A Beginner’s Guide to Insulin for Persons with Diabetes

Insulin is a critical medication for many people with diabetes. It helps regulate blood sugar levels and prevents serious complications. If you're newly diagnosed with diabetes or your doctor has recently prescribed insulin, this comprehensive guide will provide you with a solid foundation of knowledge to manage your health effectively. We will explore the types of insulin, administration techniques, storage guidelines, potential side effects, and much more, ensuring you feel confident and well-informed on your journey.

What is Insulin and Why Is It Necessary?

Insulin is a hormone produced by the pancreas that allows glucose (sugar) from the food we eat to enter our cells to provide them with energy. In people with diabetes, either the body doesn’t produce enough insulin (Type 1 diabetes) or cannot effectively use the insulin it produces (Type 2 diabetes). This leads to high blood sugar levels, which, over time, can damage organs such as the heart, kidneys, eyes, and nerves.

Insulin therapy is often necessary to help manage blood glucose levels within a target range, thus reducing the risk of these long-term complications. While diet and exercise are essential components of diabetes management, many individuals require insulin to achieve optimal control.

Quick Recap of Diabetes Types:

  • Type 1 Diabetes: The body's immune system attacks and destroys the insulin-producing cells in the pancreas. People with Type 1 diabetes require insulin to survive.
  • Type 2 Diabetes: The body becomes resistant to insulin, and the pancreas may not produce enough insulin to overcome this resistance.
  • Gestational Diabetes: Develops during pregnancy, usually resolves after childbirth, but increases the risk of developing Type 2 diabetes later in life.
  • Other specific types of diabetes due to monogenic diabetes syndromes (such as neonatal diabetes and maturity-onset diabetes of the young [MODY]), diseases of the exocrine pancreas (such as cystic fibrosis and pancreatitis), and drug- or chemical-induced diabetes.

Why is Insulin Important?

  • Glucose Regulation: Insulin helps transport glucose from the bloodstream into cells, lowering blood sugar levels.
  • Energy Production: By enabling glucose to enter cells, insulin ensures the body has the energy it needs to function properly.
  • Preventing Complications: Maintaining healthy blood sugar levels with insulin reduces the risk of long-term complications associated with diabetes.

Example:

Imagine you've just eaten a meal. The carbohydrates from your food are broken down into glucose, which enters your bloodstream. Without sufficient insulin, this glucose would remain in your blood, leading to high blood sugar levels. Insulin acts like a "key" that unlocks the doors of your cells, allowing the glucose to enter and be used for energy.

Types of Insulin

Insulin comes in various forms, each differing in how quickly it starts working (onset), how long it lasts (duration), and when it reaches its peak effect. Understanding these differences is crucial for effective diabetes management.

Here’s a breakdown of common types of insulin:

| Insulin Type | Onset | Peak | Duration | Typical Use | | ---------------------------- | -------------- | ---------------- | -------------------- | -------------------------------------------------------- | | Rapid-Acting | 15-30 minutes | 1-2 hours | 3-5 hours | Mealtime insulin, correction of high blood sugar | | Short-Acting (Regular) | 30-60 minutes | 2-3 hours | 6-8 hours | Mealtime insulin, taken 30 minutes before eating | | Intermediate-Acting (NPH) | 1-2 hours | 4-12 hours | 12-18 hours | Basal insulin, covers insulin needs for half a day or overnight | | Long-Acting | 1-2 hours | No pronounced peak | 20-24 hours | Basal insulin, provides a steady level of insulin over 24 hours | | Ultra-Long-Acting | 6 hours | 36 hours | Provides background insulin for up to 36 hours | Basal insulin, provides a steady level of insulin over 36 hours | | Pre-Mixed | Varies by mix | Varies by mix | Up to 24 hours | Convenient, combines different types for convenience |

  • Rapid-Acting Insulin:

    • Starts working very quickly, typically within 15-30 minutes.
    • Often used to cover meals or to correct high blood sugar levels.
    • Examples: Insulin lispro (Humalog), insulin aspart (NovoLog), and insulin glulisine (Apidra).

