<s>[INST] hi i recentley had my 7 years old sons lymph node checkd on neck and he said do you kbow he has anemia? i didnt but there special doctor i see didnt say what i should do and my son is very tired at times an his eyes hurt when tired? please could you advise many thanks [/INST] Hi.... I understand your concern. Anemia is a very simple problem, but at the same time, if it is only isolated anemia the most common reason is Iron deficiency. As a physician has recently checked your son and told that it is only an isolated anemia, and he is also symptomatic - like easy navigability, I suggest you use iron supplements at 3 mg per kg per day in 1 of 2 divided doses. But this is a prescription Chat Doctor.  I suggest that you get back to your sons' pediatrician regarding this. He will be requiring iron supplements for 3 months consistently. Regards -  </s>
