Iron Deficiency Anemia

Emily is a 26-year-old female presenting with fatigue and pallor for 2 months. For the past two months I've been feeling increasingly exhausted. It's not like normal tiredness — I can barely get through my work day and by the evening I'm completely wiped out. I used to go to the gym four or five times a week but now I can barely manage a light walk without feeling winded. Your task is to take a focused history from this patient.
