Flashcards in Osteoporosis Deck (18):
1

Major Osteoporosis factors

Osteoporosis dx
Decrease in height, rounding/humpback
Trauma fx
Family hx
Menopause/hysterectomy before 45 or amenorrhea
HRT
Caucasion, asian
Long-term restricted diet or yoyo dieting
Smoking!
Not enough sun!
Not enough strength exercises!

2

Minor osteoporosis risk factors

Salt intake (urinary calcium)
Smoking less than a pack a day
Drinking
High animal protein intake
Packaged convenience food intake
Carbonated soft drink intake
High fiber intake (phytate)
Low soy
Lots of coffee
Lots of stress
Lots of antacids
No birth control
No pregnancies
Vitamin A too much

3

Medical conditions or medications that increase osteoporosis risk

Corticosteroid, anti-convulsant, anti-coagulant, aluminum containing antacids, acid blockers, aromatase inhibitors, non-thiazide diuretic meds
Gastric sx or malabsorptive dz
RA, DM, Hyperthyroidism, cushings, endocrine disorders, alcoholism, kidney dz

4

Who should receive bone mineral density testing?

Women > 65, men 65, major risk favtors + menopause
Women and men

5

Good diet for reduction of osteoporosis

Adequate calories and protein
Low sodium and caffeine
Low salt, protein, high calcium (milk, yogurt, hard cheese, tofu made w/ calcium, chinese cabbage or greens, bok choy, kale)
Alkaline ash diet
Strength exercise
Avoid smoking and excessive alcohol
DON'T YOYO DIET

6

3 reasons lots of soda = increase osteoporosis risk

High sodium, caffeine, phosphoric acid

7

Better dairy products

Low in salt and protein, high in calcium = milk/yogurt

8

Poor choices for dairy products

High in salt and protein, low calcium = cottage cheese, american cheese

9

Calcium carbonate

Most concentrated andmost cost effective! Must take with meals for good absorption.
EG. OSCAL

10

Calcium citrate

Patienst with kidney stone risk. Take with meals
EG. CITRICAL

11

Calcium citrate-malate and microcrystalline hydroxyapatite

Diagnosed osteoporosis and fractures

12

Vitamin D does whatc

Calcium absorption
Improves neuromuscular function
Reduces falls
Deficiency = muscle weakness
+ calcium = increased bone density, prevents fractures in postmenopausal women and elderly men

13

What should you take with vitamin D to inpmrove effectiveness?

Calcium!

14

Besides calcium, what else helps to reduce bone loss?

K, Copper, Magnesium, manganese, zinc!
KCMMZ

15

Ipriflavone, why controversial?

Synthetic isoflavone
Revereses bone loss + calcium
Only use for very bad osteoporosis patients
Reported low WBC as side effect

16

vitamin K in bone formation?
What metabolite in blood = indicator of inadequate vitamin K status?

Decreases urinary calcium loss in postmenopausal women.
Under-carboxylated osteoclaci in blodo = increased fracture risk

17

K1

Reduces undercarboxylated osteocalcin, improves bone density
Reduces bone loss
5000 mcg/day reduced risk by more than 50%

18

K2

Megadose therapy study in japan = increased bone density, reduced fracture risk
