The symptoms in Addison's disease are mainly of a general kind, the result of the altered nutrition which the loss of the suprarenal function entails, and local disturbances are secondary to the general asthenia.

In the earlier stages abdominal symptoms are rarely experienced, though anorexia may be extreme and persistent; but later on both gastric and intestinal symptoms may be severe, and they are not infrequently the immediate cause of the fatal issue. They often occur in a paroxysmal manner, and may be excited by apparently trivial causes.

Nausea and vomiting may thus be violent and repeated, and interfere greatly with the taking of food; while diarrhoea is apt to occur spontaneously and may follow the use of laxative medicines, or the ingestion of indigestible articles of food.

Care should therefore be taken to prevent the possibility of such disturbances.

The treatment of gastric or intestinal symptoms must be conducted on general lines, and has already been considered in sufficient detail.
