What is venous stasis in the head and why it occurs

In the brain's blood circulates differently than in other organs. Blood arriving from the arteries, flows into the capillaries gives oxygen and other important substances to the surrounding tissues and enters the cerebral veins, which open into the cranial cavity to the venous sinuses (sinuses).

These sinuses are formed through bone tissue of the skull and the surface of the brain, but because their volume can't change. However, normal blood enters therein substantially less than they are able to accommodate. For this reason, their primary function is the prevention of venous stasis in cases of emergency, when the brain receives more blood than usual.

In addition to the venous sinuses, pressure regulation in the brain and produce vessels that are responsive to any changes in blood pressure. For example, when the brain receives a large amount of blood receptors on the surface of blood vessels send him a signal that gives "order" to enlarge the lumen of the vein. This improves venous outflow and decreasing pressure.

However, the human body is not always able so well to adapt to these changes in internal conditions. In some cases, venous congestion in the brain may occur due to the fact that the operation of the above receptors is impaired. In addition, there are many other causes of impaired venous outflow.

So light violations appear in the supine position without a pillow, when physical tension, while squeezing the collar of the neck. In turn, severe violations can occur when different diseases associated with neoplasms, cardiovascular system injuries of the neck and head and even with the absence of nasal breathing.

Venous congestion in the head: symptoms, diagnosis and treatment

Symptoms of venous congestion are frequent headaches, dizziness. Moreover, pain is able to increase when performing the various active operations, when changing external conditions (atmospheric pressure, temperature). In severe cases, may experience blackouts, fainting spells, epileptiform seizures, impaired mental functions. Externally, the disease may be manifested by redness, swelling, cyanosis of the face.

Because of such features of venous congestion in the head very rarely is a primary disease. Generally, it represents any comorbidities. And because the diagnosis is important to determine which kind of pathology underlies this problem. This will allow the patient the right treatment. To diagnose venous congestion in the brain most often used venography or x-rays of the skull.

In addition, it is necessary to consider external factors that may cause venous stasis. Thus, treatment should be aimed at dealing with the pathology that caused the stagnation. However, to facilitate the patient's condition, you can use different tools that allow you to restore the normal blood flow.

To get rid of dizziness and learn how sustainable equilibrium, it is useful to do special exercises. Before bed required an evening walk at least 40 minutes. It is also important to eat right, reducing salt intake and avoiding spicy, smoked and fried foods, strong tea and coffee.

At night it is useful to drink a Cup of warm milk with honey. Edema allows you to take oatmeal, boiled in water without adding salt and sugar.
