The eyes can reveal high blood sugar levels if they have this symptom

Eye health not only reflects the quality of vision, but also It can be an early sign of systemic diseases such as diabetes. In fact, the eyes may show one of the first physical signs of high blood glucose levels. Recognizing this symptom early can be key to early diagnosis and avoiding further complications.

What eye symptom may indicate high blood sugar?

One of the most common symptoms that can alert you to high blood sugar is blurred vision. This visual problem can occur suddenly or gradually, and it affects both people who have already been diagnosed with diabetes and those who are unaware they have the condition.

Blurry vision occurs when high glucose levels cause the lens of the eye to swell, changing its shape and making it difficult to focus. In many cases, this effect is reversible if blood glucose levels are stabilized, but if left untreated, it can lead to more serious eye conditions.

Why does high blood sugar affect the eyes?

Excess glucose in the bloodstream damages the body's small blood vessels, including those in the eye. This damage can lead to:

• Diabetic retinopathy: Damage to the blood vessels of the retina that, in advanced stages, can cause vision loss.
• Macular edema: Swelling in a part of the retina that can also distort vision.
• Cataracts: Premature appearance of opacity in the lens.
• Glaucoma: Increased eye pressure that can damage the optic nerve.

What other visual signs can accompany hyperglycemia?

In addition to blurred vision, other visual symptoms that may be associated with high glucose levels include:

• Frequent changes in lens prescription
• Dry or irritated eyes
• Sensation of having "floaters" (spots or floating spots)
• Difficulty seeing at night

When to see a doctor?

If a person experiences sudden blurred vision without an apparent cause, especially if they also experience symptoms such as excessive thirst, frequent urination, or constant fatigue, it is advisable to consult a healthcare professional immediately. A blood test can confirm whether glucose levels are elevated.

Prevention and control

To prevent the effects of hyperglycemia on the eyes it is essential:

• Regularly monitor glucose levels if you are at risk for or diagnosed with diabetes.
• Have regular eye exams
• Maintain a balanced diet and control the consumption of simple sugars
• Exercise regularly
