Different underlying conditions can cause proteinuria. The treatment of proteinuria focuses on controlling the underlying condition causing proteinuria and minimizing its progression. Therefore, treatment for each condition is likely to be different. For example, someone with diabetes should carefully monitor and control their blood sugar levels to help to preserve kidney function. Someone with high blood pressure (hypertension) will need to control blood pressure to prevent progressive kidney damage. Preeclampsia-related proteinuria during pregnancy will be carefully monitored and usually resolves once the baby is born. Sometimes medications, such as blood pressure medication, will be prescribed depending on the severity of the preeclampsia.
People with persistent proteinuria and especially those with reduced kidney function may receive recommended dietary changes from their healthcare provider, such as minimizing intake of protein or cholesterol-rich food products. No treatment may be necessary for mild or transient proteinuria.
