age-related loss of muscle mass and strength is called
Sarcopenia Sarcopenia is the degenerative loss of skeletal muscle mass (0.5–1% loss per year after the age of 50), quality, and strength associated with aging.[1] Sarcopenia is a component of the frailty syndrome. It is often a component of cachexia. It can also exist independently of cachexia; whereas cachexia includes malaise and is secondary to an underlying pathosis (such as cancer), sarcopenia may occur in healthy people and does not necessarily include malaise. The term is from Greek σάρξ sarx, "flesh" and πενία penia, "poverty".
Urinary incontinence The most common types of urinary incontinence in women are stress urinary incontinence and urge urinary incontinence. Women with both problems have mixed urinary incontinence. After menopause, estrogen production decreases and in some women urethral tissue will demonstrate atrophy with the tissue of the urethra becoming weaker and thinner.[2] Stress urinary incontinence is caused by loss of support of the urethra which is usually a consequence of damage to pelvic support structures as a result of childbirth. It is characterized by leaking of small amounts of urine with activities which increase abdominal pressure such as coughing, sneezing and lifting. Additionally, frequent exercise in high-impact activities can cause athletic incontinence to develop. Urge urinary incontinence is caused by uninhibited contractions of the detrusor muscle . It is characterized by leaking of large amounts of urine in association with insufficient warning to get to the bathroom in time.
