identify classification of DM:
Associated with autoimmune disease
Type 1
identify classification of DM:
Usually develops in children and young adult
Type 1
identify classification of DM:
Associated with a faster onset of symptoms, leading to dependency on extrinsic insulin for survival

identify classification of DM:
Occurs in adults older than 40 years
Type 2
identify classification of DM:
Peaks onset between 60 and 70
years
Type 2
identify classification of DM:
Caused by a relative insulin deficiency and the body’s inability to effectively use insulin

identify classification of DM:
Symptoms are slower in onset and less marked than the other type of DM
Type 2
identify classification of DM:
Hyperglycemia that is first detected during pregnancy, usually diagnosed during the 2nd or 3rd trimester

associated with adverse outcomes, including hypertension or pre-eclampsia, fetal macrosomia or fetal death
Gestational diabetes
Gestational diabetes is usually diagnosed during the _____ or _____ trimester
2nd or 3rd
hypertension during pregnancy
pre-eclampsia
condition wherein the weight of the newborn is way heavier than average (4.4pounds or 2kg is the normal wt.; infants with this condition weigh about 9pounds)
fetal macrosomia
identify classification of DM:
Diabetes is a result of a pre-existing condition
Specific Type due to other causes
Specific Type due to other causes may be due to (give 2)

cortisol is a hormone that can (increase/decrease) blood glucose
increase
