👉 Fainting is a medical condition in which a person's heart rate drops too quickly to meet their body's needs for oxygen. This can happen when a person is very tired or feeling unwell, and they cannot keep up with their breathing. Fainting can cause problems like shortness of breath, nausea, dizziness, and loss of consciousness.
There are several causes of fainting in children and adults, including:
- Hyperventilation (when the child's heart rate drops too quickly)
