In 11-year-old children, frequent dizziness is mainly due to the following aspects: 1. It may be caused by anemia. If the child is a picky eater, it can lead to varying degrees of anemia and dizziness. 2. Some children may not eat on time and have low blood sugar, which can lead to dizziness, accompanied by panic, hunger, and cold sweats. 3. If the dizziness is often heavy, it may be caused by diseases that increase intracranial pressure, such as intracranial tumors and intracranial occupations.
