Low blood sodium levels and low plasma osmolarity combined with high urine osmolality and high urine sodium is a giant red flag for SIADH.

低血症和低血浆压合并液压、，是SIADH的警示。

Another important mechanism is hyperosmolarity, which is where there is an increased extracellular osmolarity, relative to the intracellular space.

另一个重要机制是压，即相于细胞内，细胞外压增。

The kidneys regulate osmolarity because they have direct control over how many ions and how much water a person excretes.

肾脏调压，因为它们直接控制一个人排出多少离子和多少水。

Having said that, a complication called hyperosmolar hyperglycemic state (or HHS) is much more common in type 2 diabetes than type 1 diabetes - and it causes increased plasma osmolarity due to extreme dehydration and concentration of the blood.

虽说如此，一种叫性血糖状态（HHS）的并发症在2型糖病中比在1型糖病中更常见，它会造成由极度缺水和血液浓缩引起的血浆压增加。
