disease of body’s inability to sufficiently metabolize glucose

41
Q

what is polyphagia

A

increased appetite

42
Q

what is polydipsia

A

increased thirst

43
Q

what is polyuria

A

excessive urine

44
Q

how does diabetes affect kidneys

A

principal cause of kidney failure because it causes kidneys to work harder

45
Q

what is microangiopathy

A

deterioration of vessel walls

46
Q

why does diabetes increase chance of heart disease

A

lipolysis increases level of fat in blood and adheres to vessel walls

47
Q

what contributes to increased risk of silent MI in diabetes patients

A

microangiopathy and neuropathy

48
Q

what is neuropathy

A

nerve damage that results in loss of sensation

49

A

type 1

50
Q

what is latent autoimmune diabetes

A

variant of type 1 diabetes that occurs in adults older than 30y/o

51
Q

what happens in type 2 diabetes

A

“insulin resistance” body can’t produce enough insulin to compensate for inability to use insulin effectively

52
Q

type 1 diabetes is insulin ____
type 2 diabetes is insulin ____

A

dependent
resistant

53
Q

what is metformin prescribed for

type 2 diabetes

56
Q

hypoglycemia is less than ___mg/dL

A

45

57
Q

3 lines of defense for hypoglycemia

3rd: ANS stimulation for counter-regulatory hormones

58
Q

what is the dawn phenomenon

A

body releasing cortisol and catecholamines in the morning before waking triggers release of glucose from the liver

A

weight gain “moon face” or “buffalo hump”, darkening of neck skin, high BGL, increased thirst/urination

73
Q

what is pheochromocytoma

A

tumor in the medulla of adrenal gland causes excessive release of epi and norepi

74
Q

what is acromegaly

A

over secretion of GH from anterior pituitary gland (usually from tumor) that causes gigantism

75
Q

what is dwarfism

A

under secretion of GH from anterior pituitary gland causing delayed development and growth

76

A

hypertrophied thyroid from Graves disease

77
Q

what is exophthalmos and what disease is it linked to

A

edema of tissue behind eyes - Graves

78

hypercalcemia and decreased phosphate levels

83
Q

what is panhypopituitarism

A

inadequate production or absence of pituitary hormones

84
Q

what is diabetes insipidus

A

body can’t regulate fluid due to lack of ADH or kidneys are unable to respond appropriately

85
Q

difference between diabetes insipidus and SIADH

A

diabetes insipidus: decreased levels of ADH, polyuria, dehydration

SIADH: increased ADH levels, oliguria, systemic fluid overload

86
