I found out that the edema was a kidney disease.

Oedema is a common symptom of the body and may be the expression of a variety of diseases, of which kidney diseases are indeed one of the common causes of oedema. However, not all oedema is related to kidney disease. Through urine tests, it is possible to determine to some extent whether the oedema is related to kidney problems.I. Relationship between edema and kidney diseasesThe kidney is an important organ of the human body and is responsible for filtrating waste and excess water in the blood to form urine. When the kidney function is impaired, this may lead to the loss of proteins in urine, known as protein urine. The loss of proteins leads to water in blood permeating into the inter-organizational gap, causing edema. Thus, kidney diseases are one of the common causes of oedema.II. The role of urine testing in the diagnosis of edemaPee routines: The urine routines are the most basic urine tests, which provide many important information. Common urine tests show the color, transparency, weight and presence of abnormal elements such as proteins, red cells and white cells.Protein urine testing: The presence of proteins in urine is an important indicator of kidney disease. It is possible to determine whether or not there is protein urine, as well as the extent of the urine.III. How to conduct urine testsCollection of urine samples: A collection of morning urine samples is usually required, as the morning urine is more condensed and more reflective of the kidney function. The collection of urine should ensure that samples are not contaminated.(b) General urine examination: The sample of urine collected is sent to the laboratory for routine urine examination, and the doctor will determine whether there is an anomaly based on the results of the examination.24-hour urine protein Quantification: If urine is routinely shown to have protein Quantification may require a 24-hour urine protein Quantification test to more accurately assess urine protein excretion.IV. Interpretation of the results of urine testsNormal result: if there is no protein in the urine or only a very small amount of protein and there are no other anomalies, the oedema may not be related to kidney disease.Unusual results: If the protein content in the urine is abnormally high, this may indicate a kidney disease that requires further examination and diagnosis.V. OTHER EQUIPMENT PROBLEMSEven if the results of the urine examination were normal, the oedema caused by other causes could not be completely excluded. The following are some other causes that may cause oedema:Heart disease: Inadequate heart function may slow the blood cycle and cause edema to the lower leg.Hepatic disease: Hepatic disease may lead to a decrease in protein synthesis and cause oedema.Drug side effects: Certain drugs, such as hypertension, inflammatory drugs, etc., can cause edema.Malnutrition: Inadequate protein intake may also lead to oedema.ConclusionsUrea testing is an important means of determining whether edema is related to kidney disease. In the case of edema, urine tests should first be conducted to remove kidney diseases. However, even if the results of the urine examination are normal, the oedema caused by other diseases cannot be completely ruled out. Therefore, if the results of urine tests are abnormal or if oedema symptoms persist, medical treatment should be made in a timely manner and a more comprehensive examination and diagnosis conducted. Early detection and treatment can effectively control the progress of disease and improve the quality of life.
