Study Notes

Insulin Treatment

Insulin treatment is essential for managing diabetes as it plays a vital role in regulating blood glucose levels.
Individuals with type 1 diabetes require insulin therapy as their body does not produce it.
Type 1 diabetes requires a combination of basal (long-acting) and bolus (rapid-acting) insulins to mimic the body's natural insulin release.
Individuals with type 2 diabetes may require supplemental insulin as their bodies become resistant to the insulin produced.
The type, dosage, and administration schedule of insulin should be tailored to a client's unique needs.
Ongoing monitoring and adjustments are crucial to optimize insulin therapy and minimize complications.

Insulin Action

Insulin is produced by the pancreas and facilitates glucose uptake into cells.
Insulin regulates the body's metabolism of fats, proteins, and carbohydrates.
Insulin binds to cell surface receptors and opens glucose transporters, allowing the glucose to move into the cell, reducing blood sugar levels.
Insulin promotes glucose conversion into glycogen in the liver for storage and inhibits the breakdown of fat.
Insulin also contributes to protein synthesis and regulates lipid metabolism by preventing excessive breakdown of fats.

Diabetes and Insulin

Individuals with diabetes have compromised insulin production or utilization.
Insulin medications aim to mimic the body's natural insulin release to manage blood sugar levels within a normal range.

Type 1 Diabetes

No insulin production due to autoimmune destruction of beta cells in the pancreas.

Type 2 Diabetes

Insulin resistance occurs when cells fail to respond adequately to insulin.
Gradual decrease in pancreatic insulin production.

Insulin Types

Each type of insulin has distinct onset, peak, and duration characteristics, allowing for tailored treatment plans based on the client's needs.
Rapid-acting insulin works quickly and is ideal for managing blood sugar spikes post-meals.
Short-acting insulin has a slightly delayed onset and longer duration compared to rapid-acting insulin.
Intermediate-acting insulin provides longer-lasting effects, maintaining baseline blood sugar levels between meals and overnight.
Long and ultra-long-acting insulin (basal insulin) provides a steady level of insulin throughout the day and night, mimicking the basal rate of natural insulin production.

Rapid Acting Insulin

Insulin lispro (Humalog): 15-30 minutes onset, 1-2 hours peak, 3-6 hours duration.
Insulin aspart (Novalog): 10-20 minutes onset, 1-2 hours peak, 3-5 hours duration.
Insulin glulisine (Apidra): 10-15 minutes onset, 1-2 hours peak, 3-5 hours duration.

Short Acting Insulin

Regular Insulin (Humulin R, Novolin R): 30-60 minutes onset, 1-5 hours peak, 5-10 hours duration.

Intermediate Acting Insulin

*NPH Insulin (Humulin N, Novolin, N): 1-2 hours onset, 4-12 hours peak, 18-24 hours duration.

Long Acting Insulin

Insulin glargine (Lantus): 70 minutes onset, 6-8 hours peak, 24 hours duration.
Insulin detemir (Levemir): 1-2 hours onset, 6-8 hours peak, Up to 24 hours duration.

Ultra Long Acting Insulin

Insulin degludec (Tresiba): 1 hour onset, None, Up to 42 hours duration.

Total Daily Insulin Dose

Calculating insulin dosage involves understanding an individual's insulin needs, which can vary significantly based on body weight, diet, exercise level, and the presence of any additional health conditions.
The initial dosage is determined by providers, who make ongoing adjustments based on the client's blood glucose monitoring, dietary intake, activity levels, and overall health status.
Personalized and requires regular review and adjustment.

Insulin Treatment for Diabetes

Insulin is a hormone produced by the pancreas that regulates blood glucose levels.
Clients with type 1 diabetes require insulin as their bodies don't produce it.
Clients with type 2 diabetes may require supplemental insulin as their bodies become resistant to it.

Insulin Action

Insulin facilitates glucose uptake into cells and manages metabolism of fats, proteins, and carbohydrates.
Insulin binds to receptors on the cell surface, opening glucose transporters.
This allows glucose to enter the cell, reducing blood sugar levels.
Insulin also promotes glucose storage in the liver and inhibits fat breakdown.

Diabetes and Insulin

People with diabetes have compromised insulin production or use, leading to elevated blood sugar levels.
Insulin medications are prescribed to mimic natural insulin release and manage blood sugar.
Type 1 diabetes results from the pancreas producing little or no insulin due to autoimmune destruction of beta cells.
Type 2 diabetes results from insulin resistance, with cells failing to respond adequately to insulin and a gradual decrease in pancreatic insulin production.

Insulin Types

Insulin types have distinct characteristics, including onset, peak, and duration, allowing for tailored treatment plans.
Rapid-acting insulins work within minutes and manage post-meal blood sugar spikes.
- Examples: insulin lispro, insulin aspart, and insulin glulisine.
Short-acting insulin is regular insulin with a delayed onset and longer duration than rapid-acting insulins.
Intermediate-acting insulin is NPH insulin, providing a longer-lasting effect for maintaining baseline blood sugar levels.
Long- and Ultra Long-acting insulins are used to manage blood sugar throughout the day, providing a steady level of insulin.
- Examples: insulin glargine, insulin detemir, and insulin degludec.

Total Daily Insulin Dose

Insulin dosage calculation considers body weight, diet, exercise, and health conditions.
Dosage is personalized and requires regular adjustment based on blood glucose monitoring, diet, activity levels, and overall health status.
Total Daily Insulin Requirement (TDIR): Calculated based on the individual's weight and health condition.

Insulin Monitoring and Adjustments

Ongoing monitoring and adjustments are crucial for optimizing insulin therapy and minimizing complications.
Blood glucose patterns, lifestyle, preferences, and risk of hypoglycemia are all considered when making adjustments.

Considerations for Clients with Diabetes:

Hypoglycemia can occur if insulin dosage is too high or if clients don't eat according to their schedule.
Clients with diabetes should be educated on insulin therapy, glucose monitoring, and potential complications.

Insulin Treatment

Insulin therapy for Type 1 Diabetes is essential for survival and daily blood glucose control.
Type 1 Diabetes requires a combination of basal (long-acting) and bolus (rapid-acting) insulins mimicking normal insulin release.
Type 2 Diabetes insulin requirements vary based on disease progression, insulin resistance, and individual needs.
Type 2 Diabetes treatment often starts with oral medications, diet, and exercise but progresses to insulin therapy to address fasting hyperglycemia and mealtime glucose control.
Insulin type, dosage, and administration schedule are personalized, considering blood glucose patterns, lifestyle, preferences, ability to manage insulin therapy, and hypoglycemia risk.
Ongoing monitoring and adjustments are crucial for optimal therapy and managing complications.

Insulin Action

Insulin, produced by the pancreas, regulates blood glucose by facilitating glucose uptake into cells.
Insulin controls the metabolism of fats, proteins, and carbohydrates.
Insulin binds to cell surface receptors, opening glucose transporters allowing glucose to move into cells.
Insulin promotes glucose conversion to glycogen in the liver for storage and inhibits fat breakdown.
Insulin stimulates protein synthesis and regulates lipid metabolism by preventing excessive fat breakdown.

Diabetes and Insulin

Diabetes impairs the body's ability to produce or effectively use insulin, resulting in elevated blood sugar levels .
Insulin medication mimics natural insulin release to manage blood glucose levels.

Type 1 vs. Type 2 Diabetes

Type 1 Diabetes: Pancreas produces little or no insulin due to autoimmune destruction of beta cells.
