What is cholelithiasis?
Hard deposits/stones developing in gallbladder if bile has high levels of cholesterol/bilirubin or low levels of bile salts; gallbladder dysfunction or release of bile impaired
What are the two main types of gallstones and how are they categorised?
1) Pigment (bilirubin) stones: Gallstones made of bilirubin
2) Cholesterol stones: Gallstones made of cholesterol

List the lifestyle + nutrition advice is there for prevention and reduction of gallstones.
Good diet: Regular meals/Micronutrient intake/ Fruits and vegetables
Physical activity: Glucose utilisation/HDL:LDL ratio/HDL increase
Maintain body weight: Stable weight/Progressive weight loss/Weight diet/High BMI/Rapid weight loss
Outline 3 dietary habits which can help prevent gallstones.
1) Regular eating patterns
- Increase gallbladder emptying
2) Fibre + Calcium
- Reduce biliary hydrophobic bile acids
3) PUFA/MUFA (and nuts)
- May protect
4) Fruit and Vegetables
- May protect
5) Micronutrients: Vitamin C + Calcium
- Conversion of cholesterol to bile acids
Outline the stages of Liver disease.
Hepatitis: Inflammation
Fibrosis (scarring)
Cirrhosis (spread + fibrosis)
Hepatocellular carcinoma
List 3 common causes of Liver Disease.
Viral Hepatitis (B+C; A+E)
Chronic alcoholism
Obesity
Dyslipidemia
Genetics: LDL-/-; ApoE-/-
Outline the lifestyle changes which can be made in NAFLD.
Reduce dietary intake 500-1000kcal/day
Micronutrient composition of diet: Vitamin A, B, C, D, E etc
Physical Activity: 150CME with x2 resistance
Drinks: Caffeine
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)
How can you detect malnutrition in liver disease?
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
A patient comes and requires a MUST score generated. They are 173cm and weigh 90kg. In the last 4 month they have lost 5kg however they were on a weight-loss regime. In the last 2 days they have been acutely ill with D+V.
What is their score?
BMI > 20 = 0
Weight loss ≈ 5% however intended so scores 0
Acutely ill = 2
MUST score = 2
A patient comes and requires a MUST score generated. They are 173cm and weigh 90kg. In the last 4 month they have lost 5kg. In the last 2 days they have been acutely ill with D+V.
What is their score?
BMI > 20 = 0
Weight loss ≈ 5% thus scores 1
Acutely ill = 2
MUST score = 3
List 3 common potential deficiencies in Alcoholic Liver Disease.
1) Vitamin B1 (Thiamine): Poor intake, Reduced conversion to co-enzyme, Reduced storage in fatty liver; Inhibited intestinal absorption; Increased metabolic demand (used in ethanol metabolism)
2) Folate and B12: Metabolism impaired ≈ megaloblastic anaemia
3) Niacin: Poor intake, Reduced conversion to co-enzyme, Reduced storage in fatty liver; Inhibited intestinal absorption
- Pellagra
4) Vitamin C: Poor intake, Reduced conversion to co-enzyme, Reduced storage in fatty liver; Inhibited intestinal absorption
- Scurvy
5) Vitamin A: Poor intake, Reduced conversion to co-enzyme, Reduced storage in fatty liver; Inhibited intestinal absorption
- Night blindness due to reduced levels of plasma retinol
6) Vitamin D: Poor intake, Reduced conversion to co-enzyme, Reduced storage in fatty liver; Inhibited intestinal absorption
- Rickets/Osteomalacia
- Osteoporosis
7) Calcium: Increased urinary excretion + Poor intake, Reduced conversion to co-enzyme, Reduced storage in fatty liver; Inhibited intestinal absorption
- Osteoporosis
- Hypocalcemia
8) Zinc: Poor intake, Reduced conversion to co-enzyme, Reduced storage in fatty liver; Inhibited intestinal absorption
- Impaired healing
- Liver regeneration retardation

- Immune function
What are the general functions of vitamin B1?
What conditions may be caused by deficiency of vitamin B1 (thiamine)?
Vitamin B1 is a water-soluble micronutrient which is phosphorylated in the gut to active coenzyme form
Vitamin B uses: - Cofactor: Pyruvate dehydrogenate, Alpha-ketoglutaric acid dehydrogenase - ATP production - Nerve conduction - Maintenance of neural membranes
Vitamin B1 deficiency = Beriberi Disease
