Nephrotic Syndrome is a disorder caused by damage to the small blood vessels in the kidneys that filter waste and excess water from the blood. When healthy, these small blood vessels keep blood protein from seeping into the urine and out of the body. When damaged, they don’t perform this function effectively, and protein can leak out of the blood and lead to swelling (edema). Signs and symptoms of nephrotic syndrome are as follows:
Nephrotic syndrome is caused by damage to the tiny blood vessels (glomeruli) of the kidneys. Kidneys are two bean-shaped, fist-sized organs situated at the small of the back, just below the rib cage, one on each side of the spine. Blood enters in the kidneys through arteries from the aorta, which is a large artery that carries blood from heart to other parts of body. Each kidney contains approximately 1 million glomeruli, each of which is attached to the opening of a small fluid-collecting tube (tubule). Each glomerulus (singular of glomeruli) and its tubule form a nephron, which is a functional unit of the kidneys. The glomeruli filters blood as it passes through kidneys. After being filtered by the glomeruli, blood travels through veins in the kidneys back to main bloodstream of the body which is directed towards heart. The filtered substances, after being modified by the tubules, and go through a tube from each kidney (ureter) to bladder ( a urine collection bag in the lower portion of abdomen) and pass out of the body by the process of urination. Every day about 2 liters of water, along with waste products and electrolytes, leave the body as urine. When your kidneys lose their filtering ability, dangerous levels of fluid and waste accumulate in your body, a condition known as kidney failure. Healthy glomeruli prevent protein of the body from leaking through the glomeruli. Protein plays and important role in maintaining fluid levels in the body. Protein also monitors the amount of water that is thrown out of the body through urine. When the glomeruli are damaged, it often loses this ability. Thus the result is loss of blood protein in urine leading to nephrotic syndrome. The nephrotic syndrome is characterized by:
The following medical conditions account for most cases of nephrotic syndrome:
Factors that may increase your risk of nephrotic syndrome include:
Possible complications of nephrotic syndrome include:
Prompt treatment of medical conditions that can lead to nephrotic syndrome, such as diabetes, lupus, kidney disease and amyloidosis, may prevent some cases of nephrotic syndrome. Changes in diet are necessary. A dietitian may be of good help in planning a proper diet. In general one may have to limit salt intake to help reduce fluid retention, swelling and blood pressure. The diet should be modified to decrease cholesterol and triglyceride levels from the blood. A supplement of vitamin D is advised. Living with nephrotic syndrome can be a difficult task all together for the patient as well as the family. One should make a team effort for the management of nephrotic syndrome. A team of specialist consultants in kidney diseases, dietitian may be of a good help. One may also benefit from joining a support group. Such a group can provide emotional support as well as latest developments in the treatment of nephrotic syndrome may be available if such groups are updated with latest information. |
