The lack of body-moisture is one of the causes of supersecretion of acid, therefore water is of primary importance in removing the causes of the above disorders. It should be drunk freely immediately on rising, and just before retiring. From two to three glasses should also be drunk at each meal, especially in treating severe cases. Copious water-drinking also relieves irritation of the stomach, thus reducing abnormal appetite.

Patients afflicted with superacid-ity never have natural thirst.
