In people without diabetes, glucose stays in a healthy range because

Normal Blood Glucose Control

Insulin is released at the right times and in the right amounts

Insulin helps glucose enter cells

American Diabetes Association

Page 4: After eating, most food is turned into glucose, the body’s main source of energy. What Happens When We Eat? American Diabetes Association

In diabetes, blood glucose builds up for several possible reasons…

High Blood Glucose (Hyperglycemia)

Too little insulin is made

Liver releases too much glucose

Cells can’t use insulin well

Type 1› Pancreas makes

too little or no insulin

Pre-diabetes

Gestational Diabetes

Type 2› Cells do not use

insulin well (insulin resistant)

› Ability for pancreas to make insulin decreases over time

Type 3??
