Causes, Physical and Economic Effects of the above Diet Disorders: [ 2 examples each ]
OVER-NUTRITION
1. Obesity (excess weight): When energy intake is greater than energy expenditure.
Physical effects:
– Excess fat is stored in adipose tissue (fat)
– Cardiovascular System is working twice as hard
– Fatigue
– Stress on body joints
– Reduced body temperature control
– Conditions form such as: Gall bladder disease, Cardiovascular disease, Respiratory disorders and Diabetes
Economic effects:
– Cost of hospital treatment
– Surgery
– Medicine
– Toll on ability to work
– Absenteeism
2. Hypertension (high blood pressure): Excess sodium can cause an imbalance of water in body cells, so the body retains water causing the heart to pump blood under pressure.

Physical effects:
– High blood pressure
– Brain haemorrhage
– Stroke
– Heart failure
– Kidney disease
Economic effects:
– Cost of hospital treatment
– Surgery
– Medicine
– Toll of ability to work

– Low blood pressure
– Death in extreme cases
– Burnt oesophagus
Economic effects:
– Special wards
– Psychological counselling
– Use of expensive resources to treat the condition e.g. overseas clinics
2. Anaemia (Low iron in blood): Low iron in blood can result from:
Blood loss
Inadequate intake of iron
Reduced absorption of iron
Repeated pregnancies
Physical effects:
– Chronic lethargy
– Headaches
– Dizziness
– Heart palpitations as the heart pumps fasters to deliver required oxygen needs to muscles
Economic effects:
– Iron supplements needed
– Need to be treated with blood transfusions
