Which diabetes medication may cause genital mycotic infections because it increases glucose excretion in urine?
SGLT2 inhibitors.
A patient has fasting plasma glucose of 6.0 mmol/L on two separate tests. Does this meet the diagnostic criterion for diabetes?
No
Which type of diabetes accounts for approximately 90–95% of all diabetes cases worldwide?
Type 2 diabetes mellitus.
In which organ is insulin produced?
Pancreatic β-cells.
What is the main problem with insulin action in Type 2 diabetes?
Insulin resistance and relative insulin deficiency
A patient taking insulin suddenly becomes sweaty, shaky and confused. What should you suspect?
Hypoglycemia

Approximately how many adults worldwide are currently living with diabetes?
More than 800 million
When was insulin first successfully used to treat diabetes?
1922
Why can a person with Type 2 diabetes feel hungry even when blood glucose is high?
Glucose cannot be effectively used by cells because of insulin resistance/relative insulin deficiency.
Why can metformin be temporarily stopped during certain acute illnesses or situations with significant renal dysfunction?
Because the risk of metformin-associated lactic acidosis can increase in severe conditions.
A patient has HbA1c of 6.7%, but fasting glucose is normal. Can diabetes still be diagnosed?
Yes, if the HbA1c result is confirmed/appropriate and diagnostic criteria are met.
Approximately what proportion of adults with diabetes are estimated to be undiagnosed worldwide?
About 40%
How did doctors in ancient times identify diabetes?
By tasting the patient’s urine because it was sweet.
A patient with Type 1 diabetes stops insulin. Why can ketone bodies rapidly increase?
Severe insulin deficiency causes increased lipolysis and ketogenesis.
Which combination includes Metformin and a DPP-4 inhibitor?
Metformin + Sitagliptin.
A young patient has weight loss, polyuria, ketones in urine and high blood glucose. Which type of diabetes is more likely?
Type 1 diabetes.
A hospital studied 500 adults. Diabetes prevalence was 12%.
How many patients would be expected to have diabetes?
60

Bonus for Luck!
Two patients have glucose of 15 mmol/L. One is producing almost no insulin; the other has high insulin levels but insulin resistance. Which mechanisms are different?
Absolute insulin deficiency in Type 1 vs insulin resistance with progressive β-cell dysfunction in Type 2.
A patient with Type 2 diabetes has heart failure and chronic kidney disease. Which modern drug class may provide cardiorenal benefit even beyond glucose lowering?
Dapagliflozin и Empagliflozin
A 32-year-old patient is diagnosed with Type 2 diabetes, but he is lean, has no metabolic syndrome, quickly requires insulin, and has positive GAD antibodies. What diagnosis should be considered?
LADA (Latent Autoimmune Diabetes in Adults).
A patient has:
* Fasting plasma glucose: 5.9 mmol/L
* 2-hour OGTT glucose: 11.2 mmol/L
* HbA1c: 5.8%
Diabetes type 2
