Diabetes is a disease that affects millions of people and, when left uncontrolled, can cause serious damage to different parts of the body. Although they are often overlooked, some changes in vision can indicate that blood glucose levels are out of control.
Diabetes can affect vision
Uncontrolled diabetes can cause progressive damage to the blood vessels in the retina, a structure located at the back of the eye that captures images and sends them to the brain.

This damage occurs because high blood glucose levels weaken and make blood vessels more prone to leaking or even becoming blocked. As a result, diabetic retinopathy can develop, a serious complication that, if left untreated, can lead to partial or total vision loss.
In addition, excess glucose can directly affect the optic nerve, which is responsible for transmitting visual stimuli to the brain. This can result in symptoms such as blurred, cloudy or darkened vision, making it difficult to see images clearly and impairing the ability to see clearly. These changes can occur temporarily or progressively, depending on the degree of uncontrolled diabetes.
What are the eye symptoms that may indicate diabetes?
Blurred or unfocused vision: This can be one of the first symptoms of uncontrolled diabetes, indicating fluctuations in glucose levels. It is as if the vision is blurred, cloudy, double or darkened.
Difficulty seeing at night: vision problems in low-light environments are common among diabetics. Dark spots or spots: these symptoms may be related to hemorrhage in the retinal vessels.

How can these complications be prevented?
Controlling blood glucose levels is the main way to prevent eye problems.
Recommended actions include:
Monitorar regularmente os níveis de glicose no sangue;
Adotar uma alimentação equilibrada, rica em nutrientes e pobre em açúcar; Praticar atividades físicas regularmente; Realizar exames oftalmológicos periódicos para identificar sinais precoces de retinopatia diabética.
Any changes in vision should be investigated as soon as possible, especially if there is a history of diabetes or symptoms that may indicate the disease. An ophthalmologist can perform tests and recommend appropriate treatment.