    • Short-Acting (Regular) Insulin:

    • Starts working within 30-60 minutes.

    • Typically taken 30 minutes before a meal to cover the carbohydrates you're about to eat.
    • Example: Humulin R, Novolin R.

    • Intermediate-Acting Insulin (NPH):

    • Has a longer duration and is often used to provide basal (background) insulin coverage.

    • Typically injected once or twice a day.
    • Example: Humulin N, Novolin N.

    • Long-Acting Insulin:

    • Provides a steady level of insulin over 24 hours.

    • Used to cover basal insulin needs and usually taken once a day.
    • Examples: Insulin glargine (Lantus, Basaglar), insulin detemir (Levemir).

    • Ultra-Long-Acting Insulin:

    • Provides a steady level of insulin for longer than 24 hours.

    • Used to cover basal insulin needs and usually taken once a day.
    • Examples: Insulin degludec (Tresiba).

    • Pre-Mixed Insulin:

    • Combine a rapid-acting or short-acting insulin with an intermediate-acting insulin.

    • Offers convenience but less flexibility in adjusting individual doses.
    • Examples: Humulin 70/30, Novolin 70/30, NovoLog Mix 70/30.

Key Considerations:

  • Individual Needs: The best type of insulin for you will depend on your individual needs, lifestyle, and blood sugar patterns, as determined by your healthcare provider.
  • Multiple Daily Injections (MDI): Many people with diabetes use a combination of basal (long-acting) and bolus (rapid-acting) insulin to mimic the body's natural insulin release.
  • Insulin Pumps: Some individuals use insulin pumps, which deliver a continuous background dose of insulin and allow for bolus doses at mealtimes.

Knowing how to properly administer insulin is crucial for achieving optimal blood sugar control and avoiding complications. Insulin is typically administered through injections or insulin pumps.

Injection Methods:

  1. Syringes:

    • Insulin syringes come in various sizes (0.3mL, 0.5mL, and 1mL) and are marked with units of insulin.

    • Needle lengths vary, but shorter needles (4mm or 5mm) are generally preferred for comfort and to reduce the risk of injecting into muscle.

    • How to Inject with a Syringe:

      1. Wash Hands: Wash your hands thoroughly with soap and water.
      2. Prepare Insulin: If using NPH insulin, gently roll the vial between your hands (do not shake) to mix it properly.
      3. Draw Air: Draw air into the syringe equal to the dose of insulin you need.
      4. Inject Air: Insert the needle into the vial and inject the air.
      5. Withdraw Insulin: Turn the vial upside down and withdraw the correct dose of insulin.
      6. Check for Air Bubbles: Tap the syringe gently to remove any air bubbles.
      7. Clean Injection Site: Clean the injection site with an alcohol swab.
      8. Pinch Skin: Pinch up a fold of skin.
      9. Inject Insulin: Insert the needle at a 90-degree angle (or 45-degree angle if using a longer needle) and inject the insulin slowly.
      10. Release Skin Fold: Release the skin fold and remove the needle.
      11. Apply Pressure: Apply gentle pressure to the injection site, but do not rub.

  2. Insulin Pens:

    • Insulin pens are pre-filled with insulin and use a disposable needle.

    • They are convenient and often easier to use than syringes.

    • How to Inject with an Insulin Pen:

      1. Wash Hands: Wash your hands thoroughly with soap and water.
      2. Attach Needle: Attach a new pen needle to the insulin pen.
      3. Prime Pen: Prime the pen by dialing up 2 units and injecting them into the air until insulin comes out.
      4. Dial Dose: Dial the correct dose of insulin.
      5. Clean Injection Site: Clean the injection site with an alcohol swab.
      6. Pinch Skin: Pinch up a fold of skin.
      7. Inject Insulin: Insert the needle at a 90-degree angle (or 45-degree angle if using a longer needle) and inject the insulin slowly.
      8. Hold Needle: Hold the needle in place for 10 seconds to ensure all the insulin is delivered.
      9. Remove Needle: Remove the needle and dispose of it safely.

