Q: I am a diabetic. Three weeks ago my blood sugar sky-rocketed to 500 plus and I became very ill. But strangely my vision appears to have improved. My glasses are too strong and I don't need them to drive anymore. Is this the lull before the storm? I also found a small red spot just on the inside of my vagina, which is very uncomfortable. It has become smaller and has almost completely disappeared. Is it a result of my high glucose reading?

A:The eye lens can undergo refractory changes in its power during fluctuating blood glucose levels. As a result the power can seemingly change. These changes are usually temporary and you should wait for stabilization of your blood glucose levels before deciding on the correct prescripion of spectacles. About the red spot in your vagina, it is unlikely to have improved due to high blood glucose.
