Slight swelling of the legs
There are several causes of edema:
1. Increased permeability of the membrane of the vessels.
2. Reduction in the blood protein and electrolytes, which reduces the osmotic pressure and the fluid ceases to be retained in the vessels. All this is typical for kidney damage, when the protein passes into the urine and decreases its content in the blood, or when the liver is damaged, when protein synthesis is disrupted. It can also occur during fasting.
3. Violation of the valve veins: when the venous blood can not move at the right speed and in sufficient amount to the heart, it stagnates and excess water is simply pushed out of the vessels. This kind of edema is characteristic of varicose veins and explains the occurrence of edema in the lower parts of the body, where the blood is hardest to move upward.
4. Lymphatic edema is caused by the inflow of lymph to the site of the injury or occurs when the lymph vessels are damaged or removed. It is the lymphatic edema that most often occurs with injuries, infections and inflammation. Cellulite is also a problem caused by stagnation of lymph in the tissues.
5. Neurogenic edema occurs when nerve fibers are damaged, when the vessels receive incorrect information about the need to increase or decrease the permeability of the vascular wall.
6. Violation of the heart activity, when the rate of blood transfer is disturbed, the blood stagnates in the tissues and excess plasma is pushed out of the vessel.
Swelling as a result of illness
In addition, that edema is different in the mechanism of its origin, they differ and in place of localization. Such swelling is a consequence of a disease.
Kidney swelling most often appear on the face, accompanied by pallor of the skin. As a rule, these are loose edema, which for a long time retain a trace from depression. Appear in the morning and fall to the evening.
Cardiac edema is characteristic of the abdomen, sexualorgans and legs, can be accompanied by shortness of breath, cyanosis (cyanosis) of the lips, fingers of the feet and brushes, swelling of the cervical veins. By morning they can completely disappear, intensify towards evening.
With lesions of the veins, swelling on the legs, accompanied by pain in the legs, a feeling of heaviness in them, swelling of the veins of the lower extremities, redness of the feet, appear and increase throughout the day.
Hepatic swelling manifests as ascites (accumulationfluid in the abdominal cavity) and edema of the anterior abdominal wall. Accompanied by the appearance of vascular asterisks on the abdomen, itching and icterus of the skin and mucous membranes.
Allergic swelling may be accompanied by skin rash and itching. With allergies, histamine and serotonin are produced, which increase the permeability of the capillaries and lead to edema.
What if you have edemas?
When edema of any location and any origin is recommended immediately to see a doctor.
With cardiac, renal, venous and hepatic edema, an effective action will be the use of diuretics.
With allergic and inflammatory edema - taking antiallergic (antihistamine) drugs. With arthritis and arthrosis - the use of anti-inflammatory drugs.
Edema itself is not a disease, but only an effect, and you need to treat the underlying disease. A competent treatment can appoint only a doctor.
