Thanks for your response.
Since her colon resection, she's had diarrhea (every time she eats fruits and vegetables). Her family doctor has her on 2 iron pills a day, plus 12 other pills related to her other conditions (heart, diabetes, etc.).
Just because her doctor is skeptical that the rubber band ligation will work...it is well worth trying. It's non-invasive and maybe her only hope. But I'm big on getting more than one opinion, and you may want to do this. Your mom has suffered a lot and the doctor need to try something to help her. I wish you and your mom all the best.
Welcome to the gastroenterology community! I would recommend that you get a second opinion about this. Also, is she is having any problems with constipation, this can make the hemmorhoids worse, so I would recommend talking to your doctor about treating this.
