The kidneys are one of the most important organs in the body. They filter 120-150 quarts of blood every day and allow everything to function properly. They keep the blood stable, prevent extra fluid buildup and keep the waste out of the body, and by keeping your electrolyte levels stable they improve the strength of your bones and regulate your blood pressure.

When the kidneys are damaged, your overall health is in danger. This is why you need to recognize the early signs of kidney damage and prevent it on time.

Here are the most common symptoms of kidney damage:

1. Swelling
When damaged, the kidneys can’t remove excess fluids from the body, which results in swelling in the limbs and face. Sudden swelling of your body parts can also be caused by kidney failure.

2. Changes in urination
If you feel changes in the frequency and color of your urine, it may be a sign of kidney damage.

3. Skin rashes
Kidney failure causes skin rashes and itching as the organs aren’t able to remove toxic waste from the blood. Ointments and creams can treat the skin, but they won’t treat the underlying problem.

4. Fatigue
When the kidneys are healthy, they produce a hormone called EPO which is responsible for the creation of new red blood cells which carry oxygen to the tissues. If there’s a lower amount of red blood cells in your body, the kidneys won’t get enough oxygen and will suffer as a result.

5. Shortness of breath
Low amount of red blood cells caused by kidney damage will leave the body without oxygen and result in shortness of breath.

6. Metallic taste in the mouth
When waste material accumulates in your blood it may cause metallic taste in your mouth, as well as a change in your appetite.

7. Pain
Pain in the upper back can be a sign of kidney damage, as well as a symptom of kidney stones.

8. Trouble focusing and dizziness
When the brain isn’t getting enough oxygen as a result of kidney damage, it leads to anemia, a condition that’s known to cause loss of focus, dizziness and memory loss.
