What is the role of the pancreas?
The pancreas produces insulin, which allows glucose to enter cells for energy or storage. Without insulin, glucose builds up in the blood (hyperglycemia), leading to complications.
What is Type 1 Diabetes (T1D)?
An autoimmune disorder where the body destroys the beta cells in the pancreas that make insulin. It results in little to no insulin production, causing glucose to remain in the blood.
What are the classic symptoms of Type 1 Diabetes?
Classic symptoms include polyuria (excess urination), polydipsia (thirst), polyphagia (hunger), weight loss, and dehydration.
What is the treatment for Type 1 Diabetes?
Requires lifelong insulin therapy (injections or pump).
What percentage of diabetes cases does Type 1 Diabetes account for?
Accounts for less than 10% of cases.
What is Type 2 Diabetes (T2D)?
Type 2 Diabetes accounts for 90–95% of all diabetes cases and is caused by insulin resistance and insulin deficiency.
What are the associated complications of Type 2 Diabetes?
Complications include dyslipidemia (abnormal levels of fats in blood), hypertension, kidney damage, nerve damage, and poor wound healing.
What lifestyle factors are linked to Type 2 Diabetes?
Closely linked with obesity, metabolic syndrome, and cardiovascular disease.
What is the treatment for Type 2 Diabetes?
Treatment includes lifestyle changes (diet, exercise, weight management), oral drugs, and sometimes insulin.
What targets are set for managing Type 2 Diabetes according to Diabetes Canada 2018?
Blood pressure < 130/80 mmHg and LDL cholesterol < 2.0 mmol/L (or ≥50% reduction from baseline).
What is Gestational Diabetes (GDM)?
Develops during pregnancy due to hormone-induced insulin resistance, increasing risks for both mother and baby.
What are the risks associated with Gestational Diabetes?
Increases risks for larger birth weight and higher risk of type 2 diabetes later in life.
Does Gestational Diabetes resolve after delivery?
Usually resolves after delivery but requires monitoring and sometimes insulin or diet control.
What is the goal of antidiabetic medications?
To maintain blood glucose (BG) within a normal range (normoglycemia) and prevent both hyperglycemia (too high) and hypoglycemia (too low).
What does A1C measure?
A1C measures average blood glucose over 2–3 months based on RBC lifespan.
What is the A1C goal for most adults with diabetes?
The goal is ≤ 7%.
What is the contribution of the past 30 days to A1C results?
Approximately 50% of the A1C result comes from the past 30 days.
What A1C level is diagnostic of diabetes?
A1C ≥ 6.5% is diagnostic of diabetes.
What is the more lenient A1C target for frail older adults?
A more lenient target of 7–8.5% may be used.
What are the fasting/pre-meal blood glucose targets according to Diabetes Canada?
The target is 4–7 mmol/L.
What are the 2-hour postprandial blood glucose targets?
The target is 5–10 mmol/L.
How is hypoglycemia defined?
Hypoglycemia is defined as ≤ 4 mmol/L.
Why do fasting glucose and post-meal glucose targets matter?
Fasting glucose reflects baseline control, while post-meal glucose shows how well the body handles sugar intake and treatment effectiveness.
What is the treatment approach for Type 1 Diabetes?
Type 1 Diabetes requires insulin therapy to reach glycemic targets.
