Because their bodies produce no insulin, people with Type I diabetes must obtain it through injection. Their bodies produce some insulin, but it is not enough or it doesn t work properly to funnel glucose through the receptors into their cells.

Type II diabetes can sometimes be controlled with a carefully planned diet and exercise, but oral medications or insulin injections may be necessary.

As people age, their bodies may have fewer insulin-producing beta cells.
