A more accurate way to determine whether a child has anemia is to go to the hospital for routine blood tests, which will include red blood cell count and hemoglobin. If the red blood cell count or hemoglobin level is significantly lower than normal, it means that the child is likely to have anemia and can also roughly determine which kind of anemia the child belongs to. In addition to blood count, parents can also use the following aspects to assist in judgment: 1. Activity level: usually the child will have significantly less activity, will feel weak in daily life, and will feel tired with brief activities; 2. Digestive system symptoms: the child will have a significantly decreased appetite, often feel gastrointestinal discomfort, and some children will also experience nausea and vomiting; 3. Central nervous system symptoms: the child will have Headache and dizziness, learning ability will also be reduced, memory will be significantly reduced, usually easily irritable and restless, and some children will also affect their heart and feel panic; 4. Physical signs: the child’s lips, face and skin under the nails will become paler, and due to the skin color, there will be a similar yellowing performance after anemia, and the spirit will be more depressed. If a child is found to be anemic, or if the blood test shows lower than normal values such as hemoglobin, further tests should be performed to determine the type of anemia, and then targeted treatment should be given.
