Term
What is the normal blood glucose a person should maintain?
Definition
8-120 mg/dl
Term
What are the 4 tissues that require a continuous source of glucose?
Definition
brain, RBC, medulla of kidney, intestinal eipthelium
Term
T/F Water is lost when there is an excess of sugar taken in?
Definition
True...so you will then store it in the liver as glycogen by insulin (it may also be stored in fibroblasts, fat cells or muscle)
Term
What are the 6 characteristics of diabetics when the blood glucose goes up unopposed?
Definition
1. polyuria
2. polydypsia
3. polyphagia
4. lose weight
5. Eat more
6. Becomes weak because glucose can not get into muscles as glycogen
Term
T/F If glucose is too low then your body takes it from storage via glucagon?
Definition
F...via glucagon and epinephrine from liver; glucagon and growth hormone from adipose and cortisol and glucagon from proteins
Term
T/F High levels of glucose in blood favors growth of microorganisms?
Definition
True
Term
What is the fat problem associated with diabetes described by Bernstein?
Definition
Without sugar entering adipose and being unavailable as energy source so then broken down fat enters into Kreb cycle as acetyl coA whic then can cause hypercholesterolemia, hyperlipidemia and ketosis
Term
T/F Poor healing and greater risk of infection occurs as a result of protein problems of diabetes?
Definition
True
Term
For the areas of the body that don't need glucose, what is the alternative pathway used?
Definition
Polyol pathway
Term
T/F Peripheral neuropathy can occur as a result of sorbitol accumulation from the kreb cycle?
Definition
F...all if true except it occurs from the polyol pathway
Term
T/F Everyone has HbA1C?
Definition
True....just in small amounts
Term
Why does microangiopathy occur?
Definition
1. Genetic/Weakened endothelium
2. Sorbitol pathway
3. Just having high blood glucose
Term
What happens with there are high blood glucose levels?
Definition
glucose combines with proteins and "glycosylates" them.... which then deposit into blood vessels
Term
What are the effects of microangiopathy?
Definition
Kidneys: nodular glomerulosclerosis
Retina: blindness and glaucoma
Skin: rahses
Term
T/F Type II diabetes is characterized by sudden failure of insulin?

What are the 5 main causes to get type I diabetes?
Definition
Main: Genetic propensity and a trigger
Minor (could be trigger): susceptible HLA profile, viral infection, develop autoimmune dx

Definition
False...type II is 90% of cases...type I is only 10%
Term
T/F Type II diabetic has insulin?

True
Term
Type II diabetics do not get ketosis like Type I but what are 7 other things that they could get?
Definition
1. Lots of infections
2. Poor healing
3. Severe coronary atherolsclerosis
4. Unexplained candidiasis
5. vision problems
6. Peripheral neuropathies
7. Kidney dx
Term
Since Type II diabetics have insulin what is the reason they have diabetes?
Definition
THey have insulin resistance due to not having enough receptors...#1 environmental factor is obesity while pregnancy, stress and infections can contribute
Term
What are the 7 target organs that are changed in diabetics?
Definition
1. heart--> atherosclerosis
2. Brain
3. kidneys --> nodular glomerularsclerosis and necrotizing papillitis
4. blood vessels--> poor healing (legs "fall off")
5. eyes --> glaucoma, blindness
6. peripheral nerves (sorbitol)
7. skin --> xantholasmas, loss of gingival height, rapid bone loss and perio dx, uncontrolled candidiasis
sometimes pancreas
Term
What are the 4 types of diabetics and COMA?
Definition
Insulin shock --> type I and brittle
Diabetic shock --> type I not taking insulin
Hyperosmolar COMA --> poorly controlled type II
Lactic acidosis --> General poor vascular perfusion
Term
What are the 4 types of diabetes according to the ADA?
Definition
Type 1, Type 2, Gestational and Secondary
Term
T/F Type 2 diabetics are prone to ketosis?
Definition
False...that is type 1
Term
T/F In type 1 diabetes a prodromal phase of polyuria, polydypsia and weight loss may precede the development of ketoacidosis by a period of days or months?
Definition
True
Term
Is the genetic predisposition stronger with type 1 diabetes or type 2 diabetes?
Definition
Type 2
Term
T/F Ongoing, autoimmune destruction of pancreatic beta cells may underlie type 1 diabetes?
Definition
true
Term
What are the 4 main diagnostic features of type 2 diabetes?
Definition
1. Most patients are >40 y.o. and obese
2. Polyuria and polydypsia. Ketonuria and weight loss are usually uncommon at time of diagnosis. Candidal vaginitis in women. While some have no symptoms
3. Plasma glucose of 126 mg/dL or higher after an overnight fast on more than one occasion. After 75 gms oral glucose, diagnostic values are 200 mg/dL or more 2 hrs after the oral glucose and at least once between 0 and 2 hours
4. Hypertension, hyperlipidemia, and atherosclerosis
Term
What is the more important cause of insulin resistance in type 2 diabetes?
Definition
the failure of postreceptor coupling and of intracellular insulin action
Term
What syndrome of insulin resistance has been proposed to explain the frequent association of hypertension, carb intolerance, abdominal obesity, hyperlipidemia and accelerated atherosclerosis of type 2 diabetes?
Definition
Syndrome X
Term
Mild to marked obesity is present in approximately what percentage of type 2 diabetics?
Definition
