What are examples of kidney disease symptom?

Kidney disease, also known as renal disease, often does not cause signs and symptoms in its early stages. As kidney damage worsens, signs and symptoms may include:

* High blood pressure (hypertension). The kidneys help regulate blood pressure. When they're damaged, they may not be able to control blood pressure as well.

* Swelling (edema) in your hands, feet, ankles, and around your eyes. This happens because the kidneys aren't able to remove excess fluid from your body.

* Foamy or bubbly urine. This can be a sign of protein in the urine, which is a marker of kidney damage.

* Frequent urination, especially at night. This happens because the kidneys aren't able to properly concentrate urine.

* Loss of appetite. When the kidneys are damaged, they can't produce a hormone that helps control appetite.

* Nausea and vomiting. These symptoms can occur when the kidneys aren't able to remove toxins from the blood.

* Muscle cramps. This happens because the kidneys aren't able to balance electrolytes, such as calcium, sodium, and potassium, in your body.

* Fatigue. This can be a sign of anemia, which is common in people with kidney disease.

* Itchy skin. This happens because the kidneys aren't able to remove waste products from the blood.

* Back pain. This can be a sign of kidney stones or a kidney infection.

When to see a doctor

If you have any of these signs or symptoms, it's important to see your doctor for evaluation. Early diagnosis and treatment of kidney disease can help to slow or stop the progression of the disease and improve your quality of life.
