Role of the gastrointestinal tract in the regulation of hydration in man.
Research into the role of the gastrointestinal tract in the regulation of hydration has primarily concentrated on its function in the prevention of dehydration. The role of the gut in thirst, in the absorption of fluids and the consequences of diarrhoea are of importance in this respect. The function of the gut in the prevention of overhydration is less well understood. Intake of fluid increases excretion of water by the kidney. Inhibition of arginine vasopressin secretion, activation of renal nerves or hormonal release are possible effector mechanisms in this response.
