Kidney Disease Warning Signs You Shouldn’t Ignore, Doctors Explain

The kidneys act as natural filters in the body, helping remove waste and excess fluid from the blood through urine. Chronic kidney disease (CKD) can develop gradually and may not cause obvious symptoms in its early stages. As the condition progresses, changes such as frequent urination at night, foamy or unusually colored urine, fatigue, reduced appetite and swelling may become noticeable. Severe kidney dysfunction can lead to significantly reduced urine output, persistent nausea or vomiting and other serious complications.

Doctors generally assess kidney health using tests such as serum creatinine and estimated glomerular filtration rate (eGFR), along with urine albumin-to-creatinine ratio (UACR). Ultrasound may also be recommended to evaluate kidney size, structure or possible blockages. Diabetes and high blood pressure are important risk factors for kidney damage, so keeping both under control is essential. Dietary restrictions, including salt and certain nutrients, should be individualized according to kidney function and medical advice. Dialysis is considered in advanced kidney failure, but the decision is not based on eGFR alone. Severe fluid overload, dangerously high potassium levels, breathing difficulty due to fluid in the lungs and other complications can require urgent treatment. Kidney transplantation may be considered for suitable patients with kidney failure.
