Which organs of the body are primarily affected by diabetes?

Diabetes primarily affects various organs in the body due to its impact on blood sugar levels and overall metabolic processes. The correct selection highlights the eyes, kidneys, heart, and feet as the major organs impacted by diabetes.

In relation to the eyes, diabetes can lead to diabetic retinopathy, where high blood sugar damages the retina's blood vessels, potentially resulting in vision loss. The kidneys are also significantly affected; diabetic nephropathy is a serious complication where excess blood sugar causes damage to the kidneys' filtering system. Heart health is crucial in diabetes management, as individuals with diabetes are at an increased risk for cardiovascular diseases due to factors like high blood pressure and cholesterol levels. Finally, the feet can suffer from complications such as peripheral neuropathy and poor circulation, which can lead to infections, ulcers, and in severe cases, amputations.

Each of the other choices includes some organs affected by diabetes, but they either omit key organs like the eyes or kidneys or include organs that are less directly associated with the complications of diabetes, such as teeth or lungs. Thus, the selection emphasizing the eyes, kidneys, heart, and feet accurately represents the primary systems impacted by diabetes complications.
