Hi I am type 2 diabetic. I am on slow release metformin (4 each morning) my blood sugars stay between 14 and 22. I admit not the best behaved diabetic but do try. I have however noticed that when I go to toilet (no 2) there are four white torpedo shapes in my stools and when I am sick which is most mornings due to phlegm (sorry to be graphic) there are 2 to 4 white torpedo shaped items. The only explanation I can come up with is my Metformin not digesting fully .. Please can I have your opinions. x
