Foamy urine is not always present with high creatinine. Foamy urine does not necessarily occur due to the fact that elevated creatinine does not necessarily result in a change in the surface tension of the urine, nor does it necessarily result in proteinuria. Foamy urine is mainly caused by some substances in the urine, such as glucose, minerals, proteins and other substances that contribute to the increase in the tension of the urine, while elevated creatinine does not cause an increase in the surface tension of the urine, so elevated creatinine does not necessarily appear foamy urine. When the creatinine is elevated or foamy urine appears in the urine, you should go to the regular hospital in time, and under the guidance of the doctor to carry out the relevant examination, after a clear diagnosis, follow the doctor’s instructions standardized treatment. At the same time, you should avoid overwork in daily life, maintain a reasonable diet and pay attention to rest.
