insulininsulin（胰島素） is a substance your body makes — mainly in the pancreas —是你身體製造出來的一種物質——主要在胰臟——that lets sugar in the blood move into cells讓血液裡的糖分可以進到細胞裡，so it can be used for energy好被拿來當作能量使用。a healthy body is releasing insulin all through the day健康的身體整天都在釋放胰島素，more after a meal when blood sugar rises在飯後血糖上升時釋放得更多。

If the body cannot make enough insulin, or cannot use it well, sugar stays in the blood; that is the problem in diabetes, which is why some people take insulin as medicine, often by injection.

if the body cannot make enough insulin, or cannot use it well如果身體無法製造足夠的胰島素，或是無法好好利用它，sugar stays in the blood糖分就會留在血液裡——that is the problem in diabetes這就是糖尿病的問題所在，which is why some people take insulin as medicine這也是為什麼有些人要把胰島素當藥物服用，often by injection通常是用注射的方式。

Though actually, many students first meet insulin as ‘the shot for diabetes’ and forget it is also something the body is already making. It is not a vitamin and not a kind of sugar; it is the messenger that helps sugar get where it needs to go.
