Her hemoglobin level is low(9.5-10.5). Is it a case of iron deficiency?what I have to do? [/INST] Hi, The hemoglobin level of your daughter is lower than normal. This is the cause of fatigue. This is most probably an iron deficiency anemia. She needs iron supplement for a month and after one month she should repeat the hemoglobin level test. As for the constipation and fissure, she should increase the fiber content of her diet (oranges, bran for example). Or she could take bran tablets if she doesn't like to eat foods with high fiber content. Lactulose syrup may also help relieve constipation, when the constipation is relieved it will allow the fissure to heal. She should apply an antibiotic cream on the fissure 3 times daily after washing her anus and Chat Doctor.  Mouth ulcers are due to vitamin deficiency. She should take a multivitamin supplement. Hope I have answered your query. Let me know if I can assist you further.  </s>
