Diabetes Flashcards
how is blood glucose concentration controlled
by the pancreas an endocrine gland that produces insulin and releases enzymes into digestive system to bring glucose concentration to normal
what happens if glucose levels are too high
the pancreas produces the hormone insulin to bring it back down
what does hormone insulin do
stimulates muscle and liver cells to take in glucose from the bloodstream
In which the excess glucose is converted into glycogen for storage
what does the pancreas do if glucose levels are too low
produce hormone glucagon that converts glycogen into glucose back into the blood
what is the negative feedback for glucose
- Insulin is produced when blood glucose rises and stimulates liver and muscle cells to convert excess glucose into glycogen to be stored
- hormone Glucagon is produced when blood glucose falls too low and stimulates liver and muscle cells to convert stored glycogen into glucose to be released into the bloodstream
what is type 1 diabetes
where pancreas produces little or no insulin resulting in glucose levels rising high enough to kill you
how can type 1 diabetes be treated
by insulin therapy where insulin is injected during meals to make sure glucose is removed quickly once food is digested preventing high glucose levels
what to keep in mind for type one diabetes
- limit carb intake so glucose levels are low
- regular exercise to keep excess glucose from blood
what is type 2 diabetes
where pancreas doesn’t produce enough insulin or resistant to insulin
what does type 2 diabetes lead to
uncontrolled high glucose levels
why do obese people have higher chance of type 2 diabetes
because likely to consume a diet rich in carbohydrates which causes an over-production of insulin resulting in the development of insulin resistance