Injection Sites:

  • Common injection sites include the abdomen, thigh, upper arm, and buttocks.
  • Rotate injection sites to prevent lipohypertrophy (lumps under the skin).
  • The abdomen is generally the fastest site for absorption.

Insulin Pumps:

  • An insulin pump is a small, computerized device that delivers a continuous, controlled dose of insulin.

  • It's typically worn on a belt or in a pocket and connected to the body through a small catheter inserted under the skin.

    • Benefits of Insulin Pumps:

      • More precise insulin delivery.
      • Fewer injections.
      • Better blood sugar control.
      • Flexibility with meal timing and exercise.

    • Drawbacks of Insulin Pumps:

      • Cost.
      • Risk of skin infections at the insertion site.
      • Requires careful monitoring and training.

Proper Storage and Handling of Insulin

Proper storage and handling of insulin are essential to maintain its effectiveness and prevent degradation. Incorrect storage can lead to unpredictable blood sugar control.

Storage Guidelines:

  • Unopened Insulin:
    • Store unopened insulin vials and pens in the refrigerator (36°F to 46°F or 2°C to 8°C).
    • Do not freeze insulin. If insulin freezes, discard it.
    • Check the expiration date before use.
  • Opened Insulin:
    • Once opened, insulin can be stored at room temperature (up to 86°F or 30°C) for a specific period, typically 28-31 days, depending on the type of insulin.
    • Keep opened insulin away from direct heat and sunlight.
    • Note the date when you open the insulin vial or pen.
  • Traveling with Insulin:
    • When traveling, keep insulin in a cooler or insulated bag to maintain a stable temperature.
    • Carry a prescription or letter from your doctor stating that you require insulin.
    • Keep insulin with you in your carry-on luggage to avoid exposure to extreme temperatures in the cargo hold.

Handling Guidelines:

  • Inspect Insulin: Before each injection, inspect the insulin for any changes in appearance, such as cloudiness, clumping, or discoloration. Discard if any abnormalities are present.
  • Mix Insulin Properly: If using NPH insulin, gently roll the vial between your hands to mix it. Do not shake, as this can cause frothing and affect the accuracy of your dose.
  • Use Correct Syringe: Use the correct type of syringe that matches the concentration of your insulin (U-100).
  • Avoid Contamination: Do not share insulin pens or syringes with others to prevent the spread of infections.

Understanding Insulin Dosage and Adjustments

Determining the correct insulin dosage is a complex process that requires close collaboration with your healthcare provider. Factors such as diet, exercise, stress, and illness can all influence your insulin needs.

Key Concepts:

  • Basal Insulin: The background insulin that keeps blood sugar levels stable when you are not eating.
  • Bolus Insulin: The insulin taken to cover meals or correct high blood sugar levels.
  • Insulin-to-Carb Ratio: The amount of insulin needed to cover a certain amount of carbohydrates.
  • Correction Factor (Insulin Sensitivity Factor): The amount by which one unit of insulin will lower your blood sugar.
  • Target Blood Sugar: The desired blood sugar range you are aiming for.

Dosage Calculation Examples:

  1. Calculating Insulin-to-Carb Ratio:

    • Rule of 500: Divide 500 by your total daily insulin dose (TDD) to estimate your insulin-to-carb ratio.

    • Example: If your TDD is 50 units, your insulin-to-carb ratio is 500/50 = 10. This means 1 unit of insulin covers 10 grams of carbohydrates.

  2. Calculating Correction Factor:

    • Rule of 1800: Divide 1800 by your TDD to estimate your correction factor.

    • Example: If your TDD is 50 units, your correction factor is 1800/50 = 36. This means 1 unit of insulin will lower your blood sugar by 36 mg/dL.

