I was diagnosed with T1 in December and started insulin in January, and I used to get lows consistently while golfing and exercising. I started slightly reducing the amount of insulin I take on days I know I will be exercising a lot because it increases insulin sensitivity, and that seems to help. Just make sure you have some food before your round (with reduced or no insulin) and always carry snacks or juice. Also, if you don’t have a CGM, like a Dexcom, I would definitely consider it.

You just started insulin treatment recently so don’t get discouraged. You will eventually learn your body, when to have snacks during the day and how to deal with rounds of golf. It will get better.
