Type 1 Diabetes is caused when the pancreas produces little to no insulin. This keeps glucose from entering the cells which can be life threatening without treatment.
The body is effected on a cellular level, because there is no Insulin being produced to allow glucose into the body's cells. In turn, the whole body would begin to malfunction due to this.
Type one diabetes is most commonly treated by administering insulin every day as needed. However, special diets and exercise are also used to treat this disease.
Diabetes was first recorded in English, in the form diabete, in a medical text written around 1425. However, treatment for this disease was not found until 1922 by Banting, Best, and their chemist colleague Collip .