  3. Adjusting Insulin Dosage:

    • Keep a detailed log of your blood sugar levels, food intake, and insulin doses.
    • Work with your healthcare provider to adjust your insulin dosage based on your blood sugar patterns.
    • Make small, gradual adjustments to avoid hypoglycemia.
    • Consider factors such as exercise, illness, and stress when adjusting your insulin dosage.

Example:

Suppose your target blood sugar is 100 mg/dL, and your current blood sugar is 200 mg/dL. Your correction factor is 36. To calculate the correction dose:

(200 mg/dL - 100 mg/dL) / 36 = 2.78 units. Round to 3 units for the correction dose.

Consulting Your Healthcare Provider:

  • Regularly review your insulin regimen with your healthcare provider.
  • Discuss any changes in your lifestyle, diet, or activity level.
  • Seek guidance on how to adjust your insulin dosage for special situations, such as travel or illness.

Monitoring Blood Sugar Levels

Regular blood sugar monitoring is an essential component of diabetes management, particularly when using insulin. Monitoring helps you understand how your body responds to insulin, food, and activity, allowing you to make informed decisions about your dosage.

Methods of Blood Sugar Monitoring:

  1. Blood Glucose Meters (Glucometers):

    • Traditional method of checking blood sugar by pricking your finger and placing a drop of blood on a test strip.

    • Provides immediate results and allows for on-the-spot adjustments to insulin dosage.

    • How to Use a Glucometer:

      1. Wash Hands: Wash your hands thoroughly with soap and water.
      2. Insert Test Strip: Insert a new test strip into the glucometer.
      3. Prick Finger: Use a lancing device to prick your finger.
      4. Apply Blood: Gently squeeze a drop of blood onto the test strip.
      5. Read Result: Wait for the glucometer to display the blood sugar reading.
      6. Record Result: Record the result in a logbook or app.

  2. Continuous Glucose Monitors (CGMs):

    • A CGM is a small device inserted under the skin that continuously tracks glucose levels in real-time.

    • It sends readings to a receiver or smartphone app, providing a more comprehensive view of blood sugar trends.

    • Benefits of CGMs:

      • Real-time glucose readings.
      • Alerts for high and low blood sugar levels.
      • Trend graphs to identify patterns.
      • Reduced need for finger pricks.

Frequency of Monitoring:

  • The frequency of blood sugar monitoring depends on the type of diabetes, insulin regimen, and individual needs.
  • People using multiple daily injections (MDI) may need to check their blood sugar several times a day.
  • Those using insulin pumps typically monitor their blood sugar more frequently.
  • Your healthcare provider will provide specific recommendations on how often to check your blood sugar.

Target Blood Sugar Ranges:

  • General target blood sugar ranges for people with diabetes:

    • Before Meals: 80-130 mg/dL
    • 2 Hours After Meals: Less than 180 mg/dL
    • A1C (Average Blood Sugar Over 3 Months): Less than 7%

  • These ranges may vary depending on individual circumstances and should be determined in consultation with your healthcare provider.

Tips for Effective Monitoring:

  • Keep a logbook or use a diabetes management app to record your blood sugar levels, food intake, insulin doses, and activity.
  • Review your blood sugar patterns with your healthcare provider regularly.
  • Adjust your insulin dosage based on your blood sugar levels and your healthcare provider's recommendations.

Recognizing and Managing Hypoglycemia (Low Blood Sugar)

Hypoglycemia, or low blood sugar, is a common and potentially dangerous side effect of insulin therapy. It occurs when your blood sugar levels drop too low, typically below 70 mg/dL.

