] womb itself. This is not usually of a persistent character and disappears as soon as the womb rises in the abdominal cavity at the end of the second month. Nausea frequently does not occur until toward the end of pregnancy. In these cases the cause is quite different. Because of the size of the womb at this time the element of compression becomes an important consideration. The function of the kidneys, bowels, bladder, and respiration may be more or less interfered with, and it may be desirable to use a properly constructed abdominal support, or maternity corset. These devices support and distribute the weight, and prevent the womb from resting on or compressing, and hence interfering with, the function of any one organ. If the womb sags to one side, thereby retarding the return circulation of the blood in the veins from the leg, it may cause cramps in the leg, especially at night, or it may cause varicose veins, or a temporary dropsy. The correct support will prevent these troublesome annoyances; a properly constructed maternity corset is often quite effective. The diet should receive some special attention when these conditions exist. Any article of diet which favors fermentation (collection of gas) in the stomach or bowel should be excluded. These articles are the sugars, starches, and fats. It can readily be understood that if the bowels should be more or less filled with gas, or if they should be constipated, it will cause, not only great distress, but actual pain. Regulation of the diet, therefore, and exercise (walking best of all) will contribute greatly to the avoidance of these unnecessary sequelae.
