Insulin doesn’t have to be confusing when learning how to treat Type 1 and Type 2 diabetes mellitus. In this lecture from This is Why, Dr. Busti will explain how to quickly recognize insulin types, predict onset/peak/duration, and apply basal–bolus dosing concepts to real-world Type 1 and Type 2 diabetes care.
You’ll learn how to:
- How to identify rapid-, short-, intermediate-, and long-acting insulin for Diabetes
- The difference between basal insulin vs bolus (mealtime) insulin
- How basal–bolus regimens work (plus common pitfalls)
- Practical tips for insulin administration, timing with meals, and avoiding errors
- High-yield clinical points you’re likely to see in courses and on exams
Insulins covered (for memorization + exam success):
- Rapid-acting: insulin lispro, aspart, glulisine
- Short-acting: regular insulin
- Intermediate-acting: NPH insulin
- Long-acting / basal: insulin glargine, detemir, degludec
- Premixed options: 70/30 mixes (NPH/regular and related premixed products)
The goal = make medical education easy and clinically relevant.
