What complication can arise from poorly managed diabetes?

Poorly managed diabetes can lead to a range of complications, one of which is vision problems. This is primarily due to high blood sugar levels that can damage the blood vessels in the retina, leading to diabetic retinopathy. Diabetic retinopathy can eventually result in vision loss if not managed effectively. Additionally, diabetes can increase the risk of cataracts and glaucoma, further contributing to vision-related issues.

Other complications from poorly managed diabetes may include nerve damage, cardiovascular disease, and kidney problems, but the focus here is on how it specifically impacts vision. In contrast, improvements in energy levels, immune response, and kidney function are generally not associated with poorly managed diabetes; rather, they are outcomes of well-managed blood glucose levels and overall healthy lifestyle practices.
