Study Notes
Type 1 and Type 2 Diabetes
- Type 1 Diabetes primarily results from autoimmune destruction of pancreatic β-cells.
- Type 2 Diabetes is often associated with insulin resistance and lifestyle factors.
- Common complications include cardiovascular disease and chronic kidney disease.
Diabetes Medications
- Metformin: Commonly causes gastrointestinal (GI) disturbances; notable for reducing hepatic glucose production.
- Sulfonylureas: Stimulate pancreatic insulin secretion; higher risk of hypoglycemia.
- SGLT2 Inhibitors: Promote weight loss and have a low risk of hypoglycemia; work by inhibiting glucose reabsorption in the kidneys.
- GLP-1 Agonists: Mimic glucagon-like peptide-1; beneficial for weight loss and reducing cardiovascular risk.
- Thiazolidinediones: Associated with fluid retention and an increased risk of fractures and bladder cancer.
Insulin Therapy
- Rapid-acting insulin has the fastest onset of action (0.25-0.5 hours).
- Long-acting insulin provides a "basal" level of insulin to maintain fasting glucose levels.
- A key adverse effect of insulin therapy is hypoglycemia, which occurs particularly if meals are missed after insulin administration.
Diagnosis and Monitoring
- The primary tests for diagnosing diabetes include Fasting Blood Glucose (FBG), Oral Glucose Tolerance Test (OGTT), Random Blood Glucose (RBG), and Glycated Hemoglobin (HbA1c).
- HbA1c is used for long-term glucose control monitoring.
Lifestyle and Management
- Lifestyle modification is the first step in managing newly diagnosed Type 2 Diabetes and gestational diabetes.
- Weight gain is not a typical symptom of diabetes; instead, symptoms include polyuria, polydipsia, and blurred vision.
Complications and Risks
- Ketoacidosis is a severe complication primarily associated with Type 1 Diabetes.
- Insulin resistance is often indicated by conditions such as acanthosis nigricans.
Drug Safety and Contraindications
- Metformin should be avoided in individuals with severe renal impairment.
- Thiazolidinediones should be used with caution in patients with heart failure.
- DPP-4 inhibitors (e.g., Sitagliptin) enhance incretin levels and lower blood glucose without significant risk of hypoglycemia.
Key Benefits of Treatment Options
- GLP-1 agonists reduce the need for insulin injections, promote significant weight loss, and have cardioprotective effects.
- Biguanides, like Metformin, improve insulin sensitivity and have a low risk of hypoglycemia.
Summary of Drug Classes
- Insulin Secretagogues: Include sulfonylureas, which increase insulin secretion from the pancreas.
- Biguanides: Include Metformin, reducing glucose production and improving insulin sensitivity.
- SGLT2 Inhibitors: Lower blood sugar by preventing glucose reabsorption in the kidneys.
- DPP-4 Inhibitors: Increase insulin release and decrease glucagon levels post meals.
Other Important Points
- Lifestyle changes are crucial for preventing the progression of Type 2 Diabetes.
- Management of Diabetes includes both pharmacological treatments and lifestyle interventions to achieve optimal blood glucose control.
