A chance to fall is a chance to break. As you get older, and particularly if you have any number of chronic (neurological) illnesses, you lose some ability to recover from that unexpected obstacle or to navigate that uneven ground.
There are many factors that can contribute to falls. So there are many approaches you can take to limit your risk. These include making some changes to your (home) environment, using devices such as a cane or walker (if appropriate), and possibly adjusting medications.
In the home, make sure that handrails on the stairs are secure and in good repair. Rugs should be fastened to the floor, not loose. Make sure lighting through the house (including hallways) is adequate, with as few dark spots and as little glare as practical. Install grab bars in the shower and by the toilet. Keep soap buildup off the bottom of the tub or shower. Use non-slip strips in the bath or shower.
You may have medications prescribed by more than one doctor. Many medications can make you off balance or drowsy, and they might interact. Be sure all of your doctors have an up to date list of all of your medications. If you suspect your balance or alertness is affected, bring this up with each of your doctors so you can search for problem medications or combinations.
Contemplating the use of a cane, walker, or wheelchair may be a big step for some, and not so much of a big deal for others. This decision is made in consultation with your doctor, often with advice from other professionals such as physical therapists.
