Can high blood sugar make you dizzy and nauseas?

High blood sugar, or hyperglycemia, can cause a range of symptoms, including dizziness and nausea. These symptoms can occur when blood sugar levels rise above the normal range, which is typically between 70 and 110 milligrams per deciliter (mg/dL) before eating and less than 140 mg/dL two hours after eating.

When blood sugar levels are too high, the body cannot effectively use glucose for energy, leading to a buildup of glucose in the blood. This can cause several symptoms, including:

- Dizziness: High blood sugar can affect the brain's ability to function properly, leading to dizziness, lightheadedness, and confusion.

- Nausea: High blood sugar can also cause nausea, vomiting, and abdominal pain.

- Other symptoms: Additional symptoms of high blood sugar can include excessive thirst, frequent urination, fatigue, blurred vision, and dry mouth.

It is important to note that dizziness and nausea can also be symptoms of other medical conditions., so it is important to see a doctor if you experience these symptoms, especially if they are accompanied by other symptoms of high blood sugar.
