My mom has low sodium levels with many of the symptoms listed. I am bringing her back to the dr. on Thursday. I thought I would do a little research. MY mom is extremely inactive. She weighs 255 and has had many behavioral changes. She doesn't eat the same, doesn't care how she looks, watches tv all day and needs assistance with bathing and dressing. She is 81 years old. She is on a diuretic with her hbp pill. We all just thought this was some dementia and she was giving up but maybe this is out of her control. Its very frustrating to watch her sit in a chair all day when my dad is 82 and still runs a multi-million dollar business. Do you have any advice for me?
