5 Signs That Your Kidneys May Be Sick

With little or no symptoms visible, kidney disease is often diagnosed at late stages. From a simple fatigue, urinary problems through frequent itching, these signs may announce kidney failure, severe chronic disease that affects nearly 20 million Americans. So recognizing the symptoms of this disease is important to detect it in time and limit the damage. These are signs you should not ignore!

Kidneys are vital organs that provide major functions:

– Filter the blood
– Remove toxins and waste from the body
– Produce hormones that play an important role in the regulation of other body functions (blood pressure …)
– Regulate the concentration of the minerals and the liquid levels in the body

Kidney failure, what is it?

Kidney failure means the gradual decline of renal function caused by the destruction of nephrons constituting the kidneys. These tissues can no longer filter blood or secrete some hormones, leading to serious imbalances in the body.

This disease develops gradually and slowly, and is often devoid of signs, which makes it very difficult for early diagnosis. Indeed, most cases of renal insufficiency are only detected at advanced stages.

We distinguish chronic renal failure and acute renal failure. It occurs suddenly and is usually caused by dehydration or serious infections.

Chronic renal failure is itself the consequence of other diseases such as diabetes and high blood pressure, which cause damage to blood vessels throughout the body, even those of the kidneys.

However, other risk factors can also promote the onset of chronic kidney disease, namely:

– Polycystic kidney disease
– Abnormalities of the urinary tract
– Pyelonephritis
–  Autoimmune diseases such as lupus

Symptoms of kidney failure

Kidney failure is a disease that develops slowly, therefore the symptoms can be easily overlooked. These occur gradually and may be associated with various other pathologies, without suspecting kidney failure.

However, some signs can be alarming and require special medical attention:


Persistent fatigue is one of the main symptoms of kidney failure. Indeed, the kidneys are the main source of erythropoietin, a hormone involved in the production of red blood cells by the bone marrow. Their dysfunction leads to lower secretion of this hormone, which will cause a decrease in red blood cell levels in the blood. Result: anemia sets in and is accompanied by fatigue.

This sign is actually the result of a domino effect caused by a malfunction of the kidneys.
In addition, fatigue in patients with renal failure may also be caused by the accumulation of waste in the blood.

Urinary problems

Urinary problems may announce several diseases, including kidney failure. The person may experience frequent urination, especially at night, and may also notice color changes in the urine, which can be lighter or darker. In some cases, there is blood in the urine.
A decline in the volume of urine and pain during urination are also signs to be reckoned with!

Pain in the lower back

The pain in the lower back or on one side should set off the alarm. The pain may appear on one side and may extend towards the other. It is embarrassing and uncomfortable in everyday life.


Swelling of the feet, ankles or face are signs not to be taken lightly as they may reveal kidney failure. Indeed, when the kidneys don’t function well, they fail to properly filter the blood. Toxins tend to accumulate in the body and cause swelling in various body parts.

Dry, itchy skin

Kidney failure can cause itching. This phenomenon is mainly caused by a high level of phosphorus in the blood. It binds calcium and both form crystals which cause itching.

Other warning signs of kidney failure that are not to be overlooked:

– Loss of appetite
– Nausea and vomiting
– Metallic taste in mouth
– Shortness of breath
– Cramps
– Excessive thirst
