So another ingredient could potentially be responsible here.

是以，另一種成分有可能是這裡的原因。

However, if you're drinking a full cup of coffee, there's fluids in there, so it replaces the fluids you lose, right?

然而，如果你喝了一整杯咖啡。裡面有液體。 所以它可以補充你失去的液體，對嗎？ 

However, if you're drinking little espressos or espresso shots in your coffee, and you're getting a ton of caffeine in there, you're not replacing the loss fluid, and then in that case, it can be somewhat dehydrated.

然而，如果你喝的是小杯濃縮咖啡或者在咖啡中加入濃縮咖啡粉。 而且你在那裡得到了大量的咖啡因。 你不是在更換損失的液體。 然後在這種情況下，它可能會有些脫水。

The second is through the disruption of the metabolism of the medications through enzymes.

第二種是通過擾亂新陳代謝的藥物通過酶的作用。 

For example, the blood levels of clozapine, lithium, warfarin, and several antidepressant drugs actually were increased after the ingestion of coffee, making them more potent and potentially increasing toxicity.
