Kidney is an important part of the body. It will bring great effects to
patients if something is wrong with their kidneys. Edema is one of the clinical
symptoms of Chronic Kidney Disease. Why does edema occur in the patients with
Chronic Kidney Disease?
Kidney is the main organ with the function of excreting water and sodium of
the body. If the kidney works abnormally, the excretion amount of water and
sodium will decrease, which leads to edema caused by the retention of water and
sodium.
In general, Medicine Science thinks that the reasons of edema include: the
decrease of Glomerular Filtration Rate (GFR) leads to the retention of water and
sodium; the level of plasma albumin reduces, which leads to the decrease of
plasma oncotic pressure; the change of permeability of blood capillary all over
the body makes blood fluid enter into the interstitial space.
Must it be something wrong with the kidney if edema occurs?
Experts argue that there is no direct relation between edema and kidney
lesion.
So you do not need to worry too much if you have general edema that may be
caused by poor sleep at night at times. But it is possible to go to hospital to
take a syImmunotherapyatic inspect if the edema lasts long and is serious. Many
kinds of diseases are embodied in the details. It is difficult to make a correct
judgment just after one or two times simple diagnosis.
Once diagnosed with Nephrotic edema, patients should pay attention.
Nephrotic edema is a syndrome of Kidney Disease caused by Primary Glomerular
Nephropathy and other reasons. The characteristics are: the edema firstly
appears in loosened parts of tissues such as eyelids, face and ankles, which is
obvious in the morning. It may spread to legs and the whole body if serious. The
property of Nephrotic edema is soft and is easy to move, and it presents pitting
edema, which means that a pit will appear in the skin if you press it using your
finger.
The pathogenesis of this kind of edema is the decrease of plasma oncotic
pressure: a large amount of proteinuria causes hypoproteinemia, which leads to
the decrease of plasma oncotic pressure making body fluid filtration of blood
capillary increase. Then the body fluid reclaimed from the tissues decreases
obviously. Finally, it forms edema. Effective capacity of blood reduces: the
exosmosis of plasma makes the effective capacity of blood reduce, the secretion
of Natriuretic hormone decrease and the sodium resorption of renal tubules
increase, which aggravates the retention of water and sodium leading to
aggravate the edema.
Patients should pay attention to the edema caused by Kidney Disease. During
the edema, they should reduce the intake of sodium and potassium, if not the
result will be serious. So patients should prudently deal with edema.
