Which of the following is NOT a factor that causes urinary incontinence?

A healthy diet is not a contributing factor to urinary incontinence. Instead, it typically plays a supportive role in maintaining overall health, including the health of the urinary system. A balanced diet can contribute to normal bladder function and can help manage weight, which is important since obesity can be a risk factor for urinary incontinence.

In contrast, neurological disorders can directly impact the nerves that control the bladder, leading to incontinence. Prostate issues, particularly in men, can cause urinary obstruction or irritation, resulting in incontinence symptoms. Bladder infections can lead to inflammation and irritation, which may also result in involuntary leakage of urine. Therefore, while the other factors mentioned can contribute to urinary incontinence, a healthy diet does not have that effect.
