1. Constant Thirst
When your blood sugar levels are high, your kidneys work overtime in order to filter and absorb the excess sugar. This can cause dehydration, making you feel constantly thirsty.

2. Frequent Urination
This is another indication of high blood sugar. This might not seem like a big deal at first, but it could be one of the more dangerous signs that your blood glucose level is too high. When glucose remains in the system for a longer time, it can draw water from just about every organ within your body, causing it to shrink slightly.

A loss of water will result in dryness throughout the entire system, including the bladder, which means you’ll have to go more frequently than usual. You might have to urinate up to 20 times in a single day even when your body doesn’t need the water, especially concerning those whose kidneys are already affected by diabetes.

Staying hydrated is an important part of maintaining healthy blood sugar levels throughout the system, so ensure you’re drinking enough fluids every day.

3. Extreme Hunger
While you might think that increased hunger is a sign of low blood sugar, it can also indicate high levels and complications with moving that glucose into your cells to be used. When your body can’t effectively use the glucose in your blood, it signals your brain that you need more food, causing you to feel hungrier than usual.
