I am 79 years of age. I am a diabetic patient for more than 25 years and am on insulin. Last I had undergone KidneyBiopsy due my creatine level on very high side. I had taken 4 injections and the creatine level is almost normal. But the Potassium level is always slightly on the higher side. I would like to undergo a cataract surgery of my left eye, but due to my blood sugar fluctuating, unable to do the cataract surgery. Will you please advise as to how do I stabilise my blood sugar. For your information, I am also on Steroids i.e. Defcort 6 mg for the past more than 1 year Please advise.
