In fact, from the perspective of a hematologist, iron-deficiency anemia is the easiest disease to treat among blood system diseases, or it is not worth treating at all. Why is there suspense in the treatment of other diseases, such as twists and turns or ineffectiveness, but the treatment of iron deficiency anemia is always smooth sailing, without strong winds, waves and... heavy rains.
But the clinic is always full of uncertainty. One of my patients was checked for low serum ferritin, low serum iron, low hemoglobin, and other normal. He usually took iron for treatment, and there was no stomach pain, but hemoglobin continued to not rise. I was puzzled. His gastrointestinal absorption is good, and he has no obvious bleeding symptoms. Why can't he make up? I asked him about his medical history and comorbidities in detail. The patient hesitated and vomited, and finally told the truth. He had hemorrhoids and he bleeds in his stool every day. But because it is not easy to find, he can't estimate the specific amount of bleeding, but it seems to be bleeding a lot. This patient later had hemorrhoid surgery. One month after the operation, he took iron again and his blood picture returned to normal. Therefore, if there is no gastrointestinal absorption problem with a well-diagnosed iron deficiency anemia, it is more common to have gastrointestinal bleeding, hemorrhoid bleeding or menstrual blood loss.
In fact, although iron deficiency anemia is a blood system disease, it is actually a manifestation or part of the symptom group of many diseases, such as hemorrhoids and gastrointestinal bleeding. He can always find the trace of the original disease and needs to treat the original disease to finally cure iron deficiency anemia.
Finally, it needs to be emphasized that the iron supplementation cycle for iron deficiency anemia is 6 months. If the time is too short, it is easy to relapse, so you need to insist on taking it for a while.
