Sometimes a person may find he has clear urine. As we know, the color of our urine in normal condition is light yellow, and if one person has kidney disease, there will be many changes in his urine. Therefore, many people may have this question: is clear urine a sign of kidney disease?
Kidney mainly consists of glomeruli and kidney tubules, and the kidneys in our body play an important role in cleansing our blood. Glomeruli can filtrate the metabolic wastes and toxic substances in the blood, and then these substances will be excreted through the urine. Kidney tubules can reabsorb the nutrients and water filtered by glomeruli, and then keep the balance of fluid and minerals in our body.
If a patient has kidney disease,his glomeruli may be damaged, so many wastes and toxic substances can not be filtered through kidney, such as urea, creatinine, and so on. As a result, the urine excreted by the patient will be clear. On the other hand, if the pathological changes occur in the kidney tubules, then kidney tubules will lose their function of reabsorption, and large output of water can make the concentration of patient’s urine low. The urine will also look clear. Thereby, clear urine can be a sign of kidney disease.
While, if a healthy person drinks too much water, there will be too much fluid in his body. Because kidney has the function of keeping the balance of fluid, excess water will be excreted through his urine. At the same time, the volume of metabolic wastes and toxic substances are normal. Certainly, this condition can also lead to urine’s low concentration, and people will also have clear urine. Therefore, not all cases of clear urine are the symptom of kidney disease.
Generally speaking, if a person’s clear urine is not continuous, especially he just has clear urine after he drinks too much water, he may not need to worry. However, if a person has long-term clear urine, he should doubt whether he has kidney disease, and it is better for him to have some examinations.
