My vaginal use to itch me anytime i took groundnut or suagr but my blood sugar is normal, what is the cause of the itching?

Possible yeast: Some patients are very sensitive to carbohydrates, sugar and starch in their diets. You may have a low grade yeast infection. Try lowering or removing sugar and starch from your diet for a while to see if it makes a difference. If you still have problems, see your health care provider...

"Fungus among us": The yeast orgasm likes warm, moist, highly glycogenated(high sugar) environments. Either cut back on your sugar and/or see a gyn md to test for a yeast(fungus) infection.
