With regular insulin injections
How is type 2 diabetes treated
• Life style and diet changes - Increase exercise
What are type 2 diabetics less sensitive to
Insulin
Why are type 2 diabetics less sensitive to insulin
Due to a decrease in number of insulin receptors in the liver
In both types of diabetes, when will glucose concentrations rise
After a meal
What part of the body will remove some glucose
The kidneys
As the glucose is removed by kidneys where will glucose appear
In the urine
What is a glucose tolerance test used for
To test and diagnose diabetes
How to know what type of diabetes someone has after taking a glucose tolarance test
Type 1 - remains high Type 2 - delay of insulin response
How does a glucose tolerance test work
• blood glucose concentrations measured after a period of fasting • then a glucose solution is consumed • then changes in blood glucose concentrations are measured for at least 2 hours
What happens in a glucose tolerance test for a diabetic
• Blood glucose concentration will start higher and increase to a much higher level than that of a non-diabetic • and takes much longer to return to normal
