2. Swelling in the Feet or Ankles at Night
Mild swelling of the feet, ankles, or hands in the evening or after lying down may be a sign of kidney problems. Weak kidneys reduce the ability to excrete sodium and water, causing fluid retention in the body. According to a study in the American Journal of Kidney Diseases, peripheral edema is a common symptom in patients with chronic kidney disease.
3. Insomnia or Sleep Disturbances
Kidney damage can also have effects on sleep quality.
