Hello Nancy, I wonder if you are aware that falls can be the #1 reason us seniors lose our independence? So it is very important that you find out why this is happening to you before you get injured.
Low blood pressure on rising is very common, and getting up slowly is a good way to stay safe. That's why, if you are in the hospital, they will have sit on the edge of the bed first, wait a short time, then stand up carefully.
If the falls have happened more than once, PLEASE contact your doctor now for a complete evaluation. It may be that your medications need to be reduced or changed. This often happens as we get older because the way our liver metabolizes medication changes.
