Final answer:
Urge urinary incontinence, also known as overactive bladder, is influenced by alcohol and caffeine. These substances increase urine output and can aggravate symptoms of involuntary urine leakage due to their diuretic effects.
Step-by-step explanation:
The type of incontinence that is influenced by alcohol and caffeine is primarily urge urinary incontinence, also known as an overactive bladder. Alcohol consumption affects the excretory system by inhibiting the hormone ADH (antidiuretic hormone), which typically helps the body retain water by making the collecting ducts in the kidneys permeable to water. Instead, less water is reabsorbed, leading to an increase in urine volume and frequency of urination. Similarly, caffeine is a diuretic, which means it can lead to increased urine output, thereby potentially exacerbating symptoms of incontinence.
Both substances can lead to an 'overactive bladder', causing the bladder to empty unexpectedly and without sufficient warning, which may result in leakage of large amounts of urine. Individuals with this type of incontinence experience a sudden, intense urge to urinate followed by an involuntary loss of urine. Management of urge incontinence may include lifestyle changes such as reducing the intake of diuretics like caffeine and alcohol, as well as medication and pelvic floor exercises for some.
