Nephrotic syndrome generally does not cause itchy skin in patients. In patients with nephrotic syndrome, the glomerular filtration barrier is severely damaged, leading to a significant presence of urinary protein and edema, but itchy skin is a rare clinical symptom. If a patient experiences itchy skin, it is recommended to visit the dermatology department of a standard hospital. As such patients may have a disordered immune system, they are prone to various skin issues, such as allergic dermatitis and eczema, which might cause symptoms of itchy skin. However, these are not directly related to nephrotic syndrome.
