2: Feel Sick and Tired
Your body is always working hard to cope with the increased blood sugar levels, making you feel tired. The cells of your body lack glucose, causing them to get slow in their functioning. The food you eat is not being processed completely, meaning fewer nutrients are transferred from food to your body.
However, not all diabetic patients have this symptom because some have an elevated sugar level for a few hours, so they do not feel sick and tired all the time.
