List 4 eating disorders

Anorexia Nervosa
Bulimia Nervosa
Binge Eating Disorder
Disordered eating and dieting


List 5 risks of anorexia

Anaemia (iron deficiency)
Compromised immune system
Loss or disturbance of menstruation in girls and women
Kidney failure


What are the key characteristics of Bulimia Nervosa? (5)

Binge eating
Misusing laxatives or diuretics
Fasting then binging
Excessive exercise


List 4 key characteristics of Disordered Eating

Fasting or chronic restrained eating
Skipping meals
Unbalanced eating (restricting a major food group e.g. 'fatty' foods or carbohydrates)
Laxative, diuretic and enema misuse


What is the equation for BMI?



List 3 characteristics of fast food linked to increased adiposity

Higher energy density
Greater saturated fat
Reduced complex carbohydrates and fibre


Name the 2 hormones that have an influence on energy balance



What is the role of leptin?

A mediator of long-term regulation of energy balance
Suppresses food intake = induces weight loss
Produced in white adipose tissue
Inhibits appetite in the hypothalamus


How is leptin thought to be linked to some people's obesity?

Possible that a defective obesity gene causes inadequate leptin production - so brain receives an under assessment of the body's adipose stores and an urge to eat
Has also been proposed that obesity could be caused by defective receptor action - which increases a person's resistance to satiety


What is leptin's role in starvation?

Leptin levels fall during starvation
Leptin has an effect on regulating neuroendocrine adaptation to starvation - reduces fertility (lack of menstruation)


What is the role of ghrelin?

Fast-acting hormone
Plays a role in meal initiation - stimulates hunger
Produced in stomach and pancreas
Levels increase before meals and decrease after meals


List 4 consequences of Obesity Syndrome (Metabolic Syndrome)

Glucose intolerance and insulin resistance leads to Type 2 diabetes
Inflammation and increase in angiotensinogen leads to hypertension/CHD
Increased visceral adipose tissue causes fatty liver disease
Sleep apnoea


List 3 things that the pharmacist is responsible for in the care of obese patients

Helping people recognise the problem and the associated risks
Providing information leaflets with regard to healthy eating and exercise
Motivational interviewing to make changes in their lifestyle


What is Orlistat?

Taken with meals
Inhibits pancreatic lipase (breaks down triglycerides in ingested fat) and so increases excretion of dietary triglycerides
Prevents approx. 30% of dietary fat from being absorbed
60mg and 27mg chewable = P (Alli)
120mg = POM (Xenical)


List 4 benefits of using Orlistat to lose weight

Decreases in:
Visceral fat
Blood pressure
LDL cholesterol
Increase in insulin action
