1

What is the diet?

Sum total of all foods ingested

2

Why is the GI tract central in malnutrition?

Many systems contribute to the metabolic demand but the supply falls on the gut and its associated organs

3

Over nutrition leads to

obesity which in turn leads to long term problems

4

Under nutrition leads to

weight loss and impaired function and is strongly associated with illness

5

The requirement for a nutrient is

the amount required to sustain life and prevent a deficiency

6

The demand for nutrients has a fixed component which covers;

- basal requirement e.g. membrane function
- mechanical work
- substrate turnover

7

The demand for nutrients has a variable component which covers the cost of;

- processing dietary intake
- physical activity
- maintaining body temperature
- growth

8

Give 4 symptoms of malnutrition

Malaise
Fatigue
Frequent infection/taking a long time to recover from infection
Delayed wound healing
Poor concentration
Difficulty keeping warm
Weight loss

9

Mal-digestion/malabsorption can involve;

- failure to meet nutritional requirements of the individual
- development of deficiencies
- excess of certain nutrients

10

What is malnutrition?

A state of nutrition in which a deficiency or excess of energy, protein or other nutrients causes measurable adverse effects on tissue/body form, body function and clinical outcome

11

What is the major screening tool used to detect patients at risk of malnutrition?

Malnutrition Universal Screening Tool (MUST)

12

What score on the MUST would suggest a risk of malnutrition?

> 2

13

At what score on the MUST would supplements and observation be indicated?

1

14

Give the factors associated with malnutrition

Illness
Social isolation
Age
Socially vulnerable groups

15

Give 4 clinical consequences of malnutrition

Impaired immune response
Reduced muscle strength
Impaired wound healing
Impaired psycho-social function
Impaired recovery from illness and surgery
Poorer clinical outcome

16

Undernutrition may present with;

- appetite failure
- access failure
- intestinal failure

17

If the gut is healthy and intact and the nutritional problem is due to access problems, what should be done?

Help with feeding should be given
- nasogastric tube
- PEG
