Fatigue, insomnia, itchy skin, swollen feet, bad breath or abnormalities in urine… can be signs of impaired kidney function.
Kidney disease in the early stages rarely shows signs, but when it enters the advanced stage, the symptoms on the body gradually become obvious. With a basal metabolic test (BMP), your doctor will detect abnormalities in your kidneys that are related to creatinine or urea levels in your blood. In addition, some of the following signs may warn of kidney disease:
The kidneys filter waste from the blood and pass it out of the body through the urine. When the kidneys are not working properly, it can lead to a build-up of toxins, which in turn causes fatigue, feeling drained of energy, weak or difficult to concentrate. Fatigue is also a manifestation of the kidneys not secreting hormones that stimulate the production of red blood cells, making the blood unable to supply enough oxygen to the muscles and brain.
Poor sleep, insomnia
Many studies show a link between sleep apnea and chronic kidney disease (CKD). CKD causes kidney damage that increases the risk of accumulation of toxic substances. High levels of toxins make it harder for people to fall asleep. Besides, CKD can be the cause of sleep apnea due to narrowing of the throat, accumulation of toxins, etc.
Toxins are not eliminated by the kidneys, but accumulate in the blood, leading to itching or rashes all over the body. Damage from the kidneys causes the body to not be able to balance minerals and nutrients, causing the skin to dry out and cause itching.
Swollen face and feet
Swelling can also be a sign of a buildup of sodium, a fluid in the body. swelling may appear in the hands, feet, ankles, or face. Protein leaks out of the urine due to poorly functioning kidneys can also cause puffiness around the eyes.
Cramps in the legs and other organs can be a sign of impaired kidney function. It is caused by an imbalance in the levels of sodium, calcium, potassium, or other electrolytes that disrupt the functioning of muscles and nerves.
Shortness of breath
With kidney disease, the body doesn’t produce enough of a hormone called erythropoietin. This hormone has a role in prompting the body to make red blood cells. When erythropoietin is low, the body is at risk of becoming anemic and feeling short of breath. Another cause is the accumulation of fluid that will make it difficult for the person to breathe.
Toxins that are not eliminated from the body can affect the brain. Anemia also causes the brain to be deprived of oxygen, making the patient feel dizzy, difficult to concentrate and memory impaired. This is called brain fog.
A buildup of toxic substances can cause a condition called uremia. This is what causes bad breath. In addition, toxins in the blood can change the taste of food and make it difficult to eat.
Changes in urine
Foamy urine can be a warning sign of kidney problems. In addition, people with kidney disease may also experience brown or very light urine. Impaired kidney function can also cause blood to leak into the bladder, leading to blood in the urine.
