I keep reading that folks usually need less insulin on a pump compared to MDI.
Haven't got my pump yet, but they said you work out starting basal by:
- Add up a typical day's basal + boluses to arrive at total daily dose (TDD)
- Reduce TDD by 20%
- Divide by 24, the answer is hourly basal rate
-Then add boluses for food as per DAFNE-style ratios
Strikes me that unless your meal boluses are 20% or less of your TDD on MDI, you're going to be taking more insulin in total. Because the TDD includes food, but you calculate basal rate then ADD food boluses in again.
Is this a very rough formula which is rarely accurate? Or do you need less because you get a 'honeymoon' when you start pumping?
Does anyone know?
