Always lose as much weight as feasible and keep moderately physically and mentally active and cut all extraneous sugars to see if optimal physical condition can alleviate dbt2....then, if not, use the meds...
Who knows if SWELL1 activity is affected by obesity?
I've lost 75 pounds so far (got about 25 to go) and it's made a huge difference in my blood sugar management. My last A1c was 6.4 (had been about 7.5).
