What causes edema on the legs

Edema is the pathological displacement of fluid from thevessels with subsequent accumulation in surrounding tissues. Edema can be common (covering almost the entire surface of the body) and local, or peripheral (located on the limbs). In the first case, edema is associated with a violation in the work of internal organs and systems, and in the second - with hormonal disorders (pregnancy), vascular pathologies, trauma or exposure to damaging factors (temperature, chemicals, poisons). The most frequent location of peripheral edema is the feet.

Swelling of the feet appear as a result of increasedhydrostatic pressure in the veins, which contributes to "squeezing" the fluid into the intercellular space. Therefore, to recognize the swelling is very simple, you just need to press the tumor with your finger. To the touch, it should be soft and painless, perhaps a feeling of movement of the liquid in the place of touch. If the finger is removed, then on the pressure site for some time remains a noticeable fossa, which after a certain time interval is again filled with liquid. Also, the swelling of the legs is accompanied by a characteristic feeling of heaviness and inconvenience in the affected limb.

Swelling of the legs leads to a lot of discomfort, firstturn associated with the movement and putting on shoes. In addition, the enlarged limb becomes more tired, considerably loses its mobility and sensitivity. In some cases, swelling can lead to oozing ulcers and even phlegmon.

Swelling of the feet is a good reason forof concern. It is always a sign of the development of a serious disease, one way or another connected with the metabolism. Here is an incomplete list of the most common pathological conditions of the body, in which leg edema occurs: heart failure, kidney disorders, thrombophlebitis, varicose veins, metabolic disorders and "elephantiasis".

Also, swelling may occur with allergicstates, high physical activity and the impact of damaging factors of different nature. In addition, swelling of the feet may arise from improperly selected shoes. The appearance of edema in young people often speaks of vascular problems, in the elderly is a consequence of heart disease.

What should I do if my legs swelled?

In the first place - go to the hospital. Most patients do not even suspect the problem and bring it to a state of neglect. Therefore, self-treatment of edema of the legs is impractical - it will not give the proper effect, because to eliminate swelling, you must first eliminate the cause of their appearance. Any relief and "recovery" phenomenon is either temporary, or suggests that the disease has passed into a chronic course, without pronounced external manifestations.

  • First of all, you need to pay attention to shoes: it is possible that the too narrow upper part compresses the blood vessels and makes it difficult to drain blood.
  • If the patient takes medications at the time of onset of swelling, then he must undergo a series of allergic tests for compatibility with the drug.
  • If foot swelling occurs in the summer, then salt and water intake should be reduced.
  • Minor relief can be obtained by assuming a reclining position and raising the injured limb as high as possible.
