1. Avoidance of trigger factors for vasomotor
symptoms:
Alcohol
caffeine,
smoking,
hot or spicy food or drinks,
hot environment &
stress.
Good ventilation, minimal heating & light bed
linen.

2. Avoidance of risk factors associated with
osteoporosis:
Smoking, alcohol & inactivity.
Smoking is associated with reduced bone formation
due to:
1. the toxic effect of nicotine on osteoblasts or
2. the increased hepatic clearance of oestrogen,
which in turn will increase bone resorption.
Alcohol:
higher risk for breast cancer with even moderate
intake (Stampfer et al, 2005)
ABOUBAKR ELNASHAR
Plan for to quit smoking (Malat,2005):
Pick a quit date,
visualize yourself as a nonsmoker;
seek out support from friends and family;
recognize the triggers and find substitutes; and
consider using medication, such as the nicotine patch
and bupropion.
The most successful method of overcoming the
smoking habit is a combination of both behavior-
modification therapy and prescription drug treatment.

Excercise: Effects:
1. In early life maximize bone mass & later
help to conserve it.
2. Extremely important to cardiac health,
helping to reduce weight, blood pressure &
cholesterol levels. Women who walked for
1h/w experienced half the CHD risk of women
who did not walked.
3. Reduced incidence of severe hot flushes,
depression & improve mood.
ABOUBAKR ELNASHAR
Type:
Regular
Weight bearing.
The safest excercise is walking
30 minute 4-5 times /w.

A balanced diet should comprise whole grains,
fruits, vegetables, minerals and vitamins, with
a minimal amount of saturated fats.
Calcium with vitamin D supplementation is
recommended
I. Multivitamins.
II. Minerals.
III. Natural hormones.
ABOUBAKR ELNASHAR
I. Multivitamins
1. Vit E: 400-1200 IU daily
a. Reduces VM symptoms (Kass-
Annesse,2000)
b. Reduces the risk of CHD (100 IU daily for
2 years) {The Nurses health study, 1993).
Low level of Vit E is a better predictor of CHD
than elevated cholesterol or blood pressure (Cooper et al,1994)
ABOUBAKR ELNASHAR
2. Vitamin D: 400 IU daily with calcium
significantly reduced fracture risk (Chapuy et al, 1992)
Oily fish eaten at least twice a week reduced
mortality from CHD (Daviglus et al, 1997)
Garlic: reduction of cholesterol is doubtful (Daviglus et al, 1997)

II. Minerals:
•Adequate calcium intake: 1500 mg daily:
reduction of hip fracture (Cumming et al, 1997).
•Adequate intake of magnesium is crucial for
osteoporosis prevention (Kass-Annesse,2000).
The dietary ratio of calcium to magnesium is
best maintained at 2:1.
ABOUBAKR ELNASHAR
•Avoid factors increasing urinary
calcium loss . High sodium intake
. High phosphorus (soft drinks such as cola) & may
be damaging for young bone
(Carey & Carey, 1999). . High protein intake, generally in the form of animal
protein (Nordin, 2000).
. High caffeine intake is associated with an increase
in fracture

III. Natural hormones 1. Phytoestrogens
Asian women experience fewer menopausal
symptoms than western women & their traditional
diet contain high level of phytoestrogens, about 200
mg daily compared with < 5 mg daily in western diet.

substance in a highly diluted solution may treat the
disease.
