8 Symptoms That Indicate Your Kidneys Are Not Working Well

The kidneys are the main filtration organ responsible for cleaning waste from the body. They filter about 190 l. of blood per day and remove up to 2 liters of water. By doing this, kidneys regulate our blood pressure and are able to produce the hormones our body requires. If their function is somehow impaired, the body will suffer from toxic overload and a host of diseases and conditions. This is why it’s important to recognize the signs of reduced kidney function and react on time.

Here are the 8 main symptoms that indicate your kidneys are not working well:

Changes in urination

If you’re feeling the urge to urinate frequently or your urine has changed its color and smell, it might be a sign of impaired kidney function. Check your urine – if it’s foamy or bubbly, it may be a sign of kidney problems. Noticing any kind of change in your urination is also a sign that you should visit a doctor.


Water retention is caused by reduced kidney function and may result in swelling in the face, feet and ankles.


The kidneys produce a hormone known as Erythropoietin which is involved in the creation of red blood cells and responsible for the transport of oxygen to the body cells. If the kidneys are somehow impaired, the production of the hormone will be reduced, resulting in anemia, tiredness, dizziness and difficulty focusing.

Pain in the lower back

Although it could be simply a pulled muscle, back pain can be related to kidney disease. Back and lumbar pain is sometimes caused by urinary tract infections.

A metallic taste in the mouth

The accumulation of toxins in the kidney may cause a metallic taste in the mouth, losing the taste of meat and may also cause bad breath.

Skin problems

If there isn’t proper oxygenation and blood filtering, toxins will accumulate in your blood and cause rashes, acne, allergies and itching.

Feeling cold

If you’re feeling cold all the time regardless of the season, it may be a sign of kidney disease.

Hypertension (high blood pressure)

Kidney problems may cause numerous issues in the cardiovascular system. The retention of water and sodium in the body can increase your blood pressure and, if left untreated, may result in chronic renal diseases.

If you notice any of these symptoms, visit a doctor immediately as kidney disease is a serious problem which can do a lot of damage.
