AGING Aging is not a homogenous process.
Organs in the same person age at different rates influenced by
Genetic-make up Lifestyle choices Environmental choices

AGING AND GASTRO INTESTINAL SYSTEMWhat does it affect?
Swallowing and chewing aspiration Decline in taste and smell Increased rates of gastritis and increased
sensitivity to medication Changes in intestine structure; less effective
uptake of micronutrients (Vit B12) Less vitamin D receptors lower efficiency of
calcium absorption. Reduced propulsive motility obstipation Reduced anal sphincter tone fecal incontinence

MALNUTRITION
Risk of
malnutrition
Loss of appetite----------
Lower Energy requirement
Decline in Energy intake
Increase in fat massDecline in muscle mass
↓ Exercise

WHO IS AT RISK OF MALNUTRITION? Elderly Chronic disease
Cancer COPD Heart failure Kidney failure

WHAT ARE THE CONSEQUENCES OF MALNUTRITION?
![Page 12: The process of aging](https://reader036.vdocuments.net/reader036/viewer/2022062501/568166ef550346895ddb48d4/html5/thumbnails/12.jpg)
HOW LARGE IS THIS GROUP? < 1500 Kcal/day ; High risk of micronutrient
deficiency.
20 % of people > 75 year who living independently
40% of elderly living in a nursing home

HOW DO RECOGNIZE SOMEONE AT RISK? By weighing!
Weight loss: > 5% in 1 month (3 kg/month) > 10% in 6 months (6 kg/month)(independent of the initial weight)
< 65 year: BMI < 18,5 kg/m2 > 65 year: BMI < 20,0 kg/m2

MAJOR BOTTLENECKSVitamin D deficiency! (sunlight)
Water Proteins Vitamin A Vitamin B6, Folic acid, Vitamin B12 (due to
malabsorption) Vitamin C Calcium (diuretics) Iron Iodine
