In general, kidney atrophy measuring 3 cm is considered severe.

As an important organ in the human body, the kidney performs multiple functions, including urine formation, removal of metabolic waste, and maintaining internal environmental stability. Causes of kidney atrophy are varied, including chronic glomerulonephritis, hypertensive kidney disease, and diabetic nephropathy. When kidney size decreases by 3 cm, it usually indicates that normal kidney function has been significantly affected.

Kidney atrophy may lead to impaired excretion of metabolic waste from the body, thereby triggering a series of health problems. As the condition progresses, patients may experience symptoms such as fatigue, hematuria, and nausea, and may even develop serious complications such as chronic renal failure or uremia. Therefore, kidney atrophy measuring 3 cm is considered a serious condition.

During treatment, patients should maintain healthy lifestyle habits, such as regular sleep patterns and dietary adjustments, which can aid in recovery. Regular monitoring of kidney function changes and timely adjustment of treatment plans can help delay the deterioration of kidney function and improve quality of life.
