Kidney - a pair body which is located at the back of the abdominal cavity, on each side of the spine.
Their proper functioning plays a very important role in human health as well as the kidneys are responsible for maintaining the level of electrolytes, blood pressure and fluid balance in the body.
As is the case with other systems of the body, they are susceptible to infection and disease.
Although these diseases are not so common, is the problem that they are virtually no symptoms at early stages and are often very difficult to diagnose them in time.
The only way to accurately determine the presence of a problem - it is to undergo a medical examination and a blood test and urine.
However, there are some symptoms that will also help in time to "sound the alarm" at the slightest deviation from the norm.
Below, we describe in detail about the 7 most common symptoms, speaking about the problems with the kidneys. Be sure to contact your doctor if any of these you will find familiar.
1. Excessive fatigue
Chronic fatigue is a result of the fact that the blood carries less oxygen to the body's cells. The reason for this may also be a problem with the kidneys.

Due to the failure of the kidneys waste accumulate in the tissues, and you start to feel itching or tingling under the skin.
Fluid retention, or edema is one of the main symptoms of kidney disease.
Although the appearance of swelling depends on many factors, renal insufficiency is the main reason.
These agencies monitor the water level, and sodium in the body, so that any "failure" does not allow them to appropriately balance these indicators.
This symptom can also occur when the body is a large protein loss through the urine, a condition called nephrotic syndrome.
Inflammation and swelling are often concentrated in the legs and ankles, but can sometimes appear on the hands, face and other parts of the body.
4. Kidney and anemia
The presence of anemia in patients with a sign that kidney disease is already quite serious.
Because the kidneys are responsible for the production of a hormone called erythropoietin, which stimulates the bone marrow, causing it to produce red blood cells.
If this function is impaired due to the severe stage of renal failure, the level of blood cells is greatly reduced, and patients develop chronic anemia.
5. Pain in the back
Pain in the lower back or side may be a signal, speaking of a possible kidney disease, particularly in elderly patients.
Although this is not a very common symptom, it can take place in the presence of kidney stones or urinary tract.
In these cases, the pain is usually very intense and is usually accompanied by other symptoms, such as difficulty urinating, or burning.
It is important to distinguish this condition from pain in the muscles, because it may be the key to early detection of serious diseases.
