What are the effects of diabetes on thinking?
"Fuzzy brain" is often a term we can apply to the effect of high sugars on thinking, especially when one does not customarily run high sugars. It takes a lot of water to move molecules of sugar out of the body and this causes dehydration which can also cause "brain fog." People with chronically high sugars can be prone to yeast infections, another source of fatigue and fogginess. Diabetes in good control allows for a sharp mind, one of many goals for seeking management help and following a reasonable lifestyle plan.
