People living with renal failure have to endure a demanding treatment regimen to keep them alive including haemodialysis, a restricted diet and fluid intake and multiple drug treatments. These demands have a profound effect on the patient's quality of life. It is not surprising that many find it very difficult to manage some treatments even when they are known to be important for the patient's survival. Restricting fluid intake (often as little as 500ml per/day) is an essential treatment for many patients with advanced kidney failure receiving haemodialysis, but many find it difficult to adhere. Estimates of fluid restriction non-adherence range between 10-70%. Not adhering to the recommended maximum fluid intake leads to fluid overload, which is associated with pulmonary oedema, cardiovascular disease and premature death.
