Sugar in the urine was one of the earliest Marine D3 Review tests for high blood sugar and diabetes. It used to be standard to check the urine with glucose test strips, which indicated whether high amounts of glucose were present. Fatigue can be a symptom of so many things, even of not getting enough sleep. But if you are thirsty and urinate more frequently, then feeling tired or fatigued might well be associated with high blood sugar symptoms.
The reason for fatigue from high blood sugar is because the blood sugar isn't going into your cells where you need it for energy. Your cells need glucose for energy to grow and heal, but the glucose isn't moving into the cells. It's staying in your bloodstream. When your cells don't get energy, you aren't going to feel very energetic either.
High blood sugar over time can affect your blood vessels. Some of the more easily affected blood vessels are in your eyes. If your vision changes or becomes blurry for any reason, you should see an eye doctor. Not only for glasses or contact lenses, but their exams can often detect other problems such as high blood sugar.
I don't mean the onset of personality disorders or anything like that. But the fatigue that results from high blood sugar is not limited to physical fatigue. It can affect how you feel day-to-day. You can become irritable and touchy. Or emotionally tired and lackadaisical. You may not care as much about things or even people that you ordinarily would feel strongly about.
