1. Excessive urination. According to expert analysis, the standard for healthy urination is 8 times a day. If it is not caused by drinking water and exceeds 8 times, it is called frequent urination. Frequent urination but low urine volume may be a problem with the bladder and urethra; Not only the frequency is high, but also the urine volume is low, which may be a metabolic disease in internal medicine, such as diabetes or polyuria. "Only those who urinate frequently and have a high urinary protein level on routine urine tests can have kidney problems.".
2. Excessive or insufficient urine output. The kidney is the organ that produces and excretes urine, producing and excreting urine at all times. A healthy kidney can maintain a balance between urine production and excretion. The normal daily urine volume of an adult is 1000 to 2000 milliliters. Too much or too little urine can indicate kidney problems.
3. Poor urination. "Bad urination is when you feel that your urine is not smooth, smooth, and can't be fully urinated, accompanied by discomfort in the lower abdomen. People who have experience of holding urine will have this experience.". Kidney deficiency is the main cause of unfavorable urination. If there are symptoms such as fatigue and weakness, cold limbs, fear of cold and chills, and soreness and weakness in the waist and knees, it is an unfavorable manifestation of kidney yang deficiency and gasification.
4. White urine. Normal urine should be pale yellow, while some people's urine is white, like rice, water, and milk, white and cloudy. "White urine without obvious pain is generally believed to be caused by kidney deficiency in traditional Chinese medicine, sometimes accompanied by a combination of dampness and turbidity, and kidney deficiency is the fundamental cause of white urine.".
5. Foam in urine. If you find a layer of tiny foam floating on the surface of urine for a long time, it may be an early symptom of nephritis or a hint that men have prostatitis. The foam in urination is the manifestation of proteinuria. If there is more foam in urination and there are obvious symptoms such as lumbar acid fatigue, the problem of kidney deficiency should be considered.
6. Low back pain after urination. This is a manifestation of kidney deficiency. According to traditional Chinese medicine, the kidneys are hidden in the two waists, and the waist is the mansion of the kidneys. People with kidney deficiency will have low back pain, and urination is presided over by kidney qi, which needs to be promoted. Therefore, after urination, kidney qi becomes more deficient, and low back pain is even more severe.
