When should proteinuria be treated? – VnExpress

Low proteinuria may not require treatment, but only need to be periodically examined, on the contrary, if the proteinuria is not controlled, it will lead to kidney failure.

The kidneys filter and remove toxins from the body through urine; protein reabsorption into the blood. When the kidneys are not working properly, protein will constantly leak into the urine and become abnormally high, causing proteinuria (proteinuria). A person may experience proteinuria if the amount of protein in the urine is higher than 150mg/day.

BS.CKII Nguyen Huu Nhat, Department of Artificial Kidney – Center for Urology Nephrology, Tam Anh General Hospital in Ho Chi Minh City, said that if the amount of protein in the urine is low, the patient may not need to be treated but just monitored. regular and regular check-ups. However, long-term elevated proteinuria can be caused by underlying medical conditions that need to be treated early. Diseases that can increase proteinuria include hypertension and diabetes (the two most common causes), diseases related to the urinary system such as nephrotic syndrome, glomerulonephritis, kidney cancer.. .; rheumatoid arthritis, lupus, multiple myeloma, preeclampsia…

At this time, the treatment regimen will depend on the cause of the disease and combine with adjustments in daily living habits. Active treatment of the underlying cause will help control proteinuria well, thereby prolonging the duration of medical treatment, slowing down the rate of development of end-stage renal disease, reducing the risk of dialysis and reducing the risk of kidney disease. dead.

For example, if the cause of the disease is diabetes, the patient needs to follow the doctor’s instructions in taking medication and follow a reasonable diet to help control blood sugar, exercise regularly, GFR blood test periodically measures glomerular filtration rate… While in people with high blood pressure, the doctor may prescribe certain medications to help lower blood pressure and slow kidney damage, such as enzyme inhibitors. It helps to widen blood vessels, helps the kidneys to dehydrate, and reduces hormones that increase blood pressure; or angiotensin receptor blockers dilate blood vessels, lowering blood pressure.

In some cases, proteinuria can be increased for a short time in people who do heavy work, play sports too hard, are dehydrated, people with fever or people who are being treated for other diseases. Proteinuria will return to normal when the above health problems are overcome.

In the early stages, proteinuria often has no obvious symptoms but develops silently. This condition may only be discovered when a person happens to have a urine test to diagnose another condition. When the patient notices symptoms such as frequent urination at night, urine that is dark yellow and foamy, even greasy, loss of appetite, nausea, trouble sleeping, swelling of the face, swelling of the hands or feet, nocturnal cramps…meaning that the disease is advanced, the kidneys may have been damaged. Patients face the risk of chronic kidney failure, increased risk of cardiovascular disease and death.

Dr. Huu Nhat said kidney damage is irreversible, and treatments are only intended to slow down the disease’s progression and prevent complications. Therefore, patients need to be aware that prevention is better than cure. Specifically, the patient should follow a scientific lifestyle such as limiting alcohol, stopping smoking; regular exercise, at least 30 minutes a day; increase fiber, limit foods rich in fat and salt; take medicine as prescribed by the doctor and well control the underlying diseases; urine protein test at least once a year… At the same time, it is necessary to go to the hospital for medical examination as soon as abnormality is noticed in the urine.
