The kidney is one of the body's vital organs which has many functions essential for good health, such as the removal of toxins, blood filtration, hormonal functions, regulation of blood pressure, and more. The kidneys maintain fluid and electrolyte balance in the blood and throughout the body, through excretion of urine and filtration of the blood.
The kidneys are responsible for filtering waste through the blood using tiny filters, called nephrons, and flushing them out of the body via the urine. However, when nephrons get damaged, or worse, a kidney fails completely, waste builds up in the blood and can’t be eliminated from the body, which will result in health concerns.
Here are 4 symptoms of kidney disease that you shouldn't ignore:
1. Low back pain
If you have lower back pain, especially on the side you sleep on, it may be a sign that the kidney on that side is damaged. This pain is also accompanied by painful urination.
2. Skin problems
Some symptoms of kidney failure, one of the most common kidney diseases, are itchy and dry skin.
The kidneys, like the liver, are responsible for removing toxins from your body. Therefore, any kidney dysfunction can easily lead to skin related issues, such as rashes.
3. Swelling of different parts of the body
One of the worrying symptoms of kidney disease is swelling in different parts of the body. Remember that the kidneys purify the whole body by flushing out wastes, so failure to function can easily lead to the buildup of wastes, causing swelling.
4. A change in the color of the urine
With kidney failure, the color of your urine will change, it will become darker. The texture can also change, becoming more foamy and more concentrated. This symptom of kidney disease requires immediate medical attention.
Kidney failure can cause anemia
In addition to being responsible for your body's detoxification process, your kidneys are also responsible for carrying oxygen to red blood cells through the naturally occurring hormone erythropoietin. When the kidneys are damaged, they cannot properly secrete this hormone, which leads to anemia.
