5.2 Diabetes Flashcards
in type 1 diabetes what are you unable to produce?
insulin
why dont you produce insulin? (Type 1)
beta cells in islets of langerhan don’t produce it
is the cause of type 1 diabetes known?
no
when does type 1 diabetes usually begin?
in childhood
what has it been suggested the immune system does in type 1 diabetes?
attacks its own beta cells
what can type 1 diabetes be controlled with?
regular insulin injections
a person with type 1 regularly checks their blood glucose concentration, how?
usually by pricking their finger
based on their blood glucose concentration what can a person with type 1 diabetes calculate?
how much insulin to inject
(Type 1) the amount of insulin injected does what to the amount of glucose absorbed by cells?
increases it
(type 1) the insulin injected also causes which g?
glycogenesis resulting in reduction of blood glucose concentration
when does hypoglycaemia occur?
when too much insulin is injected resulting in low blood glucose
when does hyperglycaemia occur?
when too little insulin is injected resulting in high blood glucose
what can be the result of hypoglycaemia and hyperglycaemia?
unconsciousness and even death
in type 2 diabetes what can you not effectively do?
use insulin to control blood sugar levels
what 2 things can happen in type 2 diabetes?
beta cells don’t produce enough insulin
body cells don’t respond properly to insulin
why can body cells lose responsiveness to insulin? (type 2)
glycoprotein insulin receptor doesn’t work so they don’t take up enough glucose
what is type 2 diabetes associated with?
excess weight
lack of exercise
overeating refined carbohydrates
your risk of type 2 diabetes increases with what?
age
are symptoms more or less severe in type 2 diabetes?
less
do symptoms of type 2 diabetes develop quickly or slowly?
slowly
what is the first line of action in treating type 2?
regulating carbohydrate intake and matching it with exercise levels
if overweight, what are type 2 patients encouraged to do?
lose weight
the second line of action in treating type 2 involves using drugs, what do they do?
stimulate insulin production
slow down the rate the body absorbs glucose from the intestine
what is the final course of action for type 2 diabetes?
injections
