One really serious complication with type 1 diabetes is called diabetic ketoacidosis, or DKA.

1型有一种很严重的并发症，叫作酮症酸，或DKA。

We've got a diabetic ketoacidosis, let's go.

我们得了酮症酸，走吧。

Diabetic ketoacidosis can happen even in people who've already been diagnosed with diabetes and currently have some sort of insulin therapy.

被诊断出并开始接受胰岛素治疗的患者也会产生酮症酸。

And doctors have regularly smelled acetone on the breath of patients who are in a state of diabetic ketoacidosis and used it as a diagnostic.

而医生经常通过闻酮症酸患者呼吸的丙酮作为诊断方法。

Somewhat similarly, in diabetic ketoacidosis, there are low levels of insulin, and although the exact mechanism is unclear, it reduces the amount of phosphate that cells extract from the blood, causing it again to build up in the blood.

类似地，在酮症酸，胰岛素水平较低，尽管确切机制尚不清楚，它使细胞从血液提取的磷酸盐量降低，使磷酸盐再次在血液积累。
