Mucous gastritis must be regarded as a complication of one of the two preceding forms. The diet adapted to individual cases will depend upon the functional activity of the stomach.

In general, however, it can be said that when the stomach contains large amounts of mucus, the utmost pains should be taken to insure cleanness of the viscus. Lavage must be practised, and will contribute greatly to the relief of the patient. It is best to wash the stomach with an alkaline solution, as sodium bicarbonate, one dram to the pint of hot water. Food should be given in small amounts at a time, and preferably in liquid or powdered form or with powder in suspension in liquid. As to the kinds of food, one must be governed by the activity of the organ - that is, its power to form gastric juice and to do muscular work.
