1. Foamy Urine
Occasional bubbles in urine are usually harmless and not a cause for concern. However, urine that consistently appears unusually foamy may signal the presence of protein in the urine, a condition known as proteinuria.
Normally, healthy kidneys prevent important proteins such as albumin from leaking into the urine. When the kidney’s filtering units are damaged, albumin and other proteins can pass through into the urine, causing it to look foamy.
To confirm proteinuria, a urine test is necessary. If protein is detected, it may indicate kidney damage and warrants further evaluation by a healthcare professional.
2. Swelling in Feet and Ankles
Your kidneys play a crucial role in removing excess sodium and fluid from your body. When kidney function declines, fluid can build up in the tissues, leading to swelling, known as edema.
This swelling is often noticeable around the feet, ankles, and legs. However, it is important to remember that swollen legs can also result from other causes such as heart disease, liver problems, vein conditions, certain medications, or prolonged periods of sitting or standing.
3. Persistent Fatigue
Feeling unusually tired or weak can be a symptom of advancing kidney disease. When kidney function is reduced, waste products accumulate in the bloodstream, which can contribute to fatigue.
Kidney disease can also cause anemia, a condition characterized by a shortage of red blood cells, which further exacerbates feelings of weakness and difficulty concentrating.
Since fatigue is common and can arise from many different conditions, it is not a definitive sign of kidney disease on its own but should be considered alongside other symptoms and risk factors.
