Dizziness in children with low blood pressure is caused by lack of oxygen in the brain, malnutrition, insufficient body fluids and high blood loss.
1. Lack of oxygen in the brain: when children’s blood pressure is low, the blood flow to the brain will be insufficient, and the brain will become dysfunctional due to ischemia and lack of oxygen, and the symptom of dizziness will appear.
2. Malnutrition: some children’s nutritional status is relatively poor, the body is in a state of severe malnutrition and triggered by low blood pressure, so that the low perfusion of the nervous system will cause dizziness.
3. Insufficient body fluids: children lose a lot of water due to the heat factor, or lose too much body fluids in severe diarrhea or vomiting, resulting in insufficient effective blood volume triggering low blood pressure, which will show the symptoms of dizziness.
4. Loss of blood: children due to trauma resulting in rupture of blood vessels or bleeding in the upper gastrointestinal tract, can not stop bleeding and replenish blood volume in a timely manner, the sudden drop in circulating blood volume caused by a decrease in systemic blood volume, the emergence of low blood pressure after dizziness.
Children’s low blood pressure dizziness causes more, it is recommended that timely medical treatment.
