Diabetes Mellitus Flashcards
Type 1 DM
insulin dependent: pancreas doesn’t produce insulin
- diagnosed mostly as child
- symptoms: polydipsia, polyuria, polyphagia
-weightloss>10lbs
-ketoacidosis (body burns fat as fuel which starts making acids=ketone bodies=life threatening
- blurred vision
- dehydration
polyuria
increased urination
polydipsia
increased thirst
polyphagia
increased hunger
type 2 DM
- insulin resistant: body keeps making insulin but body’s tissues stop accepting insulin, which is why blood glucose increases
- secondary to other dysfunction: due to hypertension, inactivity, obesity
- symptoms similar to type 1 without ketoacidosis: polydipsia, polyuria, polyphagia
DM diagnosis criteria
fasting blood glucose: >126 mg/dL
resting blood glucose: >200 mg/dL
HbA1C: >10% (requires immediate insulin therapy
(normal is 4-6%)
- most accurate, taken over 3 months
hyperglycemia
BG >300dg/mL
early signs:
- hot and dry sugar, 3 Ps
- dry mouth
- frequent/scant urination
- extreme thirst
- kussmaul breathing (deep, and shallow)
- weakess
- decreased senses, diminished reflexes, confusion
late signs:
- fruity odor (acetone) breath
- hyperglycemic coma
hypoglycemia
BG <70dg/mL
cold and clammy, give a candy!
early signs:
- pallor, sweating
- shakiness
- unsteady gait, dizziness, decreased coordination
- extreme hunger
- fainting
-tachycardia, heart palpitations
late signs:
- confusion, drowsiness, slurred speech
- LOC, coma
relationship between blood glucose and insulin
-BG is high when tissues dont let in insulin
-when tissues let in insulin, BG decreases
what can exercise result in for patients with type 2 diabetes - recommendations to avoid this
hypoglycemia - because exercise increases insulin sensitivity and lets more insulin into tissues. This leads to decreased blood glucose
recs:
- avoid exercise during peak insulin hours (2-4hrs after taken) (because insulin is at peak so BG will drop even further)
- apply insulin in abdomen/non-active extremity because insulin is absorbed much more quickly in active extremity
- insulin dosage should be decreased after exercise
exercise recs for type 1 and 2 DM
-exercise in morning to avoid insulin fluctuations which happen more at night
-Do not exercise in extreme hot or cold
-Pt should be well hydrated
Random BG levels relating to exercise
100-250mg/dl: safest
250-300mg/dl: proceed with caution
70-100mg/dl: give 15g of carb, wait 15min, proceed if ok
<70: contra, give candy or juice
>300: contra, send to MD (not emergency)
ketone bodies (fruity odor): contra
diabetic foot care
- cut toenails
- skin checks regularly
- do not soak feet, just wash/rinse
- white socks so you can see bleeding
- do not moisturize between toes
- alternate which shoes you wear
- buy shoes in evening because feet swell
-snug shoes to avoid blisters
FITT for DM
frequency
3-7 days/wk (more freq is bettter)
FITT for DM
intensity
11-13 on RPE scale (can go up to 17
