17
Q

What measurements are good indicators of b-cell function and insulin levels?

A

serum and urine c-peptide measurements

18
Q

What percentage of those with diabetes have type 1 diabetes?

A

5-10%

19
Q

What is another name for type I diabetes?

A

Insulin-dependent diabetes (requires exogenous insulin)

20
Q

What happens to a person’s body who has type I diabetes?

A

body cells will develop antibodies against insulin and/or pancreatic beta cells that produce the insulin

21
Q

What is latent autoimmune diabetes in adults?

A

slow, progressive type 1 diabetes

22
Q

What can be a result of type I diabetes if it is unknown and there is a rapid onset?

A

DKA

23
Q

A patient comes in complaining of frequent urination, extreme thirst, insatiable hunger accompanied with unintentional weight loss, what may this patient be experiencing?

A

manifestations of Type I diabetes

24
Q

What percentage of those with diabetes have type II diabetes?

A

90-95%

25
Q

What are a few risk factors for type II diabetes?

A

overweight or obese, advanced age, family history

26
Q

Why would someone develop type II diabetes?

A

Pancreas continues to produce some endogenous insulin but
Not enough insulin is produced and/or
Body does not use insulin effectively

27
Q

5 ways that type II diabetes may occur

A

Insulin resistance
2.Decreased insulin production by pancreas
3.Inappropriate hepatic glucose production
4.Altered production of hormones and cytokines by adipose tissue (adipokines)
5.Research continues on role of brain, kidneys, and gut in type 2 diabetes

A

patients that are obese, ama, or have a family history of diabetes

33
Q
