Falls among older adults is the leading cause of fatal and non fatal injuries. One in three older adults fall yearly. However not all are reported to a doctor. Falls cause over 20,000 fatalities a year. They are also responsible for almost half traumatic brain injury among older adults. They also cause significant injury due to broken bones.
Exercise and nutrition (including calcium and vitamin D) can help prevent falls. Also being aware, and perhaps decluttering your home to prevent hazards. Also adding grab bars, by the tub, by the toilet etc can be helpful.
Out family has experience with falls. Mom has fallen several times. She has broken her neck and her hip, and banged up her face very badly on occasion.
