Diabetes is a health condition that affects how your body uses sugar (glucose), which is your main source of energy. A hormone called insulin helps move sugar from your blood into your cells to be used for energy. But in diabetes, your body either:

• Doesn’t make enough insulin, or
• Can’t use the insulin properly

This causes sugar to build up in your blood instead of going into your cells, which can lead to serious health problems over time.

There are two main types of diabetes:

• Type 1 diabetes – Your body doesn’t make insulin at all.
• Type 2 diabetes – Your body doesn’t use insulin well, and sometimes doesn’t make enough.
