constipation ,,diabetics have gastropathy mostly for that simpy take motility annhancers
Second your blood sugar levels this is in diabetic range but not diagnostic lets discuss criteria ,,,,,first take three morning readings after 12 hour fast if greater then 7 millimole its alarming,,,,second do HBA1c if greater then 6.5 percent again alarming,,,,third you have to take
glucose tolerance test which will be told to you in detail by the lab people,,,,screen your self for
kidney damag by performing renal function test,,,,get your fundoscopy done for some eye damage ,,,,if have
