Treating proteinuria or protein in the urine depends on the underlying issue, since proteinuria is not a remarkable disease, notes WebMD. Mild cases of proteinuria may need no treatment at all. However, if a serious ailment is the cause, such as kidney disease, medical care is necessary.
Treatment plans may include diet changes, medications and lifestyle adjustments, says the National Kidney Foundation. The kidneys filter and manage protein in the body. If protein is leaking into urine, the kidney filters may be damaged. Diabetes and high blood pressure are two common risk factors for proteinuria, reports WebMD. Additional causes are infections, toxins and immune system disorders.
