Navigating Insulin Therapy: My Tips and What You Need to Know
When I started on intensive insulin therapy for my diabetes, it felt like a whole new world. This approach often involves using long-acting insulin to provide a steady baseline throughout the day, combined with short-acting insulin around mealtimes to cover the carbohydrates I eat. It's a precise science, and you absolutely must get thorough training from your doctor or a diabetes educator. Trust me, errors and miscalculations can land you in the hospital in a hurry.
How Insulin Works in Your Body
Think of insulin as the key that unlocks your body's cells, allowing glucose (sugar) from your bloodstream to enter and be used for energy. Without enough insulin, or if your body can't use insulin effectively, sugar builds up in your blood, leading to high blood sugar levels. Insulin therapy helps to replace or supplement the insulin your body isn't producing or using properly.
Different Types of Insulin
There are several types of insulin, categorized by how quickly they start working and how long their effects last:
Rapid-Acting Insulin: Starts working within 5-15 minutes, peaks in about an hour, and lasts 2-4 hours. It's typically taken right before meals.
Short-Acting (Regular) Insulin: Starts working within 30-60 minutes, peaks in 2-3 hours, and lasts 3-6 hours. It's usually taken 30 minutes before meals.
Intermediate-Acting Insulin: Starts working in 2-4 hours, peaks in 4-12 hours, and lasts 12-18 hours. Often taken twice a day.
Long-Acting Insulin: Starts working within 2-4 hours, has no peak, and lasts up to 24 hours or more. This provides a steady, background insulin level.
Ultra-Long-Acting Insulin: Even longer duration than long-acting, potentially lasting up to 42 hours.
Premixed Insulin: Contains a combination of two different types of insulin (e.g., rapid and intermediate), designed for convenience.
Insulin is available in various forms, including vials (for use with syringes) and pen injectors, which are pre-filled devices that make dosing easier. My personal experience taught me a crucial lesson: ask your doctor to prescribe your long-acting and short-acting insulin in different form factors! Early on, I had both in vials and, despite careful labeling, I mixed them up, accidentally injecting a dangerously large dose of short-acting insulin. It was a terrifying moment that required an ambulance ride and an emergency room visit. Learning from my mistake, I highly recommend getting one type in a pen and the other in a vial, or both in pens but with clearly distinct appearances, to avoid any mix-ups.
My Tips for Managing Insulin Therapy
Managing insulin effectively is truly a "second job." You need to constantly stay on top of your meals, meal timing, exercise, even temperature exposure, other medications, and your overall health. It's a lot to juggle, but here are some things I've found helpful:
Test Your Blood Sugar Often: This is perhaps the most important tip! Regularly testing your blood sugar with your glucose meter is vital. It's the only way to truly see how your insulin therapy is working, understand how your body reacts to different foods and activities, and most importantly, catch if your blood sugar is going too low, signaling you need to consume carbohydrates or seek medical attention.
Affordable Supplies: Syringes and needles can be surprisingly expensive. I've found the best deals without needing a prescription at Walmart or Sam's Club, often cheaper than what my commercial insurance would cover.
Smart Dosing App: The JadeDiabetes smartphone app has been a lifesaver for me (

Keeping Insulin Cool: Insulin needs to be kept at a cool temperature. When I'm out and about, I rely on my Frio Cooler (www.frioinsulincoolingcase.com/ Over-the-Counter Insulin (Use with Caution!): If you ever find yourself without healthcare access, older forms of insulin like Novolog are sometimes available over the counter at Walmart at affordable prices without a doctor's prescription. However, I absolutely do not advise doing this without medical advice! You need to understand the "half-life" (how long it stays active in your body) of the specific insulin to figure out dosing correctly, and that requires professional guidance.
Educate Yourself: I highly recommend reading Dr. Bernstein's Book, especially the sections on insulins and what to do if you get the flu. It's also smart to ask your doctor to prescribe his recommended "Sick Day" medications in advance.
Side Effects and Dangers of Insulin
While insulin is essential for managing blood sugar, it's important to be aware of potential side effects and dangers:
Hypoglycemia (Low Blood Sugar): This is the most common and immediate danger. If you take too much insulin, or don't eat enough after injecting it, your blood sugar can drop too low, leading to symptoms like shakiness, sweating, confusion, and in severe cases, seizures or loss of consciousness.
My Mitigation Strategy: Always, and I mean always, carry glucose tablets or some form of fast-acting sugar. I carry packets of a powdered sugar/glucose product designed for diabetics. It's compact and dissolves super fast in your mouth. Just remember not to inhale a puff of sugar when you pour it in!
Weight Gain: Insulin is a "building hormone," which means it promotes the storage of glucose as fat. This can make it harder to lose weight and is a common side effect of insulin therapy.
Inflammation: Some studies suggest that insulin, particularly at higher doses, can contribute to inflammation in the arteries. This is why newer glucose-lowering drugs are now mandated by the FDA to demonstrate a cardiac benefit before coming to market.
Injection Site Reactions: Redness, swelling, or itching at the injection site can occur. Rotating injection sites can help prevent this.
Lipodystrophy: This is a change in the fat tissue under the skin at injection sites, which can appear as a lump or dent. Again, rotating injection sites is key to preventing this.
Remember, managing diabetes with insulin is a continuous learning process. Always follow your doctor's guidance, and don't hesitate to ask questions or seek help if you're struggling. How often do you currently test your blood sugar, and what have you learned from it?
