2. Persistent Fatigue and Weakness
Feeling constantly tired or weak, even after resting, may indicate kidney disease.
Why It Happens
- Kidney dysfunction leads to a buildup of toxins in the blood, making you feel exhausted.
- Low red blood cell levels (anemia) occur when the kidneys fail to produce erythropoietin (EPO), a hormone that stimulates red blood cell production.
When to See a Doctor
- If fatigue lasts for weeks without an obvious cause.
- If you experience dizziness, trouble concentrating, or shortness of breath.
3. Swelling in the Feet, Ankles, or Hands
Unexplained swelling (edema) in the lower body is a common silent sign of kidney disease.
Why It Happens
- Damaged kidneys can’t remove excess sodium and fluids, leading to fluid buildup.
- Swelling may also indicate protein loss, which disrupts fluid balance in the body.
When to See a Doctor
- If swelling persists despite reducing salt intake.
- If swelling spreads to the face or around the eyes.
4. Dry and Itchy Skin
Persistent dryness, itching, or rashes can signal kidney disease.
Why It Happens
- The kidneys help balance minerals like calcium and phosphorus.
- When they fail, toxin buildup and mineral imbalances cause dry, itchy skin.
When to See a Doctor
- If moisturizers and skincare treatments don’t relieve the itching.
- If itching is worse at night or affects large areas of the body.
