Proteinuria refers to urinary protein excretion exceeding normal levels (typically greater than 150 mg/day in adults, or greater than 30 mg/mmol on urine albumin-to-creatinine ratio). Normally, the glomerular filtration barrier prevents large proteins from entering the filtrate. Damage to the glomerular basement membrane — from diabetic nephropathy, hypertensive nephropathy, IgA nephropathy, minimal change disease, focal segmental glomerulosclerosis, lupus nephritis, or pre-eclampsia — allows protein to leak into the urine.

What lifestyle changes can help with proteinuria?

Blood pressure control (target below 130/80 mmHg) significantly reduces glomerular damage and proteinuria progression. Glycaemic optimisation in diabetes is foundational. Low-sodium diet reduces hypertension and kidney pressure. Smoking cessation reduces CKD progression risk. Maintaining healthy body weight reduces the metabolic burden on the kidneys. Adequate hydration (without excess) supports kidney function.

What integrative approaches support proteinuria?

First-line investigation includes repeat urinalysis, urine albumin-to-creatinine ratio (ACR), eGFR, blood pressure measurement, and fasting glucose (to exclude diabetic nephropathy). ACE inhibitors or ARBs are the cornerstone of treatment for proteinuria in diabetic and hypertensive nephropathy — they reduce intraglomerular pressure and proteinuria independently of blood pressure effect. For immune-mediated causes: corticosteroids, immunosuppressives depending on biopsy findings. Tight glycaemic control reduces progression of diabetic nephropathy. SGLT-2 inhibitors (e.g., dapagliflozin) have added evidence for reducing proteinuria and CKD progression.

When should I seek professional support for proteinuria?

Seek urgent medical assessment for heavy proteinuria with oedema (possible nephrotic syndrome), proteinuria in pregnancy (possible pre-eclampsia), or rapidly declining kidney function. All persistent proteinuria requires nephrology or doctor-led assessment with systematic workup.

Quick answer

Proteinuria describes the presence of abnormal amounts of protein in the urine — a key indicator of kidney disease, glomerular damage, or systemic conditions affecting the kidneys. ICD-10: R80 (proteinuria); ICD-11: MF38. Requires medical investigation to determine cause and guide management.

Recognition

Do any of these feel familiar?

Proteinuria produces no direct symptoms when mild. Significant proteinuria may cause frothy or foamy urine. Associated oedema (swelling of legs and around eyes) occurs in nephrotic syndrome.
