Question
What are the symptoms of iron deficiency anemia?
Answer
The symptoms of iron deficiency anemia should be considered from two aspects. On one hand, there are changes related to the primary disease, such as gastrointestinal diseases where patients may experience changes related to the gastrointestinal system, such as gastric or colorectal cancer. Some patients may experience iron deficiency due to repeated bleeding from conditions like hemorrhoids. Women may exhibit these symptoms due to menstrual issues. On the other hand, there are the symptoms specific to iron deficiency anemia itself, which is a change in anemia, with increased iron metabolism that may affect various systems in the body, such as the nervous system, potentially leading to symptoms like dizziness, headaches, and lack of concentration.
