Oedema is a common physical phenomenon in which renal edema is closely related. Let’s talk about how the kidney edema happened today.
First, we need to know the function of the kidney. The kidneys are like a hard-working “cleaning little guard” who is responsible for filtrating the blood in our bodies and draining the metabolic waste and excess water from the blood to urine. When there is a kidney problem, this balance is broken and edema may appear.
Renal edema is a case of renal edema. This is mainly due to inflammation of kidney balls. Imagine the kidney ball is a fine sifter, which normally filters with precision. But once there’s inflammation, there’s a problem with the screen. Inflammation increases the filtration of kidney balls, like sifting holes, and something that should not be leaked, such as red cells and white cells, goes out, while also reducing the filtration of kidney balls. In this way, if the water and sodium in the body are not released, they accumulate in the body and cause edema. This oedema is usually the first place to appear in the face and eyelids, especially when people wake up in the morning and they find their eyelids swollen like little buns, which may be kidney inflammation. If the condition is severe, the edema can spread to other parts of the lower limb.
And kidney edema. This is mainly due to the large amount of protein lost from urine. The proteins in our bodies are like a little guard, keeping the balance of permeability in our blood. When kidney problems occur, large amounts of protein are reduced in plasma as urine is lost. It’s like an already tight sponge, it’s loose, and the water around it can see into the tissue. In such cases, edema usually begins with lower limbs, because of the effect of gravity, and water flows down. Slowly, the oedema will develop upwards, and when it is severe, it will swell up all over the body, and there will even be chest and abdominal water, which is very painful.
In addition, renal edema may be associated with kidney failure. When acute kidney failure occurs, the kidney suddenly loses normal working capacity, water and sodium cannot be discharged, and metabolic waste in the body accumulates, and the edema occurs quickly. Chronic renal failure is a long-term renal impairment and a slight decline in functioning, to a certain extent, also resulting in sodium sodium and oedema.
Poor renal blood circulation can also cause oedema. For example, the formation of renal veins prevents retrenchment of renal blood, increases stress in the kidney and affects normal kidney function, leading to oedema.
In addition to the kidneys themselves, there are other factors that can induce or exacerbate renal edema. For example, patients eat too much salt, have too much sodium in their bodies, burden their kidneys even more, and edema is more likely to appear or increase. Also, if patients take long-term medications that are harmful to their kidneys, they can also cause kidney damage and cause edema.
Overall, the causes of renal edema are multiple and are related to kidney inflammation, protein loss, kidney failure, blood circulation problems and some external factors. Understanding these causes helps us to detect problems in a timely manner, to protect kidney health and to reduce the burden of oedema. If an oedema is found, it is important that medical treatment be available in time for the doctor to identify the cause and treat it.
