Usually, the appearance of foam in men’s urine, which disappears after 10 minutes, is abnormal. Normal human urine contains inorganic and organic salts as well as a large number of metabolites, and foam of varying sizes can be formed after urination, which usually disappears in about 10 seconds. If the foam in men’s urine exists for a long time, it can be suspected to be caused by nephritis, where a large amount of foam can be formed due to the high protein content in the urine. In addition, the above symptoms can also be suspected to be caused by diabetes, due to high urine sugar, foam can also appear, usually disappearing in about 15 seconds, so the disappearance of foam in men’s urine in 10 minutes is an abnormal phenomenon. If men experience foam in urine that disappears after 10 minutes, the patient should go to the urology department or endocrinology department of a regular hospital to clarify the specific cause and carry out relevant treatment under the guidance of a doctor.
