A symptom of high urine protein in women is that the urine becomes cloudy and frothy. Normal people also foam when they urinate, but this foam is relatively small and short-lived. The foam that is emphasized here is the kind of foam that is larger and lasts longer, like the kind of foam that comes from washing powder being washed up. This kind of foam is an abnormal state, and if this kind of foam appears, it is most commonly associated with the presence of protein in the urine in clinical practice. The more protein there is in the urine, the larger the foam may be and the longer it lasts. Patients with foam in the urine may have hypertension or edema, which suggests that the patient may be suffering from nephritis or nephrotic syndrome. The diagnosis of this type of disease is not based on clinical symptoms, clinical symptoms only provide a direction of suspicion, and the diagnosis requires the improvement of urinary routine and anti-nuclear antibody profile, immune function and other related tests.
