Proteinuria includes physiological proteinuria and pathological proteinuria. Physiological proteinuria refers to proteinuria in urine due to some transient factors, for example, orthostatic albuminuria occur occasionally or frequently when one stand. It can disappear when one changes position. Functional proteinuria occurs after one has strenuous exercise, fever, or a cold. When his or her temperature goes down to normal level, proteinuria will disappear. Pathological proteinuria refers to proteinuria when kidney disease or kidney damage involved in systemic disease.
Proteins, components of blood, are essential for various body processes. Normally, the kidneys block the passage of protein, keeping it in the blood for delivery to the body’s tissues and organs. In proteinuria, however, protein in the blood passes through the kidneys and into the urine. Higher than normal blood pressure is a common cause of proteinuria. The kidneys are damaged by the elevated blood pressure, which eventually results in the passage of protein into the urine.
Other causes of proteinuria include diabetes, kidney infection, or other types of kidney inflammation. Left untreated, conditions that cause proteinuria can lead to a severe condition, end-stage renal (kidney) disease.
Proteinuria is a serious medical condition. Left untreated, proteinuria may lead to serious or life-threatening conditions. Seek immediate medical care for serious symptoms including difficulty urinating (dysuria), inability to urinate, difficulty breathing (dyspnea) or shortness of breath, lethargy or altered mental status, or chest pain or pressure.
Seek prompt medical care if you are being treated for proteinuria but mild symptoms recur or are persistent.
If you have the symptom proteinuria, you have to diagnosis what are the causes and then receive an early and proper treatment to prevent it from developing into irreversible situation.
