dawn phenomenon
fasting hyperglycemia without prior nocturnal hypoglycemia..
happens when growth hormone is secreted at night and patients awake with elevated fasting glucose. dawn phenom. is exaggerated in pregnancy due to additional hormones secreted at night.
inject NPH insulin at bedtime to treat; it will peak as the level of growth hormone rises.
diabetes mellitus (DM)
group of metabolic disorders characterized by abnormal fuel metabolism, all of which have hyperglycemia in common. these disorders result from defects in insulin secretion, insulin action, or both.
diabetic ketoacidosis (DKA)
life threatening complication from acute or relative deficiency in insulin secretion and characterized by profound disturbances in metabolism of carbs, fat, proteins.
typically treated in ICU. patient care aimed at correcting severe dehydration, insulin deficiency, metabolic acidosis from ketosis and lactic acidosis, and depletion of electrolytes from osmotic diuresis.
precipitating event must also be identified and corrected.
fruity breath
commonly happens with Type 1 diabetics, but can happen with Type 2 also
diabetic peripheral neuropathy
polyneuropathy in legs, feet, hands. potentially very serious complication of diabetes. significant factor in pathway leading to lower extremity ulcers. predominantly associated with sensory loss, but motor and autonomic nerve fibers can also be affected.
s/s: numb, pain, burning, tingling, eventual partial or total loss of sensation over weeks or months. pain felt first distally, usually in lower legs and worse at night. pain can be persistent or intermittent. primary tx: pain management
gestational diabetes mellitus (GDM)
onset of diabetes in pregnancy.
2-10% prevalence, can reach 10-20% in high risk populations.
risk factors: previous GDM, advanced maternal age, obesity, family hx of DM, racial/ethnic (african americans, hispanics, latinos, american indians have highest risk).
require dietary treatment, possibly oral meds or insulin therapy to control hyperglycemia.
uncontrolled hyperglycemia in pregnancy can cause fetal/maternal complications
GDM resolves after birth, however these women have 35-60% chance of developing DM in the 10-20 yrs after.
glucosuria
the presence in the urine of abnormal amounts of sugar.
hemoglobin A1c (HgA1c)
the Hgb A1c test is the primary lab test for monitoring long term glucose control.
A1c is formed when glucose in the blood binds irreversibly to hemoglobin to form stable glycated hemoglobin complexes. protein glycation is the nonenzymatic reaction of sugars with proteins. norm RBC life is 90-120 days. so A1c reflects the average blood glucose values of previous 2-3 months and is directly proportional to concentration of plasma glucose in blood over life span of red blood cells.
hyperglycemia
high blood glucose
hypoglycemia
low blood glucose
hypoglycemic unawareness
loss of autonomic nervous system response to low blood glucose. symptoms like tachycardia, sweating, palpitations that normally prompt patients to eat are no longer there. results from altered counterregulation, esp deficient glucagon and epinephrine responses to hypoglycemia.
at risk for severe hypoglycemia and injury; probability of unawareness should be considered in pts with increased emphasis on normalization of BG control using intensive insulin regimens and oral hypoglycemic combo therapy
