What does it feel like to have extremely high blood sugar levels?

Having extremely high blood sugar levels, a condition known as hyperglycemia, can lead to a range of symptoms and sensations. People with diabetes, especially those with uncontrolled diabetes, may experience these symptoms when their blood sugar levels become significantly elevated. Some common feelings and symptoms associated with high blood sugar levels include:

  1. Extreme Thirst: You may feel intensely thirsty and no matter how much you drink, you can’t seem to quench your thirst.
  2. Frequent Urination: You may need to urinate more often than usual, and the urine may be pale and abundant.
  3. Fatigue: High blood sugar can lead to feelings of extreme tiredness and lethargy.
  4. Frequent Hunger: Despite having high blood sugar levels, your body’s cells may not be receiving the glucose they need for energy, leading to persistent hunger.
  5. Blurred Vision: High blood sugar levels can affect the lenses in your eyes, causing temporary changes in vision and blurred vision.
  6. Dry Mouth and Dry Skin: You may experience a dry mouth and dry, itchy skin.
  7. Headaches: Some individuals report experiencing headaches when their blood sugar is elevated.
  8. Difficulty Concentrating: High blood sugar can impair cognitive function, making it challenging to concentrate and think clearly.
  9. Fruity Breath: In severe cases, your breath may develop a sweet, fruity odor due to the presence of acetone, a type of ketone that the body produces when it can’t use glucose for energy.
  10. Nausea and Vomiting: High blood sugar levels can lead to feelings of nausea and, in some cases, vomiting.
  11. Confusion: Extremely high blood sugar can cause confusion and, in severe cases, loss of consciousness.

It’s important to note that prolonged or severe hyperglycemia can be a medical emergency and requires immediate attention. If you or someone you know experiences these symptoms, especially if you have diabetes, it’s crucial to check blood sugar levels, follow your healthcare provider’s recommendations, and seek medical assistance as needed. Uncontrolled hyperglycemia can lead to diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS), both of which are serious and potentially life-threatening complications of diabetes. Regular monitoring, insulin or medication management, and adherence to a diabetes management plan are essential for keeping blood sugar levels within a healthy range.
