Suggest Medication To Improve The Appetite

Hi, my grandmother is 90 years old and she has suffered with dementia for the past eight or nine months. My uncle is her caregiver and he abruptly removed her from her condo as a result of a doctor visit where the doctor told him that she should not live alone. He did not realize that she was on medication for a thyroid condition and had not given it to her in six months. She loss over forty pounds. The problem that we have now is that she is taking her thyroid medicine, but she refuses to eat. She was recently hospitalized for not eating and the doctor recommended either a feeding tube or a blood transfusion due to her being an anemic. My quesiton is how do I get my grandmother to eat? She is back home but she has bed sores and soreness of her back because she was in the hospital for almost three weeks.
