linking minor illness with major disease Flashcards
obvious examples of minor illnesses that can be due to major diseases
- infections
- skin
- GI/GU bleeding
factors that can influence minor illnesses becoming major
- ageing
- genetics
- lifestyle
- work
- behaviour
- peer influences
is ageing a disease
no its a risk factor
does ageing occur at different rates
yes, among individuals and within individuals
does ageing cause symtoms
no due to physiological functional reserve
characteristics of ageing
- cellular and physiological deterioration
- increased morality with age following maturation
-increased vulnerability to disease
how does ageing decrease ability to adapt to stress
- impaired homeostasis
- ateriosclerosis
what influences ageing
- genetics
- physiology
- lifestyle
- socioeconomics
what changes in vascular smooth muscle due to after load
- increased thickness of intima and media
what after load changes in the matrix of vascular smooth muscle take place
- collagen deposition, increased fibronectin, crosslinking (AGEs)
- fragmentation of elastin, calcium deposition
net result of after load changes on vascular smooth muscle
vascular stiffness
what age associated changes take place in cardio physiology
- maintenance of resting left ventricular function
- decreased ability to compensate for stress of impaired LV function
- blunted heart rate response to exercise requires a compensatory increase in SV to increase CO
lifestyle factors that influence minor illnesses becoming major
- smoking and alcohol consumption (children)
- nutrition (children)
- physical activity (children)
- overweight and obesity (children)
- supply of fruit and veg for consumption
- tobacco consumption (adults)
- alcohol consumption (adults)
- overweight and obesity (adults)
characteristics of type 2 diabetes
- age onset
- related to lifestyle
- implications of morbidity and mortality
how does type 1 diabetes work
beta cells produce little or no insulin
