體液容積過量代表體內水分過多，導致血液被稀釋。因此，檢驗結果通常會反映出血液被稀釋的情況。
Fluid volume overload refers to an excess of fluid in the body, leading to the dilution of blood. As a result, laboratory tests often reflect a diluted blood state.
血比容下降：
Hematocrit decreases:
體液過多導致血液總量增加，但紅血球數量並沒有明顯增加，因此血比容下降。
An increase in total blood volume due to excessive fluid, while the number of red blood cells remains relatively unchanged, results in a decrease in hematocrit.
血尿素氮下降：
Blood urea nitrogen (BUN) decreases:
當體液過量時，血液被稀釋，尿素的濃度就會下降。
When there is fluid overload, blood is diluted, leading to a decrease in urea concentration.
血漿滲透壓上升和血鈉上升則通常發生在脫水或鈉過量的情況下，當體內水分不足或鈉離子過多時，血液濃度會升高，導致血漿滲透壓和血鈉上升。
Plasma osmolality and sodium levels increase in cases of dehydration or sodium excess. When the body is dehydrated or has excessive sodium, blood concentration increases, leading to an increase in plasma osmolality and sodium levels.
治療體液容積過量的方法主要包括：
Treatments for fluid overload primarily include:
限制鈉鹽攝入： 減少鈉鹽攝入可以減少水分瀦留。
使用利尿劑： 利尿劑可以促進鈉和水分的排出。
治療原發疾病： 針對引起體液容積過量的原因進行治療，例如治療心力衰竭、腎臟病等。
Restricting sodium intake: Reducing sodium intake can decrease fluid retention.
Using diuretics: Diuretics can promote the excretion of sodium and water.
Treating the underlying cause: Treating the underlying cause of fluid overload, such as heart failure or kidney disease.
