In casual Korean conversation, the phrase 당이 떨어진다 (my sugar is dropping) is often used by non-diabetics to describe a sudden lack of energy or moodiness.
Because 당뇨병 is a Sino-Korean word, it is identical in writing to the terms used for diabetes in Chinese and Japanese.
The word 당뇨병 is a Sino-Korean compound where 당 (sugar), 뇨 (urine), and 병 (disease) are combined to literally describe the physiological symptom of 'sugar in the urine'.
