In these chronic febrile conditions, no special diet is required. Although light, the food must be abundant, nutritious, and varied, as in both diseases wasting and debility occur. In the apyrexial periods, solid food can be taken with impunity, but it should not be bulky or indigestible. In the later stages of kala azar, there may be intestinal ulceration or simply diarrhoea; in such cases, or even at an earlier stage, if intestinal symptoms are present, a light fluid diet, mainly of milk and barley-water, arrowroot, etc., should be adopted.
