Q

Why does type 1 diabetes need careful monitoring?

A

If a person injects themselves with too much insulin, they may experience hypoglycaemia, that can result in unconsciousness, however too low insulin doses results in hyperglycaemia, which can result in unconsciousness and eventual death

How is type 2 diabetes treated?

Through changing the patients diet and exercise levels.
However if this is not enough to control blood glucose levels, drugs stimulating insulin production or insulin injecting may be administered

Q

In people with type 1 diabetes, what is the effect of a spike in blood glucose levels on insulin levels?

Q

What is the difference between the blood glucose levels of non-diabetics and diabetics following a spike in glucose levels?

A

In non-diabetics, insulin is produced in response, causing glucose levels to rapidly decrease.
In diabetics, insulin is not produced, meaning glucose levels return to normally much more slowly, as it is gradually used by cells
