5 silent signs of kidney disease: Most people don't realize it
Kidney failure causes toxins to build up in the blood and affects energy levels. It can also cause anemia when the kidneys do not produce enough erythropoietin (a hormone responsible for stimulating red blood cell formation). This causes chronic fatigue, lack of concentration, and shortness of breath during mild activity. Many patients dismiss this as normal fatigue or aging, and diagnosis is delayed.
CHANGE IN URINATION HABITS
Changes in urine frequency, color, or appearance are often the first signs of kidney problems but are rarely considered serious. Nocturia, or frequent nighttime urination, foamy or frothy urine (indicating protein loss), hematuria, or blood in the urine, or very dark urine are signs of possible kidney damage. Ignoring these changes, even if they seem minor, can allow the disease to develop insidiously.
If the kidneys are unable to remove excess sodium and fluid from the body, swelling (edema) occurs, which is easily visible, especially in the legs and around the eyes. Patients often attribute the swelling to standing for long periods of time or poor nutrition, but it may be evidence of kidney failure. It is important to detect and test as soon as possible.
One of the lesser-known symptoms of kidney failure is persistent itching (pruritus). This is caused by imbalances of waste products and minerals such as calcium and phosphorus in the blood. Dry, scaly skin and persistent itching, especially without a dermatological cause, should be evaluated with a kidney exam.
ANOREXIA
As kidney function deteriorates, the body accumulates uremic toxins, producing gastrointestinal symptoms such as metallic taste in the mouth, bad breath (uremic fetor), nausea, or loss of appetite. These symptoms are often misinterpreted as digestive problems, leading to misdiagnosis or delay in treatment.
If you or someone you know is experiencing any of these symptoms, especially if you have risk factors such as diabetes, high blood pressure, a family history of kidney disease, or long-term painkiller use, see a healthcare professional immediately. Early diagnosis can be made with kidney function tests (routine blood tests such as creatinine, eGFR, and a urine test to measure albumin), which can help prevent serious complications and improve quality of life.
The key to maintaining kidney health is awareness and taking quick action. Don’t ignore the subtle signals your body is giving you; remember, your kidneys may be silently whispering for help.
