6. Poor Concentration and Dizziness
As your kidneys become overwhelmed with toxins, they begin to fail, which can lead to inefficient oxygen flow to the rest of your body, including your brain.
This leads to such things as poor memory, concentration, and dizziness, and even light-headedness— brain fog.
7. Pain in Your Lower Back
Lower back pain is often associated with kidney damage, failure or infections since these organs sit in your lower back area. This pain can be a result of kidney stones or even a urinary tract infection.
You may also experience pain in your legs or sides.
In healthy people, your kidneys produce a hormone known as EPO (erythropoietin), which essentially increases the number of red blood cells in your blood. These red blood cells carry valuable oxygen to every part of your body.
A general lack of oxygen, not surprisingly, can lead to fatigue, including your muscles and every other working part of your body.
Chronic fatigue may also be a symptom of anemia, so it is imperative you speak with your health professional if you have long-term, unexplainable exhaustion.
