I feel blood rushing up my head

The feeling of blood rushing upwards in the head is a phenomenon of cerebral congestion. In many cases, if a person feels blood rushing up to the head, it may be because he suddenly stands up while squatting, or because he suddenly sits up while lying down. These situations will cause blood to rush to the brain suddenly, because the body's original state is suddenly changed, and the intense exercise causes blood to circulate suddenly faster and rush to the brain. Let’s take a look at what’s going on.

Insufficient blood supply to the cerebral arteries causes insufficient blood perfusion to the brain tissue, resulting in swelling of the cerebral blood vessels.

The brain is supplied with blood from two arterial systems: the internal carotid system and the vertebrobasilar system

The internal carotid artery is an artery that originates from the common carotid artery, rises vertically to the base of the skull, enters the cranial cavity through the carotid canal, and branches out to the visual organs and brain. The main branches of the internal carotid artery include the anterior cerebral artery, middle cerebral artery, anterior choroid plexus artery, posterior communicating artery, and ophthalmic artery.

The vertebral basilar artery is an important blood supply artery to the brain. The vertebral artery has one branch on each side, which passes through the transverse foramen on both sides of the cervical vertebrae and goes upward into the skull. The two blood vessels merge into one branch in the brain called the basilar artery. Many small blood vessels of varying sizes extend from the vertebral artery and basilar artery to supply the occipital lobe, cerebellum, brain stem, thalamus and inner ear of the human brain. The vertebral arteries and the basilar arteries and their branches are collectively called the vertebrobasilar system.

(1) Distribution of vertebral arteries

Many small blood vessels of varying sizes extend from the vertebral artery and basilar artery to supply the occipital lobe, cerebellum, brain stem, thalamus and inner ear of the human brain. The vertebral arteries and the basilar arteries and their branches are collectively called the vertebrobasilar system.

(2) Vertebral artery blood flow

Normally, the blood flow of bilateral vertebral arteries is 200 ml/min, and the right side is 130.47±56.10 ml/min.

The left side was 164.21±63.54ml/min, and the total blood flow on both sides was 293.70±80.74ml/min.

It is equivalent to 1/5 of the total cerebral blood flow. When various causes cause the blood flow of the vertebral basilar artery system to drop to a certain extent,

Corresponding symptoms of cerebral ischemia appear, which generally do not exceed 24 hours, but may recur. It is medically known as transient ischemic attack of the vertebral basilar artery system, abbreviated as "VBI". Some patients have mild symptoms but they do not improve within 24 hours, which is also known as vertebral basilar artery system insufficiency.

It is recommended to pay attention to rest, avoid fatigue, and promote brain recovery drug treatment, such as alkaline fibroblast growth factor, Nootropics, and enteric-coated aspirin tablets to prevent platelet aggregation. Pay attention to a light diet and drink plenty of water.
