Symptom 9: Kidney Problems
Unlike some other symptoms, kidney issues might not present overtly. It’s a slow and silent progression. Early signs could be as subtle as a change in the frequency of urination or the appearance of the urine itself, becoming foamy or bloody.
The kidneys, essential for filtering out waste from the blood, can be affected by the presence of cryoglobulins. These protein clumps can clog the small blood vessels in the kidneys, impeding their filtering function. Over time, this can lead to conditions like glomerulonephritis, where the kidney’s tiny filters become inflamed and less efficient.
As kidney function diminishes, various signs might emerge. Swelling in the ankles, feet, or hands can become pronounced. Blood pressure might spike due to the kidney’s reduced ability to balance fluids. Fatigue, itchy skin, or even nausea can become frequent companions, hinting at the impaired kidney function. (9)
