3. Unusual swellings
The kidneys also regulate sodium levels and fluid elimination in the body. When they malfunction, 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 albumin levels in the blood. Similar swelling can also result from heart, liver, or venous disorders. If these symptoms persist, it is important to consult a healthcare professional for a thorough examination.
4. Shortness of breath
Although often associated with heart or lung disease, shortness of breath can also be caused by kidney disease. When kidneys malfunction, they fail to properly remove excess fluids and toxins, which can build up in the lungs, causing difficulty breathing. A reduced red blood cell count worsens this feeling of lack of oxygen.
In severe cases, a feeling of suffocation when lying down may occur, requiring urgent medical intervention.
5. Dry and itchy skin
The kidneys regulate not only blood purification but also mineral levels 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 become widespread, and the skin may take on a yellow or brownish tint.
Dermatologists sometimes discover underlying kidney problems in patients with persistent itching or rashes.
6. Bad breath and metallic taste
People with kidney disease may experience a metallic taste in their mouth, accompanied by unpleasant breath due to the buildup of toxins such as urea in the blood. This metallic taste, often associated with a loss of appetite, can also be accompanied by nausea and vomiting. It is advisable to consult a professional at this stage for a complete evaluation.
