When blood sugar levels are too high, it can cause a range of symptoms that can vary in intensity. The most common symptoms of high blood sugar include:
Excessive Thirst and Urination
When your blood sugar is too high, the body is unable to process all of the glucose in your blood. This causes the body to excrete excess glucose through urine, which leads to frequent urination. Along with this, the body also needs to replenish the fluids that are lost through urination, which can cause excessive thirst.
Fatigue
High blood sugar levels can cause the body to become tired and lethargic. The body has to work extra hard to process the excess glucose, which can leave you feeling exhausted and lacking in energy.
Blurred Vision
High blood sugar can cause changes in the shape of the lens of the eye, resulting in blurred vision. This is because the lens of the eye is made up of mostly water and glucose, and when there is an excess of glucose in the body, the lens of the eye can become distorted.
Slow Healing Wounds
High blood sugar levels can prevent wounds from healing properly, as they can interfere with the body's ability to fight off infection. This can cause wounds to take longer to heal, and can even lead to infections.
High blood sugar levels can also cause other symptoms, such as dizziness, headaches, and nausea. If you are experiencing any of these symptoms, you should speak to your doctor as soon as possible.
