5. Increased Thirst and Frequent Urination
One of the most common warning signs of diabetes is feeling unusually thirsty and needing to urinate more frequently than normal. When blood glucose levels become too high, the kidneys work harder to remove excess glucose from the bloodstream. This process causes more water to be lost through urine, potentially leading to dehydration.
As a result, people may feel thirsty throughout the day, wake up several times at night to use the bathroom, or experience a persistently dry mouth. If these symptoms occur alongside unexplained fatigue or blurred vision, it is important to consult a healthcare professional and consider appropriate blood glucose testing.
6. Blurred Vision and Difficulty Concentrating
Changes in blood glucose levels can affect the fluid balance inside the eyes, temporarily altering vision. Some people may notice that their eyesight becomes blurry or fluctuates throughout the day.
