7

what is the worry with gestational diabetes mellitus?

- that it may progress into type 2 even after birth

8

4 facts about type 1 diabetes mellitus

1. auto immune condition (destruction of the islet cells)
2. affects younger patients
3. insulin dependant
4. genetic element

9

2 facts about type 2 diabetes mellitus

- unusual to be diagnosed under 40
- insulin resistant

10

what are the two ways that insulin can be administered to those with type 1 diabetes mellitus?

1. injection
