When you feel light-headed and have too much sugar in your pee, it can be worrisome. A lot of sugar in the pee could mean a lot of sugar in the blood, which might be a sign of diabetes. Symptoms of high blood sugar can include being thirsty, urinating often, and feeling very tired. To help with this, you need to eat healthy food and do exercises as well as check your blood sugar often. These are important steps for staying healthy after what you’ve found out so it would also be good if one could talk with a urologist about them.
