Most of the signs of kidney diseases are unnoticed, ignored, or appear very late in the disease. Over 37 million American adults have kidney diseases, and most are not aware of it.
The surest way to know whether you have a kidney disease is to consult a doctor to get examined and tested. Some of the common signs that may indicate that you have a kidney disease are as follows:
- Feeling tired or lethargic: Kidney diseases may make you feel as if you lack energy. You may get tired easily and have difficulty concentrating. A severe decrease in kidney function can lead to a buildup of toxins and impurities in the blood. It also causes a reduction in red blood cells. This can cause people to feel tired and weak and can make it hard to concentrate.
- A change in urine frequency and quantity: Kidney diseases may be associated with an increase in urine frequency and amount. Some people may report decreased urine frequency or having scanty urine.
- Blood in urine: In certain cases, the urine may be “cola-colored” or “frank red.” This is because of damage to the filters in the kidneys.
- Frothy or foamy urine: A smelly urine that froths or foams may point to either an infection of the kidneys or filtering out of albumin in the urine. Albumin is a protein, and its presence in the urine points to kidney damage.
- Presence of puffy face and swollen ankles: The loss of proteins cause swelling over the ankles and feet, especially in the mornings. Sometimes, facial swelling (moon face) may also be seen. Swelling that occurs when asleep and goes away during the day must be investigated for kidney diseases.
- Having trouble sleeping: Kidneys are responsible for filtering out wastes from the body through urine. There is also restlessness of legs during sleep, which is believed to be due to an increased urea level in the blood. Kidney diseases are commonly associated with being overweight/obese and sleep apnea (snoring or having trouble breathing during sleep).
- Dry and itchy skin: Kidney diseases may cause a buildup of toxins such as urea and uric acid under the skin. This along with an imbalance of nutrients in the body cause skin problems.
- Loss of appetite: This is a nonspecific sign that may occur in many conditions including kidney diseases.
- Muscle cramps: Deficiencies and imbalance in essential nutrients such as calcium, vitamin D, and magnesium may cause muscle cramps in people with kidney diseases.
