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

低钠血症和低血浆渗透压合并高尿液渗透压、高尿钠，是SIADH的警示。

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，一种叫高渗性高血糖状态（HHS）的并发症在2型糖尿病中比在1型糖尿病中更常见，它会造成由极度缺水和血液浓缩引起的血浆渗透压增加。
