L14: Diabetes Diagnosis And Management Flashcards
What is diabetes
A state of altered glucose haemostasis that leads to hypeglycaemia (high glucose) when left untreated and results in micro and macro vascular damage
What is the oral glucose tolerance test
- You give patient a milk to drink
- Wait for 2 hours
- Take glucose
What happens in a normal glucose tolerance test
Blood glucose rises and then falls
What happens to the oral glucose tolerance test in diabetes
Blood glucose is significantly above the threshol and stays high
What is the renal threshold
When the glucose can become detected in the urine
What is type 1 diabetes
- An autoimmune condition when the beta cell in the pancreas are destoryed so they cannot release insulin
- Insulin cant convert glucose to glycogen to become stored in the liver
- There is high blood sugar as a result
What symptoms does type 1 diabetes present with
Thirst
Polyuria
Weight loss
Blurred vision
What is type 1 diabetes
When there is insulin but the body stops reacting to insulin so glucose cant be converted to glycogen to become stored
If a type 1 diabetic patient is symptomatic what test can be diagnostic
Random plasma glucose more than 11.1mmol/l
If a patient with type 2 diabetes is asymptomatic wgat is the diagnostic test we can carry out to diagnose
Fasting blood glucose above 7 Or 2hour post oral glucpse tolerance test more than 11.1 Or Hba1c greater than 48mmol/mol
What are the antibodies used in type 1 diabetes for diagnosis
Islet cell antibodies
Anitbodies to glutamic acid decarboxylase
In which type of diabetes is ketones likelt to be present
Type 1
How can we monitor diabetes
Capillary blood glucose testing
Urine testing
Hb1ac
Frucosamine
Why is urine testing not reliable
If there is renal glycosuria then the renal threshold for glucose is lower therefore there can be glucose in the urine when infact the patient has normal glycaemia
What is hb1ac
This is the glucose bound to the haemoglobin molcule non enzymeattically
