Having raised blood/glucose levels carries with it increased risks. I was place on a low dose Aspirin 75mg twice daily 20 years ago when I suddenly lost my sight in one eye and glaucoma was then subsequently discovered as well as diabetes.
The Aspirin that I take is to keep my blood thinned and prevent any further blockages from occurring in my eyes. Many individuals I know are prescribed Warfarin for this very reason. You must also ensure that your cholesterol a, blood reassure and blood/glucose are well controlled if you are diabetic and that your diet is appropriate and avoids all those unhealthy saturated fats, and use only the beneficial ones.
