How does diabetes mellitus contribute to urinary disorders?

Diabetes mellitus can significantly contribute to urinary disorders primarily through nerve damage and bladder dysfunction. This condition often leads to diabetic neuropathy, which affects the autonomic nervous system responsible for bladder control. Damage to the nerves that innervate the bladder can disrupt normal bladder function, leading to symptoms such as urinary incontinence, urgency, and difficulty emptying the bladder completely.

Additionally, as the bladder's ability to contract and sense fullness diminishes, the risk of urinary retention increases, which can further complicate urinary health. Over time, these nerve dysfunctions can result in complications such as urinary tract infections and increased risk of kidney damage. Understanding this connection is critical for managing urinary symptoms in individuals with diabetes mellitus effectively.

The other choices do not fully capture the primary mechanism through which diabetes affects urinary function. Excessive fluid intake is not a direct consequence of diabetes and does not inherently lead to disorders of micturition. Increased muscle mass is unrelated to urinary function in this context, and while diabetes can correlate with high blood pressure, it is not the primary pathway through which urinary disorders arise in this condition.
