The first thing to do is to find the cause of the head falling to the ground and dizziness. First, severe anemia, because hemoglobin has the ability to carry oxygen, and when anemia occurs, oxygen cannot be supplied to the mind, so it causes transient dizziness, nausea, vomiting, and falling to the ground. Second, dizziness and falling to the ground may be caused by insufficient blood supply to the narrowed cerebral blood vessels, or bleeding caused by cerebrovascular disease. In this case, first of all, routine blood tests should be done to exclude anemia, and CT of the head should be performed to see if there is any infarction or bleeding. In addition, we can also check the blood vessels of the head and neck to see if there is any narrowing of the blood vessels, and treat the cause of the disease.
