Study Notes
Insulin Therapy
- Definition: Insulin therapy involves the administration of insulin to manage blood glucose levels in diabetic patients.
-
Types of Insulin:
- Rapid-acting (e.g., Lispro, Aspart): Onset within 15 minutes, duration of 3-5 hours.
- Short-acting (e.g., Regular insulin): Onset 30 minutes, duration 5-8 hours.
- Intermediate-acting (e.g., NPH): Onset 1-2 hours, duration 10-16 hours.
- Long-acting (e.g., Glargine, Detemir): Onset 1-2 hours, duration up to 24 hours.
- Administration: Subcutaneous injection is the most common route.
- Monitoring: Requires regular blood glucose monitoring and adjustment of doses based on carbohydrate intake and activity levels.
Oral Hypoglycemics
-
Classes of Medications:
- Sulfonylureas (e.g., Glipizide, Glyburide): Stimulate insulin release from the pancreas.
- Biguanides (e.g., Metformin): Decrease hepatic glucose production and increase insulin sensitivity.
- Thiazolidinediones (e.g., Pioglitazone): Improve insulin sensitivity in muscle and adipose tissue.
- DPP-4 Inhibitors (e.g., Sitagliptin): Increase incretin levels, promoting insulin secretion and decreasing glucagon levels.
- SGLT2 Inhibitors (e.g., Canagliflozin): Increase glucose excretion in urine by inhibiting SGLT2 in the kidneys.
- Side Effects: Can include hypoglycemia, gastrointestinal upset, weight gain, and risk of heart failure with some classes.
Complications Of Diabetes
-
Acute Complications:
- Hypoglycemia: Low blood sugar leading to confusion, dizziness, and potential unconsciousness.
- Diabetic Ketoacidosis (DKA): Occurs mainly in Type 1 diabetes, characterized by high blood sugar, ketones in urine, dehydration, and acidosis.
- Hyperglycemic Hyperosmolar State (HHS): More common in Type 2 diabetes, severe high blood sugar without ketosis.
-
Chronic Complications:
- Microvascular: Nephropathy (kidney damage), retinopathy (eye damage), neuropathy (nerve damage).
- Macrovascular: Increased risk of cardiovascular disease, stroke, and peripheral artery disease.
Patient Education
- Blood Glucose Monitoring: Importance of regular self-monitoring of blood glucose levels.
- Diet and Nutrition: Emphasis on balanced diet, carbohydrate counting, and healthy food choices.
- Exercise: Regular physical activity to improve insulin sensitivity and overall health.
- Medication Adherence: Importance of taking medications as prescribed and understanding their side effects.
- Recognizing Symptoms: Training on recognizing symptoms of hyperglycemia, hypoglycemia, and other complications.
Recent Advancements In Diabetes Drugs
- GLP-1 Receptor Agonists: New classes of medications that enhance glucose-dependent insulin secretion and promote weight loss (e.g., Liraglutide, Semaglutide).
- Novel Insulin Formulations: Development of biosimilar insulins and more stable insulins for flexible dosing.
- Combination Therapies: Use of fixed-dose combinations to simplify treatment regimens.
- Smart Insulin Delivery Devices: Advancements in insulin pens and pumps that allow for better control and convenience.
- Bariatric Surgery: Emerging evidence supporting its efficacy in treating Type 2 diabetes in obese patients.
Insulin Therapy
- Insulin therapy is used to manage blood sugar levels in diabetic patients.
- Insulin types include rapid, short, intermediate, and long-acting.
- Rapid and short-acting insulins are used for mealtime coverage.
- Intermediate and long-acting insulins are used for baseline coverage.
- Insulin is typically administered subcutaneously through injections.
- Regular blood glucose monitoring and insulin dose adjustments are crucial.
Oral Hypoglycemics
- Multiple classes of medications are available to manage blood sugar.
- Sulfonylureas stimulate the pancreas to release insulin.
- Biguanides decrease liver glucose production and improve insulin sensitivity.
- Thiazolidinediones improve insulin sensitivity in muscle and fat.
- DPP-4 inhibitors increase incretin levels, promoting insulin secretion and decreasing glucagon levels.
- SGLT2 inhibitors increase glucose excretion in urine.
- Side effects include hypoglycemia, gastrointestinal upset, weight gain, and potential heart failure risk.
Complications Of Diabetes
- Acute complications include hypoglycemia, diabetic ketoacidosis (DKA), and hyperglycemic hyperosmolar state (HHS).
- Hypoglycemia occurs when blood sugar is too low.
- DKA is a dangerous condition mainly in Type 1 diabetes characterized by high blood sugar, ketones in the urine, dehydration, and acidosis.
- HHS is more common in Type 2 diabetes and involves severe high blood sugar without ketosis.
- Chronic complications include microvascular and macrovascular complications.
- Microvascular complications involve nephropathy (kidney damage), retinopathy (eye damage), and neuropathy (nerve damage).
- Macrovascular complications include increased risks of cardiovascular disease, stroke, and peripheral artery disease.
Patient Education
- Blood Glucose Monitoring: Regular self-monitoring of blood glucose levels is essential.
- Diet and Nutrition: A balanced diet, carbohydrate counting, and healthy food choices are paramount.
- Exercise: Regular physical activity is crucial to improving insulin sensitivity and overall health.
- Medication Adherence: It is important to take medication as prescribed and understand its side effects.
- Recognizing Symptoms: Learning to recognize symptoms of hyperglycemia, hypoglycemia, and other complications is key.
Recent Advancements In Diabetes Drugs
- GLP-1 receptor agonists are a new class of medications that enhance glucose-dependent insulin secretion and promote weight loss.
- Development of biosimilar and more stable insulins for flexible dosing.
- Fixed-dose combination therapies simplify treatment regimens.
- Smart Insulin Delivery Devices improve control and convenience.
- Bariatric surgery is emerging as a potentially effective treatment for Type 2 diabetes in obese patients.
