No urinary protein but urine foamy for a long time may be related to physiological reasons, diabetes mellitus, urinary tract infection and so on.
1. Physiological reasons: when there is too much urine in the bladder, resulting in a full bladder, the bladder pressure is higher, and the urine speeds up when urinating. Or due to insufficient water intake, resulting in changes in urine concentration and urine solute. All of the above situations will form foam, but the foam is large or different sizes, short duration, and usually dissipate on its own.
2. Diabetes: most diabetic patients have positive urine sugar, which will increase the change of urine solute concentration and tension, resulting in a large number of bubbles in the urine for a long time.
3. Urinary tract infection: Inflammation occurs due to infection by pathogens. Caused by changes in the composition of the urine, such as the increase in white blood cells, will also affect the tension of the urine, will also make the urine long-term foam increase.
No urinary protein but urine long-term foam can also be seen in other causes, it is recommended to consult a doctor in a timely manner, follow the doctor’s instructions for relevant examinations, with the help of the doctor to clarify the nature, and targeted treatment or treatment.
