Can anyone advise a T2D? On Metformin 500mg couple years, no issues. In May increased to 1000mg as hba1c 7. Done again September and 6.9 at which point they increased to 2000mg. Bad effects so reduced to 1500mg October. Side effects ongoing/worsening with severe nausea and diarrhoea. So started SR Metformin last Monday. Still awful gastric issues so by now I feel basically awful. They decided to do tests and my calproctin test came back with high inflammatory markers so now they want to do urgent colonoscopy (also on naproxen which can affect results too). FITT test negative. Was told this with very sombre voice which obviously has increased anxiety. I keep saying this has literally all started since September since Metformin started being played with but no one is even hearing me. I know Metformin doesn't agree with everyone. Quite simply I dont know what to do next....
