High blood glucose can cause changes in behavior and mood. A person experiencing high blood glucose may:
- feel irritated
- have difficulty concentrating
- complain of being tired
- become short tempered
In addition, fluctuations in blood sugars may lead to mood swings, irritability or tearfulness.
When blood glucoses are high for an extended period of time you may be drowsy or feel very tired. Other physical symptoms of high blood glucose levels may include frequent urination, increased thirst, blurred vision and headache. If you notice that you’re experiencing any of these symptoms, check your blood glucose level to see if it is elevated. Persistently high blood glucose levels can increase your risk of developing other health issues such kidney, nerve and eye disease and can raise your risk of having a heart attack or stroke. There are many things that can cause mood swings and behavior changes. I would suggest that you talk with your health care provider about any symptoms you might be having and share the results of your blood glucose testing.
