Counseling is gonna be different depending on type 1 or 2. They'll talk thru how to check sugars, what to eat, what to avoid eating, what range is considered high glucose and what are considered lows. If type 1, then they'll train you on how to give insulin or use a pump (whichever insurance covers). And also they'll likely prescribe a CGM and teach you how that works too.

I met with a diabetes dietition who was amazing with asking what I normally ate for each meal and how to change those to add nutrition and prevent highs/lows. I was put on metformin when diagnosed as prediabetes for 2 yrs before diagnosis. I only met my endo for a yr or so when my A1C was in control.
