6 Simple Rules for Insulin Pump Success

Updated: Dec 20, 2020

Earlier this year, Adam Brown counted 42 factors that affect glucose. That can overwhelm event the brightest process improvement engineer! But don’t worry; these six simple rules can standardize some of the most significant variables.


The TRUSTEEL/Sure-T should be changed every 2 days.

  1. Never go more than 2-3 days without changing your insertion set. No exceptions. See rule #2 for help.

  2. (TDD x 3) + 20 to 35 units = reservoir fill Find out the total daily dose (TDD) of insulin. Multiply that by 3. Add 20 to 35 units for tubing (and just in case you go HAM on tortilla chips and guacamole one day).

  3. Insertion site rotation: Most people are taught to alternate between the right and left sides of their body. The concern I have with this technique is that its its typical to go right back over the same site ripped off three days ago. That is not enough time for the site to heal. Instead, place the next site 2 inches away from the current. Three days later, move another 2 inches the same direction. Once you run out of real estate, move to the other side of your body and repeat. Your skin will thank you, and insulin absorption will be more predictable.

  4. If the insertion site hurts, change it.

  5. Bolus timing: Bolus for meals before eating. How soon before? It depends on your blood sugar.
