Urinary incontinence is a prevalent and costly condition that affects approximately 38% of older community-dwelling women (age>60 years). Incontinence predisposes patients to other health problems, contributes to depression and social isolation, is a significant source of dependency among the elderly, and is widely cited as a factor in nursing home admissions. Sarcopenia is age-related and is characterized by loss of muscle mass, strength and endurance. There is not only a decrease in the number of muscle fibers, but also atrophy in the remaining ones. Several studies indicate glutamine supplementations lead to better muscle performance by stimulate muscle producing in extremities. Similarly, we assume glutamine supplementation could increase pelvic muscle mass and improve the pelvic floor strength. From this point, using glutamine supplementation may effect positively on stress, urge or mixed incontinence, and pelvic prolapse.
