Two Must-Have Books for people on Insulin or Pump Therapy

When moving to pump therapy, the idea of basal and bolus and how you use them in tandem does not make a lot of sense at first. There’s little to using long acting insulin such as Lantus than just injecting and letting it do its thing as far as your basal insulin is concerned.

But since your pump uses a short-acting insulin, you have to supply your basal insulin very small doses to mimic a long acting insulin 24 hour dose.

Getting your basal pump settings tuned is the foundation for successful pumping. In most cases you will need more than one basal rate to deal with uneven insulin requirement in the course of the day.”

The following two books have been indispensable books for me as I have tried to set basals, carb ratios, active insulin time etc. When I was first diagnosed, I struggled a lot with severe hypoglycemia.

“Think like a Pancreas” is probably the best book out there for optimizing your pump settings.

But reading Gary Scheiner’s book, “Think like a Pancreas” was just an eye opening experience. (See it on Amazon). This is the first book I would encourage anyone considering pump therapy or having trouble with BG control with their pump to get.

It might be the only book you will need to get up and running. Gary offers a myriad of real life scenarios and chances you’ll find a scenario that fits your case.

But if you want to delve deeper into the intricacies of the Insulin pump therapy, “Pumping Insulin” by John Walsh and Ruth Roberts will do the trick.

CGM Sensors

How Do Guardian/Enlite CGM Sensors Work?

Continuous Glucose Monitor

Continuous Glucose Monitoring (CGM) sensors are finicky, expensive and we all know of how much of a process it is for Medtronic to replace faulty sensors. For me, changing Medtronic CGM sensors is a ritual I do not look forward for many reasons. Getting my sensor inserted and working correctly seems to be a hit-or-miss proposition.

But the delicate nature of sensors is due to the fact they are miniature electrodes that are affected by small changes in the environment around them including small movements or presence of interfering chemical substances.

Auto Mode Pump Settings

Tunable Settings in Auto Mode for the MiniMed 670G

Tuning Auto Mode for the Medtronic MiniMed 670G is just like tuning an engine. Changing one setting throws off the other settings
Getting Auto Mode settings just right seems to be a balancing act – more fine tuning than just dialing settings up or down

UPDATE - I have certainly found out that dialing the Carb Ratio and Active Insulin time up and down do not necessarily mean that you will get better control. That is why it is important to work with your endo or educator to tune these settings.

——-

When it comes to Auto Mode for the MiniMed 670G, tuning the settings to get as close to your sugar targets feels a little more complicated as compared to the manual mode. This is because the closed loop system has a feedback mechanism which will likely throw-off one setting when you change another.

In the course of your day, the system is performing a balancing act between bolus and basal to keep you as close to Auto Mode’s fixed and preset BG target of 120mg/dL by introducing a third input – the micro bolus.

When it is all said and done, the user has control of two settings only, namely Carb Ratio (CR) and Active Insulin time (AIT).
