I take care of my 93 year old mother who has alzheimers and cannot move most of her body. Once she reached this stage, she started getting bedsores and we began a routine of shifting her in the bed every few hours, sometimes every 2 hours. I discovered a couple of things that make a difference. First, to cure a bedsore, the best thing is honey, Manukka honey if you can get it. The odd thing was that the two jars of it I bought, both the same brand but one with twice the "power" rating as the other were reversed in effect, I mean the lower power one cured faster than the one that was twice as expensive. (Note that I read that New Zealand produces a lot less Manukka honey than it sells -- IE, it is not all the 'real thing, ' so be careful.)
OK, best is to prevent bedsores in the first place. The thing I discovered first was zinc picolinate. Eight 25 mg tablets a day (crushed because of swallowing issues). That made her skin stronger and stopped the bedsores. This worked for about a year, but meanwhile her overall condition worsened
and she could no longer chew and eat regular food (or drink water) without choking. Her diet became very restricted and good nutrition became a problem (she has had only applesauce to "drink" for almost a year now). This is when we had to really move her body every two hours or pre-bedsore areas would form, even though I increased the zinc picolinate to 12 or more pills per day. But recently I read that 2500 IU of d-alpha tocopherol vitamin E is good for people with alzheimers, and then I discovered after giving her that for a couple of weeks that her skin no longer is forming those pre-bedsore blisters, and her skin seems stronger and not as thin.
So I thought I would try to pass on this important information in case it might help others.
