Part one of my reply was so long I thought I would do this separately.
Most of the people here are recipients and would be better able to answer question about how your mom will fare. I met the woman I donated to the day before surgery so I can't give you too much back story. She was 60, had been on dialysis for almost 5 years and had acquired diabetes and gout along the way. She couldn't walk more than a block without resting and was only urinating once a day.
The kidney started working immediately and her gout disappeared quickly. She is able to manage her diabetes through diet now. She was walking around the day after surgery and left the hospital after 4 nights. She was able to walk the 5 blocks to our hotel. She had to stick around for about a month (she lives 5 hours from the hospital) for appointments.
She had some minor signs of rejection in the 1st year but has been able to drastically reduce hers meds since then and is not showing any signs of rejection. I think she still goes in for labs about once a month and to the doctor every 6 months.
We talk every week and don't go into much medical detail but she is doing well and decided to go back to work because she was getting bored! Since her surgery, we have gone to Mexico for her oldest daughter's wedding, she was at the hospital for the birth of her daughter in law and son's baby.and is helping plan her youngest daughter's wedding. She is very active and I love hearing about her adventures.
Organ donation is truly a miraculous thing and I'm so glad when someone can be a part of it.
