Urologists note that fatigue caused by kidney problems can make even the simplest tasks, such as walking or taking a shower, difficult. To eliminate any doubt, a blood test is recommended to detect possible anemia associated with kidney problems.

3. Unusual swellings
The kidneys also regulate sodium levels and fluid removal in the body. When they are not functioning properly, excess fluid can accumulate as swelling in the ankles, feet, hands, or under the eyes, especially noticeable in the morning.

Edema : This buildup of fluid, called edema, is caused by low levels of albumin in the blood. Similar swelling can also result from heart, liver, or vein problems. If these symptoms persist, it is important to see a healthcare professional for a thorough evaluation.
4. Shortness of breath
Although often associated with heart or lung disease, shortness of breath can also be caused by kidney disease. When kidneys are malfunctioning, they are unable to properly remove excess fluids and toxins, which can build up in the lungs, causing difficulty breathing. A reduced number of red blood cells makes this feeling of lack of oxygen worse.

In severe cases, a feeling of suffocation when lying down may occur, requiring urgent medical intervention.

5. Dry and itchy skin
The kidneys not only regulate blood purification, but also the levels of minerals in the body, which are essential for healthy bones and skin. Dry skin and intense itching can indicate a buildup of toxins in the blood due to kidney dysfunction. Sometimes the itching affects a specific area, but it can also be generalized, and the skin may take on a yellow or brownish tint.
