The vomiting of pregnancy usually takes the form of simple "morning sickness." This may not appear until the patient arises in the morning, when she feels faint, dizzy, and nauseated. Such cases are benefited by remaining in bed until a glass of milk, or a cup of warm broth with a biscuit, or a cup of cocoa or coffee and a sandwich has been taken and digested. There may then be no return of nausea during the day, but the diet should at all times be simple, especially the last meal of the day, and all richly cooked food, pastry, sweets, sauces, and elaborate "made dishes " should be avoided. Beyond this such patients may need no further treatment.

In other women the nausea is more persistent, and in the worst instances the symptom is very difficult to control by any therapeutic or dietetic measures.

Such cases are to be treated on the lines suggested above for the cure of vomiting in general and for severe seasickness. Nutrient enemata should be early resorted to if there is any sign of failing strength, and before a patient is allowed to die of inanition artificial delivery may be necessitated. Such extreme cases are fortunately very rare.

The treatment of other forms of vomiting will be considered under the headings of Alcoholism (p. 399), Acute Gastritis (p. 537), Chronic Gastritis (p. 540), and Dilatation of the Stomach (P. 546).
