Causes and Treatment for Renal Edema in Kidney Disease2013-09-16 15:49
Renal edema refers to a pathological phenomenon of too much liquid accumulated in tissue space or body cavity that caused by kidney disease. Edema is a common symptom of kidney disease. For many patients with Chronic Kidney Disease, their first time of going to the hospital is due to indescribable edema, and then they know they are suffering from kidney disease after a set of tests.
The Cause of Renal Edema
The cause of renal edema tends to fall into two categories:
1. The glomerular filtration rate drops, while the edema reabsorption of renal tubule is good, it thereby leads to the retention of water and sodium. Such cases are prevalent in nephritis patients.
2. The cause of edema is that a lot of proteins lost from urine, results in the drop of plasma osmotic pressure, and then water floats into the tissue space from the antrum. Such cases are prevalent in nephropathy syndrome.
The Characteristics of Renal Edema
Renal edema is an overall feature of kidney disease; it often gets worse as the aggravating of kidney disease. Renal edema is firstly observed in the eyelid, face, ankle and other areolar tissue. When it gets severe, the edema can involve in lower limbs, even the whole body. In addition, renal edema is often refers to pitting edema, it means if the patient presses down local skin can appear sag.
The Treatment for Renal Edema
1. Limit the intake of protein and water
Reduce the leakage of protein. If the intake of protein drops, the leakage of protein and the catatonosis will naturally decrease, then the edema will relief. But this approach is only helps avoid the deterioration of kidney, it can not repair damaged kidney tissue, so this is not a radical solution. Furthermore, long-term protein insufficient will cause malnutrition, hypoimmunity etc. So this approach is not a radical one.
2. Use diuretic
Diuretic can push the water discharge; it can reduce edema, high blood pressure and heart workload. Although the diuretic is effective, it can not repair kidney damage as well. So it is not a long-term and radical solution.
3. Limit the intake of water and salt
Sodium is rich in salt. Intake of too much salt can not only increase the storage of water sodium, but also cause high pressure. So the limitation of salt and water intake can help lessen the symptoms.
4. Immunization therapy
Currently, the immunization therapy is the most advanced approach in treating kidney disease. It cures the disease through repairing the damaged glomerulus membranes, organize the protein leakage. So immunization therapy can radically cure the renal edema.
Renal edema not only influences the regular life of kidney patients, but also aggravates kidney disease. So timely treatment is needed to help slow down illness condition.
