Which condition is NOT related to the diseases of the excretory system?

Diabetes is a metabolic condition primarily characterized by an impairment in the body's ability to regulate blood sugar levels, rather than a direct disease of the excretory system. While diabetes can lead to secondary complications that may affect the kidneys, such as diabetic nephropathy, it is not inherently classified as a disease of the excretory system itself.

In contrast, urinary tract infections (UTIs), prostatitis, and glomerular disorders are directly associated with how the body manages waste elimination and fluid balance. UTIs are infections that can occur anywhere along the urinary tract, prostatitis refers to inflammation of the prostate gland which can affect urination and overall urinary health, and glomerular disorders involve damage to the glomeruli in the kidneys, directly impacting filtration and waste excretion. These three conditions are closely linked to the function and health of the excretory system, whereas diabetes is more focused on metabolic processes.
