If the patient has foamy urine but the urine test is normal, there is no need to worry about it. This is because some patients have foamy urine due to physiological reasons, for example, when the patient has to urinate more urgently, it will lead to some foam inside the urine, which does not require special treatment and is normal for routine urine tests. Of course, some patients, for example, have not had sex for a long time, may also lead to a certain amount of foam inside the urine, and this is also normal for routine urine tests. Some patients may also have foamy urine when they are sexually aroused, and a routine urinalysis will not reveal any abnormalities. For these physiological foamy urine, no special treatment is needed.
