This module is not approved as a discovery module
This module will enable students to develop an understanding of digestion, absorption, storage and utilisation of food in health and disease. It will promote enquiry into the relationships between diet, lifestyle, health and disease.
By the end of the unit the student will be able to:
1) demonstrate an understanding of the development, structure and normal working of the gastro-intestinal (GI) tract, and related organs, as an integrated semi-autonomous system;
2) demonstrate an understanding of the basic principles of human nutrition, and appreciate how diet can influence health and disease;
3) describe some common diseases affecting the GI tract, and the scientific basis for their treatment using surgery or drugs;
4) recognise how food intake and storage are normally co-ordinated with metabolic needs, and how diseases may disturb this process;
5) demonstrate an elementary understanding of how various chronic diseases cause disturbances of the energy balance, and how these respond to therapeutic intervention.
By the end of the unit students will know:
1) normal development, structure and normal working of the gastro-intestinal (GI) tract, and related organs, as an integrated semi-autonomous system;
2) the basic principles of human nutrition, and appreciate how diet can influence health and disease;
3) the aetiology and incidence of some common diseases affecting the GI tract, and the scientific basis for their treatment using surgery or drugs;
4) how food intake and storage are normally co-ordinated with metabolic needs, and how diseases may disturb this process;
5) the mechanism by which various chronic diseases cause disturbances of the energy balance, and how these respond to therapeutic intervention.
1) Application of scientific principles to medical practice as appropriate.
2) Application of anatomical dissection techniques.
1) Overview of the system as a whole:
Embryology, structure and function; integrated response to eating, digestion and metabolism; interactions between the major metabolic regulatory systems; the role of the GI tract in immune responses; major and minor constituents of food, diet, food values and nutritional requirements: introduction to artificial feeding.
2) Understanding upper GI function:
Salivation, chewing, swallowing, dysphagia; gastric structure and function; local gut reflexes and hormonal signalling systems; satiation; vomiting; helicobacterium pylori; principles of drug treatment of gastric and oesophageal complaints.
3) Understanding absorption:
Principles underlying normal function, malnutrition, malabsorption and food intolerance - anatomy, histology and ultrastructure of pancreas and small intestine; emulsification and hydrolysis of foodstuffs; local nervous system and hormonal signalling; uptake and enterocyte processing of sugars, amino-acids, minerals vitamins and fats; enterohepatic circulation of cholesterol and bile acids; common causes and nutritional consequences of malabsorption; inflammatory bowel disease.
4) Liver function:
Hepatic and biliary anatomy, histology and ultrastructure; metabolic and control function of the liver; common hepatobiliary disorders (jaundice and hepatitis); role of the liver in drug metabolism (recap); metabolic and social effects of alcohol and drug abuse.
5) Bowel function:
Anatomy and histology of the large intestine; gut transit times; change in bowel habit, diarrhoea, constipation; drug action; colorectal cancer.
6) Exercise and food utilisation:
Basic endocrinology in relation to normal nutrition and metabolism; integrated response to stress; effects of insulin, corticosteroids, glucagon and catecholamines; specialised metabolism in muscle and adipose tissue cells; metabolic effects of exercise and physical activity; blood glucose homeostasis; dietary effects and implications of type 1 and type 2 diabetes.
7) Obesity and eating disorders:
Lipid metabolism; leptin; eating behaviour; characteristics and development of eating disorders; escalation of obesity and approaches to management; social factors affecting physical activity and diet; physiological and metabolic responses to stress such as cold, infection, trauma and psychological insults.

Monitoring of progress in this strand will follow the student support model with local monitoring and feedback through regular meetings with tutors to look at progress periodically within the Nutrition and Energy ICU. A review of student progression overall will take place via examination boards and the Student Progress committee, incorporating academic and personal tutoring mechanisms.
