To absorb all of the extra sugar in your blood, your kidneys have to work extra hard. When they can't keep up, the body excretes it along with the water it needs.
2. Thirst Your body draws water from its tissues to flush out the excess sugar. A switch in your brain flips to tell you that you're thirsty so you'll drink more because you need that fluid to make energy, pass nutrients, and eliminate waste.
3. Mouth Dryness
As your body draws the fluid from your mouth, it can become dry and cracked at the corners. Infection is more likely when you have less saliva and more sugar in your blood. Gums may swell, and white patches on your tongue and within your cheeks may appear (your doctor will call this oral thrush). Drinking more water or chewing sugar-free gum will help.
4. Skin Problems
To get rid of excess blood sugar, the body draws water from all over. Dry, itchy, cracked skin, especially on the legs, elbows, feet, and hands, can result. High glucose levels can damage nerves over time. Diabetic neuropathy is the medical term for this condition. It can make cuts, wounds, and infections more difficult to detect. Without care, they may progress to more serious issues, such as the loss of a toe, foot, or a portion of the leg.
5. Sight Problems
Your body may be sucking fluid out of your eyes' lenses, making it difficult to concentrate. Furthermore, high blood sugar can damage blood vessels in the back of your eye (retina). This can result in long-term vision loss, if not blindness.
When you have type 2 diabetes and your blood sugar levels are consistently elevated, insulin, which helps transfer energy to your cells, becomes less receptive. You will become exhausted due to a lack of fuel. Type 1 diabetes causes exhaustion because the body is unable to produce its insulin. Your levels will stay high for a long time if you don't handle them properly. Your doctor will assist you by administering drugs and recommending lifestyle improvements.
You tend to lose your bearings when your blood sugar drops too low (hypoglycemia). You might slur your words or lose track of where you are. It can happen so quickly that you might not even notice you're behaving oddly. You may have a seizure or go into a coma in severe cases.
