The hospital Dr dx her with hemoletic anemia. Said it is an autoimmune problem. They Don t know what is causing it. Can you tell me reasons why this could be happening. They have ruled our rx medications, travel, food, and environmental triggers.
<bot>: Hello, The body needs red blood cells to survive. They carry hemoglobin, a complex protein that contains iron molecules. These molecules carry oxygen from the lungs to the rest of the body. Some diseases and conditions can result in a low level of red blood cells.  There are many types of anemia, and there is no single cause. It can sometimes be difficult to pinpoint the exact cause. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
