Medical act 2.3 Flashcards
explain which oral meds to use for T2DM
metformin - reduces insulin resistance
repaglinide - increases insulin sensitivity
whats is insulin deficiency
decreased hormone secretion and insulin resistance
define Diabetes mellitus
deficiency of insulin secretion by beta cells in islets of langerhans or deficiency due to lack of response of cells to insulin
explain use of metformin
only in t2dm patients
used to lower blood glucose
reduces production of glucose
increases insulin severity in muscles 0 which helps absorb glucose better and lowers blood circulating glucose
disappearance of DM symptoms eg dry mouth, polyuria, thirst
explain use of gliclazide
used for t2dm
- increases insulin release in pancreas - means more glucose uptake from blood - decrease in blood glucose
which form of insulin replacement is the rapid onset acting insulin? how long does it last?
injection in the abdomen, starts within 20mins, lasts for 2-8hrs
where is the slow onset long acting insulin injected?
leg (lasts 24hrs)
describe meds for T1DM
insulin replacement (injections or pump device)
insulin fluid injected into the blood circulation
when should insulin dose should be adapted, under which circumstances?
- infection + high fever
- throwing up
- operation
explain hypoglycemia
too much insulin, too low blood glucose in blood (common in T1DM, due to heavy exertion, error in dosage, skipping a meal after taking insulin, throwing up)
when hypoglycemia is going for too long, what are the consequences?
neurological functioning affected (since NS uses fats and proteins for synthesis)
leads to poor conc, dizzy gait, slurred speech, lack of coordination
- INCREASES SYMPATHETIC NS STIMULATION so
- increased heart rate
- pale moist skin
- fear tremor
treatment for hypoglycemia
immediate quick carb intake eg sweet juice
what is diabetic ketoacidosis
insufficient insulin, too high blood glucose
Signs symptoms of diabetic ketoacidosis
- dehydration
- deep rapid breathing
- acetone breath
- metabolic acidosis - loss of consciousness
- electrolyte imbalance (abdominal cramps, nausea, vomiting, weakness)
treatment for diabetic ketoacidosis
supplement insulin, electrolytes, fluids
name which complications can happen in T1DM
hypoglycemia
diabetic ketoacidosis
name which complications can happen in T2DM
Hyperosmolar hyperglycemic nonketonic coma
name symptoms of hyperosmolar hyperglycemic nonketonic coma
- hyperglycemia
- dehydration
- neurological deficits
- muscle weakness
- difficult speech
- anormal reflex
which complications is hard to diagnose
hyperosmolar hyperglycemic no ketonic coma
explain microangiopathy
disease of small vessels
obstruction or tearing of capillaries or arteries
explain macroangiopathy
affects large blood vessels
can lead to atherosclerosis - myocardial or heart attack
wounds
amputation
