Hyperglycemia, or high blood sugar, presents with several characteristic symptoms. Extreme thirst occurs because the body attempts to dilute high glucose levels in the blood, leading to increased thirst. Frequent urination happens as the kidneys work to expel the excess sugar through urine, pulling water along and causing dehydration. Fruity breath is another tell-tale sign, particularly in diabetic ketoacidosis, where the body starts breaking down fats instead of glucose, producing ketones that emit a fruity odor.

Shakiness is typically associated with hypoglycemia, or low blood sugar. When blood sugar levels drop too low, it can cause the body to respond with symptoms such as shakiness, anxiety, and confusion. Thus, it does not align with the symptoms of hyperglycemia, making it the correct choice as the symptom that does not belong.
