If you have proteinuria, take note of your other symptoms. They may help a doctor identify the underlying cause. Dehydration happens when your body loses too much fluid. Your body uses water to deliver nutrients, such as proteins, to the kidneys. The protein ends up in the urine instead. High blood pressure , or hypertension, can weaken the blood vessels in the kidneys. This decreases their ability to reabsorb protein, which then flows into the urine. Since high blood pressure develops slowly, you may not have symptoms for years.
If it becomes severe, it can cause headaches, shortness of breath , or nosebleeds. In some people, high blood pressure is a result of:.
Diabetes mellitus is a metabolic disorder that causes high levels of blood sugar. There are multiple types of diabetes, including type 1 and type 2 diabetes. With diabetes, high blood sugar forces the kidneys to filter the blood too much. This can cause kidney damage, allowing protein to leak into the urine.
Symptoms of diabetes depend on the severity and type. You may experience:. Proteinuria may indicate glomerulonephritis , or inflammation of the glomeruli. Normally, when the glomeruli filter blood, they reabsorb protein. If the glomeruli are injured, protein can pass through and enter the urine. Glomerulonephritis can cause a set of symptoms called nephrotic syndrome. In addition to proteinuria, nephrotic syndrome involves:. Glomerulonephritis may also cause hematuria , or red blood cells in the urine.
Hematuria makes urine look pink or cola-colored. Typically, glomerulonephritis happens when the immune system attacks the kidneys. Chronic kidney disease CKD is the progressive loss of kidney function. If CKD progresses, it can result in kidney failure. The immune system usually produces antibodies , also known as immunoglobulins, that fight foreign organisms.
