High blood sugar levels, or hyperglycemia, can manifest through various symptoms. These include frequent urination, increased thirst, blurred vision, fatigue, headache, nausea, vomiting, shortness of breath, and abdominal pain. Fruity-smelling breath, dry mouth, and confusion may also occur, especially if hyperglycemia is left untreated.
Specific symptoms:
Frequent urination and excessive thirst: High blood glucose causes the kidneys to work harder to filter excess sugar, leading to increased urine production and, consequently, thirst.
Blurred vision: Hyperglycemia can affect the blood vessels in the eye, causing blurred vision.
Fatigue and weakness:
The body cannot use glucose efficiently as an energy source, which can lead to feelings of tiredness and weakness.
