7-year-old children often say that dizziness may be related to regular sleep deprivation or may be caused by disease causes, such as iron deficiency anemia, chronic sinusitis, hypoglycemia, colds, vision problems, intracranial tumors, etc. It may also be accompanied by headache, sleepiness, and weakness. It is recommended to take children to the hospital as soon as possible to confirm the cause and treat the symptoms early to prevent delays.1. Insufficient sleep: 7-year-old children are in a period of rapid growth and development and need sufficient sleep time to maintain normal physical exertion during the day. If there is often a lack of sleep, resulting in the brain can not get sufficient rest, resulting in brain nerve dysfunction, resulting in cerebral vascular diastole, contraction dysfunction, which in turn causes brain cells ischemia, hypoxia, can cause regular dizziness in children. Attention should be paid to adjusting the work and rest schedule of 7-year-old children to ensure sufficient sleep every day, which will help to alleviate regular dizziness; 2. Iron deficiency anemia: because the blood of 7-year-old children has a reduced content of red blood cells, the ability of blood to carry oxygen is reduced, resulting in chronic lack of oxygen to the brain, which can cause regular dizziness, accompanied by pallor, weakness and other manifestations. Symptomatic application of iron dextran, ferrous lactate and other drugs to correct anemia, which is conducive to alleviating the above symptoms; 3, chronic sinusitis: 7-year-old children with increased nasal secretions, resulting in poor ventilation of the nose, thus causing brain hypoxia, can cause frequent dizziness, can also be accompanied by nasal congestion, runny nose and other manifestations. It can be treated by nasal irrigation with saline and anti-infection treatment with antibiotics such as amoxicillin and cefaclor, as well as local nasal drops such as fluticasone propionate nasal spray and ephedrine hydrochloride nasal drops; 4. It can also be accompanied by panic, fatigue, sweating and other manifestations. Children should strengthen their dietary nutrition and avoid picky eating and partial eating. When the hypoglycemic reaction attacks, you can eat some candy, bread, buns and other foods in time to help raise blood sugar to relieve the above symptoms; 5, cold: when 7-year-old children suffer from the flu, especially influenza, because the influenza virus invades the child’s head nerves, can cause frequent dizziness symptoms, but also accompanied by headache, nasal congestion, cough and other symptoms. Antiviral drugs such as oseltamivir phosphate can be applied, while symptomatic support treatment can be given. For example, for fever, drugs such as ibuprofen and acetaminophen can be used to reduce fever. For cough symptoms, drugs such as pediatric phlegm and cough granules can be applied to relieve them; 6. Vision problems: If a 7-year-old child has vision problems such as farsightedness and myopia, he or she is also prone to frequent dizziness, mainly caused by the involvement of the visual system. This is mainly caused by the involvement of the visual system. The dizziness should be corrected by optometry and glasses at a regular hospital in time to help relieve the dizziness; 7. Intracranial tumor: The increase in intracranial pressure due to the compression of local brain tissue by tumor can cause frequent dizziness in 7-year-old children, which can also be accompanied by severe headache and symptoms such as nausea and vomiting. When the intracranial pressure is increased, dehydrating drugs such as mannitol injection and glycerol fructose sodium chloride injection should be applied in time to lower the cranial pressure. For children who are eligible for surgery, they should be treated with early surgical removal of tumor.