Symptoms of Hypoglycemia:

  • Shakiness
  • Sweating
  • Dizziness
  • Hunger
  • Irritability
  • Confusion
  • Rapid heartbeat
  • Headache
  • Blurred vision
  • Weakness
  • Seizures (in severe cases)
  • Loss of consciousness (in severe cases)

Causes of Hypoglycemia:

  • Taking too much insulin
  • Skipping or delaying meals
  • Eating too few carbohydrates
  • Exercising without adjusting insulin
  • Drinking alcohol

Treating Hypoglycemia:

  1. Check Blood Sugar: If you experience symptoms of hypoglycemia, check your blood sugar immediately to confirm.

  2. Fast-Acting Carbohydrates: If your blood sugar is below 70 mg/dL, consume 15-20 grams of fast-acting carbohydrates. Examples include:

    • Glucose tablets or gel
    • 4 ounces (1/2 cup) of juice or regular soda (not diet)
    • 1 tablespoon of honey or sugar
    • Hard candies (check label for carbohydrate content)

  3. Recheck Blood Sugar: Wait 15 minutes and recheck your blood sugar. If it is still below 70 mg/dL, repeat the treatment with another 15-20 grams of carbohydrates.

  4. Meal or Snack: Once your blood sugar is back to normal, eat a meal or snack to prevent it from dropping again.
  5. Glucagon: For severe hypoglycemia (loss of consciousness), glucagon can be administered by a trained caregiver. Glucagon is a hormone that raises blood sugar levels quickly.

Preventing Hypoglycemia:

  • Work with your healthcare provider to adjust your insulin dosage to match your lifestyle.
  • Eat regular meals and snacks and avoid skipping or delaying meals.
  • Check your blood sugar before, during, and after exercise and adjust your insulin as needed.
  • Limit alcohol consumption.
  • Wear a medical alert bracelet or necklace to inform others that you have diabetes.

Educating Family and Friends:

  • Teach your family and friends how to recognize the symptoms of hypoglycemia and how to treat it.
  • Show them how to administer glucagon in case of severe hypoglycemia.
  • Keep glucagon on hand and make sure it is not expired.

Managing Hyperglycemia (High Blood Sugar) and Diabetic Ketoacidosis (DKA)

Hyperglycemia, or high blood sugar, occurs when your blood sugar levels are above your target range. If left untreated, it can lead to serious complications, including diabetic ketoacidosis (DKA).

Symptoms of Hyperglycemia:

  • Increased thirst

  2. Insulin Correction: Administer a correction dose of insulin as directed by your healthcare provider.
  3. Hydration: Drink plenty of water to help flush out excess sugar.
  4. Check for Ketones: If your blood sugar is consistently high (above 250 mg/dL), check your urine for ketones. Ketones are produced when your body starts burning fat for energy due to a lack of insulin.

Diabetic Ketoacidosis (DKA):

DKA is a serious complication of diabetes that can occur when there is a severe lack of insulin. It leads to a buildup of ketones in the blood, making it acidic. DKA is a medical emergency that requires immediate treatment.

Symptoms of DKA:

  • High blood sugar levels
  • High levels of ketones in urine
  • Excessive thirst
  • Frequent urination
  • Nausea and vomiting
  • Abdominal pain
  • Fruity-smelling breath
  • Rapid, deep breathing
  • Confusion
  • Loss of consciousness

Treating DKA:

DKA requires immediate medical attention. Treatment typically involves:

  • Insulin Therapy: Administering insulin to lower blood sugar levels and stop the production of ketones.
  • Fluid Replacement: Replenishing fluids lost due to excessive urination and dehydration.
  • Electrolyte Replacement: Correcting electrolyte imbalances caused by DKA.
  • Monitoring: Close monitoring of blood sugar levels, electrolytes, and ketones.

Preventing Hyperglycemia and DKA:

  • Take your insulin as prescribed by your healthcare provider.
  • Monitor your blood sugar levels regularly.
  • Follow a healthy diet and exercise plan.
  • Stay hydrated.
  • Manage stress.
  • Sick Day Management: Have a sick-day plan in place to manage your diabetes when you are ill. This may include checking your blood sugar more frequently, adjusting your insulin dosage, and monitoring for ketones.
