
Nutritional disorders
Over nutrition
 Under nutrition

Etiology of malnutrition
 Nutrition related problems

Introduction
Changes in aging  nutritional risk



 Organ system reserve
Weaken homeostasis control
 heterogenicity of response


Genetic
Environment
Geriatric failure to thrive (FTT)

FTT: state of decline


Decline in vitality…
The causes of deterioration: not identifiable or
irreversible..
Undergo a process of functional decline,
progressive apathy and loss of willingness
to eat and drink that culminate in death
4 Syndromes of FTT
Impaired physical function
 Malnutrition
 Depression
 Cognitive impairment

Manifestation





Weight loss > 5% of baseline
Appetite
Poor nutrition
Inactivity
Accompanied by



Dehydration
Depressive symptoms
Impaired immune function
Low cholesterol
Undernutrition syndrome in elderly

More common





home 2-32%
Long term care 25-60%
Institution 1-83%
Hospital 30-65%
Greater impact: less able to adapt to
underfeeding


Less frequent hunger
Not regain total # of weight
Consequences




Functional disabilities
Nosocomial infection
Perioperative complication
Morbidity, mortality
Longer LOS
Increased health care expenditure
Etiology of under nutrition
 Inadequate
 Altered

Treatment strategies
Preventing weight gain and overweight
healthy weights and
avoiding further weight gain among those
already overweight
are important public health goals.
