List 3 ways alcohol may increase the risk of malnutrition in an alcoholic patient.
Reduced food intake: Replacement + Altered appetite + Change behaviour (risky)
Digestion: Reduced secretion of pancreatic enzymes + bile
Absorption: Damaged mucosal lining + inhibited by nutritional deficiencies e.g. folate
Nutrient transport + assimilation: Reduced liver stores of vitamin A + increased excretion (fat stores)
Secondary malnutrition: Chronic pancreatitis + liver disease; infection and injury; ascites reduces appetite; REE increased in alcoholic hepatitis
Why might sarcopenia occur in a patient with liver disease?
Lipid oxidation + reduced protein synthesis ≈ muscle atrophy ≈ susceptible to complications (ascites, infections, falls etc)

Malnutrition Universal Screening Tool (MUST) is a validated screening tool comprising of 5 steps which is scored from 0-6.
1) BMI Calculation
> 20 = 0
18.5-20 = 1
< 18.5 = 2
2) Unwanted weight loss in 3-6 months
5% = 0
5-10% = 1
> 10% = 2
3) Disease state
Acutely ill > 5 days = 2
4) Calculate Score
5) Stratification
0 = low risk
1 = medium risk
2 = high risk
A patient comes and requires a MUST score generated. They are 184cm and weigh 80kg. In the last 4 month they have lost 5kg however they were on a weight-loss regime. In the last 4 days they have been acutely ill with D+V.
What is their score?
BMI > 20 = 0
Weight loss ≈ 6% however intended so scores 0
Acutely ill = 2
MUST score = 2
