• Maintaining normal fluid status, or euvolaemia, is a basic requirement for health involving thirst, kidney function, hormone systems, and fluid shifts between body compartments. — Assessment and maintenance of normal fluid status in older people living in care homes: a scoping review protocol
• Normal fluid balance is regulated by the renin-angiotensin-aldosterone system and anti-diuretic hormone, which control electrolyte and fluid retention, excretion, vasoconstriction, blood pressure, and thirst. — Assessment and maintenance of normal fluid status in older people living in care homes: a scoping review protocol
• Ageing weakens the ability to maintain fluid homeostasis, causing a blunted thirst response, altered anti-diuretic hormone activity, reduced creatinine clearance, and reduced ability to concentrate urine. — Assessment and maintenance of normal fluid status in older people living in care homes: a scoping review protocol
• Age-related physiological changes increase the likelihood of both dehydration and fluid overload. — Assessment and maintenance of normal fluid status in older people living in care homes: a scoping review protocol
• Fluid is also lost through the gut, lungs, and skin in less regulated ways, adding complexity to fluid balance. — Assessment and maintenance of normal fluid status in older people living in care homes: a scoping review protocol
