MORNING SICKNESS.--Nausea, with or without vomiting, occurs so frequently in pregnancy that most women think it a natural accompaniment of their condition, relying upon it as a diagnostic symptom. It may begin the day following conception, but usually appears from the sixth to the eighth week. It is unlike nausea which accompanies biliousness, fevers, the effect of drugs, or even sea-sickness. It is a nausea that one feels from the crown of the head to the soles of the feet; one is “sick to the stomach” all over. Asking the cause of this, ninety-nine out of a hundred aver they believe it to be natural, and more than all, not to be avoided. Besides, the _grandmother_ of the neighborhood has told them that on account of this, the child will be more healthy, and the delivery easier. Facts do not bear her out in either assertion. _The real causes_ are to be sought in the violation of physical laws, in dress, diet, exercise, etc. The conditions are, first, an irritation in the womb caused by some existing derangement, which by sympathetic or reflex action is communicated to the stomach, and second, that state commonly called biliousness. The whole body is supplied with nerves distributed from the brain and spinal column. Besides these, ganglia of sympathetic nerves communicate with all nerves and with each other, being so interlaced that almost every part of the body is in communication with every other part. It is really a complete system of telegraphy. Both the uterus and stomach are remarkable in their supply of nerves, and any disturbance in the former is instantly conveyed to the latter. It is not unusual that an inflammation or displacement of the womb gives no local symptoms--but by reflex action there are headaches, indigestion, neuralgia, and various ailments. So, of the gravid uterus, if from any existing local disease or any cause in the system, it does not take kindly to its new function, and derangement in the organ ensues, instead of causing local pain and distress it will be communicated to other organs, most frequently to the stomach, producing nausea, vomiting, as well as often acute suffering. What is _biliousness_? Ladies, you know the condition to which you apply this term. Frequent headaches, aversion to food, aching of the bones, languid, sleepy and tired feeling. You get up in the morning weary, cross, irritable, out of sorts with everybody, and everybody retaliates by being out of sorts with you. What has happened in the human organism? What do you understand by biliousness? Listen to the answers. One says, “It is an overflow of bile,” others, “Too much bile,” “The liver don’t act,” “The bile has reverted back to the blood,” “The bile is secreted by the stomach,” “Too high living,” etc.
