Swollen legs are ugly and unpleasant. In addition, in most cases, the appearance of edema indicates the presence of pathological changes in the body, although an absolutely healthy person is not immune from such a problem. Edema of the legs is experienced by both men and women, and for many expectant mothers, swollen legs become continuous torment, which disappears only after childbirth.
Why do edema form?
Edema is inherently a fluid that has accumulated where it should not. Why is this happening? Normally, the smallest capillaries take all the waste fluid from the intercellular space, and it is transported further along the venous bed. The ability of capillaries to perform their function is affected by the permeability of the vascular wall, blood pressure in the peripheral vessels, and the content of proteins and sodium in the blood. If something in this established mechanism gets stuck, the fluid stagnates and swelling forms. Causes of leg swelling various overheating protection mechanisms are activated. One of them is the expansion of peripheral vessels, as a result of which pressure drops in them, and microcirculatory processes are disrupted. This leads to the accumulation of water in the tissues. In the second half of pregnancy, since the hormones of the placenta contribute to the expansion of blood vessels and sodium retention in the body. After a long stay in a standing position, sitting in an uncomfortable position or with legs thrown back one on one. Because of this, the pressure in the veins increases, and they can not fully perform their function. When wearing uncomfortable shoes and love for high heels, when a lower load is placed on the lower extremities, which leads to disruption of normal microcirculation in the tissues. Leg swelling may be a sign many diseases and pathological conditions of the body: Inflammation and venous thrombosis. Heart diseases accompanied by heart failure. Kidney disease. Lymph congestion in the extremities. Thyroid diseases. Diabetes mellitus. Chi liver disease. Gestosis – a serious complication of pregnancy. Symptoms of swelling of the lower extremities. The first signs of fluid stagnation in the legs are small traces of gum socks on the legs, an uncomfortable feeling when walking in familiar and previously comfortable shoes. Later, swelling becomes noticeable by a change in the shape of the lower extremities.
Physiological edema on the legs appears at the end of the day, as well as after the above-described errors in eating or staying in extreme heat. In this case, swelling does not extend above the legs. Long rest in a horizontal position, as a rule, brings relief.
Pathological swelling of the legs appears at any time of the day, and it is not always possible to eliminate it by conventional non-pharmacological methods.
Each disease has its own characteristics of edema:
With varicose veins, edema on the legs can be asymmetric. Their appearance is accompanied by soreness and heaviness in the limbs. With thrombophlebitis, only the affected leg swells, while pain and burning along the inflamed vein are felt, as well as redness of the skin above it. With heart failure, both legs swell, with pressure on the swollen tibia there are pits that slowly disappear. Renal edema first appears on the eyes, later, if the disease progresses, the legs swell, while the skin of the limbs becomes very pale.
