Venous congestion in the head - how to live with it

Violation of venous outflow of the head in our time is not uncommon. Unsurprisingly, most people spend a lot of time in a sitting position, often bending their heads over any document, book or notebook. All this, of course, has an effect on the venous outflow in the head.

But before talking about what constitutes a venous congestion and how to deal with it, you need to talk about how the system of blood supply in the brain is arranged. In this part of the body, the blood circulates somewhat differently than in other organs. The blood that came from their arteries, which got into the capillaries and gave oxygen to the surrounding tissues and other necessary substances, enters the brain veins that open into the venous sinuses (sinuses) in the cavity of the skull. These sinuses are formed by the skull bone tissue and the surface of the brain, so their volume can not be changed. Nevertheless, the blood in them is normally received much less than they can accommodate, so their function is primarily to prevent venous congestion in emergency cases, when blood enters the brain more than usual.

In addition to these devices, the regulation of cerebral pressure is also carried out by vessels that react sensitively to any change in blood pressure. For example, when a lot of blood enters the brain, special receptors on the surface of the vessels send a signal to the brain, which commands to expand the lumen of the veins, which improves venous outflow and reduces pressure.

But not always the body can adapt so well to changes in internal conditions. Occasionally, venous congestion may occur due to the fact that the work of the above-described receptors is disrupted. In addition, there are many other causes of venous outflow: light disorders occur with physical stress, in a lying position without a pillow, when the neck is squeezed by the collar. Severe disorders occur in a variety of diseases, one way or another associated with the cardiovascular system, neoplasms, head and neck injuries and even in the absence of nasal breathing.

Symptoms of venous stasis are frequent headaches, dizziness. Moreover, pain can become stronger when performing active actions, changing external conditions (temperature, atmospheric pressure). In severe cases, there may be syncope, impairment of mental functions, darkening in the eyes, epileptiform seizures. Outwardly, the disease can be manifested by puffiness, blueness of the face, reddening of the eyes.

Because of this feature, venous congestion in the head is almost never a primary disease, and often represents a concomitant pathology. Therefore, it is important in diagnosis to determine which pathology lies at the root of this problem, so that the right treatment can be prescribed. In addition, it is important to consider external factors that can cause venous congestion. Treatment, therefore, is aimed at combating pathology, which can cause stagnation. Nevertheless, to ease the patient's condition, various means can be used that restore normal blood flow.
