Low carb.

Hugs to Hkc for that awesome result Happy midweek

The bot gave you good answer. The medtronic pump works with a Dexcom 7 CGM. There is a new one on the market called Tandem. They say it is better the Medtronic. But it's whatever your insurance will cover
A dietician will help you figure out your carb to insulin ratio. You need to talk to @A DiabetesTeam Member T1 31 years. She prefers MDI. Good luck. Hope you find the answers you are looking for.

Hugs to GrayhamLamb for comments posted have a great weekend

Some of it depends on your lifestyle and insurance

A good pump takes all the thinking out of it and it is the best way to keep your blood sugar controlled - it doesn't forget to inject, tests constantly and adjusts

If you are quite active a POD might be a better option - slap it on for 3 days at a time and it does it's thing run by an app/sensor

Injecting may also work for you - it's all about lifestyle and circumstance. If you learn to dynamically dose it can be a super effective way to actively manage

Low Carb is a MUST for insulin users or you WILL gain weight. Body Fat is produced when you have extra sugar (which all diabetics do) and extra insulin in the blood (and if you are supplementing you have extra)

Insulin would let you eat that cake or pizza and just "shoot up" to take care of the blood sugar, but it will get turned into body fat, which makes the insulin resistance worse which would then require more insulin and the wheel goes round - so yes, Low Carb

How much insulin you use a day and what type is as individual as your DNA

The average person (non-diabetic) needs about the equivalent of 45 units of insulin a day - 38'ish to deal with 3 meals a day and another 7-8 for fasting periods but that is with Zero Insulin Resistance

So if you are at 50% resistance and only at 70% production you would need 90 units just to overcome the resistance and can only count on producing 30ish yourself so you would be 60 units "short" and you would dose that at intervals (meals) as needed and before bed if you need help with your fasting insulin levels as well

Dynamically dosing at meals would entail counting the carbs before you eat and then applying your personal "insulin to carb ratio" to that particular meal

New Bolus users (fast acting at meal time) may start with 1 extra unit for every 15 carbs consumed in a meal and then it will be adjusted up/down from there until your ratio is figured out
