How to cure an umbilical hernia in a child What are edema There are many people who do not rumor to know what an edema is. This is a pathological phenomenon, which is the appearance of a collection of water in any cavity, part of the body or tissue. In the normal state, the device regulates the inflow and outflow of aqueous media in the tissues, and they are usually similar. In this case, stagnation does not occur, and the substances formed as a result of metabolic processes in the cells dissolve into the water and are eliminated from the body, and the necessary substances enter the tissues.

Species of edema

Depending on the prerequisite of the onset of systematization of edema, it is assumed that they are divided for certain species. Clinicians distinguish 5 main types of water accumulation in the body that appear to be different abnormalities and diseases.

Hydrodynamic edema

It occurs in this case, if the blood pressure in the vascular bed soon grows. The causes of this swelling are: hypertensive pain; symptomatic hypertension; vein thrombosis; compression of vessels with a tumor or scar; thrombophlebitis of the lower extremities; heart failure; polycythemia; гипергидратация; pregnancy. The design of this phenomenon is that the blood pressure for the wall of the capillaries leads to sweat of its watery part through the walls and congestion between the cells. A gradual increase in interstitial edema leads to an increase in the volume of water and within the cells.

Lymphogenous edema

An effusion through the lymphatic small vessels occurs either by blocking them or by increasing the hydrodynamic pressure in them. Such hypertension is determined by the following conditions: compression by a tumor, metastases or parasites; lymphogranulomatosis; lymphoma or lymphosarcoma; a decrease in protein to be fasting or a violation of albumin synthesis; nephrotic syndrome; the highest burden in the veins.In fact, lymphogenous edema appears as a result of two effects - hydrodynamic and oncotic.

Oncotic edema

There may be a decrease in osmotic pressure due to a decrease in the volume of proteins in the blood. This happens in accordance with three main reasons: the lack of the supply of protein to the device, unnecessary removal and lowering of its internal production. Strict order, hunger or impairment of the exocrine function of the pancreas leads to hypoalbuminemia. Violation of the production of proteins in the liver can be the development of cirrhosis if hepatocytes are replaced by a connective tissue and cease to perform the bait function. To be given the disease there are significant edema, caused not only by the indicated prerequisite, but also by increased pressure in the portal vein. Proteins are excreted to be a violation of the multifunctional activity of the kidneys, to be wide burns and exudative enteropathy.

Osmotic edema

Such future edema occurs in 2 cases: to decrease the osmolarity of the blood or to increase the osmolarity of water in the intercellular space. Such a phenomenon is noted to be such deviations, like: гипергидратация; impaired kidney function; excess elimination of sodium.Water ceases to linger in the capillaries and begins to do in the intercellular space, and later in the cells. The cause of swelling in most cases is noted to be pregnancy and epileptic seizures.

Membraneous edema

In this case, the release of the watery part of the blood can be a violation of the permeability of the capillary wall. Such a disorder develops as a result of acidosis (an increase in the acidity of the blood) being a fasting or a sweet diabetes. The same design occurs during the appearance of the focus of inflammation, if the action of hyaluronidase begins to multiply. This structure accompanies angioedema, generalized release of water to be inflammatory processes in the kidneys or pancreas.

Division by Origin

There is a systematization of edemas according to their origin: Inflammatory. To be such an option in most cases, puffiness is local and can take place for any part of the body where the inflammatory action takes place. Allergic. Its design is to impair vascular permeability as a result of increased histamine production. Toxic. Violation of the vascular wall occurs with exposure to harmful substances. Can move boundless temper. The Alcoholic. Refers to osmotic edema, because lowering the protein in the blood increases the passage of water through the microcirculatory bed into the intercellular space. Lymphatic. It all corresponds to lymphatic
