Treatment for protein leaking from the kidneys into urine, a condition called proteinuria, includes taking drugs such as angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, states WebMD. Patients with temporary or mild proteinuria may not need treatment. As proteinuria is not a disease, its underlying cause determines its treatment.
Diabetes and hypertension commonly cause kidney damage that can lead to excessive protein in the urine, but other causes include immune system disorders, injuries, medications, infections and toxins, notes WebMD. Multiple myeloma and amyloidosis can stimulate protein production in the body, resulting in proteinuria. People at risk of developing the disorder include those over age 65, obese individuals, those who have a family history of kidney disease and pregnant women who develop preeclampsia.
