Diabetes
- Type 1
- The attack of the immune system
to your Beta cells in your islets of
Langerhans. So no insulin
produced by your pancreas.
- Can lead to hyperglycemia, due to a rise in blood
glucose level.
- As your kidneys cannot
reabsorb more glucose,
some is secreted via urine.
- This can be fatal as some of the blood vessels
can be affected, leading to death
- This can develop anytime in your life.
- To reduce blood glucose level, the
patient needs to inject the right
amount insulin.
- Insulin is a hormone/ a protein that binds
to the protein receptors of muscle cells
and liver cells
- This makes the membrane more
permeable by increasing number of
channel proteins, so more glucose is
taken in.
- This hormone can also activate enzymes which
convert glucose into glycogen, by glycogenesis,
which can be used for later.
- It increases the rate of respiration so more
glucose can get used up faster.
- Type 2 diabetes
- This develops at a later stage of a person's life.
- Can be inherited and is more likely in
people with a family history of this type.
- Its chance can increase by having a
poor diet, a lack of exercise and
being obese.
- Therefore, its chances can be reduced by exercising
more and eating more complex carbohydrates, as this
takes longer for your body to digest so blood glucose
concentration rises slowly.
- The body has more time to get rid of it.
- It usually occurs when the beta
cells in the islets of Langerhans
of the pancreas do not produce
enough insulin or your body
does not respond to it.
- This can cause your blood glucose
concentration to rise to a
dangerous level
- Hypoglycemia is when blood glucose
concentration falls below average levels.
- This is when your body rapidly turns glycogen into
glucose via glycogenolysis (breaking up of glycogen into
glucose) and gluconeogenesis (the forming of glucose from non-carbohydrates)
- This then increases the glucose level to normal.
- Adrenaline
- It is a hormone made by
adrenal glands, which
raises glucose
concentration, during
exercise.
- It activates glycogenolysis and
prevents glycogenesis. Glucagon does similar.
