Monitoring of diabetes Flashcards
What are the benefits of improved glucose control?
reduced risk of microvascular and macrovascular complications as well as enhanced well-being and overall health
What can cause a decrease of HbA1c?
haemolytic anaemia; acute/chronic blood loss; pregnancy
What is normal HbA1c?
below 42mmol/mol
What is HbA1c indicateing prediabetes?
42-47mmol/mol
what is a HbA1c indicating diabetes?
over 48mmol/mol
What is the target for HbA1c?
48- 53mmol/mol
what is the limitation of HbA1c?
can have same average with little varibaility in BG as well as lots of variability
What happens during intensive drug therapy in terms of defense against hypoglycaemia?
the glucose threshold for release of adrenaline is lower, and the point at which they feel the hypo, is much lower BG
What is the difference between the hormone responses to hypoglycaemia in type 1 diabetics and normal individuals?
In normal individuals, they can stop their insulin release and release counterregulatory hormones eg glucagon and adrenaline. In T1DM, they have no insulin to turn off and the counttergulatory and symptom responses are decreased in intensity and occur at lower glucpse
What is the significance in the differences in responses to hypoglycaemia?
the window between recognition of hypoglycaemia and ability to take action before there is significant impairment of cognition is reduced leading ot higher risk of severe hypos
What are other reasons for hypoglycaemia?
primary failure of horomones to raise glucose; prolongation of insulin effects; exaggerated mismatch between insulin and nutrient absorption; listeyle contribution
What would cause hormones to fail to raise glucose?
hypopituitarism; adrenal cortical failure; isolated GH deficiency
what may cause prolongation of insulin effects?
renal impairment; hypothyroidism; liver failure;
What may cause an exaggerated mismatch between insulin and nutrient absoprtion?
malabsorption; delayed insulin administration
What are liestyle contributors to hypoglycaemia?
acute increase in glucose uptake with exercise; depletion of liver glycogen with vigorou/prolonged exerces; alcohol suppresion of gluconeogensis
