Swelling in the morning of the upper and lower eyelids especially on the face, in the evening, it is difficult to fasten the boots and shoes, perfectly dressed in the morning, begin to bear squeeze feet, appear on the skin deep imprints on the gum socks….
How often do we have to deal with such phenomena! But these symptoms are not always safe because it is the first signs of the edematous syndrome. The causes of edema, especially explicit, are always a manifestation of diseases of any internal organs or blood vessels. They themselves do not pass, and if you do not pay attention to them, you can later cause serious health problems.
So, where do you start? First, you must find out the reason why the leg began to swell and / or face. There are many diseases and conditions that are accompanied by the causes of edema, so the differential diagnosis should hold a specialist — a doctor.
Varicose veins of the lower limbs — one of the main reasons why swollen legs. The most common is in women. In normal veins involved in the circulation, their walls have a certain «power» — tone, through which blood returns back to the heart against the hydrostatic pressure at the height of human growth. Valves inside the veins are not bled down. When varicose vein disease is somewhat weaker walls, and under certain conditions (for example, long-term work on their feet, pregnancy, etc.) Cannot withstand the pressure and expand, take the form of «bags» nodes, bundles. Return the blood decreases, it stagnates in the veins, and its liquid part goes into the fabric — there is swelling. The more time a person spends on his feet — the more swelling. They occur mainly on the legs and are accompanied by weight, pain in the legs (or one foot). The causes of edema are increasing in the evening, leave or reduced per night. If varicose veins have been around for a while, then changes color and moisture of the skin, may stain, hair fall out. Not always veins show through the skin. Sometimes defeat the deep veins that are not visible.
Dangerous varicose accession thrombophlebitis is inflammation of a vein with clot formation within it — a blood clot. Blood clots can break away from the vein wall and enter the bloodstream to the lungs — where they clog the vessel turns pulmonary infarction. It is best to avoid this time and to be treated (or operated) in the vascular surgeon.
Swelling with kidney disease causes of edema
Of all kidney disease is more common pyelonephritis and glomerulonephritis.
Pyelonephritis — an inflammation of the kidney caused by pathogenic bacteria or fungi. It usually manifests fever, low back pain, and sharp pains during urination (dysuria).
Glomerulonephritis — a more serious disease that causes kidney failure. If there are also back pain, malaise, weakness. Dysuria missing, but in the urine detected a lot of protein, red blood cells (red urine), increased blood pressure.
The causes of edema in renal disease may first appear on the face, especially the eyelids, and then at the ankles, legs, and even higher: arms, abdomen. And there in the morning, by the end of the day on his feet amplified. The skin is not changed, warm, maybe a little pally. Their origin is connected with the difficulty of isolation diseased kidneys salts and water (excess water remains in the body) and loss of protein through the kidney (normal protein retains water in the bloodstream, it does not seep through the vascular wall into the tissue). Often swelling — the first symptom of kidney disease, as well as pyelonephritis and glomerulonephritis, can flow hidden (latent) for several years.
Swelling at heart disease causes of edema
Arterial hypertension and coronary heart disease (angina pectoris) are the scourge of our time. Their prevalence — is enormous. And then there are heart disease, cardiomyopathy … Any disease affecting the heart muscle (myocardium) causes a decrease in the contractile ability of the heart, weakens it, and after sometimes contributes to the emergence of heart failure. That a situation arises in which the heart becomes hard to pump the entire volume of blood and part of it remains, so to speak, on the periphery (usually in the lower limbs). The liquid part of it seeps into the fabric — there is swelling. Typically, heart failure and impaired renal function (reversible), they do not take the extra fluid and salt, which increases swelling.
Swelling in heart failure are growing for a few days or weeks, the skin is usually pale, cool, sometimes with bluish molasses. Accompanying symptoms such as weakness, palpitations under load, shortness of breath, change in pressure, can be a pain and disruption of the heart (irregular heartbeat).
Swelling of liver diseases
By themselves, liver disease (hepatitis) does not give rise to swelling. Swelling in step complications appear when the disease becomes cirrhosis. In cirrhosis is also delayed in the water body, besides suffering from liver produces enough protein falls so-called oncotic pressure of the blood, the liquid is not retained in the bloodstream.
May swell foot, shin, thigh, stomach (especially true!). They are accompanied by yellow skin and eyes, bruises on the skin, weakness, heaviness in his right side, weight loss, sometimes significant increase in the liver.
Allergic causes of edema
They have quite a characteristic pattern and is usually accompanied by redness, itching and rash often. This swells the skin on the face, neck, in severe cases, swelling of the skin covers the entire body. It also may be hoarseness, nasal congestion, watery eyes. These symptoms occur after exposure to the allergen: certain foodstuffs (citrus fruits, fish, etc.)., A drug, aerosols and other.
First of all — it is the pathology of thyroid deficiency of its function — hypothyroidism. It can be of different origin: autoimmune, post-operative, as a result of iodine deficiency in the diet, and so on, but regardless of the cause of the thyroid gland produces little hormones. One of the signs of hypothyroidism is a dense swelling — myxedema. Myxedema is most noticeable on the face, but it extends to the whole body. In addition, to swelling and other symptoms are present: sluggishness, sleepiness, loss of memory, chilliness, slowing heart rate, menstrual irregularities, decreased body temperature, etc. The thyroid gland may be at increased or decreased.
Lymphostasis causes of edema
It is also the cause of edema. Can occur in principle on any part of the body (face, breast, arm), but mostly still in the lower extremities (or on one leg). In addition, to the veins and arteries in the human body has lymphatics they particularly exchanged and outflow of fluid from the fabrics. In the case of violation of the outflow of lymph stagnates gradually more and more, the affected part of the body is significantly increased in volume, the contours of her deformed, impeded mobility. Swelling of proof, after the rest will not. Early lymphocytosis characteristic symptom — the inability to collect in the folded skin over the affected area when the swelling is still small.
Summarize causes of edema
These are state — not a complete list of the diseases that can cause edema. It is important to remember that the swelling is just a symptom of an illness of an organ, and no single recipe cures them — do not exist. Diseases of the kidney, liver, heart, thyroid gland, blood vessels — are treated differently, and even the treatment of the same disease in two different people may differ.
Therefore, if you suddenly appeared causes of edema — do not rely on the advice of «experienced» people — go to a clinic, lab and turn a simple set of analyzes:
- general blood analysis,
- general urine analysis,
- biochemistry: total protein, urea, creatinine, ALT, AST, bilirubin, blood sugar, cholesterol;
- Ultrasound of internal organs.
Refer to a specialist, he will understand and prescribe appropriate treatment. And remember: the self-administration of drugs can be dangerous. For example, an incorrect reception for a long time diuretics (incorrect dosage intervals between doses, the duration of the course) often leads to irreversible loss of renal function.
