My mother had a appointment with her new doctor today. When they weighed her, she was between 68-70 pounds, scale was fluctuating. She was 89.6 pounds on May 22nd when she was discharged from the physical therapy live-in facility. She eats 3 meals a day and has snacks in between meals. Her blood work showed she has an elevated platelet count of 551. Does anyone know what could cause this weight loss and how can I stop it? Can a person be this thin without her vital organs being effected? We are scheduling an MRI. The new doctor questioned the prior doctors diagnosis of dementia as well. Any advice would be most welcomed.
