Correct. High blood sugar, or hyperglycemia, can present several noticeable signs that indicate glucose levels may be elevated. Recognizing these symptoms early is crucial for managing and adjusting treatment to prevent more severe complications:

• Frequent Urination: The body tries to excrete excess sugar through urine.

• Increased Thirst: Accompanies frequent urination as the body attempts to replenish lost fluids.

• Vision Changes: Blurred vision may occur as high blood sugar levels cause the eye's lens to swell.

• Increased Fatigue: High blood sugar can impair the body's ability to use glucose for energy, leading to tiredness and reduced stamina.

These symptoms underscore the importance of regular monitoring and management of blood sugar levels in individuals with diabetes.
