Doctor my mother,46, has IDA and vit B12 deficiency. Her haemoglobin was 8, iron level was 13 ug/dl, tibc was 470, and vitamin B12 was 112 pg/ml. She has all the symptoms of anaemia like shortness of breath, headaches, dizziness and one of them is her short term memory is getting poor. She started taking Vit B12 injections on 20 March, last month. How many months will it take for her memory to get better? Please tell us doctor. I'm scared she will forget everything slowly.
