Frequent Urination (Polyuria): This is one of the most common and earliest signs of high blood sugar. Your kidneys work overtime to filter and absorb the excess sugar. When they can’t keep up, the sugar is excreted in your urine, pulling fluids from your tissues along with it.
Excessive Thirst (Polydipsia): Because you’re urinating so frequently, your body loses a lot of fluids, which triggers a feeling of intense thirst. This creates a cycle: you urinate more, which makes you feel thirstier, so you drink more.
Increased Hunger (Polyphagia): Despite eating, your cells aren’t getting the glucose they need for energy. This sends a signal to your brain that you are hungry, even after a meal.
Fatigue: When your cells can’t use glucose for energy, your body becomes starved for fuel. This leads to a constant feeling of tiredness and weakness, no matter how much you rest.
Blurred Vision: High blood sugar can cause the lens of your eye to swell, affecting your ability to focus. This can make your vision blurry and is often one of the first signs people notice.
