5 serious signs warning of kidney damage

Besides filtering waste from the blood, regulating blood pressure, and balancing electrolytes, the kidneys also secrete hormones and perform many other functions. Therefore, whenever the kidneys are weakened, the body will experience a series of problems.

Many people only discover they have kidney disease when their kidney function has severely deteriorated and caused numerous adverse symptoms. Experts recommend that people with high blood pressure, diabetes, those over 60 years old, and those with a family history of kidney disease should have regular kidney health checkups, according to the health website Verywell Health (USA).

Electrolyte imbalances caused by impaired kidney function will frequently lead to muscle cramps.

Serious warning signs of kidney damage include:

Frequent urination

One common symptom warning of kidney problems is frequent urination. Frequent nighttime urination can disrupt sleep and lead to exhaustion. Frequent urination can also be a warning sign of conditions such as interstitial nephritis or kidney damage due to sickle cell anemia.

Dry and itchy skin

Healthy kidneys effectively remove waste and excess fluids from the body while maintaining healthy mineral levels in the blood. When kidney function declines, the balance of waste and minerals in the blood becomes disrupted. This can result in dry and itchy skin.

Foamy and foul-smelling urine

Foamy urine with a foul odor is a sign that the protein content in the urine is abnormally high. This is especially true when you have to flush multiple times to get rid of the foam. This foam looks similar to the foam that appears when whisking eggs. This is because the protein in urine is albumin, a protein also found in abundance in eggs.

Swollen ankle

Impaired kidney function affects the body's ability to eliminate fluids. This can lead to fluid buildup and swelling in the legs, especially the ankles. Besides kidney problems, foot swelling can also be a sign of heart, liver, or venous disease.

Muscle cramps

People with advanced kidney disease often experience muscle cramps. These cramps are painful and can be prolonged. This is because weakened kidneys cause an electrolyte imbalance in the blood, according to Verywell Health .
